The strongest source of energy in terms of Energy density (Energy per unit volume) of all the renewable sources is Biomass. Wind is a concentrated form of Solar Energy. Waves are concentrated forms of Wind Energy. There is much more energy in the sunlight that strikes the Earth than in the winds that blow.
solar radiation The sun heats the surface of the Earth unevenly. The warm air expands, becomes less dense and rises. Cold air condenses and sinks. The cold air moves across the surface of the Earth to take the place of the rising warm air. This is wind.
The Sun is the primary source of all energy on Earth.
