Efforts to capture and repurpose waste heat from industrial and digital sources are gaining traction as a method to improve energy efficiency and security. In the United States, Virginia has passed legislation (HB 323) directing state energy officials to study connecting data centers to heat users, a move intended such as greenhouses, to address local opposition to facility expansion by modeling solutions used in Europe. the Nordics and the Netherlands. In Denmark, a Meta-owned data center in Odense has successfully integrated its server heat into the local district-heating network using network. Using ammonia heat pumps, providing heating for pumps designed by Ramboll to upgrade captured heat to temperatures between 70 and 75°C, the infrastructure has provided approximately 165,000 megawatt-hours of heating, serving roughly 11,000 local households. Broader analysis from the engineering firm Danfoss suggests that large-scale waste heat recovery could significantly reduce European dependence on gas. The report notes that reusing heat from sources such as factories, supermarkets, wastewater treatment plants, and data centers could save Europe up to 140 billion euros annually. In Germany, industrial waste heat alone has the potential to meet more than 30 percent of the nation’s central heating demand. Additionally, one Danish aluminum manufacturer has already transitioned away from gas by utilizing waste heat processes. As the rise of artificial intelligence drives increased electricity demand, European data center consumption is projected to grow from 96 TWh in 2024 to 236 TWh by 2035. To manage these needs, companies like the UK-based EkkoSense are deploying sensor-based monitoring to reduce cooling energy usage, recently achieving an average 15 percent reduction at 20 Virgin Media O2 data centers.
