4 minute read Tuesday, Jun. 23, 2026People everywhere are protesting AI data centres, with good reason. They use a lot of water and energy, and they create a lot of noise. They create relatively few ongoing jobs after construction is complete.
Electricity used to power servers at AI centres creates heat. To keep running they must be cooled. More electricity is used to power chillers to cool the computers. In summer, chillers evaporate water and dissipate heat to the atmosphere. Lots of it. A few Olympic-size swimming pools worth, even in our cold climate.
A 100 MW (100,000 kW) data centre uses enough power to heat about 10,000 homes with electric baseboard heat or an electric furnace. Or about enough to heat 80 acres of greenhouse on the coldest days of January. To put that in perspective, the recently completed Keeyask dam produces about 695 MW of power. A 100 MW data centre uses about 14 per cent of the power produced by the Keeyask dam.
In Finland, a data centre was built under downtown Helsinki. Waste heat from the data centre is recycled to heat the buildings above it.
