We have got two nuclear power stations and we have some hydro power as well. If we look at the future it is unlikely that we will only use coal again in the pulverized fuel form due to the involved CO 2 emissions. The long lead times are also problems. The huge capital investment required for a 4000 MW power station is also a problem. But then we are also looking at renewables.
Wind is a possibility.
South Africa's wind situation is not very well suited for power generation. Of course, it is very expensive compared to our other generating possibilities. South Africa has got some of the best solar energy possibilities in the world. We have looked at solar thermal. Also you can actually delay the capital investment for power stations by adopting photovoltaics.
