How alternative power works

Alternative power generated from the alternative sources of energy has been in use for several years. Alternative power resources were used in earlier times for the generation of electricity, grinding of grains and for operating saw mills. The alternative power sources were not fully developed and their potential was not realized until recently. Today the alternative power sources can be efficiently harnessed and can be used for several purposes.

Alternative power works with different alternative power sources. With running water the alternative power is generated in the form of hydro electricity. A dam is constructed and used to control the amount of water that can flow to drive a turbine that is connected to a generator. The rotating turbine powers the generator that can then produce electricity or alternative power.

When the most popular alternative power source, the sun is used, the power generated is called solar power. Solar power can be used for either heating water or keeping buildings warm. It can also be used to generate electricity and to power devices like calculators, watches, cells etc.

When alternative power is generated from wind it is called wind power. The kinetic energy of the wind is used to rotate the blades of turbines that run generators to produce electricity.

Tidal power is not a very popular alternative energy resource. It is harnessed from the low and high tides in the sea. When tides are high water is collected in a reservoir and later used to rotate turbines that generate electricity which can be put to a number of uses.
