Electrical Energy Systems Current Production Systems: Fossil Fuel Plants -Use coal, natural gas, or oil to heat water -Use steam to turn turbine Nuclear Plants -Use nuclear fission to heat water to steam Renewable Energy Systems -Solar: converts sunlight into heat or electric energy -Wind: Uses wind to turn turbines -Biomass: Use plants and organic matter as fuel. Ex) ethanol from corn. Possible sources in future: willows, algae, crop waste -Geothermal: uses earth heat to turn turbines -oil and gas are the top 3 uses Energy Use -20% of population consumes 78% of natural gas, 65% of oil -U.S. and Canada are only 5% of the population but 25% of total energy use -Rougly 1/3 of energy consumption is for power generation Personal Impact -52% from appliances and lighting -12% from refrigeration -20% from Air Conditioning -10% from Water Heating Current Production in the U.S. -91% of electricity production comes from fossil fuels (oil, gas, coal) -To use these we have to heat water, create steam, turn turbine, discharge hot water or cool and discharge -Byproducts: Warmed water and fossil fuel emissions
