US leads record global surge in gas-fired power driven by AI demands, with big costs for the climate

Projects this year expected to triple global gas capacity, forecast finds, as concerns grow over impacts on planet

The US is leading a huge global surge in new gas-fired power generation that will cause a major leap in planet-heating emissions, with this record boom driven by the expansion of energy-hungry datacenters to service artificial intelligence, according to a new forecast.

This year is set to shatter the annual record for new gas power additions around the world, with planned and under-construction projects earmarked for 2026 set to nearly triple the amount of existing gas capacity, a report by Global Energy Monitor (GEM) found.
