the energy conversion is about 33%. About 1/3 of the coal's chemical energy is converted to electric energy. The remaining 2/3 of the energy is rejected to the environment via cooling water evaporated as low-grade waste heat with poor thermodynamic availability. The waste heat comes from evaporation of cooling water after it is used to condense the highly purified, low temperature steam that exits the turbines after driving the electric power generator. The condensed steam is then recirculated (pumped) back to the high pressure boiler for re-use. Other steam generating (nuclear, gas, coal, geothermal, and solar furnace) energy centers, like Jeffrey, operate their steam plant on the Rankine cycle. According to Moyers and Company web site as of September 18, 2013 Jeffrey EC ranked 12th of the 50 dirtiest American power plants and generated 14.7 million metric tons of carbon dioxide emissions in 2011.
