While temperatures across the eastern United States pushed past 100°F last week, the US Department of Energy quietly scrubbed roughly 6,000 energy conservation pages from its public website. The timing was striking — and the political context makes it hard to read as anything but deliberate.
- The DOE removed roughly 6,000 energy conservation pages from its website while a historic heatwave baked the eastern US.
- The deletion of energy conservation pages followed Republican fury over New York Mayor Zohran Mamdani’s advice to set AC to 78°F.
- Temperatures in New York City exceeded 100°F for two consecutive days, putting enormous strain on the electrical grid.
- The Internet Archive preserved the deleted pages, which also covered water conservation, insulation, and the Solar Decathlon program.

What Was Actually Deleted
The scope of the DOE’s purge goes well beyond the thermostat tips that kicked off the political controversy. According to reports, the deleted energy conservation pages spanned topics including water conservation, types of residential insulation, and the department’s Solar Decathlon challenge — a long-running competition that tasks university teams with designing energy-efficient homes. None of that has any obvious connection to the political spat that appears to have triggered the deletion. It’s a broad, indiscriminate sweep, not a targeted removal.
The good news, if there is any, is that the Internet Archive captured much of what was lost. The Wayback Machine has become an essential piece of digital infrastructure precisely because of moves like this — government content that exists one day and vanishes the next, with no official explanation offered.
The Political Spark: Mamdani’s Thermostat Advice
The chain of events that apparently led here started with New York City Mayor Zohran Mamdani doing something entirely unremarkable: asking residents to set their air conditioning to 78 degrees during a brutal heatwave to reduce strain on the city’s electrical grid. This is, to be clear, exactly what energy officials and grid operators routinely ask people to do when temperatures spike. It is not a fringe position. It’s not ideology. It’s load management.
Republicans, however, treated it as a provocation. Senator Ted Cruz — who famously boarded a plane to Cancún while Texas froze during the 2021 winter storm — weighed in with predictable outrage. Nikki Haley and Representative Nancy Mace of South Carolina joined the pile-on, with Mace framing the 78-degree recommendation as an attack on women going through menopause. The GOP, a party that has spent years insisting it has no interest in policing what happens in people’s bedrooms or bodies, was apparently very concerned about what temperature those bodies are kept at.
What got lost in the dunking and the discourse is that the DOE’s own energy conservation pages — until last week — officially recommended thermostats set between 75 and 78 degrees during warm weather. Greg Abbott, the Republican governor of Texas, has made the same ask of Texans during summer heat events. This wasn’t Mamdani going rogue. It was consensus advice from energy professionals, suddenly recast as radicalism.
Energy Conservation Pages and Public Safety — Why This Actually Matters
Strip away the politics and you’re left with a straightforward public health problem. New York City recorded temperatures above 95°F for four consecutive days during the heatwave, including two days where the mercury cleared 100°F. That kind of sustained heat puts enormous pressure on the grid — particularly over a holiday weekend when residential demand spikes as people stay home and run their AC continuously.
The reason energy conservation pages exist isn’t to lecture people or to push an environmental agenda. It’s to prevent blackouts. When demand outstrips supply, grid operators have to cut power — and people lose air conditioning. During a heatwave, losing AC isn’t just uncomfortable. It can be fatal. The CDC and NOAA data is unambiguous on this point: extreme heat kills more Americans each year, on average, than floods, tornadoes, and hurricanes combined. It is the deadliest category of weather-related disaster in the country, and it’s chronically underestimated by the public because it doesn’t produce the dramatic imagery that a tornado or a hurricane does.
Deleting practical guidance about how to reduce energy use during these conditions — guidance that could help prevent the kind of cascade failures that lead to blackouts — is not a neutral act. It has real-world consequences for real people who rely on that information.
A Pattern of Digital Erasure
This isn’t the first time the current administration has made inconvenient information harder to find. Since January 2025, federal agencies have removed or restructured web content related to climate data, public health guidance, and environmental regulation at a pace that has alarmed researchers, journalists, and archivists. The DOE purge of energy conservation pages fits a recognizable pattern: when a political controversy intersects with official government content, the content disappears.
What makes this particular episode unusual is the speed and scale. Six thousand pages is not a minor housekeeping exercise. That’s a systematic dismantling of a public resource that took years to build — one that served homeowners, contractors, policymakers, and educators. Much of it had nothing to do with thermostats or the Mamdani controversy at all.
The Internet Archive’s role here is worth thinking about carefully. The Wayback Machine was designed to preserve the open web — a kind of collective memory for digital content. It was never meant to serve as the primary backup for US government public information. The fact that it’s increasingly functioning in that role says something troubling about where we are.
What Comes Next
Heatwaves are getting longer, more intense, and more frequent. The National Oceanic and Atmospheric Administration has documented a clear upward trend in extreme heat events across the continental United States, and summer 2025 is shaping up to stress-test electrical infrastructure in ways that grid operators are openly worried about. Against that backdrop, removing publicly accessible energy conservation pages — the kind of practical, actionable information that helps ordinary people reduce their energy use and stay safe — is a strange priority.
There’s a harder question lurking underneath all of this: if the federal government won’t maintain basic public information about how to use energy wisely during a climate-accelerated summer, who picks up that responsibility? State energy offices can do some of it. Utilities publish their own guidance. Nonprofits fill gaps. But none of that replaces the reach or the authority of federal resources — especially for lower-income households who may be navigating these questions without professional help. The deletion of 6,000 energy conservation pages isn’t just a political statement. It’s a withdrawal of public service at exactly the moment that service is needed most.
