Dear Governor and Legislative Leaders:
As requested by the Joint Legislative Audit Committee, the California State Auditor presents this audit report
on two of the State’s alternative energy and efficiency initiatives—the California Solar Initiative (solar initiative)
and the Clean Air Vehicle Decal Program (decal program). Specifically, we were asked to evaluate the extent to
which the goals of these programs are being achieved and who is benefitting the most from them.
This report concludes that the solar initiative, overseen by the California Public Utilities Commission (commission),
will likely install enough solar energy systems to reach its 2016 goal of 1,940 megawatts of installed solar capacity,
but other goals remain uncertain or inadequately quantified. For example, one goal is that the solar initiative should
lead to pollution reduction benefits. Although a 2010 consultant’s study concluded the solar initiative reduced
smog‑related emissions, it did not put those reductions in the context of the State’s overall emissions, nor
did it show how those reductions have resulted in measurable benefits to the State. Furthermore, some solar
initiative programs need further evaluation. For example, the commission established a Research, Development,
Deployment and Demonstration Program (research program). Although the research program is nearly complete,
the commission still has not selected a program evaluator to assess whether this program has contributed to solar
initiative goals. Finally, the California Solar Initiative Thermal Program will not install enough solar water‑heating
systems to meet its goal by the time the program ends in 2017.
The goal of the decal program—administered by the California Air Resources Board (Air Resources Board), the
California Department of Motor Vehicles (Motor Vehicles), the California Department of Transportation, and
the California Highway Patrol—is to encourage Californians to drive clean air vehicles by allowing certain
low‑emission vehicles to travel in carpool lanes with just one occupant. Although we found that the participation
in the decal program continues to grow, the Air Resources Board needs to measure the decal program’s effect
on air quality, and Motor Vehicles needs to conduct periodic cost analyses to ensure that decal fees cover all
program costs.
Finally, although both programs track geographic information on participants, neither collects demographic
data. Specific to the solar initiative, we found participation to be dispersed geographically throughout the State;
however, the limited demographic data that exists shows that participants in the solar initiative tend to be older,
wealthier, and have received more education than most Californians. As expected, participants in the decal
program largely reside in the counties that have freeways with carpool lanes, such as Los Angeles and Santa Clara.
With respect to the decal program, a recent consumer survey for a related incentive program for clean air vehicles
found that although the ages of respondents are somewhat evenly distributed, most respondents were male and
earned $100,000 or more per year.
Respectfully submitted,

As of September 2014 the solar initiative’s three programs, which
are aimed at increasing the installation of solar energy systems,
had 1,844 megawatts of installed or pending solar capacity, leaving
only 96 megawatts to be installed by December 2016 to meet
the commission’s goal. For the $50 million research program,
which provides funding for projects to support the solar initiative
2 California State Auditor Report 2014-124
February 2015
in achieving its megawatt goal, the commission established a
process for awarding and monitoring grants. However, with the
research program nearly complete, the commission still has not
selected a program evaluator to assess whether this program has
contributed to the solar initiative’s goals, as the program plan that
the commission adopted specified. As for the solar initiative’s
thermal program, the commission found that it will not accomplish
any of its goals due to low participation, which it attributes to
falling natural gas prices and the high installation costs for solar
water‑heating systems.
Concurrent with the 1,940‑megawatt installation goal, the solar
initiative also aims to create a self‑sufficient market for solar energy
in which solar energy systems will be a viable source of electricity
for residential and nonresidential utility customers by 2016. A
2014 consultant’s study addressing the state of the solar industry
determined that the solar initiative has helped overcome market
barriers to the adoption of solar energy systems in California.
Moreover, the study found evidence that the California solar
industry would be sustainable in the absence of solar initiative
incentives, although future legislative and regulatory rulings could
put that sustainability at risk.
Finally, Californians’ participation in the solar initiative should also
lead to pollution reduction benefits. A 2010 consultant’s study of
the solar initiative’s impact on pollution concluded that for that
same year, the solar initiative reduced smog‑related emissions.
Although reductions in pollution emissions are a benefit in and of
themselves, the consultant’s study does not put those reductions in
the context of the State’s overall emissions, nor does it show how
those reductions have resulted in measurable benefits to the State,
such as cleaner air or fewer health problems.
To provide incentives to increase the number of low‑emission
vehicles, California’s decal program provides stickers to certain
low‑emission vehicles so that they can travel in carpool lanes
with only one occupant. State law divides the responsibility
for administering the program among Motor Vehicles, the Air
Resources Board, the California Department of Transportation,
and the California Highway Patrol. State law does not require
any of these agencies to monitor the goals and objectives of the
decal program and none perform such an analysis. However, in
May 2014, the State reached the limit on the decals it can issue
for one of the eligible vehicle types—plug‑in hybrids—indicating
that, in addition to these vehicles’ gas savings, owners of these
vehicles may also value the access to carpool lanes that these
decals provide. Consequently, in 2014 the State increased the decal
limit for plug‑in hybrids from 40,000 vehicles to 70,000 vehicles.
Further, Motor Vehicles charges an $8 fee that is intended to fully
California State Auditor Report 2014-124 3
February 2015
fund its program costs. However, we determined that the current
fee is insufficient and, based on current costs, should be increased
to $15. We estimate that by raising the application fee to $15, Motor
Vehicles would have collected an additional $336,000 in fiscal
year 2013–14.
Further, a lack of comprehensive demographic data prevents us
from concluding whether the solar initiative and the decal program
have served a diverse population of Californians. However, the
limited demographic data that does exist shows that participants
in the solar initiative’s General Market Program tend to be largely
older, wealthier, and have received more education than most
California homeowners. Given the high up‑front costs of installing
solar energy systems, it is not surprising that the demographic
group participating in the solar initiative would fit this profile.
Financing such an investment, even after taking advantage of the
solar initiative incentive and federal tax credit, is probably difficult
for those with lower‑than‑average incomes.
With respect to the decal program’s capacity to appeal to a diverse
population, a recent consumer survey for a related incentive
program for low‑emission vehicles found that, although the ages of
respondents are somewhat evenly distributed, most respondents
were male and earned $100,000 or more per year. Because vehicles
that qualify for the decal program are generally more expensive
than equivalent conventional models, we would expect decal
program participants to earn a higher‑than‑average income.
Further, as expected, participants in the decal program largely
reside in the counties that have freeways with carpool lanes, such
as Los Angeles and Santa Clara. The Air Resources Board has not
studied the effect, if any, of the decal program on air quality nor is it
required to do so. However, our review of available data found that
some of the counties with the highest concentration of decals tend
to be in areas that have poor air quality and in areas that possess a
significant number of carpool lanes.
Recommendations
The Solar Initiative
To make certain that the research program contributes to the goals
of the solar initiative, the commission should conduct a program
evaluation before the remaining grant projects are completed.
4 California State Auditor Report 2014-124
February 2015
Because the thermal program has not been successful in meeting
the goals outlined in state law, the Legislature should consider
whether it wants to continue authorizing the collection of
ratepayers’ money to fund the program.
To show how air pollution emissions reductions related to the solar
initiative benefit the State, the commission should include in future
reports the measurable benefits of those reductions.
The Decal Program
To learn whether the decal program helps to reduce the State’s air
pollution, the Legislature should require the Air Resources Board to
research whether there is a relationship between decal usage and a
change in the State’s air quality.
To ensure that the decal fee is sufficient to reimburse program
costs, Motor Vehicles should periodically perform a full cost
analysis of the decal program and update the fee accordingly.
Agency Comments
The commission and Motor Vehicles generally agreed with our
conclusions and recommendations; however, the commission
asserted it may have difficulty implementing our recommendation
that it should include the measurable benefits of pollution
reduction in future reports. We had no recommendations for the
Air Resources Board and it did not to respond to our report.
California State Auditor Report 2014-124 5

