Week Four--Light Up Your Life with Less Energy

For Week Four of Green Boot Camp, I want you to focus on the lights in your house. That is, I would like you to go through your home, both inside and out, and count how many lamps and light fixtures you have. Once you have this inventory, I'd like for you to go to the store and stock up on compact fluorescent bulbs or CFLs.

CFLs are those twisty light bulbs that are a huge step-up, light-wise, from the flickering, sickly green-casting fluorescent bulbs we all remember from our school days. No, these new CFLs cast light that looks a bit more like the incandescent "hot" bulbs that we are used to and which use a ton of energy. Because unlink incandescent bulbs, CFLs are cool to the touch, use less energy--and last so much longer.

Switching out all of your regular light bulbs for CFLs is one of the easiest things you can do to adopt a more green lifestyle, to make your home more green, and to save money. Oprah just did a show last week on going green, and she couldn't say enough about CFLs. I can vouch for the benefits of CFLs as well.

Last fall I did what I'm suggesting that you do--change all of our light bulbs to CFLs. While we've adopted other energy-saving measures (many of which I will discuss in coming weeks), these new, energy-efficient light bulbs were probably the biggest and most consistent change we made in our home. And you know what? I've watched our electric bill shrink. I'm talking hundreds of dollars of difference each month.

Now I realize that you'll probably spend a bit more upfront in buying CFLs, because they cost more than traditional bulbs. But trust me--your savings will come to you soon enough.

Studies show that CFLs last 10 as long as traditional light bulbs, meaning a bulb you install in your living room today might not need to be replaced until 2012. At the same time, Energy Star says CFLs use up to 75 percent less energy than incandescent bulbs. So, in the long run, you won't have to buy as many light bulbs for your home, and you won't have to pay as much to the electric company for having your lights on because they use so much less energy.

One thing to consider when buying your CFLs: buy them in bulk and in earth-friendly packaging. Too many companies have packaged CFL bulbs in hard-to-open and impossible-to-recycle plastic clam shell packaging. If you're given the choice, choose your bulbs in a paper-based container instead.
