California has ambitious efforts underway to decarbonize our electric grid by 2045. The choices we make today will help determine how affordably, equitably and reliably we can get there.
Renewables are an important piece of the puzzle, but we will also need something else. Renewable energy supplies can drop up to 60% between summer and winter months, due to cloudier skies and less-powerful winds. Short duration storage batteries can complement renewable generation production on a day-to-day basis, but they cannot pull the state through several weeks of reduced supply.
