Basics of Wind Energy

To understand how wind energy works, we must first of all, understand the daily wind cycle.

During the day when the sun is out, the air over the land heats up faster than the air over the ocean. This heated air is lighter and therefore rises. The cooler air is denser and falls. The rising and falling of air creates convection currents.

During the night, it is the opposite. The air over the ocean maintains heat longer than the air over the land. The air over the ocean now rises and the air over the land falls.

This air that moves carries a lot of energy with it.
