It’s Earth Day and what a beautiful day it is! The weather really showed up today as it is by far the nicest spring day this season. Today Home Depot was handing out a free compact fluorescent light bulb in honor of the glorious occasion. I, of course, ran over to get one while I was out taking care of some errands. (That makes two free bulbs in one weekend including yesterday’s!) I also took an inventory of all the bulbs in the house and what the most used wattage was so I could start replacing them. There are 28 60-Watt bulbs in this house alone! Not including the various other wattage light bulbs, as well as all of the decorative chandeliers and halogen varieties. Wow! I bought three packages of four to start. So today I replaced a total of 14 incandescent light bulbs with energy-saving and carbon-dioxide reducing CFLs. I replaced bulbs in high-traffic, most-frequently used areas to start (ie. the kitchen, bathroom and automated-timer lamps).
To learn more about the differences between incandescents and CFLs, check out some info from Home Depot. With a quick click of a button, I found out that I’ll save $47 per year, that it’ll only take 10 months for the energy savings to pay for the CFLs, that over the lifetime of the bulb I’ll save$634 which could buy me 229 days of electricity. Most importantly, I’ve reduced the amount of carbon dioxide emitted by 1,300 pounds over the lifetime of the bulb.
