Question

30 PTS, SHOW YOUR WORK How much carbon dioxide will you prevent from entering the atmosphere in one year, if you replace a 100-watt light bulb with a CFL bulb that uses 30 watts in a fixture that you have on 8 hours per day? (round to the hundredths place)
(1.37 pounds of CO2 per kWh)

Answer 1

The amount of carbon dioxide will you prevent from entering the atmosphere in one year is 280028 lb

How much carbon dioxide will you prevent from entering the atmosphere in one year?

We are given 1.37 pounds of carbon dioxide per kWh

Using a 100-watt light bulb daily for 8 hours, for a year, the amount of carbon dioxide produced will be:

100 × 1.37 × 8 ×365 = 400040 lb

Using a 30-watt CFL bulb for 8hrs/ day for a year, the amount of carbon dioxide produced will be:

30× 1.37 × 8 × 365 = 120012 lb

Therefore, carbon dioxide prevented:

= 400040-120012

= 280028 lb
