Data centers to use almost 4 times more power by 2035, BNEF says

What the report says. BNEF expects data center electricity use to almost quadruple to 2,354 TWh by 2035, or 7% of global demand. The report, Powering the Data Center Boom, was commissioned by Bloomberg Philanthropies. It reviews policies in 17 markets that try to speed up grid connections for large loads.

Why gas. Grids in the US and Europe cannot connect big new loads fast enough. Bringing AI capacity online quickly pays well, so some developers build gas plants on site and wait for the grid with a working data center. BNEF tracked 181 GW of such announced gas projects, more than 90% in the US. BNEF itself warns this shows potential scale, not a forecast of what will be built.

The climate bill. If all announced on-site gas plants for US data centers were built and run, BNEF estimates they would emit about 345 million tonnes of CO2 equivalent a year. That is 152 million tonnes more than if the same data centers used average US grid power, equal to 10% of US power-sector emissions in 2025. BNEF adds that once online, the economics could keep these plants running even after a grid connection arrives.

Emerging markets. In India, data center demand is set to rise from 11 TWh in 2025 to 91 TWh in 2035, in Malaysia from 7 to 45 TWh. In Brazil, BNEF expects almost all extra demand to be met by renewables. In Indonesia, coal and gas supplied 82% of state utility PLN's on-grid power in 2025, and data centers cannot yet contract directly with independent renewable generators.

Keep in mind: this is an analyst forecast, not a government decision. BNEF says there is still limited evidence on which grid connection policies work best. Bloomberg, writing about the report, notes that governments around the world are looking for ways to connect data centers faster to curb reliance on on-site gas.
