A groundbreaking study has debunked the myth that renewable energy can’t sustain a reliable power grid. From late winter to early summer 2024, California’s wind, solar, and battery systems supplied 100% of the state’s electricity needs for up to 10 hours on 98 of 116 days—without a single blackout. Compared to the previous year, solar output increased by 31%, wind by 8%, and battery capacity more than doubled, allowing excess solar energy to be stored for nighttime use. This shift helped cut fossil fuel consumption by 40%, demonstrating that a clean energy grid is both feasible and effective.
While California’s electricity prices remain high due to infrastructure costs, the study highlights that renewables themselves are more cost-effective than fossil fuels. Battery storage is playing a key role in stabilizing demand, ensuring power is available even during peak evening hours. As California continues to lead the way in renewable energy, its success offers a blueprint for a sustainable and resilient future.
