You will find no argument here about the problems that arise when corporations are not required to pay for the garbage they produce.

However.

Optimising incandescent lightbulb efficiency is actually not easy to do. It is easy to make a lightbulb that lasts literally forever, if you run it cooler. But if you do that, your power efficiency will be total shit. (And your light will be uncomfortably red, but let’s say that’s less important for now.) You will waste a lot of money on your electricity bill. There will come a point when you will be wasting more money on electricity than the lightbulb is worth. This breakeven point is difficult to determine. It is a calculation that the average consumer shouldn’t be burdened with.
