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?
