Proposition 10 would permit $5 billion in general obligation bonds to be sold for the purpose of renewable energy, alternative fuel, and clean air emissions projects. Proposition 10 focuses on incentive programs to promote research and development of alternative fuel and renewable energy technology. The measure would also provide bond money to cities and universities for study of the technologies developed. It is expected that the state would owe approximately $9.8 billion total and would pay $325 million a year to pay back both the principal and the interest. Proposition 10 is the second measure on the November 4 ballot to focuses on alternative energy. Proposition 7 would require utilities in California to acquire 50% of their power from renewable resources by 2025.

Proposition 10

Currently, California administers different programs to promote and develop new renewable energy, alternative clean fuels and energy efficiency, and air quality projects. Many of these programs promote energy improvements by providing financial incentives in the form of loans, tax credits, grants and rebates. These programs are generally paid for through vehicle license fee revenues for the state, which are collected annually on all motor vehicles. State and local taxes provide funding as well. Some air quality programs have been paid for through the sale of general obligation bonds.

Proposition 10 would authorize the state to sell $5 billion in general obligation bonds for renewable energy, air emissions reduction, and alternative fuel programs. $3.4 billion of the funds would go to Clean Alternative Fuels Account. This money would be used for financial incentives to reduce the cost to buy or lease clean alternative fuel or high fuel economy vehicles. $1.6 billion would go the Solar, Wind, and Renewable Energy Account to fund analysis, design, development and production of renewal energy technology. The Demonstration Projects and Public Education Account along with the would be allocated $200 million, which would provide grants to eight cities for construction and use of renewable energy projects for the purposes of demonstration. Education, Training, and Out Reach Account$125 million would go to public universities and collages for training, research, development of new technology for sale in the commercial market. These funds would also be used for public outreach and education.

Several state agencies would manage the funds for different components of Proposition 10. The Air Resources Board would administer alternative-fuel research and development. The State Board of Equalization would provide alternative-fuel vehicle rebates. The California Energy Resources Conservation and Development Commission would administer renewable energy incentives as well as make the appropriate funds available to cities and and higher education institutions. The agencies would conduct internal reviews of each program including annual audits and progress reports.
