Residential Solar Installation Costs In America’s Battleground State

By Roy L Hales

California’s energy sector is hurtling towards the point of decision. Despite its reputation as a green leader, this is the #3 American state for crude oil production. In the past few years, solar energy production has grown to supply around 16% of the state’s electricity.1   A significant portion (5.7%) is supplied by rooftop solar. Though there is considerable push back from Big Oil, the California legislation’s goal of 50% renewable electricity by 2030 seems attainable.

As their name suggests, San Diego Gas & Electric’s #1 energy source is natural gas. They obtained 54% of their electricity from gas burning plants in 2015. Yet they also operate in a state which intends to produce 33% of its’ electricity from renewables by 2020. SDG&E has already exceeded that target, using renewables like solar,  wind and hydro to provide 35% of their supply. Now, in compliance with California Public Utilities Commission (CPUC) guidelines, SDG&E unveiled the World’s largest lithium ion energy storage facility.
