Electricity was invented during the industrial revolution. Electricity is used for industrial purpose and that for domestic purposes. At industrial level, it is used to run the industries, machines, transportation, etc. At domestic level it is used for running various household gadgets like fans, televisions, radios, washing machines, refrigerators, tube lights, etc.
There are mainly three forms of electricity. They are:
- Thermal electricity,
- Hydroelectricity and
- Nuclear electricity.
Coal, mineral oil, natural gas, etc are conventional sources of producing electricity. Electricity produced through flowing water or rivers and dams is an example of hydroelectricity whereas electricity produced through atomic minerals is an example of nuclear electricity. Minerals are scarce in comparison to their usage. Hence, it is extremely important to switch to non-conventional sources of energy like solar energy, wind energy, tidal energy and geothermal energy to produce power.
