[a bright idea] Saving energy with lighting
Everyone wants to save energy but did you know that lighting consumes 22% of all electrical power in the United States so it would be a is a good place to get started. I'm not a big fan of compact fluorescent lights (CFL) but I stumbled across the Environmental Lights website that offers CFL's and much more including light emitting diode (LED) lighting which is the use of semiconductors to create light.
From their FAQ's (my emphasis added).
90% of the energy is used to make heat and 10% is used to make light. That’s a lot of waste. Incandescent lights were invented in the 1800’s. Look around your home and office. How much of the technology you use at work and home is over 100 years old? Probably not very much. LED’s, fluorescents and compact fluorescents are much better than incandescents.
