(Pg. 162-175). Sections 5.1-5.3; Vesilind & Morgan Ch 6. (Pg. 117-129)Overarching Questions: Power Plant EmissionsHow much energy is used by humans each year? USA residents? Where does this energy come from? What sources of energy are used for electricity production? How is the relative distribution different from that for total energy?Which countries emit the most CO2to the atmosphere?What trends exist with respect to overall use of electricity? What are typical yearly emissions from all USA power plants? How are such emissions calculated as a function of fuel source?
