The California Energy Commission has approved a proposal that requires all new houses in the state to install rooftop solar panels, a “historic” move that’s likely to bring huge economic and environmental benefits.

The mandate, which comes into effect in 2020, offers adequate flexibility in the regulations, for example builders can power multiple homes with a community solar system instead of separate units for each one of them, writes Los Angeles Times.

Critics warn that the new rule will add about $9,500 to the cost of a new house, further worsening California’s affordable housing crisis, reports CNBC.
