COAL RESERVE IN PAKISTANENERGY CONSUMPTION IN PAKISTAN Primary Energy Consumption by Source in 2009-2010INTRODUCTIONTO THAR COALCoal is a cheap indigenous energy resource and, after the discovery of175.5 billion tonnes of coal in Thar area of Sindh,Pakistans coal poer potential has increased !anifold."t is anticipated that, if properly e#ploited, Pakistans coalresources !ay generate !ore than 1$$,$$$ %& ofelectricity for the ne#t '$ years.COALRESERVESINMILLIONTONNESIN FOURBLOCKOFTHARCOALFIELDPotential of the oal185 billion tons of coal reserves are present in different regions of the country.Almost 95% of coal is undeveloped in Pakistan, only 5% coal is developed.Pakistan consumes 1% of coal per year for production of energy in different po!er plants. "# coal fields are present in different regions of country $har is the biggest of all and this is still undeveloped.$har has 1%5 billions tonnes of coal reservior deposits!HAT IS GASIFIER"
