Solar Achieves Record Growth in 2025, Supplying Over 8% of Global Electricity
In 2025, solar photovoltaic generation increased by 600 terawatt-hours globally, marking the largest annual growth for any electricity source, according to the International Energy Agency (IEA). This surge brought total solar generation to nearly 2,700 terawatt-hours, accounting for over 8% of global electricity supply. The growth was particularly notable in China, the United States, India, and the Middle East, where solar generation rose by at least 20%. Despite this progress, challenges remain in managing midday power surpluses and integrating solar energy into grids effectively. The IEA emphasized the need for coordinated planning of generation, storage, and transmission to maximize solar's potential.
