Personal transportation is one thing, but the figures for overseas shipping, airplane exhaust, and animal farming constitute well over 30% of total GHG emissions. It's scary. Nevertheless, eliminating fossil fuels in personal transportation (about 13%) is a necessary step.

Another benchmark: Canada's largest province, Ontario, gets 60% of its electricity from nuclear. It has more than twice the population of Denmark, and one-fifth that of France.

EDIT: I misunderstood. I see now you were comparing a nuclear-dominant country with a wind-dominant one.
