Renewable energy is derived form natural resources that are replenished at a faster rate than they are consumed, and thus cannot be depleted. Solar, wind, geothermal, hydro, and some forms of biomass are common sources of renewable energy. Almost 90% of the globally existing PV capacity was installed during the last five years alone. South Africa has an Integrated Resource Plan that integrates the power generation mix until 2030.
