Coal Burning

We generally think of sulfur emissions and acid rain when we think of coal-burning power plants. However, several other environmental problems are associated with coal burning. Could someone help me describe three of them.

A coal-fired power plant produces a net electrical output of 500 MW.

3. A coal-fired power plant produces a net electrical output of 500 MW. The composition of the coal burned is C = 72%, H = 5%, S = 2%, O = 8%, N = 1%, and ash = 12% by weight. Its higher heating value (HV) is 30,940 kJ/kg. The net thermal efficiency is 33 percent. a) How much coal (in metric tons) does this plant consume in one
