We went to Lethabo Power station somewhere around Vereeneging for a day tour. I saw many fascinating stuff such as boilers, generators and turbines, it was a great experience for all of us. They said that it took about 10years to build a powerstation and they completed the station in 1990. They use coal for the station because its cheap and it was the nearest coal mine they could find.
Coal is used to burn water which changes into steam, the steam turns the turbine blades, the turbine blades turns the generator then the generates electricity.
