A Statista chart built on International Energy Agency figures maps the electricity sources expected to power data centers through 2035. Global electricity demand from data centers is projected to more than double over the next five years, with the increase driven largely by AI workloads.

By the end of the decade, roughly half of global energy demand for data centers is expected to come from renewables, including solar PV, wind and hydro. Renewables are the fastest growing supply source in the chart. Natural gas and coal rank next in importance for 2030, and nuclear power takes on a larger role.

US figures in the chart show solar PV generation serving data centers reaching 97 TWh in 2035. Wind scales up from 28 TWh to 83 TWh over the ten-year window, close to double the level shown for China. Coal generation serving US data centers declines from 28 TWh to 7 TWh across the same period.

In China, solar PV for data centers climbs from 7 TWh in 2025 to 83 TWh in 2035, and wind reaches 44 TWh in 2035. The chart shows the mix in each market tracking the availability and cost competitiveness of local generation. Coal holds a larger share of electricity generation in China, while natural gas holds a larger share in the United States. Nuclear output rises significantly in both countries over the period covered.
