So Google uses 103 mw for it's server farm? Here's the answer. From the article in Harper's:
"the servers require a half watt in cooling for every watt used in processing."
So solar powered geo heat exchange cooling would knock off 33%.
And a solar mirror CSP generating system on the roof and over the parking lot would produce enough electric power to more than offset the use of the hydropower. And thermal power storagw could even keep the servers going after dark, freeing up all the hdropower to backup a renewable smart grid. Get smart Google, smart grid.
Google could get this done, if someones lets them know it is possible. Google, just google. "Geo heat exchange cooling grist amazingdrx".
There it is..