Introduction
Background
In 1999 the Legislature declared that California’s urban air quality was
the worst of any state in the United States, with more than 80 percent
of the population living in areas that do not meet federal or state
air quality standards. In 2005 former Governor Schwarzenegger
signed an executive order establishing greenhouse gas reduction
targets, including a reduction of greenhouse gas emissions by 2050
to 80 percent below 1990 levels. Over the last several years the
Legislature has enacted several incentive programs to help achieve
the State’s air quality and climate goals, such as the California Solar
Initiative (solar initiative) and the Clean Air Vehicle Decal Program
(decal program), which encourage the use of solar energy and the use
of low‑emission vehicles, respectively.
Senate Bill 1 (Chapter 132, Statutes of 2006) established three solar
programs in an effort to encourage the use of solar electricity through
the installation of solar energy systems on residential and nonresidential
buildings. As Table 1 on the following page shows, the programs are
known collectively as the Go Solar California campaign, whose goal is to
create 3,000 megawatts of installed solar capacity by
2016. The text box provides some perspective on how

California State Auditor Report 2014-124 7
February 2015
The solar initiative has five program components, as Table 1
shows. The General Market Program, which has the largest budget
of all solar initiative programs, provides monetary incentives to
encourage residential and nonresidential customers to install solar
energy systems. Furthermore, subsequent legislation mandated
that the commission set aside at least 10 percent of solar initiative
funding for incentives to install solar energy systems on low‑income
residential housing. As Table 1 indicates, this legislation resulted
in the commission developing the Single‑Family Affordable Solar
Homes Program (single‑family program) and the Multifamily
Affordable Solar Housing Program (multifamily program).
Additionally, Senate Bill 1 set aside $50 million for the Research,
Development, Deployment and Demonstration Program, which
provides grants for solar technology projects that would assist
the solar initiative in achieving its megawatt and sustainability
goals. Finally, the Legislature created the California Solar Initiative
Thermal Program (thermal program) to promote the installation
of solar water‑heating systems to reduce demand for natural gas,
electricity, and propane.
In creating the solar initiative, the Legislature required the
commission to establish declining dollar amounts of incentive
levels. The purpose for declining incentives is that as the solar
market grows, it is expected that solar installation costs will decline
to the point where monetary incentives are no longer needed
to encourage customers to install solar energy systems. State
law requires the commission to reduce the dollar amount of the
incentive levels by 7 percent annually over the duration of the
solar initiative, and the incentive level must be zero by the end of
the program in December 2016. To comply with this mandate, the
commission created declining incentive levels for each customer
sector—residential and nonresidential. Data from the commission
shows that as of October 2014, the program administrators had
exhausted nearly all available incentives. In fact, according to the
commission, PG&E is no longer accepting any solar initiative
applications for the General Market Program. While SCE and
SDG&E are no longer accepting residential applications, they
continue to accept nonresidential applications.
As Table 2 on the following page shows, the average size of a
residential solar energy system installed under the solar initiative
program is about 5 kilowatts, and it costs about $25,350 per
residence to install, if purchased. At the October 2014 solar
initiative incentive level of $200 per kilowatt, the participant
receives an incentive of $1,000 to offset the installation cost. By
taking the Federal Residential Renewable Energy tax credit, the
participant may also claim on his or her federal income taxes up
to 30 percent of the solar energy system installation costs less the
solar initiative incentive, or about $7,305 for the average installation.
8 California State Auditor Report 2014-124
February 2015
Therefore, we estimate that for a typical residential participant, the
net cost of installing a solar energy system is approximately $17,045
as of October 2014.

* As of the second quarter of 2014, the average completed costs for a residential, customer‑owned
solar energy system installation under the solar initiative was $5,070 per kilowatt. The average
size of a solar energy system was approximately 5 kilowatts for residential installations under the
solar initiative’s General Market Program.
† The incentive level for the solar initiative was current as of October 2014.
Under the Commission’s Oversight, Six Program Administrators
Implement the Solar Initiative
As Table 1 outlines, the commission oversees the implementation
of the solar initiative’s five program components. Six program
administrators—PG&E, SCE, Center for Sustainable Energy,
GRID Alternatives, Itron Inc., and SoCalGas—administer the
five programs. To fund the solar initiative, the commission
established that four investor‑owned utilities—PG&E, SCE,
SDG&E, and SoCalGas—are responsible for collecting a portion
of the budget based on their share of retail electric and gas sales.
Customers of these four investor‑owned utilities fund the solar
initiative through a surcharge on their bills. However, low‑income
customers enrolled in ratepayer assistance programs through
these investor‑owned utilities are not required to pay the solar
initiative surcharge.
The commission oversees the program administrators’
implementation of the solar initiative. Commission staff perform
a variety of activities in support of the solar initiative, such as
establishing program rules and customer eligibility, developing
evaluation plans, issuing requests for proposals, and selecting
firms to conduct program evaluations. The commission also
must submit to the Legislature an annual assessment of the
solar initiative’s success, which includes the program’s overall
costs and benefits, its environmental benefits, its impacts on the
California State Auditor Report 2014-124 9
February 2015
electricity grid, any progress toward reaching each program’s
goals, and recommendations for improving the programs. The
commission receives reimbursements from the four investor‑owned
utilities for its activities related to the oversight of the solar
initiative. From 2007 through September 2014, the commission
reported spending $5.4 million for these oversight activities.
Because of this reimbursement and the fact that customers of
investor‑owned utilities fund the solar initiative, the commission
states that there are no additional costs to the State.
The Solar Initiative Serves Residential and Nonresidential
Participants Statewide
The solar initiative provides incentives for solar energy systems—
ranging from 1 kilowatt to 1 megawatt in size—to eligible residential
and nonresidential customers of PG&E, SDG&E, and SCE. As
Table 3 indicates, from January 2007 to September 2014, residential
participants installed about 143,000 solar energy systems,
representing 96 percent of all installations. However, because
residential homes tend to have smaller solar energy systems, these
143,000 installations account for only 41 percent of the megawatt
capacity installed under the solar initiative. The remainder of the
megawatt capacity, more than 59 percent, stems from installations
by nonresidential participants—commercial, government, and
nonprofit entities.

