Is it now required that I use compact florescent (CFL) bulbs?

No. The new U.S. energy efficiency requirements do not ban the use of incandescent bulbs in your home, nor do they mandate the use of CFL bulbs. However, new energy efficient bulbs like the CFLs, LEDs and Halogen Incandenscents can help you conserve energy, and even help you save money on your energy bills in the long run.
