More on off-shore wind

Treehugger makes the argument for off-shore wind. I've talked before about off-shore wind and Treehugger capture the essence of the argument perfectly.
"Most campaigns against turbines are based around the noise and the visual impact, and these have been reduced by going offshore. It is more expensive to do it here than to do it on land"

I could campaign against coal saying that it is dirty, polluting, and kills (depending on how you calculate it) perhaps several and perhaps dozens of people each year. But somehow coal remains cheap and wind power is forced to be expensive by going off-shore.
