Light Bulbs: Shining a Light on Bulb Recycling
We've received several questions about recycling light bulbs, ranging from regular incandescents to compact fluorescents (CFLs). Home Depot Canada is aiming to recycle 1.5 million bulbs by 2011. Lasting six to 10 times longer than the average incandescent bulb and using up to 75 per cent less electricity, CFLs save on power consumption and cut your electricity bill.
The graph shows the market for CFLs.
Suppose the government decides to subsidize CFLs.
Draw the S = MSC - subsidy curve that results in the efficient quantity of lightbulbs. Label it.
Draw a point to show the efficient quantity and the marginal private benefit at this quantity.

Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity. According to one study of these bulbs, a compact bulb that produces as much light as a 100 W incandescent bulb uses only 23.0 W of power. The compact bulb lasts 1.00×104 hours, on the average, and costs $ 11.0 , whereas the incandescent bulb costs only 76.0 ¢, but lasts...
