Alternative power has been in use for several years. Alternative power was used in earlier times for the generation of electricity, grinding grains and to operate saw mills. However, alternative power as a source of energy was not completely developed and its potential was not realised. Today, however, alternative power is an important source of energy that can be put to several uses.
Alternative power works with running water in the form of hydro electricity. A dam is used to control the amount of water that can flow. This flowing water drives a turbine that is connected to a generator. The running turbine starts the generator that produces electricity.
When alternative power is used with sun, it is called solar power. Solar power can be used for heating water or keep buildings or homes warm. Solar power can also be used to generate electricity. It can also be used in devices like calculators, watches, cells etc.
The working of alternative power with wind is called wind power. When wind blows, the kinetic energy of the wind is used to rotate the blades of turbines. This movement results in running of turbines inside generators to produce electricity.
With tides, alternative power is called tidal power. When tides rise, water is collected and later used to rotate turbines. The turbines generate electricity which can be put to a number of uses.
Alternative power is becoming more and more popular as it is environment friendly and keeps the water and air clean and pollution free.
