Y'know, sometimes I think I'm going to scream if I hear another person talking about another "Green" somethingorother. It's getting to be a really annoying thing... kinda like "politically correct" was in the 80's and 90's. I am not a hamster, seems to me that there's a lot more good that can be done by simply doing something sensible and saving some money. I guarantee that people will be much more interested in saving money than in hearing about another "Green" thingummy. A great example of action being worth more than all the catchy-yet-annoying slogans in the world is LED Christmas lights.
LED technology has come a long way over the years and it's now possible to get quite a bit of light out of LED mini lights. LED Christmas lights use anywhere from 80% to 99% less electricity than the traditional incandescent lights. Not only that, but unlike the incandescent bulbs, they don't get hot. Since LED Christmas tree lights only get 1 degree above the ambient temperature (that means if the temperature in the room is 72 degrees, then the lights will run at around 73 degrees). This means that they're not a fire hazard. Another thing is that they last so much longer that it's amazing. LED holiday lights will last for over 50,000 hours compared to only 2,000 hours for incandescent bulbs. That means that the only real reason you'd have for buying more would be to add more lighting since the odds are pretty good you won't be replacing very many of them (if you have to at all, get out one of those aincient LED calculators from the 1970's and fire it up. Odds are very good that all of the digits still work.)
