How Much Money Can You Save by Switching to Energy-Efficient Light Bulbs?
Incandescent light bulbs had a good run, but with the Energy Independence and Security Act (EISA) of 2007 now in its final phase, you’ll probably begin to notice that it’s getting harder and harder to find traditional incandescent light bulbs in stores.
In a nutshell, EISA has taken a three year approach to converting the United States to energy-efficient lights by prohibiting the manufacturing or importing of non-compliant incandescent light bulbs.
- January 2012 – 100-watt bulbs banned
- January 2013 – 75-watt bulbs banned
- January 2014 – by year end this year 60- and 40-watt bulbs will be banned
You might still see some of these bulbs on store shelves as it isn’t illegal to sell current or leftover inventory, but over time they will all disappear. But that’s not a bad thing. In fact, it will help American save a lot of energy and money.
How much can you save by switching your household
to energy-efficient bulbs? Well, let’s take a look. We need three things to determine the cost of light usage and the potential for savings when switching to energy-efficient lighting:
- Amount of electricity used Cost of the electricity Time the lights are turned on
Amount of Electricity Used
We’ll need to begin with the amount of light bulbs in a home. According to a recent survey, the average American household uses 47 light bulbs .
Now, these bulbs might have varying wattages from 100 watts down to 25, but for the sake of easy math and comparisons, let’s assume that we are using all 60 watt bulbs.
Total Light Wattage = 47 bulbs X 60 watts = 2,820 watts
That’s a lot of wattage! Now let’s take a look at the wattage if all 47 lights are CFL bulbs or LED bulbs at the equivalent brightness of 60 watt incandescent bulbs.
