Change a Bulb and Change the World
is a project to show the difference that a single household (mine!) can make by
adopting energy efficient CFL bulbs, educate people about the benefits of
CFL bulbs in general and help drive the replacement of one million
traditional incandescent light bulbs with energy efficient CFL (compact
fluorescent lamp) bulbs. The goal behind this is to help quickly reduce the
amount of greenhouse gases being generated and reduce our impact on climate
Here's what you should do:
1. Learn what you
need to maximize savings on utility bills
2. Learn where to
shop to find CFL bulbs for all rooms in your house
3. Make a pledge (it's free) to to start using CFL bulbs today.
4. Learn more about
5. Be generous and donate to LittleGreenBulb
What impact would one million new CFL bulbs
have over a year?
1. Save people $13.6 million dollars on their utility bills
2. Prevent the release of 221,000,000 pounds of CO2 greenhouse gas
3. A CO2 (greenhouse gas) reduction equivalent to taking 19,217 cars off
So how big of a difference can you make? It turns out you can make a pretty
big difference. In our home we’ve replaced 44 bulbs and reduced our
electric bill by over 24%. To reach the one million bulb goal, roughly
25,000 homes would need to make a similar level of commitment. Frankly, we
should be able to do much more. Imagine what the impact would be if you
could get a million homes to make the same commitment. Here’s a chart
showing the impact energy efficient CFL bulbs have made on our utility bill.
Notes: We started replacing incandescent bulbs in
February 2007 and continue to replace
the few remaining bulbs (we still have 14 left). We average a 20%
reduction in our utility bill due to CFL bulbs with the peak month of
November showing a 35% savings.
