The “data-centre boom” is driving a surge in gas investment in the US, pushing its fossil-power spending ahead of China, according to the International Energy Agency (IEA).

A rapid expansion of data centres across the nation is at the heart of the US tech sector’s plans to continue “dominat[ing]” the global artificial intelligence (AI) industry.

High demand for electricity to power these data centres has led to companies rushing to build new gas-fired power plants across the country.

This trend, combined with “soaring” gas-turbine prices, drove a threefold increase in US gas‑power investment in 2025 – and the IEA expects this to continue throughout 2026.

As the chart below shows, Chinese investment in coal- and gas-fired power is expected to drop this year, amid domestic policy changes and the Iran war sending gas prices spiralling.

Together, these trends mean the IEA expects US investment in fossil-fuelled power plants to overtake China’s in 2026.

The IEA’s latest world energy investment report shows that spending on renewables and electricity grids continues to dominate at the global scale.

In the US, Trump administration policies such as the phase-out of tax credits for renewables has led to the IEA revising its forecast for new wind and solar power downwards.

At the same time, US electricity demand is expected to rise by an average of 2% per....
