According to the BP statistical review the US primary energy consumption in 2014 was 2300 mtoe (million tons of oils equivalent). Oil has an energy density of 42 MJ/kg.
(a) What is the US energy consumption in Joules. What would be a better unit (MJ, GJ, TJ, PJ, EJ)?
(b) What is it in quads (1015 BTU's)?
(c) What is it in kWh ? What would be a better unit (MWh, GWh, TWh, PWh)?
(d) Uranium ore is 0.07% 235U. If 235U has an energy density of 1.28 x 108 MJ/kg what is the mass of Uranium in Uranium ore that would give the same primary energy?
(e) What is the average power used?
