May 21 update: Stanford University professor of civil and environmental engineering Mark Z. Jacobson continues to track California''s renewables performance – and it''s still exciting. In an update today on Twitter (X), Jacobson reports that California has now exceeded 100% of energy demand with renewables over a record 45 days straight, and 69 out of 75:
April 15: Stanford University professor of civil and environmental engineering Mark Z. Jacobson has been tracking California''s renewables performance, and he shares his findings on Twitter (X) when the state breaks records. Yesterday he posted:
Jacobson notes that supply exceeds demand for "0.25-6 h per day," and that''s an important fact. The continuity lies not in renewables running the grid for the entire day but in the fact that it''s happening on a consistent daily basis, which has never been achieved before.
And what makes it even better is that California has the largest grid-connected battery storage facility in the world (came online in January ), meaning those batteries were filling up with excess energy from the sun all afternoon today and are now deploying as we speak to offset a good chunk of the methane gas generation that California still uses overnight.
On April 2, the California Independent System Operator (ISO) recommended 26 new transmission projects worth $6.1 billion, with a big number being devoted to offshore wind.
This is great news. We have to temper our enthusiasm a tad given that the above average precipitation during the last two winters has boosted hydro production. Solar and Wind need to keep advancing so CA can weather the next drought which is sure to happen.
California passed a law that commits to achieving 100% net zero electricity by 2045. Will it beat that goal by a decade? We hope so. It''s going to be exciting to watch.

Something spectacular is happening in the Golden State. California—the fifth-largest economy in the world—has experienced a record-breaking string of days in which the combined generation of wind, geothermal, hydroelectric and solar electricity has exceeded demand on the main electricity grid for anywhere from 15 minutes to 9.25 hours per day. These clean, renewable electricity sources are collectively known as wind-water-solar (WWS) sources.
As California invests billions in energy infrastructure, the clean energy supply continues to increase as the state progresses toward the goal of 100 percent zero-carbon electricity sales by 2045.
SACRAMENTO— Non-fossil-fuel sources now make up 61 percent of retail electricity sales in California thanks to historic investment that has led to an extraordinary pace of development in new clean energy generation,according to the latest data compiled by the California Energy Commission (CEC).Sources eligible under theRenewables Portfolio Standard such as solar and wind make up 39 percent of the state power mix, an increase of 2 percent compared to the previous year, while large hydro and nuclear made up a combined 22 percent.
"Nearly every week, new clean energy projects are being added to the grid, moving us closer and closer to our goal of a clean, affordable and reliable energy system in California," saidCECChair David Hochschild.
Ahead of National Infrastructure Week, the CEC and California Public Utilities Commission (CPUC) are highlighting the state''s progress to build the clean energy grid of the future.
"I want to congratulate the many agencies, groups and organizations whose work has led to the success of California''s clean energy efforts," said CECVice Chair Siva Gunda. "Your tireless work is helping us march forward toward a more sustainable future."
WHY IT MATTERS:California is in the middle of the biggest transformation of its power grid in a century. The continued rise in renewables and decline in fossil fuel use comes as the state experiences an unprecedented barrage of climate impacts, from heat waves to drought and wildfires.
