A DATA CENTER DOES NOT BECOME GREEN BECAUSE SOMEONE PUTS THE WORD “GREEN” IN A PRESS RELEASE.
Denmark attracts data centres for boring, good reasons: reliable infrastructure, strong fibre connections, a cooler climate and an electricity system with a large renewable share. In 2024, renewable sources accounted for 79.7% of Denmark’s electricity supply, according to the Danish Energy Agency.
That makes Denmark a better place to run servers than a grid built mostly on coal. It does not make servers free.
The electricity question is real
Data centres use a lot of power. Denmark’s Energy Agency has been blunt about that for years: rising data-centre demand changes national electricity planning, grid needs and the pace of renewable build-out. The agency’s current planning materials still treat data centres as their own major demand category. That is the grown-up version of the story.
If a company adds a huge new electricity load, the answer cannot just be “don’t worry, it buys certificates.” The questions are: Is enough clean generation being built? Can the grid carry it? Is excess heat used where possible? Is energy and water efficiency measured in public?
What Denmark should insist on
Good data centres can help support digital services, jobs and heat recovery. Bad ones are simply very large machines asking the public energy system to absorb their costs. Denmark should welcome the first and interrogate the second.
This is not anti-tech. It is pro-standards. A country that is proud of its renewable power should be even more demanding about who gets to consume it — and what they give back.
