  • Nuclear Energy ProductionAlthough the national percentage of nuclear generated electricity is 19%, it varies from state to state.

  • U.S. Primary Energy Consumption

  • U.S. Electricity FlowConversions and Losses25.81 Btu or 63.4 %

  • U.S. Capacity Brought Online by Fuel Type

  • Fifteen Ways to Stabilize CO2 EmissionsOf the 15 methods (wedges) proposed by a Princeton University study,13 of them relate energy use. Implementation of any 7 wouldaccomplish the goal of stabilizing emissions. 1. Efficient vehicles 2. Reduced use of vehicles 3. Efficient buildings 4. Efficient coal power plants 5. Gas instead of coal power plants 6. Capture CO2 at base load power plant 7. Nuclear power for coal power 8. Wind power for coal power 9. Photovoltaic power for coal power 10. Capture CO2 at H2 plant 11. Capture CO2 at coal-to-synfuels plant 12. Wind H2 in fuel-cell car for gasoline in hybrid car 13. Biomass fuel for fossil fuel
