Power savings?

Considering one Sun Blade rack is about 5KW (+ approx 2.5KW Cooling), then this is just a token gesture from Intel. Solar or wind can only really work, when we have a very good way of storing generated electrical energy.

Green datacentres are really a myth. The computers we buy are getting more power efficient, but also generally smaller. So we pack in lots of smaller systems in with no resultant reduction of power consumption.
