A large proportion of 'our' electricity, is supplied by French electricity generating companies, and a high percentage of their generating capacity is from nuclear power stations, and many of them are on the French coast (i.e. Flamanville, Paluel, Penly, Gravelines). We are closer to most of the French nuclear power stations than we are to the UK ones!
As a great innovator, the UK was at one point at the forefront of Wind Turbine design and manufacture, but as usual, other countries now seem to be able to build them bigger, better, quicker and cheaper.
We simply don't have the foundries that can turn out these bits of metal big enough. The Victorian engineers will be spinning (at carefully calcutated and regulated revolutions per minute) in their graves...
Until we crack how to produce limitless, free electricity from sea water (conspiracy theorists would say that we probably already know how to but the technology is supressed by the power companies) then we will have to put up with wave hubs, tidal power and wind farms, beacuse no-one wants nuclear or coal fired power stations on land, and wind farms of the scale required to generate enough power on a large scale take up too much space.
Or we can give up our lightbulbs, TV's, games consoles, computers, Sky boxes, fridges, ovens, iPods, mobile phones, power tools... people don't seem to keen on that either!
A few hundred years ago there were probably similar protests about the monstrous new fangled technology harnessing the wind to process grain and hops!
