What matters, from a public policy perspective, isn’t any given choice but the total amount of electricity I use (which is itself only a proxy for the total emissions caused by generating that electricity). If they’re really interested in environmental quality, policy makers shouldn’t care how households get to that total. They should just raise the price of electricity, through taxes or higher rates, to discourage using it.
Instead, the law raises the price of light bulbs, but not the price of using them. In fact, its supporters loudly proclaim that the new bulbs will cost less to use. If true, the savings could encourage people to keep the lights on longer.
Even if you care nothing about individual freedom or aesthetic pleasure, this ham-handed approach wouldn’t pass muster in a classroom at Harvard’s Kennedy School of Government. As pollution control, it’s horribly inefficient.
