I think they should be all around the coastline of the UK and that we should build enough to in the future be able to provide power to as much of the country as possible.
Oh, no! Bad idea. Someone's already mentioned the noise, but there's the visual pollution, too. They turn the beautiful English countryside into something resembling Teletubby land. It's hard enough finding a part of this country where mans infrastructure's not a visual blight, without adding those monstrosities.
But, you do have a point in that our government does need to urgently address the problem of providing new means of power generation, and wind turbines are certainly one thing to be considered, though preferably off-shore. There are lots of other options, too; I remember coming across a project using geo-thermal energy, in Malvern, a while back, but I don't know whether that's something that can be applied on a large scale. Then there's the much talked of Severn Barrage. That would really provide a significant input. Trouble is, though, tides are of a cyclical nature both on a daily basis, with flow speeds varying between high and low water, and those daily maximums varying over the course of a month. Similar problems, but of a less predictable nature occur with wind turbines. In particular, during the coldest months of the year in the UK, when electricity demand is at its highest, we often have large areas of high pressure with slack winds sat over us.
So, that brings us nicely to nuclear power. That is the only currently viable, reliable, relatively environmentally friendly option. I'd suggest it should be used in parallel with things like wind turbines, until reliable, economically viable alternatives are developed. I think if you read up a little on the actual volumes of nuclear waste involved, it's pretty insignificant compared with all the other dodgy stuff we throw into the environment; at least, because of its nature, we have to keep it stored safely.
As for the oil reserves, well, when I was a lad, I remember being told in a lesson that the worlds oil resources would run out in 20 years. That's obviously not happened as additional oil fields have been discovered and methods of extraction have become more efficient. I think current news regarding oil ($60/barrel??) is more to do with political effects, as well as a surge in demand due to economic growth in countries like China, rather than there not being enough there. But I don't know much about these things, I'm sure there are people here much more able to give an accurate, politically unbiased, synopsis of the current situation. Anyway, it still shows the folly of relying on a resource from such a volatile part of the world, so the more we do to lessen our reliance, the better.
