Energy saving ace in the hole unveiled

The business manager of Hazel Grove High in Stockport, England has shaved £16,000 off his schools' £100,000 per year energy and water bill and slashed its 530 tonne carbon payload in the process.

How was this possible? You'd expect some fairly imaginative and dramatic compromises to be implicated wouldn't you. If you guessed that they've revised the dinnertime menu so as to feature nothing but salad and sandwiches, or ditched the traditional boiler-powered heating system in favour of an exercise-while-you-learn personal heat-generating programme you'd be way off the mark.

The solution - as proposed by an eco-friendly 'hit squad' - was to switch off their 500 computers when they weren't in use i.e. after the kids' home time, at the weekends and during school holidays when not a soul would be on the premises to even consider making a single key press.

Pure genius! If you're in the market for a cushy career change you could do much worse than becoming an energy consultant.
