What Is a Wind Energy System?
“Hi, I’m Steve Jones and I’m going to explain what a wind energy system is. Well first of all, wind energy is renewable because wind energy is created by the differences in temperatures of different parts of the earth and this produces a movement of the air which we call wind. Now if we look at a system we all know what a windmill is, we’ve seen windmills, but they’re not always part of an energy system. In the past, windmills have been used for lifting water. They turn wind energy, energy from the sun, into some kind of rotational energy then into mechanical energy lifting water. So you can pump out a wet area for example in Holland typically. Modern systems are true energy systems because what we do is we create energy we can use and the rotation from the windmill goes into a generator and the generator generates electrical energy. The interesting thing about systems is that in the long run, we are looking also to be able to store the energy and here we have an electrical system and
