Certainly wind has come a long way. Last year, 2009, marked the first year that wind represented the fastest-growing source of new electricity generation. In all of Europe, and in the United States as well, it passed natural gas. So it's certainly a technology that has come into its own; it's very mature. What we find in many jurisdictions is that it is cost-competitive or even cost-preferential relative to what's called conventional generation. In terms of the future of where wind can go, countries such as Denmark right now receive about 22% of all of their electricity from wind. Portugal is at about 13%, Spain about 12%, Germany about 8%.
Canada right now is at about 2%, so there's a great deal more that can be done. It's known that you can integrate at least 20% of wind or other variable sources into your grid, and such sources bring tremendous financial and economic benefits as well. So the sky is the limit.
