I heard Google moved to Washington State for the cheap hydropower

Google is actually building data centers at many locations based on
what costs they incur and (particularly) what local subsidization for
building they can reap.
Cheap power is a factor, but cheap cooling is a factor too for large
data farms.
As a rough estimate in most climates, for every dollar you pay for
electricity to run the computers, you must pay two dollars for the
electricity to run the AC to cool the computers.
If you can be clever and use large bodies of water as a cooling
reservoir for many situations, you come out way ahead. (Ever notice
where power plants, especially nuclear, tend to be located?)
Tim.
So why is Google building a unit here in my neighborhood ?-;
Tax incentives by local and state governments are a huge factor, too.
A data center is actually not too much different than a fab. A fab has
lower but still non-negligible energy and water needs, and they are
put willy-nilly according to local tax incentives.
