Solar Power Breaks All Growth Records in 2025

The world just crossed a milestone that seemed impossible a decade ago: solar power grew faster in 2025 than any energy source has ever grown in a single year.

The Energy Information Agency confirmed this week that solar's explosive rise made 2025 the first year of solar dominance. The renewable energy source generated over 2,700 terawatt-hours last year, more than double its output from just three years earlier.

The numbers tell an even bigger story. Solar alone covered a quarter of the world's rising demand for all forms of energy last year. When you look just at electricity, solar covered over two-thirds of the increased demand.

That growth is changing how we power our lives. Electric vehicle sales jumped nearly 40 percent, reaching a quarter of all cars sold worldwide. Heat pumps are now the majority of new heating units sold in several countries.

The timing couldn't be better. As more people switch to electric cars and heat pumps, we need more clean electricity. Thanks to solar's boom, carbon-free energy sources grew faster than overall demand in 2025 for the first time.

Solar now accounts for over 8 percent of the world's total electricity production. Thirty countries each installed at least a gigawatt of solar capacity last year, making it the single largest grid source by capacity globally.

The solar revolution has a powerful sidekick: batteries. Battery storage capacity grew 40 percent between 2024 and 2025, reaching 110 gigawatts of new capacity. That's more than the highest single-year addition of natural gas capacity ever recorded.

Together, cheap solar and batteries are reducing our need for fossil fuel backups. Coal use barely budged, rising just 0.4 percent. Natural gas use crept up only 1 percent, mainly because of cold weather driving heating demand.

The Ripple Effect spreads beyond just cleaner air. The massive shift to solar and batteries is helping countries prepare for future energy shocks. As electrification accelerates, we're proving we can meet growing demand without burning more fossil fuels.

China led the charge, responsible for 60 percent of global renewable growth. Even as the country commissioned new coal plants, its actual coal use for electricity dropped because solar and wind filled the gap.

The European Union hit its own milestone: coal fell below 10 percent of electricity production for the first time since records began.

The EIA declared we've entered "the Age of Electricity," and the data backs it up. Electricity demand grew at twice the rate of overall energy demand, powered increasingly by the sun.
