A coal burning electric generating power plant burns 3 tons of fuel oil to generate 8000kWh of electricity. Calculate the efficiency of the plant as the ratio of electricity output to fuel energy input.
e.g. Convert the tons of fuel oil into kWh
Your room mate leaves a 100W electric light bulb on continuously for one month (30 days). Assume that electricity generation and transmission losses are 40%.
How much electricity was needed to keep the light on?
How much chemical energy in joules was wasted at the power plant for the oversight?
If residential electricity costs $0.11/kWh, what is the cost on your utility bill?
Repeat your answers if a high efficiency light bulb (17W) producing the same luminescence was left on. Compare the costs?
