# IEA sees global electricity demand growth accelerating to 3.8% by 2027

The International Energy Agency forecasts demand rising 3.6% in 2026 and 3.8% in 2027, up from 3% in 2025, with data center expansion among the drivers; a WRI director says renewables are not growing fast enough to cut fossil fuel use.

Global electricity demand will grow 3.6% in 2026 and 3.8% in 2027, up from 3% in 2025, the International Energy Agency forecast, with data center expansion among the listed drivers.[^2]

The step-up arrives as the AI buildout adds load to the grid. The IEA names industrial growth, electric vehicles, air conditioning, heat pumps, and data center expansion as the forces behind the faster pace.

The World Resources Institute reads the same trend as a warning, not a problem solved. David Waskow, director of the International Climate Initiative at WRI, said the renewable energy growth rate is not enough to reduce fossil fuel use because global energy demand keeps rising. He cited increasing use of cooling systems as the Earth warms, and the growth of artificial intelligence and data centers, as major drivers.[^1]

Taken with Waskow's caution, the IEA's trajectory appears to leave little room for a near-term drop in fossil fuel generation. The question the two readings leave open is whether renewable capacity can build fast enough to meet demand growth that now runs above 3% in the agency's forecast.
