How Could a California Green Bank Help Accelerate Renewable Energy and Energy Efficiency?

This fact sheet by the Climate Policy Initiative explores how a proposed California green bank could use carbon emissions allowance revenues to accelerate renewable energy and energy efficiency. It identifies opportunities to expand financing for underserved homeowners, support small businesses and public entities, and scale up clean energy innovations, such as electric grid storage.

• A California green bank could increase access to energy efficiency and renewable energy upgrades for underserved homeowners, specifically the over 15% of homeowners who qualify for mortgages or car loans but cannot secure energy loans due to their credit scores. The bank could achieve this by providing credit enhancements to lenders, offering direct financing, or providing insurance to protect developers against homeowner repayment failures.
• The green bank could address financing barriers for small businesses and public sector entities (such as schools, municipalities, and non-profit hospitals) that cannot access tax equity financing or struggle with credit evaluations. Proposed mechanisms include acting as a direct lender, providing credit enhancements, or aggregating small projects into larger portfolios to attract low-cost private institutional investors, such as pension funds.
• To help California meet its mandate of procuring 1.3GW of electric energy storage by the end of the decade, a green bank could bear the initial financial risks of the first few storage facilities. By providing construction financing, loan guarantees, or equity contributions, the bank could generate the technical and financial performance data necessary to encourage private sector investment in subsequent projects.
• A green bank could bridge the gap between technology demonstration and commercialization—referred to as the 'valley of death'—for innovative energy technologies within California. This could be achieved through long-term debt, low-cost equity investment, or insurance products, potentially focusing on building and industrial electrification to meet 2050 goals.
• The document suggests the green bank could serve as a 'one-stop-shop' for energy financing in California, providing a portal to existing programs and facilitating common applications and standards to reduce the time and effort required for homeowners to obtain financing.
