Alternative sources of energy are also known as non-conventional sources of energy which can be recycled or renewed. They are categorised into four types :

(i) Solar Energy

• It is the most widely available and non-exhaustible source of energy.

• It can be trapped using solar collectors and photovoltaic cells.

• In many countries it is being used for cooking and heating purposes.

• Japan, France, Germany and . India are producing this energy.

(ii) Wind Energy

• Wind power has propelled ships as well as driven wind mills to grind grain or pump water.

• Recently wind has been used to generate electricity also.

• The potential for wind energy is tremendous. France and Netherlands have developed this energy.

(iii) Geothermal

• It is the useful conversion of natural energy heat from the interior of the earth to heat buildings and general electricity,

• This energy is developed in Iceland, Italy and United States.

(iv) Hydroelectricity

• The force of falling water is used for generating electricity. It is called hydroelectricity.

• By using turbines, water power has been successfully harnessed which provides power to grain mills, saw mills and other machineries.

• USA, Sweden and Switzerland have developed this energy.
