Electricity From The Wind
Understand the wind Tapping the energy in wind is a hitand-miss proposition without first understanding the nature of wind. Windplant installers or owners will make critical errors in selection, siting, and use without this knowledge.
Wind is born from the unequal heating of the earth’s surface and oceans by solar energy. Wind is, simply enough, a moving mass of air. What air lacks in density it more than makes up for in speed. Put a windturbine in its flow and the wind will spin it. In effect, the wind machine is “gathering” some of the wind’s energy. It must not take it all.
Observations and calculations predict that only 60% of the wind’s energy can be extracted without adversely affecting performance. So, enough energy must be left in the wind to allow it to move on.
To the casual observer, there may seem to be little pattern to the wind. However, in years of data measurement and recording at airports and climatological stations, distinct patterns have emerged in both wind direction and velocities. Annual, monthly, and even weekly patterns exist
