How should I answer question 3???

Free Response Question 1: West Fremont is a community consisting of 3,000 homes. A small coal-burning power plant currently supplies electricity for the town. The capacity of the power plant is 12 megawatts (MW) and the average household consumes 8,000 kilowatt hours (kWh) of electrical energy each year. The price paid to the electric utility by West Fremont residents for this energy is $0.10 per kWh. The town leaders are considering a plan, the West Fremont Wind Project (WFWP), to generate their own electricity using 10 wind turbines that would be located on the wooded ridges surrounding the town. Each wind turbine would have a capacity of 1.2 MW and each would cost the town $3 million to purchase, finance, and operate for 25 years.

1.Assuming that the existing power plant can operate at full capacity for 8,000 hrs/yr, how many kWh of electricity can be produced by the plant in a year?

12mw x (1000 kwh) x (8000 hrs) =(9.6x10^7 kwh/yr)

(1mw)(yr)

2.At the current rate of electrical energy use per household, how many kWh of electrical energy does the community consume in one year?

(3000 homes) x (8000 kwh)= 24,000,000 kwh/yr= (2.4x10^7 kwh/yr)

(yr)

3.Compare your answers in (a) and (b) and explain why you would or would not expect the numbers to be the same.
