Tilting at Windfarms
The other scientific thing that caught my eye over the weekend was a very well-written post over on Black Sun Journal about global warming and the future of energy use.
I have to admit that I am instinctively a bit of a global warming sceptic. On the one hand, I've always worried about using up resources of the earth that took millions of years to create - seems a bit reckless. On the other hand, I hate bandwagons and I dislike the fact that it is now socially unacceptable to question global warming as a fact, or the effectiveness of alternative energy sources.
So a good, well-reasoned argument in favour of the case for alternative energy production is very welcome, in this corner of the pond. Sean makes a good case for wind energy, for example. The only thing I wonder about is if wind energy was widely used throughout the world, surely weather patterns would be affected? If the wind is being turned into energy instead of powering its way round the world, it must have an effect. Anyone got any answers?
I like the sound of the halogen replacement bulb though and will certainly give them a go when they come down in price. It's the disposal of all our stuff that I think is as important as the energy itself and silicon sounds a lot better than mercury.
Right, that's enough clever stuff - my brain hurts. As an antidote, xkcd, as usal, has the answer...
