Carbon Cap And Trade. The talk is always about the political point of view. We are told that coal fired power plants are the largest emitters of Carbon Dioxide. If there is a correct understanding of the way those coal fired power plants produce their electrical power, and the way that consumers use that power, then it becomes obvious that Cap And Trade is only in place as a revenue raiser, and can not actually lower Carbon Dioxide Emissions. A new Tax cannot lower emissions of itself.
