The California Assembly took aggressive steps to limit greenhouse gas emissions as legislators voted to require that 100 percent of the state’s electricity come from carbon-free sources by 2045. Senate Bill 100 authored by State Senator Kevin de León, gradually raises California’s renewable energy target to 60 percent by 2030 with interim targets, and gives the state until 2045 to generate the rest of its electricity from carbon free sources. The bill will need to be approved by the state senate and Governor Jerry Brown. Brown has already set out ambitious goals to expand renewables and the use of electric cars.
The only other state in the country to require all of its energy to come from clean sources is Hawaii. California’s existing large hydropower or nuclear power plants, though they produce carbon-free electricity, do not qualify for the state’s renewable portfolio standard laws. New technologies are expected to arise in the years to come. California ridding itself entirely of carbon-intensive energy has been a politically vexed proposition for the past two years. “This is a pivotal moment for California, for the country, and the world,” said Michael Brune, the executive director of the Sierra Club.
