Save about $700 million in annual energy costs. Save enough energy to light more than 3 million homes. 1000 Prevent 9 billion pounds of greenhouse gas emissions per year. Fun Fact: The oldest lightbulb The world's oldest bulb that has been burning since 1901, or nearly one million hours so far. It took Thomas Edison roughly 10,000 tries until he got a stable, working version of the incandescent bulb. lightbulb is Incandescent STANDARDS USED 6 Twenty-Five year old pine trees absorb 1 tonne of CO2", 1.54 Ibs of CO2 per kWh SOURCES 1. http://www.ehow.com/about_5306554_halogen-bulb-lifespan.html 2. http://www.p2pays.org/ref/26/25978.pdf 3. http://www.energystar.gov/ia/products/downloads/CFL_PRG.pdf 4. http://www.erasecarbonfootprint.com/treeoffset.html WellHome. 5. http://www.snopes.com/science/lightbulb.asp 6.7. http://inventors.about.com/library/inventors/bledison.htm 0.
