Canadiana question: is "hydro" a blanket term for "electricity"?

I just read a Globe and Mail story that referred to windmills -- the things that are spun by the wind -- as "hydro windmills."

I can imagine how all this started but I gotta say it's really confusing seeing a term that literally means "water" being used for things that are not water. Would a Canadian say "hydro coal"?

@rwg ... nuclear hydro ... no. In Alberta now we never talk about hydro, but when we lived in Toronto we'd talk about the hydro bill certainly; I think we'd just say the power's out, though, not the hydro's out
