Renewable Energy Beats Coal for First Time in a Century

The global energy system just passed a milestone that seemed impossible a decade ago: renewable sources are now generating more electricity than coal for the first time since the Industrial Revolution.

Solar and wind power met 90% of the world's electricity demand growth in 2025, with solar alone accounting for three-quarters of that increase. Together, these clean energy sources are expanding faster than any electricity technology in recorded history.

The numbers tell a remarkable story. Solar electricity generation has doubled roughly every three years for the past eight years. Wind power has more than tripled since 2015. Meanwhile, electricity from fossil fuels actually declined slightly in 2025, the first drop ever recorded.

What changed? The cost of solar panels has plummeted 90% since 2010, while wind energy costs fell 70% during the same period. Battery storage, which helps keep the lights on when the sun sets and wind stops, dropped 90% in cost between 2012 and 2025.

Renewables now account for 34% of all electricity worldwide, up from just 4.4% for solar and wind combined a decade ago. In 2025 alone, the world added 629 gigawatts of renewable capacity, enough to power hundreds of millions of homes.

The growth shows no signs of slowing. Over 85% of all new electricity generation built in 2025 came from renewable sources. The International Energy Agency projects solar and wind will double their share to 30% of global generation by 2030.

Government policies supporting clean energy and corporations buying renewable power have accelerated the shift. But the primary driver is simple economics: in most places, building new solar or wind farms is now cheaper than running existing coal plants.

Battery technology is solving the reliability puzzle too. New battery storage capacity in 2025 was 150 times higher than a decade ago, allowing grids to store sunshine and wind for when they're needed most.

The Ripple Effect

This energy transformation reaches far beyond electricity bills. Cleaner air from reduced coal burning improves public health in communities worldwide. The renewable energy industry is creating millions of jobs in manufacturing, installation, and maintenance. Entire regions that once depended on coal mining are retraining workers for solar panel installation and wind turbine service.

Countries are gaining energy independence by harnessing their own sun and wind instead of importing fossil fuels. Remote villages that never had reliable electricity are leapfrogging straight to solar power, bringing light, refrigeration, and internet connectivity for the first time.

The shift is happening in wealthy and developing nations alike, proving clean electricity works at every economic level. China, Europe, and the United States are leading capacity additions, but solar installations are booming across Africa, Latin America, and Southeast Asia too.

After more than a century of fossil fuel dominance, the global electricity system is being rebuilt on renewable foundations in real time.
