How many Liberals does it take to change all of the Light Bulbs?

Legislator Wants Green Lights in California

A California lawmaker wants to ban the use of incandescent light bulbs in order to conserve energy and reduce greenhouse gases which are linked to global warming. Instead, compact fluorescent light bulbs (COLS) would become the alternative for California residents.

This is a noble idea that responds to the fact that fluorescents consume far less energy and generate far less heat than incandescents. A significant percentage of US energy use is for lighting and by changing our bulbs we can offset the building of some power plants.

However it seems to me that this is a good example of how a progressive ambition could be better implemented with conservative methods. Instead of banning incandescents simply tax them to close the gap between their price and that of COLS. Let purchasers decide if they are willing to pay the premium in energy costs for the special quality of light that many attribute to Incandescents. Why use draconian methods when more flexible approaches achieve almost the same results?
