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 Depends on the major power source in your area and how your utility brands itself. Nobody uses "hydro" that way in my neck of the prairies, even if locally there are some hydroelectric dams that are part our power mix.
