Clean power met all new global electricity demand in 2025, Ember says

Overview

Global electricity demand kept rising in 2025, but this time clean power kept up with all of it. In Ember's Global Electricity Review 2026, released on April 21, 2026, the think tank said clean electricity generation grew by 887 terawatt-hours last year, ahead of the 849 terawatt-hour increase in global demand.

That does not mean the power transition is finished. It does mean the argument has changed. For years, the central worry was that renewables were growing, but not fast enough to meet rising demand without fossil power doing most of the heavy lifting. Ember's new numbers suggest that, at least for 2025, solar and wind expansion was finally large enough to absorb new load growth before fossil generation had to step in.

Global electricity demand kept climbing, but clean power climbed faster

The headline is simple because the math is simple. According to Ember, global clean generation rose more than overall global electricity demand did. Solar was the biggest driver, with output up 30% in 2025, and Ember said solar alone supplied roughly three-quarters of the rise in electricity demand. Wind covered much of the rest.

That is why this report matters beyond climate politics. Power grids do not care about slogans. They care about whether enough electricity shows up when demand rises. If clean sources can add generation at a pace that matches new demand, the transition starts looking less like a burden and more like the default build path.

There is another milestone buried in the figures. Ember said renewables reached 34% of global generation in 2025, just ahead of coal at 33%. That is not the same as saying coal is gone. Far from it. But it is a visible sign that the old order is under pressure from scale, not just from policy speeches.

Why batteries mattered more than they used to

This is not only a solar story. It is also a storage story. Ember said about 14% of additional solar generation in 2025 was shifted to other times of day through battery deployment. That matters because the old criticism of solar was always timing: plenty of supply at midday, not enough when demand peaks later.

Battery costs have fallen hard over the past decade, and deployment is now changing how quickly grids can use cheap daytime solar without wasting it. Recent market reporting points in the same direction. Large battery projects are lining up across the United States, Europe, China, and Australia because storage is becoming one of the fastest ways to add flexible capacity when electricity demand is rising and fuel markets are shaky.

That flexibility is especially important now. Data center growth, electric transport, and hotter weather are all making power grids more demanding. A grid that adds solar without storage will hit limits sooner. A grid that adds both starts to look much more capable of handling sustained demand growth.

China and India made the result much harder to dismiss

One reason Ember's finding carries weight is that it was not built only on small rich-country markets. China drove more than half of the increase in solar generation, and India also posted record clean-power additions. Those are the markets that matter for the next decade because they combine scale, industrial demand, and fast-changing electricity needs.

India is especially important in this story. For years, its economic growth was tied tightly to coal growth. Ember's review says India added enough clean generation in 2025 to outpace its rise in electricity demand, while fossil fuel generation fell. That does not mean India is suddenly off coal. It means the old assumption that fast growth automatically locks a country deeper into fossil power is becoming less reliable.

China's role is even larger. It remains the biggest clean-energy builder, the biggest exporter of many clean-energy components, and one of the few countries capable of moving global deployment curves by itself. When China and India both show this kind of movement in the same year, it becomes harder to argue that renewables are still a side lane.

The next test is whether fossil generation starts a real decline

There is still a large caveat here. One year of clean growth beating demand growth does not guarantee a straight-line future. Fossil generation stayed roughly flat in 2025. That is better than another year of clear growth, but flat is not the same as falling fast enough for climate targets.

The next phase depends on three things: faster grid buildout, faster storage deployment, and broader electrification of transport, heating, and industry. If electricity demand rises because more activity shifts away from oil and gas, power grids will need even more clean capacity than they did in 2025. Grid bottlenecks, slow permitting, and uneven regulation could still slow the transition.

Still, the center of gravity is shifting. The latest global electricity demand figures suggest that clean energy is no longer just chasing growth. It is starting to shape it. That is a bigger story than one good year.
