How do you suppose existing solar farms store energy?
Judging by this:

9.6 billion USD would have got us a solar farm with 9600 MW cap.
R154 billion Rand. Theres spare change for expansion and extra storage and we could have boasted the biggest solar farm in the world. Instead we have the biggest coal power station in the world. Yay.
Regardless, by switching to solar or other renewables we will, as a species, be forced to plan better and use electricity more sparingly or more efficiently (planned storage e.g. heating a building before peak demand and storing that energy... improving insulation). IMO that contributes enormously to sustainability than the alternative of throwing another piece of coal on the barbie.
450-500 BILLION would have got us something nice and something to be proud of... as it is, all it got us is a big bloody furnace.
