I understand that they did something similar at a certain northern RAF base only 2 (or was it 3 ?) winters ago. Sadly that particular part of Scotland experienced one of its coldest periods (-15, or -16) for several days. The heating had been turned right the way down to save on costs. And lo, a number of buildings suffered from burst pipes due to the cold weather (Scotland? Cold?? In winter???). Cost of repairs far exceeded cost of saved fuel.
As a complete aside, the weather, stunningly clear, very cold and dead flat calm, meant that not a single wind turbine stirred to disturb the Christmas peace.
