Disadvantages of Coal

Coal is the most abundant conventional source of energy which could last for at least 200 years. Coal is an important mineral in India. It occurs as a sedimentary rock in association with carbonaceous shale, sandstone, and fine clay. Coal was formed by the decomposition of large land plants and trees buried under the Earth about 300 million years ago. Sediments began to get deposited over the pile of trees and plants. The resultant heat and pressure resulted in physical and chemical changes leading to the formation of coal. Important disadvantages of coal are discussed below
