Have you heard about California PACE energy program? PACE stands for Property-Assessed Clean Energy, and this program serves as a mechanism for financing energy-efficient and renewable energy improvements on private properties.
When authorized by state law—as it is now in California—the PACE program allows local and state governments or other inter-jurisdictional authorities to fund the up-front cost of energy improvements on both commercial and residential properties, which can then be paid back over time by property owners.
