Three key facts to know about energy in 2025, according to Fatih Birol, Executive Director of the International Energy Agency (IEA).
Renewables are surging. Over 80% of new power plants built last year were fossil fuel-free. But there’s a missing link: the grid.
Nuclear power is seeing a revival. 2025 is on track to be the highest year ever for nuclear electricity generation, since its rise in the 1970s.
Investment in clean energy is also growing, with 85% concentrated in advanced economies.
The message is clear: Renewable energy momentum is building, but equitable access around the world is still a challenge.
