California has hit a new milestone in clean energy, as the state continues to move away from fossil fuels in its decades-long effort to continue to reduce air pollution and greenhouse gas emissions.
In 2021, 37% of the state’s electricity was generated by renewable sources like solar and wind — up from 34% the year before, and double the 16% total in 2012, according to new numbers released Thursday by the California Energy Commission.
More broadly, when nuclear power and hydroelectricity from large dams are included, 59% of California’s electricity now comes from carbon-free sources. The state has a goal of 90% by 2035 and 100% by 2045.
Highlighting the trend, Gov. Gavin Newsom appeared in Richmond on Thursday to cheer the announcement that Moxion Power, a company founded three years ago which now has 250 employees working to build zero-emission electric batteries to replace diesel generators, will open a new manufacturing facility at the site of the former Richmond Ford Point Assembly Plant on Harbour Way.
During World War II, the plant built Jeeps, armored personal carriers and other vehicles for the Pacific Theater before closing in the 1950s. The new facory will create about 800 new jobs, the company said.
“The future happens here first,” Newsom said. “We are America’s coming attraction. It is our responsibility to lead. And we do. No other state has more scientists, engineers, more researchers, more Nobel laureates, more patents emanating out of one state than the state of California.”
Over the past 20 years, California has been steadily increasing the amount of solar and wind power it requires utilities to purchase to reduce smog and greenhouse gas emissions.
But the greener power grid has come at a cost: Less reliability.
During severe heat waves, millions of Californians turn on their air conditioners, spiking demand for electricity. At night when the sun begins to set, solar farms go off line, even as demand remains sky high.
That’s what happened last September, when all-time heat records tumbled across California, including 118 degrees in Calistoga, and the day before 116 in Livermore and 109 in San Jose.
Blackouts were narrowly averted, but only after Newsom urged Californians to curb electricity use between 4 p.m. and 9 p.m., and relaxed air pollution rules to allow temporary natural gas-fired “peaker” plants and other generators to fire up.
To help improve reliability, state regulators have ordered utilities to put in place huge battery systems to store solar power on sunny days, then let it out on the grid at night. In 2019, California had 250 megawatts of battery storage. It has 5,000 megawatts now — roughly the same as 10 natural-gas fired power plants.
Newsom also signed a bill in September, over the objections of some activists, to keep PG&E’s Diablo Canyon, the state’s only nuclear power plant, open for another five years after its 2025 planned closure date.
Meanwhile, the drenching storms that California received this winter filled most of the state’s largest reservoirs. The water is expected to deliver a banner year for hydroelectric power.
Those factors caused state energy officials this week to announce they do not expect to have the kind of tight issues between supply and demand this summer that have raised the risk of blackouts in recent years. A major wildfire that took out large transmission lines could change that, they said, but overall, conditions are better than in recent years.
“The summer outlook is looking much better than we anticipated,” said Siva Gunda, an engineer who sits on the board of the California Energy Commission.
Newsom on Thursday also released a 20-page document laying out the state’s goals and challenges as it moves toward 100% renewable energy.
The report, “Building the Electricity Grid of the Future: California’s Clean Energy Transition Plan,” notes the state has already hit many of its early goals for electric vehicles and renewable energy. But it notes that to have 100% carbon-free electricity by 2045 “we need to build more clean energy, faster.”
Over the next 20 years, the report calls for expanding transmission lines, building 25,000 megawatts of offshore wind farms, making heat pumps widespread in homes, embracing new technology that allows homes to be run by plugging into electric car batteries, building more battery storage for the grid, and changing electricity bills by providing incentives for residents to run appliances like dishwashers, dryers and washing machines during non-peak times of the day.
Newsom said that the state must do more to cut red tape so solar farms, wind farms, and other green energy projects can be built more quickly. Last week, he introduced 11 bills in the Legislature that would curb the California Environmental Quality Act, a powerful law that requires environmental studies of major projects.
The law, which was passed 50 years ago, is often the basis of lawsuits by opponents of projects, including neighbors, environmental groups and labor unions. Prior governors, including Arnold Schwarzenegger and Jerry Brown, have attempted reforms, without much success in Sacramento.
“As it relates to process, enough,” said Newsom, whose reforms to CEQA would require lawsuits to be resolved within 270 days not only for renewable energy projects, but for major water projects like new reservoirs. “We need to build. We need to get things done. We are running against time.”
“We don’t have time to hold hands and talk about the way the world should be,” he said, citing the increased heat waves, forest fires and other disruptions from climate change. “We’ve got to go.”
