California demonstrates renewable energy’s reliability through recent advancements, according to a new study.
The research, published in the prominent peer-reviewed journal Renewable Energy, reveals that for 98 out of 116 days from late winter to early summer last year, renewable energy sources met 100% of the state’s electricity demand for up to 10 hours daily.
Lead author Mark Z. Jacobson of Stanford University stated, “This study really finds that we can keep the grid stable with more and more renewables.” He added that major renewable sources are now more cost-effective than fossil fuels.
The study compared data from 2023 and 2024, showing significant increases in solar and wind output. Battery capacity in California doubled during this period, now equivalent to the power produced by over four nuclear plants. This expansion helped reduce fossil fuel consumption for electricity by 40%.
