Several things I noticed about the windmills shown in the photos.
The big old windmills used for grinding grain that you see only work if cloth is put on the wooden sail frames, and none of them have the cloth on them that would allow them to work.
The Southern Cross type windmills in the photos all have their tails turned so that they're in line with the blades. This stops them from turning, as it keeps the blades angled at the same direction the wind is blowing instead of at 90 degrees to it.
Those huge white three bladed fibreglass monsters that are blighting the land have to be started by diesel engines mounted at the top of the pylon of each of them, as the blades are too heavy to be turned by the wind alone.
Also, in the UK the wind doesn't blow all the time, so we end up with intermittent power output from the massive windfarms that the gov't has invested in. So we still need coal or oil and atomic powerstations to keep the national grid working.
As the UK is an island, we are surrounded by seas, and the North Sea and Irish Sea in particular are both infamous for the storms and heavy wave actions in both. This could be utilised either instead of, or as well as the wind farms in order generate massive amounts of power. Furthermore, wave and tidal power is constant, so putting turbines across the Severn estuary (where the tidal change is over 20ft) would be a very good way of generating power without losing any of the aesthetics of the area, unlike the monstrous three bladed propellors that look as though they're trying to lift off vast areas of countryside.
