Perched on a fell above the Lakeland town of Ulverston, just down the road from me, are four wind turbines. They’ve been turning steadily since 1997. The turbines all look the same. But one of the four is very different. It was the first in the UK to be owned by local people, who established a co-operative to buy shares in the turbine. The other three are owned by a commercial renewables developer.
