Garage door openers have a "starting watts" and "running watts" ratings. A 1/4 horsepower generally has a starting watts rating of 1,100 and running of 550 watts. A 1/2 horsepower opener uses 1,400 starting watts and 725 running watts.
These are general ratings and to be more precise you would need to know the brand, model and other information on a specific opener.

http://www.booneelectric.coop/coop/tips2.htm According to this webpage the average garage door opener is 800 watts and uses 6¢/hr worth of electricity (based on a 8 cents per kilowatt hour electric rate).
My garage door openers have labels on them saying MAXIMUM 75 watts so I don't think so , but it would depend on the opener ( I use a 60 watt bulb in mine )
Let's start with a typical 110 VAC service. You probably have 20 amp breakers in the service in the garage, and with at least 2 breakers, we have some idea of the theoretical electrical consumption. Remember, Volts X Amps = WATTS, so 110VAC X (2 breakers X 20AMPs) = 110 X 2 X 20 = 2200 WATTS
40 watts
They use about 1200 watts of electricity, which is a LOT!
Use 100 watts
6000 kilo watts
1000 watts
The power consumption of an Xbox can vary depending on the model and usage, but on average, an Xbox console can use around 70-120 watts during gameplay. Idle power consumption is typically lower, around 15-30 watts.
My home averages about 3k watts each hour.
46.6 watts an hour.