February 2015
In addition, data from the commission shows that the solar initiative
issued or reserved incentives for more than 149,000 solar energy
systems throughout the State, with many incentives concentrated in
southern and central California. As Table A.1 beginning on page 39
in the Appendix shows, the top five counties based on the total
amount of incentives are Los Angeles, San Diego, Riverside, Santa
Clara, and San Bernardino. Predictably, many of California’s most
populated counties received the most incentives. Overall, participants
reside in 53 out of the 56 counties that the three investor‑owned
utilities serve, illustrating the solar initiative’s success in attracting
participants throughout the State. The commission’s data indicates
that from January 2007 to September 2014, the solar initiative
awarded approximately $1.023 billion in incentives under the General
Market, single‑family, and multifamily programs and reserved an
additional $956 million for future incentive payments. Combined,
the incentives total $1.979 billion and represent about 93 percent of
these programs’ $2.135 billion incentive budget. The solar initiative
has approximately $156 million in available incentives to award as of
September 2014.
For the thermal program, the commission’s data shows that the
solar initiative issued or reserved incentives for more than 2,400
solar water‑heating installations throughout the State, with many
incentives concentrated in central and southern California. As
Table A.2 beginning on page 41 in the Appendix shows, the top
five counties with participants receiving solar water‑heating
incentives are Los Angeles, San Diego, Alameda, San Francisco, and
Riverside. Overall, the commission’s data shows that the thermal
program awarded approximately $24.4 million in incentives and
reserved an additional $13.1 million for future incentive payments
to program participants in 44 counties from May 2010 to
September 2014. Combined, the incentives total $37.5 million and
represent only 12.3 percent of the program’s $305.8 million
incentive budget. Thus, the thermal program has approximately
$268.3 million in remaining solar water‑heating incentives to award
as of September 2014. Although the thermal program has spent only
a small portion of its allocated budget, the commission requires
that investor‑owned utilities collect funds based upon actual annual
expenditures from the prior year, which prevents the over collection
of funds from ratepayers.
The Decal Program Encourages the Use of Low‑Emission Vehicles
State law authorized the decal program, effective in 2000, to
increase the use of low‑emission vehicles at little or no cost
to the State. The decal program grants carpool lane access to
single‑occupant vehicles that meet certain emission standards.
Since the program’s inception, the State has offered three different
California State Auditor Report 2014-124 11
February 2015
decal designations that recipients must display on their vehicle to
use carpool lanes. As Table 4 shows, in 2000 state law authorized
access to carpool lanes to an unlimited number of inherently
low‑emission vehicles that do not use a traditional gasoline engine.
In 2002 the California Department of Motor Vehicles (Motor
Vehicles) issued regulations that assign a white decal to vehicles
that meet these emission standards. As the Legislature expanded
carpool lane access to qualifying hybrid vehicles that run on both
conventional fuels and electricity, Motor Vehicles subsequently
amended its regulations to assign these vehicles a yellow decal. The
yellow decal program ended in July 2011. Effective January 2012
state law granted carpool lane access for a new classification of
hybrid electric vehicles that can be charged by an outside power
source. In October 2012 Motor Vehicles established a green decal
for vehicles that meet this emission standard.

State law divides the responsibility for administering the decal
program among the California Air Resources Board (Air
Resources Board), Motor Vehicles, the California Department
of Transportation (Caltrans), and the California Highway Patrol
(Highway Patrol). Motor Vehicles is responsible for processing
decal applications, which vehicle owners and dealerships submit
along with an application fee designed to cover the program’s
actual costs. The Air Resources Board maintains a list of vehicle
makes and models that qualify for the different decal programs,
and Motor Vehicles uses that list to verify the eligibility of each
applicant’s vehicle. Federal law requires Caltrans to monitor federal
performance requirements for carpool lanes, which involves
12 California State Auditor Report 2014-124
February 2015
monitoring the vehicle speeds of carpool lanes and reporting
that information to the U.S. Secretary of Transportation. Finally,
Highway Patrol’s role is to prevent the unauthorized use of carpool
lanes by ineligible vehicles, such as single‑occupant vehicles that do
not display a decal.

Audit Results
Although the California Public Utilities Commission Has Made
Progress Toward Achieving Some Solar Initiative Goals, Other Goals
Remain Uncertain or Inadequately Quantified
In creating the California Solar Initiative (solar initiative),
Senate Bill 1—enacted as Chapter 132, Statutes of 2006—established
the five goals shown in Table 6 on the following page. The California
Public Utilities Commission (commission) will likely meet the
megawatt and self‑sufficiency goals of the solar initiative, but other
goals remain only partially achieved, or not enough data exist to
determine whether the commission has fulfilled those goals. For
example, as of September 2014, the solar initiative had reached
95 percent of its megawatt goal, and the program still has nearly
two years before it expires. However, other solar initiative goals
have not been achieved. For instance, a 2011 consultant’s study
found that the solar energy systems have mostly been cost‑effective
for residential participants but not for nonresidential participants.1
Likewise, although the commission is working to address
deficiencies, it still does not have effective means for measuring the
impacts of solar energy on the electricity grid. Finally, although a
2010 consultant’s study points to pollution reductions due to the
solar initiative, it does not show how, or if, those reductions have
benefited the State in terms of cleaner air or improved health.2
The solar initiative will likely meet its goal to install 1,940 megawatts
of solar capacity by the end of 2016, when the program will
expire. Based on commission data, as of September 2014, the
solar initiative has installed 1,573 megawatts of solar capacity, and
271 megawatts are pending installation—a total of 1,844 megawatts
of solar capacity—for both residential and nonresidential
participants. As Figure 1 on page 17 illustrates, except for a slight
dip in 2013, the amount of megawatt capacity installed per year
has increased every year since the program began in 2007 through
September 2014, although the total for the latter year includes
pending applications. If all 271 megawatts of solar capacity
in pending applications are installed, the solar initiative would need
to install 96 megawatts by the end of 2016 for its goal to be met.
Using historic participation rates, we believe that the solar initiative
will achieve its 1,940‑megawatt capacity goal by its expiration
in 2016.

* The commission asserts that the first two goals are primary and the remaining three are secondary.
The Solar Initiative Is on Track to Fulfill Its Goal for Megawatt Capacity
Legislation passed following Senate Bill 1 required that at least
10 percent of solar initiative funding be used for the installation
of solar energy systems on low‑income residential housing. As a
result of this legislation, the commission created the Single‑Family
Affordable Solar Homes Program (single‑family program) and
the Multifamily Affordable Solar Housing Program (multifamily
program). The commission’s decision to implement the solar initiative
stated that the General Market Program was to cover 90 percent
of the 1,940‑megawatt goal, implying that the single‑family and
multifamily programs would provide the remaining 10 percent, or
190 megawatts. However, the commission explained that it did not
establish specific megawatt goals for the single‑family and multifamily
programs because the monetary incentives for these programs are
greater in value than the incentives for the General Market Program,
California State Auditor Report 2014-124 17
February 2015
and as a result these programs would run out of funding before
reaching 190 megawatts.3 In fact, the single‑family and multifamily
programs have used almost 75 percent of their allocated funding,
but have installed only 35 megawatts of capacity and have another
8 megawatts pending installation as of September 2014. With regard
to the legislative mandate requiring the low‑income programs to
spend at least 10 percent of the solar initiative’s funding, according to
the commission’s data, these two programs have spent $160.7 million,
or 74 percent, of their combined solar initiative funding of
$216.7 million as of June 2014. According to a commission analyst,
the remaining incentives for the multifamily program have been
completely reserved, and the expectation is that the same will be true
of the single‑family program.

