Higher efficiencies allow a greater amount of energy to be produced from a single unit of coal. A one percentage point improvement in the efficiency of a conventional pulverised coal combustion plant results in a 2-3% reduction in CO2 emissions. These technologies are in existence, widely available and financially viable.
