“I thought, ‘That’s interesting—we need heat,’” Goodman says of Bathhouse. Mining facilities typically use fans or water to cool their computers. And pools of water, of course, are a prominent feature of the spa. It takes six miners, each roughly the size of an Xbox One console, to maintain a hot tub at 104 °F. At Bathhouse’s Williamsburg location, miners hum away quietly inside two large tanks, tucked in a storage closet among liquor bottles and teas. To keep them cool and quiet, the units are

The Trump administration has touted its desire to achieve energy independence for America. It has also made a big deal out of cutting the administrative red tape that it believes slows the development of fledgling industries. So why, one might wonder, would Secretary of the Interior Doug Burgum halt the development of a major offshore wind farm over supposed concerns that the Biden administration “rushed through its approval without sufficient analysis?” That’s a rhetorical question, of course.

A new report from the International Energy Agency digs into the details of energy and AI, and I think it’s worth looking at some of the data to help clear things up. Here are four charts from the report that sum up the crucial points about AI and energy demand. 1. AI is power hungry, and the world will need to ramp up electricity supply to meet demand. This point is the most obvious, but it bears repeating: AI is exploding, and it’s going to lead to higher energy demand from data centers. “AI

Fusion startups have a tough row to hoe. Their mission? To create a new kind of power plant that produces more energy than it consumes — something no one has ever done with fusion energy before. That means proving their technology works, showing it can be scaled up, and convincing investors it can all be done profitably. That’s already a tall order. But there’s another big challenge that gets far less attention: where to get the fuel. Most fusion startups will say that they’ll be producing thei

But what we know for sure is that they’re driving up energy demand and emissions today—especially in the regional pockets where data centers are clustering.

Editor's take: The internet is vast, sprawling across server farms, fiber-optic cables, and satellites. But beyond its physical infrastructure, does the internet – the data, the information, the very essence of cyberspace – have any measurable weight?
