ANS:Forms of Energy:
(1)COAL:
Coal is one of the major forms of energy.it is formed when buried plants and animals under pressure change into fossil fuel.Coal is used for the production of about 30% of world's power and energy.
(2)Petroleum:
Petroleum is found underground in large quantities deposited in rocks.it is crude oil and a fossil guel formed by decay of dead and living organisms.Big deposite of petroleum are found in USA,Russia,Gulf States and Venezuela.
(3)Natural Gas:
Natural gase is another form of energy .Methane (60-80%) and Ethane(5-9%)are major components of natural gas.It is a cheap source of energy.
(4)Hydroelectric Power:
River water stored in lakes is used as a source of hydroelectric power.Falling water rotates turbines which generate electricity.
(5)Nuclear Energy:
Nuclear power is used for generation of electricity.Nuclear energy is generated through nuclear reactors.In Pakistan this form of electricity is produced by Karachi Nuclear Power Plant(KANUPP) and Chashma Plant.
(6)Solar Energy:
Solar energy is that energy which is obtained from the sunlight.When sunlight strikes certain heavy metals like selenium electrons move and produce electricity.
(7)Wind Energy:
Energy is also obtained from the wing by using wind mills.The Wind rotates generators which produce electricity.
