What is Wind Energy?
For us though, it consists of the bulk movement of air. They are commonly classified by their spatial scale, their speed, the type of forces that cause them, the regions in which they occur, and their effect.
To mention some; gust which is a sudden, brief increase in speed at least 16 knots and duration less than 20 seconds. Strong winds of intermediate duration (around one minute) are called squalls. Breeze, gale, storm, hurricane and typhoon are of long-duration and with different average strength.
A constant breeze from Noth-East
On the Caribbean island of Aruba where we live, we have a constant breeze coming in from the North-East with an average speed per year of 14mph. Indeed good as wind power for homes. Because of this constant one-sided wind power energy, our Divi-divi trees take the shape like on the picture above, growing in the wind direction. We are blessed with constant sun and wind on a daily basis.
Wind power is harnessed to drive wind power generators for the production of electricity or to drive windmills which is used in different ways to do mechanical work such as grinding of whole corn to make flour in agriculture and as lumber cutter. There may be other ways to transform the rotational movement of a windmill to produce other type of work. It all depends on one's imagination.
Wind power energy is a clean and renewable type of energy, but like solar- and geothermal energy there are moments of reduced capacity due to natural influences and we have to provide for those moments. The use of wind as one of our alternative energy sources does not produce pollution and thus contributes to our ecological environment.
