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.

    reduction in the amount of CO₂ emissions by that household per year is 9517.2 lbm per year

    Explanation:

    given data

    electricity consume = 14000 kWh

    fuel consume = 900 gal

    CO₂ produced of fuel = 26.4 lbm/gal

    CO₂ produced of electricity = 1.54 lbm/kWh

    oil and electricity usage = 21 percent

    to find out

    the reduction in the amount of CO₂ emissions

    solution

    we calculate the amount of CO₂ produce here that is

    amount of CO₂ produce = (electricity consume*CO₂ produce electricity + fuel consume * CO₂ consume fuel) ... 1

    put here value

    amount of CO₂ produce = (14000 * 1.54 + 900 * 26.4)

    amount of CO₂ produce = 45320 lbm/yr

    we know reduction is 21%

    so

    reduction in amount of CO₂ produced is

    reduction in CO₂ produced = 45320 * 21%

    reduction in CO₂ produced = 9517.2 lbm per year

    so reduction in the amount of CO₂ emissions by that household per year is 9517.2 lbm per year
