The Truth About Windmill Electricity! Here is Something Most of You Do Not Even Realize

Humans have harnessed the energy of the wind for years together now. Initially they were using the wind to pump water through primitive irrigation systems or to grind grain. Today's turbines have evolved so much that they consume wind energy to rotate huge metal blades which results in the spinning of generator thus producing electricity.

Windmill electricity turbines are supported on very tall towers in order to acquire the maximum wind energy available. At close to 100 feet or much higher than the ground, these turbines make maximum use of the speed of the winds in order to yield electricity.

A blade behaves similar to the wing of an airplane. Upon the winds falling onto the blades, a low pressure pocket is formed at the blade's bottom side. This change in pressure causes the rotor to rotate. This force is termed as lift and is immense compared to the force of the wind touching the front of the blade. This is termed as drag. The amalgamation of drag and lift makes the rotor to roll and the rotating shaft turns a generator to produce windmill electricity.

In recent years, enormous amount of interest is being shown towards windmill electricity as the next possible substitute after fossil fuels. The only problem with wind power is that it is unreliable. When the wind stops, the generation of power also stops. This means that entire wind farms could go out of operation for months thus affecting many industries, factories and households.

Small windmill electricity systems have the ability of energy reserves that are distributed. These energy supplies refer to modular technologies that generate power and can be pooled to enhance the performance of the delivery system of the power generated.

Imagine, if every house had its own small windmill, we could save so much and reduce our dependence on fossil fuels to generate windmill electricity.
