On May 6, the city council of Sebastopol, CA voted to approve a measure requiring all new residential and commercial buildings to be fitted with solar panels. The new buildings will have to have 75 percent of their annual electric load offset by the solar panels, or meet a threshold of 2 watts of power per square foot of insulated building area. Sebastopol is the second California city to enact a solar power requirement, following a move by Lancaster, CA earlier this year.
