A certain region currently has wind farms capable of generatinga total of 2100 megawatts ?(2.1 ?gigawatts) of power. Completeparts? (a) and? (b) below.
a. Assuming wind farms typically generate 25?% of their?capacity, how much? energy, in? kilowatt-hours, can the? region'swind farms generate in one? year? Given that the average householdin the region uses about? 10,000 kilowatt-hours of energy each?year, how many households can be powered by these wind? farms? Thewind farms can generate nothing ?kilowatt-hours in one year.?(Simplify your? answer.) The wind farms can power nothinghouseholds. ?(Simplify your? answer.)
b. One of the great advantages of wind power is that it does notproduce the carbon dioxide emissions that contribute to globalwarming. On? average, energy produced from fossil fuels generatesabout 1.5 pounds of carbon dioxide for every? kilowatt-hour ofenergy. Suppose the region did not have its wind farms and theenergy were instead produced from fossil fuels. How much morecarbon dioxide would be entering the atmosphere each? year? nothinglbs ?(Simplify your? answer.)
