Generate Cheap Energy From The Wind

A wind turbine is a machine which turns the kinetic energy from the wind by catching it with its blades into mechanical energy by its spinning. The mechanical energy from its spinning turbine is then converted into electrical energy for consumption. This can be used in a large scale like the wind turbines of Denmark, or small scale for buildings and houses.

Wind energy is a type of solar energy; it is caused by the heat from the sun, spinning of the Earth and the irregularities of its land. This makes a wind turbine generator one of the best utility sources there is. It produces no pollution, very little noise (a household wind turbine generator just makes as much noise as a washing machine) and is very cheap to build. A wind turbine works the opposite way of a fan. A fan uses electricity to rotate its blades and create a wind flow; a wind turbine generator on the other hand catches the wind to rotate its blades and converts the mechanical energy into electricity.

A wind turbine generator has three parts, the blade, a shaft that connects the blade to the third part, a generator. When the blade rotates, this would spin the shaft and make the generator work. A wind turbine generator for a house needs about 300 RPMs from the generator to produce enough electricity to save about ninety percent of electricity costs. Basically, a larger and taller wind turbine is more effective because the higher it goes, the better the wind flow.
