On 27 June 2023, Texas once again braced for a record spike in electricity demand as 110F heat spurred air-conditioning usage. An early heat wave gripped the second most-populous US state, buckling highways, stressing oil refineries and pushing up natural gas prices. At least two deaths were attributed to the searing temperatures and it was only expected to get hotter as the week wears on. It was not a new problem for Texas: The Lone Star State broke power-demand records 11 times in the summer of 2022. Graphic: Bloomberg
