A city in southern California this week passed a zoning regulation that requires developers to install solar power systems on every new house they build. Beginning next year, all new homes built on lots at least
7,000 square feet in size in Lancaster, Calif. will be required to produce at least one kilowatt of solar electricity. Developers also have the option of purchasing solar energy credits from other developments within the city limits. The new zoning rules are the latest initiative in Mayor Rex Parris’s quest to make Lancaster, which has a population of 150,000 and abundant sunshine, the “solar capital of the universe.” Since 2008, the city has also introduced an initiative to attract utility-scale solar developers to the city, proposed a transmission project to deliver solar-generated power to other communities, and created a solar financing program for homeowners, businesses, and nonprofits.
