The only problem I have with this story is the ending of the lead. The author states as a know fact that global warming is human caused rather than a belief. The rest of the article is factual and to the point. He does caution that LED lighting like other technologies that substitute for the candle or whale oil comes with its own set of problems and features that people will have to get used to.
The article presents useful information about the advantages as well as the difficulties of using LEDs as a source of residential and business lighting as well as placing it in the broader context of energy usage.
A good technical direction to know about with regard to reducing energy consumption. LEDs have been around for a long time, this is a good update on how they are progressing as an alternative.
