That gives a rather exaggerated idea of the amount of energy actually available, because a lot of it is already being used, to run things like photosynthesis and atmospheric/hydrospheric circulation.

It's also quite misleading to suggest that winds completely even out over large areas, because there are significant daily & seasonal changes, plus changes due to large-scale weather systems.
