"There is enough wind in the world to supply the entire world’s energy needs. Solar supply exceeds even that by many times and is by far the largest renewable resource. In reality, wind is a second-order effect of solar energy anyway — the sun differentially heats the oceans, atmosphere, and land, and these thermal differences create the wind. This wind, in turn, makes waves; while there is, in fact, a lot of energy in the waves of the deep ocean, there is very little nearer to shore. Even if we captured all of the waves hitting every coastline on the planet, that’s not enough to meet humanity’s demand for energy. The ocean is a fragile ecosystem and capturing large portions of wave energy would negatively affect the oxygenation of the oceans, among other effects."
