“New data shared by the Californian government shows that the state has supplied 100 percent of its electricity demand with clean energy sources for an average of seven hours a day so far this year.
More than nine out of 10 days in 2025 saw the state’s power being run on completely clean energy sources for an extended period of time in the day—representing a 750 percent increase in clean energy days since 2022.”
…
“The data signifies a major milestone in California’s clean energy deliveries, marking it as the largest economy in the world to achieve this level of clean energy, according to the state government. The success of the state, the world’s fourth largest economy, also holds weight for national and international energy policy.
Clean energy includes renewable resources—such as wind, solar, geothermal and biomass—and large hydroelectric power and nuclear energy. California’s goal is to have 100 percent of its retail electricity sales and state agency loads supplied with clean energy by 2045.”
Launched in 2017 by the governors of Washington, New York, and California to help fill the void left by the U.S. federal government’s withdrawal from the Paris Agreement, the Alliance has grown to include 24 governors from across the U.S. representing approximately 60 percent of the U.S. economy and 55 percent of the U.S. population. Governors in the Alliance have pledged to collectively reduce net greenhouse gas emissions by at least 26-28 percent by 2025, 50-52 percent by 2030, and 61-66 percent by 2035, all below 2005 levels, and collectively achieve overall net-zero greenhouse gas emissions as soon as practicable, and no later than 2050.
The Alliance’s states and territories continue to advance innovative and impactful climate solutions to grow the economy, create jobs, and protect public health, and have a long record of action and results. In fact, the latest data shows that as of 2023, the Alliance has reduced its collective net greenhouse gas emissions by 24 percent below 2005 levels, while increasing collective GDP by 34 percent, and is on track to meet its near-term climate goal of reducing collective greenhouse gas emissions 26 percent below 2005 levels by 2025.
