    Therefore, the switch to low-sulfur coal has likely worsened the North American toxic air pollution problem.

    A pulverized coal-fired power plant will consume about 30-50 percent more fuel than an efficient combined cycle gas plant to produce an equal amount of electricity. As a result, if shale gas displaces coal in the electric power sector, as has been occurring in recent years, then total water consumption per unit of electricity provided will actually decrease – by a lot.
