Brown also signed an executive order setting a target of 2045 to achieve carbon neutrality.

Brown hailed the move as another example of the state's global leadership on environmental initiatives as the Trump administration backs away from such policies.

"California is committed to doing whatever is necessary to meet the existential threat of climate change", the Governor declared.

The clean energy bill, known as SB 100, passed the legislature last month.

As of 2017, the past year for which complete data is available, the state got 44 percent of its electricity from renewable sources, including 15 percent from large hydroelectric projects, just over 10 percent from solar, and 9 percent from wind power.

Under the newly signed bill, the state's RPS will be updated to require 50 percent renewables by 2026, increasing to 60 percent renewables by 2030. Kevin de Leon, right, holds a copy of the bill, Monday, Sept. 10, 2018, in Sacramento, Calif. SB100 sets a goal of phasing out all fossil fuels from the state's electricity sector by 2045. Nevertheless, pursuing 100% renewable energy has never been more important, as we get closer to entering a time that scientists say will be the point of no return from irreversible climate damage.

State utilities and energy producers are now being pushed to make up the difference. The policies - including electric vehicle incentives, a "cap and trade" program to put a price on carbon emissions, and renewable energy mandates - have helped the state reduce emissions to the same level as 1990.

"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. Utilities rely on natural gas plants to meet demand when renewables fall short, particularly in the early evening when the sun sets and people turn on their air conditioners as they get home from work.

Energy Storage North America (ESNA), the most influential gathering of policy, technology and market leaders in energy storage, applauds Governor Jerry Brown and the California State Legislature for passing landmark Senate Bill (SB) 100, which sets the largest-scale zero-emission electricity targets ever established for a USA state.

The executive order signed by Brown directs the state to achieve carbon neutrality by 2045 and net negative greenhouse gas emissions after that.

When the law takes effect in January, California and Hawaii will be the only two states to have pledged to eliminate fossil fuels as a source of electricity by that date. Assemblywoman Lorena Gonzalez Fletcher, D-San Diego, left, who carried the bill in the Assembly, watches.
