Extreme heat drives US power prices up and disrupts travel during Independence Day weekend

A severe heat wave across the central and eastern US is expected to continue through the Independence Day weekend, pushing temperatures up to 105°F (40.5°C). This surge in heat is causing electricity demand and wholesale power prices to spike dramatically, with increases over 100% in some areas like New England and New York City. The heat wave is straining power grids, prompting officials to urge energy conservation, and is also causing travel delays on rail and road due to heat-related equipment issues. The event highlights the growing impact of climate change on extreme weather and infrastructure stress during peak travel periods.
