Sun is the source of all forms of energy including fossil fuels which are mostly stored below the ground are polluting and other ill effects.
Renewables are directly from Sun, mostly solar(Electric) and thermal which are used. As these are becoming cheaper these are used and continue to be used with increasing content apart from other sources. Tropical countries have some advantages due to higher solar insolation which should be taken full advantage, I think.