18 California State Auditor Report 2014-124
February 2015
A Commission Consultant Determined That the Solar Initiative Was
Instrumental in Overcoming Market Barriers, but the Solar Industry May
Not Remain Sustainable Should New Barriers Arise
A 2014 consultant’s study concluded that from 2007 through 2012,
the solar initiative helped overcome market barriers to solar energy
system adoption.4 To make this determination, the study looked at
four expected outcomes—reduced costs to customers, increased
customer confidence in solar equipment, an expanded supply chain,
and an increase in overall market size—that needed to be evident
to show that market barriers had been reduced. For example, in
examining one of the four expected outcomes, the study found
that the costs for both residential and nonresidential solar energy
systems have declined from the inception of the program through
2012. Based on the commission’s data, we calculated that the cost
of an average solar energy system installation for a residential
customer—a 5‑kilowatt system—dropped from $56,000 in 2007 to
about $25,000 in 2014. Similarly, the cost of an average solar energy
system installation for a nonresidential customer—a 152‑kilowatt
system—dropped from $1.6 million to $645,000 during the same
time period.
A commission consultant concluded Further, the consultant concluded that the California solar industry

will remain sustainable without the More specifically, it concluded that an increasing number of
solar initiative incentive. installations do not rely on solar initiative incentives, and as
worldwide regulatory and market forces affecting the manufacture
of solar energy systems have led to price declines, the supply
chain has expanded to meet growing customer demand for
solar energy systems. As explained in the Introduction, the solar
initiative is designed so that monetary incentives decline annually
in dollar value and reach zero by December 2016. Data provided
by the commission show that the number of solar energy system
installations increased through 2013 despite decreases in the solar
initiative’s incentives, which provides additional support that the
consultant’s conclusion is valid. Furthermore, the study explained
that solar installers have expanded their physical operations in
California to enable them to respond to growing market demand
that spans the entire State.
However, according to the 2014 consultant’s study, the solar industry
may not remain sustainable should new barriers arise in the market.
In particular, the study cites uncertainty surrounding the future of
California’s net energy metering policy and its impact on the electric
rate structure. According to the commission, net energy metering is

March 27, 2014.
California State Auditor Report 2014-124 19
February 2015
a billing arrangement that allows customers to use solar generation
to reduce their electricity bill. Further, according to the study, some
net energy metering customers are able to generate enough electricity
to reduce their bill payments close to zero, allowing these customers to
avoid paying fixed costs for maintaining the electricity infrastructure.
Although it states that net energy metering has been instrumental
in helping to drive the demand for solar energy systems, the study
explains that recent legislative and regulatory decisions related to net
energy metering are creating significant concerns about the long‑term
viability of the solar market. According to this study, changes in the Changes in the benefits that net
benefits that net energy metering offers could make solar energy energy metering offers could
systems less advantageous for consumers to install and for investors make solar energy systems less
to finance, thus curbing participation in the solar initiative and advantageous for consumers to
threatening its sustainability. Specifically, 2013 legislation authorizes install and for investors to finance,

participants that will ensure continued growth in the use of solar solar initiative and threatening
energy systems while at the same time accounting for the systems’ its sustainablility.
costs and benefits, which may include net energy metering.5 The
legislation also states that the commission may consider changes to the
retail rate structure, which could affect compensation for participants
in net energy metering because current rate structures benefit them.
Nevertheless, the study concludes that a prompt decision by the
commission about the future of changes to net energy metering will
add stability to the market. According to a commission analyst, the
commission is currently conducting an assessment of how changes
to net energy metering—or the elimination of net energy metering—
might affect the sustainability of the State’s solar market. The
commission expects to complete its assessment by April 2015.
Installation of Solar Energy Systems Is Consistently Cost‑Effective for
Residential Participants but Will Not Be Cost‑Effective for Nonresidential
Participants Until 2018
A 2011 consultant’s study assessed whether installing solar energy
systems will be cost‑effective to both residential and nonresidential
participants starting in 2008 and each year thereafter until the solar
initiative expires in 2016. The consultant also forecasted whether
installing solar energy systems after the solar initiative incentives are
no longer available to both residential and nonresidential participants
will be cost‑effective for each year between 2017 and 2020.6 The
consultant’s analysis compared the relevant costs of solar energy
systems’ installation to their financial benefits, which include lowered
electricity bills, solar initiative incentives, and tax credits.
5 Assembly Bill 327 (Chapter 611, Statutes of 2013).
6 The 2011 consultant’s study does not address cost‑effectiveness after 2020.
20 California State Auditor Report 2014-124
February 2015
The consultant’s study concluded that the benefits residential
participants derived from installing solar energy systems have
outweighed and will continue to outweigh the costs of installation
for every year between 2008 and 2020. Additionally, the consultant
forecasted that by the time the solar initiative expires in 2016, the
decline in the costs to install a solar energy system, combined with
increasing electricity rates, will continue to make the program
cost‑effective for many residential participants even in the absence
of the solar initiative incentives and state and federal tax credits.
The continued decrease in the costs to install a solar energy system
is consistent with our determination that installation costs have
decreased, which we based on the commission’s data and described
in an earlier section.

commission consultant. the difference in the monthly electricity savings experienced by the
two different types of participants. Specifically, the rate structure is
more favorable to a residential participant taking advantage of the
solar initiative program than it is to a nonresidential participant.
Additionally, although the federal tax credit for nonresidential
participants is not completely expiring in 2016 as it is with
residential participants—it is being reduced from 30 percent of the
total cost of the solar energy system to 10 percent—the consultant
concluded that this decrease in the tax credit will not significantly
affect the cost‑effectiveness of installing solar energy systems for
nonresidential participants. In fact, the consultant concluded that
after 2017, the key driver for the change in the cost‑effectiveness
of solar energy systems for nonresidential participants—as for
residential participants—will be electricity rate increases and the
continued decline in the cost of solar energy systems.
The Solar Initiative’s Impacts on the State’s Electricity Grid and Its
Pollution‑Reduction Benefits Are Not Quantified Adequately but
Appear Minimal
A 2013 consultant’s study determined that the utilities have not
quantified adequately the impacts of distributed power generation
systems on the electricity grid—including the increased solar
power capacity that the solar initiative created.7 The study defines
7 Black & Veatch Holding Company, Biennial Report on Impacts of Distributed Generation, May 2013.
California State Auditor Report 2014-124 21
February 2015
distributed power generation systems as noncentralized electricity
power production facilities of less than 20 megawatts, which would
include the installation of residential solar energy systems under
the solar initiative. According to the consultant’s study, although
these distributed power generation systems could have a number
of potential impacts on the electricity grid, these impacts have not
been adequately quantified but are believed to be relatively low. The
study concludes that several conditions could be responsible for
the lack of observed impacts, including the fact that utilities do not
have the appropriate tools to collect and evaluate systematically the
data on problems or benefits attributable to these distributed power
generation systems and that formal research and development are
required to better understand the issues and benefits correlated
to distributed power generation systems. As a result, neither the
commission nor the utilities know with certainty how increases in
the power associated with distributed power generation systems,
including those installed under the solar initiative, will affect the
State’s electricity grid.
The consultant also pointed to a number of emerging technologies
that may alleviate some of the negative impacts and barriers to
greater deployment of distributed power generation systems.
A commission analyst stated that these technologies are key to
gathering data about the impacts of distributed power generation
systems. In addition, the analyst indicated that although the
Legislature and the commission have initiated some efforts to
encourage the adoption of these technologies, they are costly
and largely unproven, making it difficult for utilities to commit to
the technologies’ widespread adoption. Because of uncertainties
surrounding grid impacts and available technologies, the
commission plans to continue to monitor the impacts and include
any updates in its consultant’s next report to the Legislature, which
is due in 2015.
Further, although the 2010 consultant’s study mentioned earlier Although the 2010 consultant’s
determined that the solar initiative reduced pollution, the study determined that the solar
consultant did not attempt to link those reductions to specific initiative reduced pollution, the
benefits, such as cleaner air or fewer health problems. Specifically, consultant did not attempt to

