For years, transition skeptics have argued that what’s really happening globally is “energy addition,” where renewables are piling on top of fossil fuels rather than pushing them aside. The data that’s just landing from 2025 finally puts that argument to rest.

For the first time, global electricity generation from fossil fuels fell, not because of a pandemic shutdown, recession, or unusual weather, but simply because renewables grew faster than demand. Power-sector emissions dropped along with it, also a first. Solar recorded the largest single-year increase of any electricity source on record, with the exception of coal’s rebound as the world re-opened after 2020. And renewable generation surpassed coal in the modern era for the first time.

These are just a few of the important findings in Ember’s Global Electricity Review 2026. To unpack what they mean, and what they don’t, we welcome back to the program Nicolas Fulghum, Senior Energy and Climate Data Analyst at Ember and one of the report’s lead authors. Nic was last on the show in Episode #254 reviewing the 2025 edition of this report, which became our most popular episode of the year, and which we re-released without paywall in Episode #266.

In today’s show, we’ll see how the structural decline in fossil generation, long-anticipated by transitionistas, finally arrived. We’ll hear why solar’s growth rate refuses to slow even as the technology matures. And we’ll explore how the second fossil fuel shock of the decade, this time from the Iran war we covered in Episode #272, is pushing more countries to accelerate their move off imported fuels. The energy transition isn’t coming. It’s here, and it’s getting more unstoppable every year.
