Yes, and also all of Tasmania's Hydro generation was built before the whole "green" movement - actually I believe the Australian Green Party started the last time they tried to build a dam in Tasmania in the early 1980's.

Tasmania is also blessed in that Hydro is our "base load" which can be ramped up or down in seconds based on the fluctuating wind and solar generation.

I was driving past some of Tasmania's older dam's today on the way home from a hiking trip and I found myself trying to imagine what the river would have been like if the dam's had never been built. While I am thankful for Tassie's dam's and what they'll mean for our future, it's hard to not notice how much they change the environment.

Car's YES... although I'd say a LOT of people (perhaps most) heat with electricity.
