Sorting through all the technical jargon and manufacturers’ claims on energy efficient light bulb packaging is enough to make your mind spin. How much energy and money will you really save by swapping incandescent bulbs for compact fluorescents? What about investing in a couple new LED light bulbs? Thanks to the folks over at National Geographic, you can easily calculate the performance of the different bulbs in your home.
For example, let’s say your home has a total of 40 light bulbs (average for a US household). And let’s say that number includes 30 compact fluorescent bulbs, 5 LEDs, and 5 incandescent bulbs. According to the calculator, you’d save over $100 compared to an average home. You can also view the impact if every home used the same number of energy efficient light bulbs: in this example, it would be like shutting down 16 coal power plants or taking 12,435,827 cars off the road.
