Solar energy source

Solar energy comes to us as high intensity radiation (light energy). As it falls on the earth, it is transformed into heat by any superfice or material — be it the atmosphere, soil, buildings, or even the furniture in front of a window. This heat also drives the world's weather systems including wind, rain and river flow. Through photosynthesis, plants also turn solar energy into new growth.

All the energyes except the nuclear energy, comes from the sun radiations.

Difference between renewable energies and non-renewable.

The principal difference is renewables are not spent, however, the non-renewable exhausted and don't last forever, so are the best sources.
