Solar (BTM) Energy: Global Electricity Generation 2025/2026

Solar (BTM) generation in the supplied country figures totals about 710 TWh for the 12 months from July 2025 to June 2026, demonstrating a substantial contribution to clean electricity supply. However, the dataset does not provide a confirmed global total or a global electricity-consumption denominator, so its share of global electricity consumption cannot be calculated reliably. It also lacks figures from a decade earlier, preventing a supported comparison of global generation and share over that period. The available five-year evidence nevertheless shows strong expansion in the United States, where generation increased by about 40 TWh.

People's Republic of China leads the listed countries across total output, national electricity share and generation per person: about 620 TWh, nearly 6% and roughly 440 kWh per person. Its output is around seven times that of the United States, which generates about 90 TWh, supplies roughly 2% of its electricity from Solar (BTM), and produces about 260 kWh per person. The United States is the only country with a supplied five-year growth figure; its increase of about 40 TWh represents growth of roughly four-fifths, rather than evidence of a verified global growth ranking. Among US states, California stands out with about 37 TWh, over 12% of its electricity and 930 kWh per person—well above either listed country's per-person figure. Arizona generates slightly more than Texas, at around 6 TWh each, but its electricity share is nearly 5%, versus less than 1% in Texas.

The climate advantage of expanding this electricity supply is substantial: the supplied IPCC lifecycle figure for solar is 45 gCO2eq/kWh, compared with 820 gCO2eq/kWh for coal, 490 gCO2eq/kWh for gas and 650 gCO2eq/kWh for oil. That puts solar's lifecycle emissions roughly 90–95% below those fossil-fuel sources. Wind, nuclear and solar all provide low-carbon electricity that can help reduce climate-changing emissions and the air pollution associated with fossil-fuel combustion. Building on the approximately 710 TWh recorded here, further solar deployment, alongside expanded nuclear and other clean electricity sources, can support growing electricity demand from electrification and AI.
