Demand for energy means coal will remain a part of the mixture of fuels. Coal and other fossil fuels will be needed for the increasing deamand of alternative energy. Coal and other fossil fuels are still vital for the survival of this industrialized society. We still need oil, natural gas, and coal, for vehicles and power plants. Mark Smith said that we need all energy sources, not just solar or wind. The country will need to be increasingly energy efficient and away from higher polluting fuels. It seems as if coal will remain an essential part of our society, even though many people are trying to become more energy efficient. Personally, I feel we should continue to use fossil fuels, as we will outlast our need for fossil fuel, yet it's very interesting that people are talking about coal remaing as a source of energy.
