Here’s a question: when do you expect Australia will be able to produce 25% of its electricity needs from clean energy sources. By 2020? 2030? 2050?

Try 1965. That was the last year Australia produced one quarter of its energy needs from renewable energy. Almost all of it was from Snowy River hydro scheme. The second correct answer could be 2011, but you will have to read below to find out why. It’s not quite as it seems.
