Summary
Thermodynamics says that all energy will eventually become thermal energy. If you use 1kWh of electrical energy to run a computer, it will emit 1kWh of heat.
To the data center engineer, that’s a problem, because that heat has to be removed or the equipment will overheat.
To the urban planner, that’s an opportunity. The community wants that heat.
Data centers have been offering their waste heat for years. But very little is actually being successfully used.
Data centers offer a predictable supply of heat because they keep their servers running continuously. But the heat is “low-grade:” It is warm rather than hot, and it comes in the form of air, which is difficult to transport.
Sometimes, there are district heat networks, which provide warmth to local homes and businesses through a piped network. If your data center is near one of these, it is a matter of extending it to connect to the data center, and boosting the grade of heat.