problems and deteriorated air quality, respectively. The consultant
based this conclusion on an estimate of the amount of pollutants
that an electricity plant using natural gas would have emitted to
generate an equivalent amount of electricity. Although reduced
emissions are a benefit in and of themselves, the reductions cited
in the 2010 study are small relative to the State’s overall emissions
of those two pollutants. For example, according to the California
Air Resources Board (Air Resources Board), the State emitted
22 California State Auditor Report 2014-124
February 2015
557,000 tons of particulate matter and 848,000 tons of oxides
of nitrogen in 2010. Thus, the 56 tons of reduced emissions in
2010 represent a very small amount of the State’s overall annual
emissions of particulate matter and oxides of nitrogen. Moreover,
according to the commission, the 2010 study does not provide any
additional data showing how these reductions may have translated
into other types of measurable benefits, such as evidence of reduced
respiratory health illnesses or increased clean air days, which
further contributes to the difficulty of determining the significance
of the reductions.
Other Solar Initiative Programs Need Further Evaluation
The remaining solar initiative programs either have not received
evaluations or have clearly not met expectations. Specifically, under
the Research, Development, Deployment and Demonstration
The commission has awarded Program (research program), the commission has awarded
$33 million for research projects $33 million for research projects without evaluating whether
without evaluating whether the the completed projects contributed to solar initiative goals. The
completed projects contributed to California Solar Initiative Thermal Program (thermal program),
solar initiative goals. which aims to reduce natural gas, electricity, and propane
usage by promoting the use of solar water‑heating systems, has
underperformed. As a result, the thermal program is unlikely to meet
its goals by the program’s end date in 2017, even if the commission
implements additional changes to the program’s design.
No Independent Evaluator Has Monitored the Research Program to
Determine Whether It Contributes to the Solar Initiative
The commission has not yet assessed whether the $50 million
research program has contributed to the solar initiative’s goals. To
comply with Senate Bill 1, the commission established a process for
awarding and monitoring grants through the research program,
which was intended to fund projects that would help the solar
initiative achieve its goal of 1,940 megawatts of installed capacity.
Additionally, the 2007 commission decision implementing the
research program specified that both a program administrator and an
evaluator be chosen to assist the commission with the administration
and evaluation of the entire research program. The evaluation was
to take place once every three years. According to the commission,
although it selected a program administrator, Itron Inc. (Itron), it has
not selected a program evaluator. The commission indicated that it
will wait until a sizable portion of the grants are completed before
using an independent evaluator to conduct an evaluation. According
to the commission, as of January 2015, it had not issued a request
for proposals or taken any other steps toward securing a program
evaluator for the research program.
California State Auditor Report 2014-124 23
February 2015
To determine whether the projects selected for research program
funding have contributed to solar initiative goals, we evaluated
a selection of completed projects and found that they generally
supported these goals. According to Itron, through the solicitation
process, the research program has awarded $33 million in grant
funds to 36 projects. Of these projects, 13 are complete and one was
cancelled. The commission has directed the remaining research
program funding to administrative expenses, including the eventual
hiring of a program evaluator. The entities awarded funding by Itron
included the University of California, the federal government, and
private entities. Our review of three completed research program
projects found that they all addressed the goals of the solar initiative.
Specifically, two of the projects resulted in tools and research meant
to help utilities better integrate solar energy into the electricity grid,
and the third created a software program that utilities can use to
create programs encouraging the installation of solar energy systems By not evaluating the entire
on retrofitted homes. Although our review of these three projects research program every three years
suggests that the projects did support solar initiative goals, a more as originally intended, the

commission to meet the goals of the solar initiative, nor can it make
any necessary adjustments.
In addition to the $33 million it awarded in grants, the commission,
when it implemented the research program in 2007, awarded
$10 million to help finance construction of the Helios Solar Energy
Research Center (Helios center)—located in Berkeley—which is
led by Lawrence Berkeley National Laboratory and University of
California, Berkeley. The research performed at this facility will focus
on developing breakthrough solutions to low‑cost solar electricity
generation. Although the $10 million award accounts for only
about one‑tenth of the Helios center’s estimated $100 million to
$140 million overall cost, it makes up one‑fifth of the $50 million in
total research program funds. Furthermore, although approved
by the commission at a public hearing, the decision to support
the Helios center bypassed the process that the commission itself
established for the awarding of funds to research program projects.
In its decision, the commission stated that the funding it provided
to support the Helios center was consistent with its goals to allocate
funds expeditiously. Furthermore, the commission stated that the
Helios center was well positioned to start up research projects
quickly and thereby help achieve the solar initiative’s megawatt
goal by 2016. However, the commission did not require that any
specific research be undertaken. According to the Lawrence
Berkeley National Laboratory, construction of the facility began
24 California State Auditor Report 2014-124
February 2015
in August 2012, and the facility is scheduled to open by May 2015,
eight months after the originally scheduled completion date and
nearly eight years after the commission awarded the funding to the
Helios center. Because the facility is not yet complete, we cannot
determine whether research conducted there will be able to develop
cost‑effective solar energy technologies that contribute to solar
initiative goals by the end of the program, as stated by the
commission. Thus, the commission directed a large portion of
the program’s funding to a project whose impact is not likely to be
known before the solar initiative largely ends in 2016.
Despite the Commission’s Efforts, the Thermal Program Will Not Install
Enough Solar Water‑Heating Systems by Late 2017 to Meet Its Goals
Prices for natural gas have dropped significantly, but the installation
costs for solar water‑heating systems for single‑family homes have
not decreased. For these reasons, the commission’s January 2014
report to the Legislature (2014 commission report) concludes that the
thermal program will not install enough solar water‑heating systems
to reach either of its two goals. As the Introduction explains, the
Legislature created the thermal program to promote the installation
of solar water‑heating systems, which reduce the demand for natural
gas, electricity, or propane. The thermal program has two goals, each
of which corresponds to the energy source of the solar water‑heating
system: The first goal is to achieve by the end of 2017 the installation
of solar water‑heating systems that displace 22.6 million therms of
natural gas annually, which the commission
estimated was the equivalent of 200,000

systems installed to replace water heaters powered by natural gas
displace only 2.7 million therms annually. This figure represents
just 12 percent of the program’s annual natural gas goal to displace
22.6 million therms. Furthermore, our analysis shows that solar
water‑heating systems installed to replace electric‑powered water
heaters displace only about 928,000 kilowatt‑hours of electricity
annually. This figure represents just 0.3 percent of the program’s
goal to displace annually 275.7 million kilowatt‑hours. These results
corroborate the 2014 commission report’s conclusion that the
thermal program will not meet its goals.

incentives for multifamily or commercial systems by 13 percent.
In addition, the commission expanded the scope of the program
by allowing participants to receive incentives for other solar
water‑heating technologies, such as non‑single‑family swimming
pools. Additionally, for 2011 to 2013, the commission authorized a
$10 million statewide marketing and outreach campaign to increase
awareness of the thermal program.
In reviewing the incentive levels and progress of the thermal program,
the 2014 commission report contained a series of observations,
including the following three: First, the commission observed that the
2012 increase in incentive levels did not lead to a significant increase
in program participation. Second, the commission observed that the
substantial marketing and outreach campaign was largely ineffectual
for increasing participation among single‑family systems. Lastly,
the commission stated that expanding eligibility to new thermal
technologies may increase participation, but that it was too soon to
determine its impact. Despite the commission’s efforts to expand
participation, we found that as of September 2014, about $37.5 million,
or 12 percent, of the $305.8 million thermal incentive budget had been
awarded. As described in the Introduction, the commission requires the
investor‑owned utilities to collect the funds based upon actual annual
expenditures from the prior year to prevent an overcollection of funds
from ratepayers. Additionally, the 2014 commission report indicates
that further program design changes, even if implemented in full, still
may not be enough to spur program participation. Given the lack of
participation in the thermal program, the largely ineffectual program
design changes, and the fact that the program is unlikely to meet its
goals, the Legislature should consider whether it wants to continue
authorizing the collection of ratepayers’ money to fund the program.

