Hi!
In cold countries, energy can have two lives : a first life making calculations in a computer, or transforming matter (ore into metal, trees into books), and a second life heating homes.
One needs to build-out quite static-energy-output datacenters (e.g. deploy 10MW at once, and don't grow) for that. Not our business.
But the best is to use no energy at all : see the OLPC project in Afghanistan (A computer with pedals, like the sewing machines of our great-great-great-grand-mothers) (1)
Do you realize that in terms of carbon footprint that is much much less efficient? Look at the title of the thread.
