This month's lightbulb wars going on over at Re-Nest got me thinking about whether or not dimmer switches save energy. In the past, the electricity from the unused energy was converted to heat at the switch, but is that still the case?I have to admit, this post might resolve an ongoing turn-off-the-lights/why-can't-I-leave-them-on-dimmed debate that has been ongoing in my household because dimmer switches DO indeed save electricity. If you have the newer dimmer switches, they now include a "Triac Switch" which cuts the flow of energy to the light. It causes a constant flicker which the human eye cannot register, cutting down on the actual electricity used to power the light. The best news is that if you use the dimmer switch at about 50% you will save money on your electric bill in the long run!
