Many countries around the world are already using wind energy systems in large numbers. In order to understand the impact that wind energy can have on our future, it is important to know how it is generated. Here is a look at the wind energy generation process.
1. The wind turbine blades start to rotate with the action of the wind on them.
2. The spinning of the blade cause a shaft inside the gearbox at the top of turbine to rotate.
3. The shaft is connected to a gearbox which in turn starts rotating with increasing speed.
4. The rotational energy is converted into electrical energy by a generator. This is achieved with the use of magnetic fields.
5. The electricity from the wind turbines reaches the transformer which converts it to the correct voltage for the distribution system.
6. The power is then ready to be supplied to consumers and is distributed from the power grid.
This is the basic process used for obtaining electricity from wind energy systems. Two types of turbines are used: two-blade and three-blade. A two-blade turbine faces away from the wind and a three-blade turbine faces into the wind.
People thinking of using small turbines for their homes should keep in mind, that it’s highly unlikely that they could power your entire house with less than a dozen turbines. The best solution is to use the turbines, but also remain connected with the power grid and make use of solar energy also through the use of solar panels which you can also make yourself.
Then when there is no wind or the wind turbine is not supplying enough electricity you can switch to the power coming from the grid.
Wind turbines were originally used to grind corn. But, the work done in wind energy development has enabled us to harness the energy of the wind to provide electricity and protect our environment from pollutants.
