A quick and easy way to save a little money by lowering your electric bill and help the environment by reducing the amount of CO2 emissions you’re responsible for is by replacing your normal incandescent bulbs with low-wattage compact fluorescents. Replacing four 60-watt incandescent bulbs with 11-13 watt (60-watt light equivalent) soft-white CFLs can reduce your electricity consumption by 1,500-1,800 kilowatt hours over the life of the bulbs and eliminate up to 2,500 pounds of atmospheric CO2 emissions you would have normally produced using the incandescents. Not only that, but CFLs last on average, 10 times longer than a normal incandescent bulb. Right now, Energy Federation Incorporated is trying to encourage adoption of CFL bulbs by offering those in the U.S. a 4-pack of 60-watt-equivilent CFLs at the amazingly low-price of $11.99 including shipping. Sure, the costs are a little higher up-front, but, over the life of the bulbs you’ll notice a higher return on investment and you’ll be doing a small deed towards helping the environment survive another year, or two (at least!). For readers in other countries, EFLs are certainly available at your local grocery or hardware store or through Amazon, among many other outlets.