The Clean Air Vehicle Decal Program Needs Periodic Evaluations to
Identify Its Strengths and Weaknesses
Like the solar initiative, the Clean Air Vehicle Decal Program (decal
program) attempts to improve the State’s air quality by offering
an incentive that encourages Californians to decrease vehicle
emissions by increasing the number of low‑ and zero‑emission
vehicles on the road. In helping to administer the decal program,
the California Department of Motor Vehicles (Motor Vehicles)
issues stickers, commonly referred to as decals, to purchasers of
clean air vehicles so that single occupants of those vehicles can use
highways’ carpool lanes. As discussed in the Introduction, state law
does not require any of the administering agencies to monitor the
goals and objectives of the decal program and none perform such
an analysis. Further, Motor Vehicles has not determined whether
fees for the decals are covering its program’s costs. In addition, the
California Department of Transportation (Caltrans) has reported
that the number of carpool lanes that do not meet federal speed
requirements is increasing, but it does not attribute this increase to
drivers who participate in the decal program. Lastly, although the
highest concentration of decal recipients live in areas that have not
attained certain air quality standards—including counties in the
Bay Area and Southern California—the Air Resources Board has
not studied the decal program’s impact on air quality.
Although No State Agency Measures the Decal Program’s Effectiveness,
Participation in the Program Has Increased in Recent Years
None of the four state agencies The Legislature intended the decal program to increase the number

As the Introduction outlines, state law divides the responsibility
for administering the decal program among Motor Vehicles, the
Air Resources Board, Caltrans, and the California Highway Patrol
(Highway Patrol). For example, Motor Vehicles is responsible for
issuing decals to qualifying vehicles, and the Air Resources Board
maintains the list of makes and models of qualifying vehicles. Motor
Vehicles’ chief of budgets (budget chief) stated that Motor Vehicles
has not performed a cost‑benefit analysis for the decal program
due to its limited, ministerial role of issuing decals as directed by
statute. According to the Air Resources Board, it supports the decal
program and believes that it is an important incentive to encourage
California State Auditor Report 2014-124 27
February 2015
the purchase of clean air vehicles, which are necessary to achieve the
State’s air quality and climate goals. The Air Resources Board further
explained that it has no statistical data showing the impact that the
decal program has had on reducing emissions through the increased
use of qualifying vehicles. However, the Air Resources Board directed
us to a survey conducted by the Center for Sustainable Energy
(center) between October 2013 and July 2014, that determined that
15 percent of survey participants credited carpool lane access as
the most important reason for purchasing an electric vehicle. The
survey further noted that participants reported that saving money on
fuel costs and reducing environmental impacts were the two main
reasons why participants purchased electric vehicles.
Because no state agency monitors the effectiveness of the decal Because no state agency monitors
program, our review of the program’s success was limited to the effectiveness of the decal
assessing the public’s demand for decals. As Table 4 on page 11 program, our review of the
in the Introduction indicates, the State currently offers two types program’s success was limited to
of decals—green and white—for vehicles meeting certain assessing the public’s demand
emission standards. State law, effective January 2012, authorized for decals.
Motor Vehicles to issue no more than 40,000 green decals to
eligible vehicles. In May 2014 the State reached this limit. The State
enacted a law in June 2014 to increase the limit on green decals to
55,000, a ceiling that Motor Vehicles reached in September 2014.
Also in September 2014, the governor signed another bill increasing
to 70,000 the number of green stickers Motor Vehicles could issue.
According to the Air Resources Board, the decal program is so
popular with consumers that there were more eligible applicants
than available decals, causing the Legislature to raise the limit
on green decals. The Air Resources Board also stated that in
enacting this legislation, the Legislature presumably had weighed
the merits of continuing the program and determined that the
benefits of doing so, such as encouraging the commercialization
of advanced‑technology vehicles, outweighed any costs associated
with this expansion of the decal program.
Furthermore, the public’s demand for white decals—available for
vehicles that use only electric batteries, hydrogen fuel cells, or
compressed natural gas—has also risen in recent years. However,
the State has not limited the number of white decals that can be
issued. Motor Vehicles’ data show that it issued nearly 13,400 white
decals from 2010 to 2012 and that demand increased in 2013 and
2014—it issued 18,200 and 26,400 decals, respectively, in those
years. The demand for decals indicated by Motor Vehicles’ data
appears to support the Air Resources Board’s view that the program
is popular with consumers and that it may encourage the purchase
of clean air vehicles.

Motor Vehicles’ Decal Application Fee Is Not Sufficient to Cover the Decal
Program’s Administrative Costs
Although state law requires Motor Vehicles to collect a decal fee sufficient to
reimburse the department for its actual costs incurred to operate the decal
program, Motor Vehicles does not track whether the application fees are
sufficient to recover the amount it spends to administer the decal program.
Since early 2002 Motor Vehicles has charged applicants a one‑time fee of
$8 to obtain a set of clean air vehicle decals. However, according to our

$15 per decal—rather than $8—if it cover its costs for administering the decal program. According to the chief

the decal program. funded through the Motor Vehicle Account. In addition, he stated that
this account receives fee revenue from many of Motor Vehicles’ programs,
including the decal program. Until Motor Vehicles performs a full cost
analysis to update the application fee, revenue from other programs
contributing to the Motor Vehicle Account will continue to support the
decal program.
Motor Vehicles has not updated the decal fee since the inception of the
white decal program in 2000. Motor Vehicles’ cost accounting unit manager
indicated that the department likely performed a cost analysis in 1999 to
establish the white decal program’s $8 fee, but it does not have a record of
that analysis. In December 2003 Motor Vehicles performed a cost analysis
when legislation was first proposed to establish the now‑discontinued
yellow decal program for hybrid cars. At that time, Motor Vehicles
estimated that each decal would cost the department $8.63 to process.
According to the budget chief, the cost per decal was close enough to the
existing fee of $8 that Motor Vehicles did not seek to increase it. However,
he acknowledges that Motor Vehicles has not performed an analysis of its
actual costs to administer the decal program since that time.
Because no cost analysis of the decal program has occurred since 2003,
Motor Vehicles does not know whether the decal application fee of $8 is
sufficient to cover program costs. The budget chief explained that Motor
Vehicles has not performed a full cost evaluation for the decal program
primarily because the program was always intended to be short term, and
because a number of times the program end dates in state and federal law
were extended, often with short notice. He stated that doing a full cost
evaluation would be expensive relative to the fees received, and changing
the fee would require going through the public rule‑making process, which
could take about a year and might not take effect until after the program
expires.
Although Motor Vehicles indicated that performing a full cost analysis
would be expensive, it already collects data for many of the elements it needs
to perform such an evaluation. For example, Motor Vehicles completes
weekly reports indicating how much time staff spend working on the decal
program and keeps updated information on the cost of printed items,

such as envelopes, decal registration cards, and the decals themselves. Because the decal program

