Solar and Wind Just Beat Coal as Top Global Energy Source

The world just crossed a threshold no one thought would happen this soon. Solar and wind power surpassed coal as a global energy source in 2025, marking a historic turning point in how humanity powers itself.

The numbers tell an incredible story. More than 600 gigawatts of solar electricity came online last year, led by China and including India, Brazil, Vietnam, the European Union, Kenya, and Mozambique. Solar and wind electricity generation jumped 109% worldwide, according to Ember Energy Research.

This isn't happening because of government mandates or environmental activism alone. It's happening because solar and wind became the cheapest options. Utility-scale solar now costs between four and eight cents per kilowatt-hour, while natural gas costs 13.8 to 26 cents and coal costs even more.

The economics shifted so dramatically that investment in clean energy reached $2.2 trillion in 2024, double the $1.1 trillion invested in new fossil fuel projects, according to the International Energy Agency. Companies and countries are choosing renewables because they save money, not despite the cost.

Even the United States, where political headwinds blow against climate action, saw massive renewable growth. Solar generation jumped 37% last year and wind grew 12%. Renewables now provide 24% of all U.S. electricity, and in March 2025, they supplied more than half the nation's power for the first time ever.

Africa is leaping straight to renewables as new regions get electricity for the first time. Rather than building coal plants and gas infrastructure, countries are installing solar and wind, bypassing fossil fuels entirely the way mobile phones let developing nations skip landline networks.

Solar alone accounted for 85% of all new electricity added to the U.S. grid last year, according to the Solar Energy Industry Association. The cost of utility-scale solar fell 85% between 2010 and 2020, and prices dropped again in both 2023 and 2024.

The Ripple Effect

This energy revolution is reshaping assumptions about what's possible. Climate author Bill McKibben calls the dramatic reduction in clean energy prices one of the biggest climate developments happening right now, something that's "shaking up all of our assumptions."

Countries that once had no choice but fossil fuels now have a cheaper, cleaner alternative. Communities breathing polluted air near coal plants have an economic argument for change, not just an environmental one. The transition that seemed decades away is happening faster than experts predicted because the math simply works.

Solar and wind are no longer "alternative energy." They're becoming the main source of new power across the globe, driven by economics as much as environmental concern.

The future runs on sunshine and wind, and it costs less than anyone imagined.
