Blow, baby, blow

Now, in the last post, I noted that Germany is going to need other sources of energy (and also they need to become more efficient). Good luck with that.

But the Europeans are trying real hard to build wind generating capacity. I sorely doubt that it will be enough, but it's hard to fault them for trying.

European wind power output tipped to treble by 2020: report

This part is impressive, but how exactly do they get a 3x increase in power generation with less than a doubling of the number of turbines?

"By the end of 2010, there were more than 70,000 turbines in operation, and the EWEA says 60,000 more of the same size would be needed to meet 2020 targets, although installing bigger machines could reduce the number to half or less depending on technology developments."
