Hmm, that site seems to be a mixture of apparently real statistics and pure doom-mongering (as you would expect from a site called Exit Mundi!). It's like reading the front page of The Daily Mail.
"Take wind energy. Wind is obviously stuff that doesn’t contain a lot of energy -- just compare slamming your head into a bit of wind with slamming it into a concrete wall. And what’s more: to build wind mills, you’ll have to weld steel, drive all kinds of stuff and engineers around in trucks and cars, build factories and make thousands of components. In the end, it costs more energy (oil) to actually build a windmill, than a windmill will ever generate during its entire lifetime!"
This, for instance, is obviously a load of bollocks! The scientific method he employs to show us how ineffective wind energy is to... bang our head against wind. Yes. Right. And his/her (gotta be a guy, surely?) assertion that wind farms will actually never produce more energy than it took to make them... well, it’s unbelievable that anyone could write that with a straight face! And I suspect that he probably didn’t.
But, anyway, thanks for the heads up, there was some interesting stuff.
