Stockholm recycles excess heat from data centres to warm homes

Stockholm is heating residents' homes with the excesses created by data centres. The Stockholm Data Parks partnership is incentivising businesses to move their data centres to the city with a cheap, carbon-positive solution to their need to cool the centres, which heat up as they're used. Currently, data centres use about 3% of the global electricity supply and account for 2% of global warming, giving them the same carbon footprint as the airline industry.
