Coal is the dominating force in power generation. At least 27 percent of the world's total energy output and more than 39 percent of all electricity is produced by coal-fired power plants due to coal's abundance, its relatively easy and low-cost extraction, and less expensive infrastructure requirements compared to other energy resources.

nearer to that of the coal calorific value. It is observed that Indian coal is having highest CV and the briquettes P WO100,P W100, P W20, are nearer to that of the coal calorific value. 5.
