There’s an influence crunch looming as AI and cloud suppliers ramp up knowledge heart building. However a brand new report suggests {that a} resolution lies beneath their foundations.
Superior geothermal energy may provide practically two-thirds of latest knowledge heart demand by 2030, in line with an evaluation by the Rhodium Group. The additions would quadruple the quantity of geothermal energy capability within the U.S. — from 4 gigawatts to about 16 gigawatts — whereas costing the identical or lower than what knowledge heart operators pay as we speak.
Within the western U.S., the place geothermal sources are extra plentiful, the know-how may present 100% of latest knowledge heart demand. Phoenix, for instance, may add 3.8 gigawatts of knowledge heart capability with out constructing a single new standard energy plant.
Geothermal sources have monumental potential to offer constant energy. Traditionally, geothermal energy crops have been restricted to locations the place Earth’s warmth seeps near the floor. However superior geothermal strategies may unlock 90 gigawatts of fresh energy within the U.S. alone, in accordance to the U.S. Division of Power.
Superior or enhanced geothermal encompasses a variety of approaches, however typically they drill deeper and wider than earlier than. That enables them to entry hotter rocks — which interprets into extra energy — and pack extra geothermal wells onto a single property. The sector has seen a surge of startups lately, pushed partly by data and know-how borrowed from oil and gasoline corporations.
Fervo Power, for instance, was based by former oil and gasoline engineers to increase geothermal’s potential utilizing horizontal drilling strategies perfected over the previous couple of many years. The corporate raised over $200 million in 2024 on the heels of serious price reductions in effectively drilling.
One other startup, Bedrock Power, is drilling deep to attenuate geothermal’s footprint, permitting space-constrained workplace buildings and knowledge facilities to extract extra energy from their restricted footprints. The corporate’s specialised drilling rigs bore down greater than 1,200 toes to faucet constant warmth year-round.

Quaise Power’s know-how appears like one thing out of science fiction. The startup vaporizes rock utilizing microwaves generated by gyrotrons. By skipping conventional drill bits, Quaise hopes to drill as deep as 12.4 miles (20 kilometers). At that depth, the rocks are practically 1,000°F year-round, providing practically limitless quantities of warmth to drive turbines or heat buildings.
Whereas most corporations are utilizing Earth’s capability to offer and retailer warmth, one other startup is utilizing it to retailer vitality one other approach. Sage Geosystems has been injecting water into wells beneath strain. When energy is required, it will probably open the faucets and run the water by a turbine, kind of like an upside-down hydroelectric dam.
As a result of geothermal energy has very low working prices, its worth is aggressive with knowledge facilities’ vitality prices as we speak, the Rhodium report stated. When knowledge facilities are sited equally to how they’re as we speak, a course of that usually takes into consideration proximity to fiber optics and main metro areas, geothermal energy prices simply over $75 per megawatt hour.
However when builders account for geothermal potential of their siting, the prices drop considerably, right down to round $50 per megawatt hour.
The report assumes that new producing capability could be “behind the meter,” which is what specialists name energy crops which can be attached on to a buyer, bypassing the grid. Wait occasions for brand spanking new energy crops to connect with the grid can stretch on for years. In consequence, behind the meter preparations have change into extra interesting for knowledge heart operators who’re scrambling to construct new capability.
