Energy Efficiency - Data Centers

I guess that is one reason why Google built a huge data center in Finland. Access to very cool water. Not to mention good wholesale electricity rates. And yes, since the electricity is not converted into mechanical work, it must all end up as heat.

Hi Merik,

This aligns with what I'd expect. Essentially every watt of
electricity in to the data center is a watt of heat that must be
removed from the data center. Did you know some computer room air
conditioners actually cool the air at fixed compression and then
re-heat it with a resistive electric element to reach the desired
cooling output? Insane!
