I remember my college desktop and how happy I was when I got a 400W power supply! Now the Mac I travel with that has 100x the processing, storage, etc uses a 85W supply if it's plugged it. If you do that at scale with more efficient everything, it makes sense. Remember when turning off the lights saved money? It was dubious then but with bulbs that use 1/10 the power, it's almost humorous.

Ya, that 8 watt LED bulb will cost you $8/year running 24/7 at 10cents/kwh. If it takes 2 seconds to turn it on and off each day, that's 24 minutes a year saved by leaving it on. If your time is worth >$20/hr, consider uninstalling the switch.

  And in Austin, energy rates are 1/3 of that. If your light is on 1/3 of the time, we're down to < $1/year. Without any time/value aspects, saving $1/year isn't on anyone's radar.. especially since the AC turning on is going to be much more.

    > And in Austin, energy rates are 1/3 of that. Are you saying electricity delivered to the home costs 3 cents/kWh in Austin? I flat out don't believe that. We're paying over 20 cents on Cape Cod. I can believe 10 cents in some areas. 3 cents, sorry; no.

      As of December, the Austin Energy rates are 2.8c/kWh at the bottom tier, ranging up to 10.8c/kWh at the top. Once you add all the extra fees and "one time charges" that happen every month, it's more but that's the base.
