Wind farms not that windy

The telegraph explains that wind farms in southern scotland are not providing much energy at all.

This produces 7·7 per cent of the electricity it would if there was enough wind for it to run continuously at full power.

The study says the turbine at GlaxoSmithKline's pharmaceutical plant at Barnard Castle, Co Durham, which is in a built up area and uses second-hand turbines, operates at 8·8 per cent of capacity. "We are really talking about a garden ornament, not a power station. These are statements about the company's corporate social responsibility, not efficient generating capacity," Mr Constable said.