Vehicles’ program costs.
Using costs the program incurred during fiscal year 2013–14, we
determined that to fully cover program costs, Motor Vehicles should
increase the decal fee to $15 from its current level of $8. Furthermore,
our review found that it cost Motor Vehicles, the only department
that reports costs for the decal program, approximately $711,000 to
administer the decal program in fiscal year 2013–14 and collected fees
of $384,000. We estimate that if it had raised the application fee to
$15, Motor Vehicles would have collected an additional $336,000 in fees
for fiscal year 2013–14. Motor Vehicles agrees with our assessment that in
fiscal year 2013–14 the cost per decal was $15, and its budget chief stated
that Motor Vehicles intends to perform a full cost analysis of the decal
program by January 2016 and that it will update the decal fee accordingly.
Caltrans’ Monitoring Indicates That Congestion in Carpool Lanes Is Increasing,
but Vehicles With Decals Do Not Appear to Be a Significant Factor
In examining speeds in California’s carpool lanes, Caltrans determined
that although carpool lanes have become increasingly congested during
recent years, vehicles with decals do not play a major role in lane
slowdowns. Although state law does not require Caltrans to review the
success of the decal program, Caltrans is required to review the vehicle
speeds of carpool lanes. Federal law gives Caltrans the authority to allow
clean air vehicles to use carpool lanes provided that the lanes maintain
minimum average operating speeds. It defines the minimum average
operating speed as 45 miles per hour in carpool lanes on highways that
have a speed limit of 50 miles per hour or greater.
To meet the federal 45‑mile‑per‑hour standard for carpool lanes, Caltrans
must monitor and assess the performance of carpool lanes and report its
findings to the federal government detailing the impacts of low‑emission
vehicles on those lanes. If lane speeds fall below the minimum average
operating speed of 45 miles per hour 90 percent of the time over a
consecutive 180‑day period, the federal government requires that Caltrans
take steps to improve the lane speeds. These steps can include increasing
the minimum number of occupants per vehicle or discontinuing clean
air vehicles’ use of carpool lanes. Failure to meet this standard can
result in sanctions from the federal government, which may include the
withholding of federal payments.
30 California State Auditor Report 2014-124
February 2015
In its July 2014 report on the condition of the State’s carpool lanes,
Caltrans found that 759, or 57 percent, of 1,339 carpool lane miles fell
below the minimum speed standards from July to December 2012. The
report states that the factors causing these speed reductions include,
among other things, recurring congestion, vehicles attempting to enter
or exit carpool lanes, inclement weather, and other traffic disruptions.
The report compared these data with observations that Caltrans made
from July 2011 to December 2011 and found that the percentage of
carpool lanes operating below minimum average speeds increased by
16 percent. In fact, Caltrans noted that this percentage increased even
after the State eliminated carpool lane access for 85,000 vehicles when
the yellow decal program ended in June 2011. Therefore, Caltrans’
report does not conclude that the decal program is a significant cause
of congestion in carpool lanes. Further, in its July 2014 action plan to
improve the average speeds in carpool lanes, Caltrans states that it is not
considering prohibiting vehicles with decals from using carpool lanes,
because Caltrans concludes that they make up a very low percentage
of the total number of vehicles in carpool lanes. Instead, the action
plan proposes a combination of short‑term and long‑term strategies
to improve average lane speeds, such as increasing Highway Patrol
enforcement, improving response times for vehicles that become
disabled in carpool lanes, and improving infrastructure on corridors
with carpool lanes.
In addition to its annual report to the federal government on the
performance of the State’s carpool lanes, Caltrans collects data on the
total number of vehicles and the vehicle occupancy counts for carpool
lanes, including the number of vehicles with decals. Caltrans’ data
indicate that between 2006 and 2011, the number of vehicles with decals
was relatively constant and did not surpass 7 percent of the total carpool
lane volume for any of the six Caltrans districts that had carpool lanes.
Motor Vehicles Collects the Geographic Locations of Decal Recipients, but Air
Resources Board has not Assessed the Decal Program’s Impact on Air Quality

shows. Specifically, approximately nine out of every thousand residents in
Santa Clara County possess clean air vehicle decals, which is almost three
more people per thousand than the next highest county, Marin. Table 7
also illustrates that the top five counties with the highest total number
of decals issued—Los Angeles, Santa Clara, Orange, Alameda, and
San Diego—possess nearly 70 percent of the existing carpool lane miles
California State Auditor Report 2014-124 31
February 2015
in the State. Further, Figure 2 on page 33 shows that these five counties
reside in air basins that have failed to meet the U.S. Environmental
Protection Agency’s national 8‑hour ozone standard in 2011. This standard
establishes the concentration above which ozone is known to cause
adverse health effects to sensitive groups, such as children and the elderly.
Ozone is a colorless gas and is the chief component of urban smog. It is
not directly emitted as a pollutant, but it is formed in the atmosphere
when hydrocarbon and oxides of nitrogen emissions—which vehicles
emit—react in the presence of sunlight. According to the Air Resources
Board, because of the reaction time involved for ozone to form, peak
ozone concentrations often occur far downward of the oxides of nitrogen
emissions. In other words, ozone concentrations can occur in areas other
than where the oxides of nitrogen are emitted. It is important to note that
ozone is one of a series of seven pollutants adopted by both the federal
government and California to measure air quality; therefore, ozone by
itself does not provide a complete picture of the air quality in California.

Note: We excluded 1,185 decals from the table because Motor Vehicles either did not record a county code or recorded an invalid county code.
In fact, according to the Air Resources Board’s 2013 report, The
California Almanac of Emissions and Air Quality (air quality almanac),
nine of the State’s 15 air basins failed to meet the same federal ozone
air quality standard in 2011. As Figure 2 shows, the five air basins with
the highest concentration of ozone pollution are the South Coast,
San Joaquin Valley, Mojave Desert, Sacramento Valley, and Salton Sea
air basins. Notably, there are few or no carpool lanes in the San Joaquin
Valley air basin and very few decals issued to counties within this air
basin as well. Therefore, the decal program provides minimal incentive
for residents of these counties to purchase clean air vehicles. The Air
Resources Board points out that carpool lanes are one of a number of
strategies that can be used to improve air quality in regions with high
vehicle emissions and traffic congestion. Figure 2 also shows the counties
having the highest oxides of nitrogen emissions produced by on‑road
motor vehicles in 2012.
Further, the air quality almanac explains that other factors besides
emissions, such as weather and terrain, influence air quality. For example,
hot, sunny summer days typically lead to high ozone, and the mountains
that form a barrier to the east of the Los Angeles area tend to retain air
and limit the dispersion of pollutants, including ozone. Although the
decal program might have some effect on air quality, the Air Resources
Board indicates that it has not produced an air‑basin pollution study to
demonstrate the decal program’s contribution to improved air quality.
The Air Resources Board further explained that such a study would be
costly to administer, and any results would be difficult to correlate to the
decal program because the State is simultaneously undertaking actions
in addition to the decal program to reduce air pollution and minimize
greenhouse gases in California. Until the Air Resources Board evaluates
the potential connection between the decal program and the State’s air
quality, the full impact of the program will be unknown.

