Electricity consumption in California from April 2025 to March 2026 reveals a mix predominantly dominated by low-carbon sources, which account for more than half of the total consumption. Solar energy, both from utility and behind-the-meter installations, stands as the most significant contributor, constituting almost a third of the total consumption. In addition to solar, hydropower, nuclear power, wind, geothermal, and biofuels collectively enhance the clean energy portfolio. However, fossil energy sources still make up almost a quarter of the consumption, primarily driven by gas. There's also a notable portion of net imports, which highlights California's reliance on electricity from outside its borders.

Is Electricity Growing in California?

Despite the potential advancements in clean energy, electricity consumption per person in California decreased slightly from its historic record in 2024. The most recent numbers show a decline of 163 kWh per person, putting the consumption at 7537 kWh per person. However, a silver lining exists with the increase in per capita low-carbon generation. The latest data shows a slight increase from 2025, indicating progress in clean energy uptake despite the overall consumption dip. This growth is encouraging, pointing to a gradual transition towards sustainable electricity generation.

Suggestions

To boost low-carbon electricity generation, California can capitalize on its existing solar infrastructure by expanding solar installations. Looking at successful regions, California can draw inspiration from countries and states with high solar or nuclear contributions. For instance, France and Slovakia excel in nuclear energy, generating more than 65% of their electricity from this clean source. Meanwhile, states like Iowa and Denmark illustrate the successful harnessing of wind power, achieving over 55% wind generation. California should aim for similar achievements by investing in nuclear and solar energies, which can substantially enhance its clean electricity portfolio and lessen carbon footprints.

History

Since the early 2020s, California has experienced a mixed pattern of low-carbon electricity generation. Noteworthy is the decline in hydropower and geothermal contributions over recent years. Conversely, wind energy has seen growth, particularly in 2024 and 2025, though with slight setbacks in 2026. Nuclear power has maintained a relatively stable presence, despite minor fluctuations. The declining trend in nuclear generation over recent years is concerning, as increasing nuclear capacity could significantly reduce fossil fuel reliance. Encouragingly, biofuel contributions have remained constant, further supporting the need for advances in the high-yield, sustainable pathways of nuclear and solar technologies. This would empower California to build a resilient, low-carbon electric grid capable of supporting its growing energy demands in the future.
