These minerals give us energy and required ignition run factories and motor vehicles. Main power minerals are coal, mineral oil and natural gas.

Out of this coal and mineral oil have special importance the description is as follow :

1. Coal: Coal is the main power mineral. These days the use of coal has decreased. Now it is used in thermal plants for producing electricity. The coal used for this purpose is stone coal. This coal was made in the sedimentary rocks deep inside the earth. It took crores of years in this process. Most of the coal stock in the world is found in 35° to 65° latitude. 90% of world coal is found in China, USA, Russia and European countries. Besides there are large stocks of coal in South America, Africa, North America and Asian sub-continent. Japan and Thailand also have stock of coal.

India produces 5% of coal. Damodar Valley is the main coal-production belt. Madhya Pradesh and West Bengal are coal-rich states.

2. Mineral Oil: It is known as Liquid Gold. Its name has been given because of its use and importance. Its called petroleum or driving force. Because it is extracted from earth like other minerals so it is called mineral oil. It is given the name of petroleum because it is made up of two words— Petra + Olium. Petra stands for rocks and olium means oil. So the literal meaning of Petroleum is oil received from rocks. It is fossil fuel. Most of the Petroleum that we get from inside the earth is in raw form. After refinement of this unrefined raw form, we get many products like Petrol, diesel, kerosene oil, gas, grease, wax, etc.

Most of the oil stock in the world is in South-west Asia, which includes areas like Saudi Arab, Iran, Iraq, Kuwait and United Arab Emirates.
