How much energy does old garage door use.
Running the opener for twenty seconds or so ten times a day won t use as much energy as leaving a 100 watt light bulb on all day.
So one cycle open or close consumes 343 watts for 10 seconds comes out to be 57 watt minutes 95 watt hours.
Considering you ll probably only use your opener a couple minutes each day this power consumption is fairly negligible.
