Wind turbines may be relatively expensive at the moment, but with the advancements in technology, and costs falling because of mass production, they are certainly one way of ensuring some electrical supply for a lot of people in the future.
I've written before how I lived in the only house in Ossy which had electricity in the blackouts in the seventies, thanks to a windmill on the garage roof that my Dad knocked up out of an old church pew, a wheelchair and some drainpipe.
