US heatwave to test power grid amid soaring AI-driven energy demand

Power grid operators in the United States are warning that a dangerous heatwave could put more strain on an electric grid already under pressure from surging energy consumption. A stretch of extreme heat is expected to intensify across much of the central and eastern parts of the country this week, peaking from Tuesday through Thursday. Temperatures this week are forecasted to climb above 38 degrees Celsius (100 degrees Fahrenheit) from Boston to Washington, DC, pushing up demand for air conditioning. The heatwave coincides with two major events on the US calendar. Saturday's holiday marks the 250th anniversary of the US's independence, and millions are expected to gather for barbecues, parades and fireworks.
