Rosenfeld, winner of the Enrico Fermi Presidential Award in 2006, said the switch from incandescent bulbs became feasible about five years ago when CFL (compact Florescent lights) performance improved.
I think that this is a reasonable move. Energy efficient bulbs are better for the environment and will help save people money. Saving energy will reduce the number of people killed by coal. This measure and copying this measure in other places is not enough. Conservation by itself will not be enough. We also need to get cleaner power sources to replace the coal that we are using. More nuclear power, solar, wind are needed as well as conservation.
