A data center cannot reuse heat without a buyer
Germany proposed easing a rule that asks data centers to reuse their leftover heat, WIRED reports. Developers say some sites have no nearby customer for that heat. The proposal would check whether reuse is possible; it had not yet passed when the article ran.
What the source reports
WIRED reports on a proposed change to Germany's data-center heat-reuse rule. The existing obligation asked operators to put waste heat to use. Developers objected that a site may not have a nearby buyer or a working way to deliver that heat. The proposed amendment would replace the blanket duty with a check of what is feasible at a given site. It had not been approved by parliament when WIRED reported it. A rule can encourage better siting where heat has a use. It can also be hard to meet where there is no buyer. The source does not establish that every canceled project was caused by this rule, or that changing the rule will cut emissions. The AI Agency digest asks planners to name a real heat customer and compare sites before claiming a climate benefit. That is its suggested test.
