Oscar helps California fight fluorescent light pollution
2008-06-05 00:56:00 What does Oscar the Grouch, the Sesame Street character who lived in a trash can, have to do with the California Environmental Protection Agency? We discovered at the Sustainable Brands 2008 conference in Monterey that Oscar is helping the California EPA tackle the serious issue of pollution from old fluorescent light bulbs, which contain mercury. California has created a highly innovative ‘Take-It-Back’ Partnership, fronted by Oscar, which is demonstrating the state’s firm commitment to environmental initiatives. For those in Europe who think we are doing so much more than the Americans on the environment, take a look at what California is doing. At the conference, we heard from Leonard Robinson, chief deputy director for the EPA’s Department of Toxic Substances Control. In the video below he is talking to me about the ‘Take-It-Back partnership. http://www.youtube.com/watch?v=-eo9nV5k290Q

CFL (Compact Fluorescent Lights) And Environmental Issues
2008-04-24 15:54:00 CFL (Compact fluorescent lights) bulbs are seen as an environmentally friendly replacement for incandescent lights. But are they really as good for the environment as claimed? The two issues often raised as arguments against using CFL's are1 - It requires more energy to manufacture a CFL than an incandescent lamp.2 - CFL's contain mercury which can potentially end up polluting the environment.The first issue is fairly easily answered in that even though they do require additional energy to manufacture; this is soon offset as CFLs last a lot longer than incandescent bulb.On this issue of mercury pollution I have summarized some of the for and against points of view below:Arguments For CFL'sOverall mercury emission by compact fluorescent lamps is less than the mercury released into the atmosphere by coal-fired power generation for an equivalent incandescent lamp over the same period. This assumption is based on the electricity generated to run lighting in your local area being gene...
Compact Fluorescent Light Bulbs
2008-04-20 21:10:00 I've finally decided to jump on board and try Compact Fluorescent Light Bulbs (CFL) in my new home. Today I bought three GE Energy Smart 20 watt CFL's. The 20 watt CFL is equivalent to a 75 watt incandescent light bulb. These new bulbs are supposed to last 6 years or 10,000 hours of operation. An incandescent light bulb typically only lasts about 750 hours. That means you'd need 14 incandescent bulbs to each fluorescent bulb. The cost of the bulb is payed for just comparing bulbs not even considering the energy savings.Obviously using these bulbs is a great way to start living "green". Some may argue that the Mercury contained in them poses a significant environmental issue, however, with proper education people will realize that they need to be disposed of properly. These bulbs are also energy star certified.I put three of these in an overhead light fixture in our breakfast nook and I was quite impressed. The color of the light has improved drastically and the bulbs come on almo...

Energy Efficient Fluorescent Light Bulbs Have a Dark Secret
2008-03-02 12:57:00 Energy Efficient Fluorescent Light Bulbs Have a Dark Secret: "Here's the latest chapter in the never-ending 'you just can't win' story. Two new reports issued by the state of Maine and the Vermont-based Mercury Policy Project indicate that those righteous, energy-efficient spiral light bulbs endorsed by green organizations can cause mercury poisoning. You have nothing to worry about while the bulbs burn, say the reports -- only if they break, when small amounts of mercury vapor can escape. The report warns that infants, pets, and pregnant women are at particular risk from exposure to the neurotoxin -- although even strapping adults might worry knowing that the researchers measured mercury levels 100 times in excess of federal guidelines for chronic exposure when they shattered 65 of the compact florescent lamps (CFLs). If the proportions hold true, that means that breaking even one bulb will expose you to more than six times the acceptable level."Link
