We destroy our coal fired power stations and pay through the nose for sunny day solar and pray it blows wind turbines. Coal is such a dirty commodity we cannot use it in Australia but we happily export it to any other county to use for power generation. I am so happy to know that the wind obeys a countries sovereignty and the pollution caused stays were the coal is used. Some countries must think we are the dumbest lot of fools, no wonder this country is a failure at manufacturing and being cost competitive.
