Several outlets report that the US Department of Energy has removed thousands of web pages about energy conservation amid a historic heatwave affecting the United States. According to reporting, about 6,000 pages covering topics such as thermostat guidance, water conservation, and insulation tips were taken offline. The timing is described as closely following political backlash from Republicans after New York City Mayor Zohran Mamdani asked residents to help reduce strain on the electric grid by setting air conditioning to 78 degrees.
The pages are no longer accessible on the current government website. One report says the Internet Archive’s Wayback Machine is now the primary place where the guidance can be found. Both accounts characterize the deletion as unexpected and raise questions about why the materials were removed while heat impacts are intensifying across multiple states. Neither source includes a confirmed official explanation for the deletions, and the reports rely on the original outlet’s characterization of the removal as a “purge.”