Both the Solar Initiative and the Decal Program Tend to Serve
Californians With Higher Incomes
While participation in both the solar initiative and the decal program
has increased over time, both programs have served mostly a narrow
demographic of Californians. In requesting this audit, the Joint
Legislative Audit Committee asked us to determine whether the
incentives received through both programs were used equally across
the State in terms of demographic characteristics, such as age, race,
gender, and income level. Specifically, the available demographic
data show that participants in the solar initiative tend to be older,
wealthier, and have received more education than most California
homeowners. Similarly, most decal program participants tend to have
a higher income than the average Californian.
Although the commission is not required to collect demographic
information from solar initiative participants, the 2014 consultant’s
study discussed earlier, which surveyed a random sample of 72 out
of 86,848 residential participants in the General Market Program
from 2007 through 2012, determined that the participants were
older, wealthier, and received more education than the population
of California homeowners as a whole. As Figure 3 illustrates, most
participants are at least 55 years old, have a college education, and
live in two‑person households with annual household incomes
of $100,000 or more. Furthermore, the 2014 consultant’s study
concluded that the high percentage of participants who live in
two‑person households indicates that many participants are parents
of grown children or that many have dual incomes but no children.
This survey did not assess the race or ethnicity of residential
participants and did not analyze the demographics of nonresidential
participants or participants of the single‑family, multifamily, and
thermal programs. Overall, the consultant’s study concluded that the
residential participants’ diversity remained unchanged from 2007
Despite these demographic results, through 2012. Despite these demographic results, as described earlier,

In addition to conducting the demographic survey, the consultant
randomly surveyed 300 single‑family residential customers across all
income levels who do not own solar energy systems and determined
that the high cost of a solar energy system was the main reason why
residential customers had not installed them. The 2014 consultant’s
study found that almost half of the respondents—43 percent—wanted
to see cheaper prices before they would purchase a solar energy system.
As the Introduction discusses and as Table 2 on page 8 shows, a typical
5‑kilowatt solar energy system installed at a residential property under
the solar initiative in 2014 costs about $17,045 after discounting for
both the solar initiative incentive and federal tax credit. Even if the

than do households with average or low incomes.
Further, this consultant conducted in‑depth interviews with solar
finance companies, installers, manufacturers, and other market
participants that possess intimate knowledge of the solar market, and
the study concluded that marketing to less creditworthy customers
did expand the overall adoption of solar energy systems, but that
this expansion is only a limited form of diversification. When asked
why the demographics have remained the same from 2007 to 2012,
these interview respondents stated that solar finance companies
and installation contractors tended not to change the target of their
marketing efforts during this period except to offer financing for solar
projects to customers with low credit scores. Specifically, respondents
at solar finance companies stated that they have found it necessary
to diversify their target customer profiles slowly in order to gain the
confidence of investors.
In regard to the decal program, none of the state agencies administering
the decal program obtain demographic information on decal recipients
and, according to the Air Resources Board and Motor Vehicles, this
is not within the scope of their respective roles under state law. As
a result, we were unable to determine whether the decal program
was used equally across the State in terms of age, race, gender, and
income level.
Although the administering state agencies do not obtain demographics,
a recent consumer survey for a related clean air vehicle incentive
program provides certain demographic information with respect
to the decal program. On behalf of the Air Resources Board, the
center administers state rebates for purchasers of clean air vehicles.
Specifically, the center provides individuals, nonprofits, government
entities, and business owners with rebates of up to $5,000 for the

From October 2013 through July 2014, the center conducted a survey
of rebate recipients to provide market data on various demographic
and behavioral topics, including age, gender, and income. However,
the survey results do not fully represent the demographics of decal
recipients. For example, the center noted that although 90 percent of
the 10,900 respondents intend to obtain decals, 10 percent have no
plans to obtain a decal.
In addition, the center offers the survey only to clean air vehicle
owners who received a rebate; however, not every clean air
vehicle owner applies for a rebate, nor is every clean air vehicle
eligible for a rebate. As a result, the survey results do not represent
all recipients of decals. Nonetheless, because most
survey respondents intend to obtain decals, the
survey results indicate who is purchasing clean air

Recommendations
The Solar Initiative
To make certain that the research program contributes to the goals
of the solar initiative, the commission should conduct a program
evaluation before the remaining grant projects are completed.
Because the thermal program has not been successful in meeting
the goals outlined in state law, the Legislature should consider
whether it wants to continue authorizing the collection of
ratepayers’ money to fund the program.
38 California State Auditor Report 2014-124
February 2015
To show how air pollution emissions reductions related to the solar
initiative benefit the State, the commission should include in future
reports the measurable benefits of those reductions.
The Decal Program
To learn whether the decal program helps to reduce the State’s air
pollution, the Legislature should require the Air Resources Board to
research whether there is a relationship between decal usage and a
change in the State’s air quality.
To ensure that the decal fee is sufficient to reimburse program
costs, Motor Vehicles should periodically perform a full cost
analysis of the decal program and update the fee accordingly.
We conducted this audit under the authority vested in the California State Auditor by Section 8543
et seq. of the California Government Code and according to generally accepted government auditing
standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate
evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives
specified in the scope section of the report. We believe that the evidence obtained provides a
reasonable basis for our findings and conclusions based on our audit objectives.

Comments
CALIFORNIA STATE AUDITOR’S COMMENTS ON
THE RESPONSE FROM THE CALIFORNIA PUBLIC
UTILITIES COMMISSION
To provide clarity and perspective, we are commenting on the
California Public Utilities Commission’s (commission) response to
our audit. The numbers below correspond to the numbers we have
placed in the margin of the commission’s response.
1
Although we are pleased that the commission still intends
to evaluate the Research, Development, Deployment and
Demonstration Program (research program), the commission
has not addressed our concern regarding its delay in doing so.
As we describe on page 22 of the report, the commission’s order
that implemented the research program in 2007 stated that the
research program would be evaluated every three years. Also on
page 22, the commission acknowledges that a program evaluator
was never hired because it was waiting until a sizable portion
of the grants were completed. As of January 2015—seven years
into the program—the commission still had not solicited requests
for proposals or taken any other steps toward securing a program
evaluator, although by that time the research program had awarded
all of its funds. Moreover, in contrast to the commission’s response,
we did not state that “now that the grant recipients for the final
solicitation have been announced and all the projects have been
launched, it is an optimal time to conduct the program evaluation.”
Rather, we stated on page 23 that the commission should have
ensured that the evaluations were being done on an ongoing basis,
as originally planned.
2
We agree with the commission that determining how—or even
if—the pollution emission reductions linked to the California Solar
Initiative (solar initiative) benefit the State will require specialized
expertise. Nevertheless, Senate Bill 1 (Chapter 132, Statutes of 2006)
indicates that the solar initiative should have pollution reduction
benefits. As noted in our report, the commission has used outside
consultants in the past for specialized expertise and analysis.
Although the commission asserts that it needs the assistance of the
California Air Resources Board (Air Resources Board) to translate
emission reductions into benefit calculations, the cooperation
of the Air Resources Board should not be an impediment to the
commission’s effort to determine the pollution reduction benefits of
the solar initiative.
