For example, last month Southern California Edison (SCE) submitted its Integrated Resource Plan (IRP) that highlighted the significant role of energy storage in achieving the state's electricity sector greenhouse gas (GHG) emission reduction goals by 2030.
"Brown really launched the modern renewable energy industry when he was governor the first time", said Jim Williams, a professor of Energy Systems Management at the University of San Francisco and author of a seminal 2012 study that mapped the decarbonization of California's economy by mid-century.
California Governor Jerry Brown signed legislation that would require all of the state's electricity to come from carbon-free sources by 2045, marking the biggest step yet in his fight against global warming.
Ever the state to lead the charge towards a more sustainable future, California has set an ambitious goal to rely entirely on renewable electricity by 2045.
"There's no understating the importance of this measure", Brown said, moments before signing the two actions. He also issued an executive order calling for statewide carbon neutrality - meaning California "removes as much carbon dioxide from the atmosphere as it emits" - by the same year.
Brown's signing came days before he hosts a gathering of local, worldwide and business leaders in San Francisco to highlight the urgency of addressing climate change.
Hugo Lloris fined £50,000 after admitting drink-driving
The court heard that the goalkeeper had been out at a restaurant that evening, where he had been bought drinks by other customers. Lloris was charged with a single count of drink driving and appeared at Westminster Magistrates Court on Wednesday morning.
Opponents - including the state's investor-owned utilities run by PG&E Corp., Edison International and Sempra Energy - raised concerns that the requirement would increase electricity costs. "We believe customers must be protected from unreasonable rate and bill impacts".
"It will not be easy", Brown tweeted after signing Senate Bill 100 and a related executive order.
Jerry Brown says he hopes a law he's signed moving California toward eliminating fossil fuels for electricity will serve as a model for other state and national governments. It is more of a goal than a mandate.
Major cities will likely announce greenhouse gas emissions trending downward, and governors will unveil partnerships supporting indigenous efforts to sustainably manage tropical, carbon-dense forests. The state now gets about 44 percent of its power from renewables and hydropower.
Renewable energy experts have looked to batteries that can store solar energy generated in the afternoon as one solution, but the technology is not ready for wide-scale deployment.
In a poll in July by the Public Policy Institute of California, a non-partisan research organization, 67 percent of likely voters said they favored the 100 percent clean energy measure, and 21 percent opposed it. Kevin de León, a Los Angeles Democrat who carried SB 100, said. Another 9 percent comes from nuclear plants.
