18-30. greenhouse gas reduction. an 18-w compact fluorescent bulb produces approximately the same amount of light as a 75-w incandescent bulb that screws into the same socket. the fluorescent bulb lasts 10 000 h and the incandescent bulb lasts 750 h. over the lifetime of the fluorescent bulb, the electricity savings is (75 18 w) (104 h) 570 kw h. one kilogram of coal produces 2 kw h of electricity. if coal contains 60 wt% carbon, how many more kilograms of co2 are produced by running the incandescent bulb rather than the fluorescent bulb? if the coal contains 2 wt% sulfur, how many more kilograms of so2 are produced?
