Why south africa must include renewable energy in its energy mix 3 reasons

All things considered, here's the reason. 
Non-renewable energy sources are exhausting as a few of us know and that implies we can't depend on Eskom until the end of time. What's more, with sustainable power source organizations, for example, Groundbreaking Vitality ascending, it won't be long now before you see turbines in your terrace. 
The drawback is that South Africa still owes a huge number of dollars to the world bank and most likely we can all observe that the dept is not getting paid at whatever time soon, to which I say that we ought to assemble water factories, supply ourselves with sun powered boards and turbines while individuals are pursuing down Zuma.
