Question

1. According to the information on the EERE posting, 22% of the U.S. annual electrical energy consumption is for lighting. The amount of energy is 8.2 Quads, (1.0 Quad = 1015 BTU). This is in agreement with the information given in the International Energy Agency (IEA).

A)What is the energy for lighting, expressed in units of Mboe?

B)If the energy was actually being supplied by oil---it is not, of course--- what would its cost be at the current price level of a barrel of oil?

C)What is the annual cost of the energy for lighting to the rate payers of the electrical energy? (Assume a rate of $0.12/kWh.)

Note: 1.0 Quad = 2.93 x 1011 kWh.

D)Is a saving of 50% of the lighting energy a reasonably achievable goal? Is

it worth the trouble
