Renewables covering all new power demand this year

 From Electrek


Solar and wind are growing fast enough to meet all new electricity demand worldwide for the first three quarters of 2025, according to new data from energy think tank Ember. The group now expects fossil power to stay flat for the full year, marking the first time since the pandemic that fossil generation won’t increase. [Recall that the Covid Crash led to a deep, though short-lived, recession.  2025 is not a recession year, though 2026 may be]



Solar and wind aren’t just expanding; they’re outpacing global electricity demand itself. Solar generation jumped 498 TWh (+31%) compared to the same period last year, already topping all the solar power produced in 2024. Wind added another 137 TWh (+7.6%). Together, they supplied 635 TWh of new clean electricity, beating out the 603 TWh rise in global demand (+2.7%).

That lifted solar and wind to 17.6% of global electricity in the first three quarters of the year, up from 15.2% year-over-year. That brought the total share of renewables in global electricity – solar, wind, hydro, bioenergy, and geothermal – to 43%. Fossil fuels slid to 57.1%, down from 58.7%.

For the first time in 2025, renewables collectively generated more electricity than coal. And fossil generation as a whole has stalled. Fossil output slipped slightly by 0.1% (-17 TWh) through the end of Q3. Ember expects no fossil-fuel growth for the full year, driven by clean power growth outpacing demand.

China and India are partly driving that shift. In China, fossil generation fell 52 TWh (-1.1%) as clean energy met all new demand, resulting from a structural change in its power system. India saw fossil generation drop 34 TWh (-3.3%), thanks to record solar and wind growth and milder weather.

Solar is doing the heavy lifting. It’s now the single biggest driver of change in the global power sector, with growth more than three times larger than any other electricity source in the first three quarters of the year.

“Record solar power growth and stagnating fossil fuels in 2025 show how clean power has become the driving force in the power sector,” said Nicolas Fulghum, senior data analyst at Ember. “Historically a growth segment, fossil power now appears to be entering a period of stagnation and managed decline. China, the largest source of fossil growth, has turned a corner, signaling that reliance on fossil fuels to meet growing power demand is no longer required.”

Electricity demand rose 2.7% in the first three quarters of 2025, far slower than the 4.9% jump seen last year when extreme heatwaves pushed up cooling demand in China, India, and the US. This year’s milder weather helped take some pressure off the grid, making it easier for clean energy to close the gap.

For the first time outside of major crises such as the pandemic or the global financial crash, clean energy growth has not only kept up with demand but surpassed it. The next big question: can solar, wind, and the rest of the clean power sector keep up this pace consistently? If they can, 2025 may be remembered as the year global fossil generation plateaued.

I talked about EMBER's report for the first 6 months of 2025, here.  The conclusions are pretty much the same.  Renewables are beating fossil fuels, partly because of slower demand growth because of cooler summers, as well as because of massive growth in wind and solar.   So it is possible that in 2026, hot summers and higher economic growth will increase demand again, by more than the rise in electricity generated by renewables.  But it is unlikely, and if it does happen, renewables will overtake demand again in 2027.  Emissions have probably peaked.  Even if their decline will be slow, at first.
