The Golden State’s Building Standards Commission has approved legislation that requires any California home built in 2020 or later be solar powered. “Energy officials estimated the provisions will add $10,000 to the cost of building a single-family home, about $8,400 from adding solar and about $1,500 for making homes more energy-efficient. But those costs would be offset by lower utility bills over the 30-year lifespan of the solar panels.” “These provisions really are historic and will be a beacon of light for the rest of the country,” said Kent Sasaki, a structural engineer and one of six commissioners voting for the new energy code. “(It’s) the beginning of substantial improvement in how we produce energy and reduce the consumption of fossil fuels.” The new provisions are expected to dramatically boost the number of rooftop solar panels in the Golden State. Last year, builders took out permits for more than 115,000 new homes — almost half of them for single-family homes.
