Sometimes the powers that be have to make people do things that they don't want to do. Like...seat belts. And motorcycle helmets. Well, that one didn't go over so well. Don't get me started. One of the more recent actions that will affect all of us is the phasing out of incandescent light bulbs.
We already use CFL's but recently took advantage of Duke's free offer.
Even if you aren't on Duke energy, you might refer to the website to learn more about why CFLs are a good idea. After all, it is for your own good! (And isn't free an enticing word?)
