Assume that in 2010 the United States will need 2.0×1012 watts of electric power produced by thousands of 1000 MW power plants. These will almost certainly be powered by either coal or nuclear reactors. If all the energy is provided by U-235 burning reactors, how many tonnes of U-235 will be needed annually? NOTE: Rather than using the exact energy from problem 1, please assume that fission of U-235 releases a "rounded" 8.E13 J/kg (Assume a realistic efficiency of 45...

The average US citizen consumes 12000 kWh of electric energy per year an ‘ end use’ number and does not include the energy lost in converting other energy sources, e.g. fossil fuels to electricity. Note also that a kWh (kilowatt hour) is a unit of energy (not power) but a ‘kWh per year’ is a unit of power. The average electric bill indicates that a consumer pays about $0.12 per kWh of electric energy. Your Uncle Joe wants to get...
