In reply to the following question:
Because in the 1980's Germany realised that coal, oil, gas and nuclear energy would be unaffordable by 2020 and they decided to do something about it.
In 1991, they implemented Feed In Tariffs (FITs). At the time the FITs would have been R12 if they had been in the City of Cape Town, whereas Cape Town electricity was 10 cents per kWh in those days.
Germany saw the big picture and created the word's biggest supplier and experts of Renewable Energy equipment. Germany essentially paid for the rest of the world to have cheap electricity!
