Consider a household that uses 14,000 kWh of electricity and 900 gal of fuel oil, per year, during a heating season. The average amount of CO2 produced is 26.4 lbm/gal of fuel oil and 1.54 lbm/kWh of electricity. If this household reduces its oil and electricity usage by 21 percent by implementing some energy conservation measures, determine the reduction in the amount of CO2 emissions by that household per year.

Answer:

9517.2 lbm

Explanation:

Electricity consumption = 14000 kWh/year

Fuel consumption = 900 gal/year

Amount of CO₂ produced per gallon = 26.4 lbm/gal

Amount of CO₂ produced per kWh = 1.54 lbm/kWh

Amount of CO₂ produced in one year

[tex]14000\times 1.54+900\times 26.4=45320\ lbm[/tex]

Reduction would be

[tex]0.21\times 45320=9517.2\ lbm[/tex]

The reduction in the amount of CO₂ produced is 9517.2 lbm
