Recent data from the California Energy Commission has revealed that California achieved a new renewable energy milestone in 2023: drawing 67% of its retail electricity supply from wind, hydropower, solar, and other renewable sources, up from 61% in 2022. The previous record was 64% renewable energy in 2019, just a year after former California Governor Jerry Brown signed a state law designed to reduce greenhouse gas emissions and air pollution.
Under the 2018 emissions reduction measure, California is set to achieve 100% carbon-free and renewable electricity by the year 2045, with wind, biomass, solar, nuclear, and large hydropower providing the bulk of the state’s green electricity. News of California’s new green energy milestone comes as the state’s renewable energy sector faces several notable challenges.
For instance, the Trump administration recently passed a bill that reduced or eliminated most of the federal grants, tax breaks, and incentives that the Biden administration had set up to help states, homeowners, and private companies expand clean energy capacity and electric vehicle adoption.
In a statement released on Monday, Governor Gavin Newsom said that although the GOP-led federal administration is turning away from innovation, California will continue focusing its efforts on adopting clean energy. He noted that as the fourth-largest economy in the world, California reaching a milestone where two-thirds of its energy comes from clean sources is an unprecedented achievement among economies of its size. One of the main drivers behind California’s aggressive adoption of clean energy has been its expanding energy storage capacity.
Since renewable energy is intermittent in nature, meaning green energy sources require specific conditions to operate at peak efficiency, renewables work best when paired with energy storage. For instance, a solar project with on-site battery storage can save excess energy generated during the day when production is high but consumption is low, and release it into the grid at night when demand spikes but solar output is down.
Energy storage makes renewables much more reliable and allows green energy plants to supply electricity regardless of time or weather conditions.
By deploying a massive network of battery storage facilities over the past half decade, California has significantly boosted the reliability of its clean energy sources and made renewables a cornerstone of its energy mix.
The state’s battery storage capacity increased from 1,474 MW in 2020 to 15,763 MW in 2025, according to the California Energy Commission. Unfortunately, there is growing grassroots opposition to battery storage sites after a major battery plant in Moss Landing, Monterey County raised public safety concerns.
Despite such challenges, California’s progress proves that strong policy, investment, and infrastructure can drive green energy success. As the federal government steps away from supporting clean energy, states like California are showing what’s possible, but without national backing, the U.S. risks falling behind global leaders like China and the European Union in the transition to a sustainable energy future.
As California’s example is replicated in more states, related eco-friendly technologies, such as EVs made by entities like Mullen Automotive Inc. (NASDAQ: MULN) could pack a bigger punch in moving towards net-zero carbon targets.
