Maybe relocate to get cheaper juice?
With the electricity price you mention in the article, it would obviously be cost effective to move your computing center to a different location and/or get a different electricity supplier.
10p for a kWh is way over what one should have to pay these days: Even if I add the annual fee to my retailer and the transport cost to the company which owns the wires to my house, I pay only a fraction of that as a low-volume private buyer on the spot market.
