How hot does waste heat from data centers get? Is it up to 100 degrees Fahrenheit? Seems like it would be difficult to efficiently transport that heat into nearby homes.
A lot of housing in Sweden is heated using left over heat from the industry (“spillvärme”). The industries actually rely on this for cooling. From what I hear, it’s usually pretty expensive compared to ground/air-to-water heat pumps (1 SEK vs 0.4 SEK per kWh of heat)
And what if the housing gets too hot? Does industry stop because of overheating during hot months?
> it’s usually pretty expensive
So why do people heat that way? Is it legislated into existence? Why? To reduce global warming?
