Re: A tax on lightbulbs.

You have to be a little careful in your assumptions of energy conservation. When a normal bulb uses energy it transfers it into both light and heat. the percentage of each I don't know but it is significantly biased towards heat!, likewise with a energy saver, there is light and heat although significantly less of the latter hence teh input requirement is much less.
