(1) An incandescent light bulb produces 5.85 Joules of light energy each second. This bulb is 7.80%
efficient, meaning that only 7.80% the total energy it consumes becomes light and the rest becomes waste
heat. A 12.0 W fluorescent bulb is designed to produce the same illumination (in Joules of light energy
per second) as the incandescent bulb. A large building uses 17,530 light bulbs. At a cost of 8.56€/kW-hr
for electricity, how much money will the owners of the building save each year if they use fluorescent
bulbs instead of incandescent bulbs? Express your answer in dollars. [answer: about $828,000]
