As far as I know, there isn’t one in the works yet. However, there is a ban on incandescent bulbs to take effect by 2014. I suspect the reason why no one is trying to ban candles, oil lamps or gas lights is that they aren’t very widely used and so legislative prohibition is not needed. Incandescent lamps are popular and so a legal prohibition would be necessary to make them go away.
This isn’t just a matter of gross inefficiency and messing with the free market in light bulbs. It’s yet another example of arbitrary imposition by mostly unaccountable people in government and regulatory agencies. This approach is as un-American in spirit as it is traditional in practice — this kind of imposition has been around since 19th century at least and probably longer. Might be a good time to do something about it.
