I think Andrew Kenny should get up to date in his thinking on renewables. In the UK they are now building solar + wind + storage PEAKING plants without subsidy. Compare this to the cost of electricity out of the proposed nuclear plant under construction there. And if you let the ANC build coal plants you end up with a disaster. And if you build gas turbine, at least make them combined cycle and always remember that you need a gas/oil supply contract to go with it, something that Eskom seem to forget!
