Current energystar models use only 30 60watts for a 40 tv so those 4 hours asleep cost you about 2 cents.
How much energy does old garage door use.
I ve found very little information lots about their light bulbs though but another yahoo.
Refrigerators built prior to 1993 could use as much as 3 times the energy than a newer energy star certified fridge.
If your home has a garage there is a good chance that you have an automatic garage door opener.
A garage door opener has a radio receiver garage lights and a motor to lift the garage door.
It takes say 10 seconds to open or close.
Door from a dead stop.
This gives it around 1 100 to 1 400 starting watts and 550 to 725 running watts.
Considering you ll probably only use your opener a couple minutes each day this power consumption is fairly negligible.
That doesn t sound too terrible.
I ve been looking for information about garage door openers and their wattage.
My personal experience is 5 10 a month cost to run my garage refrigerator and she s an old beast.
The variance of external temperature.
Doesn t seem like such a minor thing anymore does it.
It s opened with a 1 2hp induction motor.
Uses 445 watts while opening or closing the door including the 108 watts used to power the light bulbs.
On the other hand it will have a substantial impact on the overall energy wasted for the building that has the automatic door open button.
The amount of energy that a garage door opener uses is very small.
If we just open these public doors ourselves it will not have a big impact on our personal energy level.
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.
No there is no energy star specification for garage doors.
Older garage door openers have a standby power draw as high as 14 watts.

Most door openers have cycle of only a few seconds.
It turns out that doesn t cost you too much thanks to modern tvs.
Kw cost in your local.
The door can be heavy but usually uses counterweights or springs so that the motor isn t lifting a 300 lbs.
The condition of the door seals.
Because garages are typically unconditioned space the potential energy savings from better insulated garage doors is significantly reduced.
If you have an old tv however it can consume as much as 400w in that case your nap costs you about 15c.
Because these electrical appliances operate for only a few minutes per day they don t use much electricity to open and close your garage door.
Not enough to notice.
