Australia uses about 200 terawatt hours per year.

Snowy puts out (The total installed capacity is 3.772 gigawatts )(5,058,000 hp) but averages less than 1/3 of this.
about 1000 gigawatts.
% of Australias needs- 200,000 gigawatts /1000 gigawatts = 200

So when it is working (no drought) snowy puts out 1/200 of our needs.
Snowy was Australias largest construction project.
So we would need 200 more snowys to meet our needs.
I am not aware of even one site that is similar or as good as Snowy.

Please correct my arithmetic if it is wrong.

Are we suggesting we only run Australia off pumped hydro ?
