To achieve clean-energy goals, California took a giant step and has become the first state to require all new homes to have solar power.
California law requires at least 50 per cent of the state’s electricity to come from non-carbon-producing sources by 2030. Solar power provides almost 16 per cent of the state’s electricity, and the industry employs more than 86,000 workers.
Under the new requirements, builders must take one of two steps: make individual homes available with solar panels, or build a shared solar-power system serving a group of homes. The requirement is expected to add $8,000 to $12,000 to the cost of a home.
California averages about 80,000 new homes a year, with about 15,000 currently including solar installations. Over all, at the current rate of home building, the new requirement will increase the annual number of rooftop solar installations by 44 per cent.
