Quote:Ok, now for that article on wind power. The USA currently produces 4,156,745,000 MWh of electricity.That's where you go wrong. The article made no claims about the possibilities of providing for a world full of Americans. It was about total current world consumption, and how much that would take. It should be no surprise that if you take only a subset with way above average needs, that this subset would also require more space then average.
You have the same wrong assumptions on overpopulation. Sure, if the world was full of Americans, it would never be able to sustain the amount of people we have now. But as it is, 90% of the world population could vastly improve it's standards of living by getting rid of just the other 10%.
PS.
For the record, if we'd try the same calculation for the Netherlands, we'd need far more 'extra' land (relatively). While our personal ecological footprint is a bit lower, our population density is much higher.
