...Lighting accounts for LESS than 20% of my electric costs. Cutting the cost of lighting by even 75%...... would not buy me a cup of coffee at Star Bucks once a month. I think as more people become aware of lighting options (thanks to CFL's) more people will become aware of quality of light, and effective lighting solutions....Yeah the savings from setting back your thermostat a few degrees blows away the savings from switching to CFLs.
Don't get me wrong. You can save money switching to CFLs, if you can stand them.
