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
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.

Hoovers use 1000 - 2000 watts
Abut 20 watts.
The average freezer uses around 100-400 watts of electricity, depending on its size and efficiency. This translates to about 2.4-9.6 kWh per day, or around 876-3504 kWh per year.
25 watts.
it may use 15 to 25 watts
3/4 of watts
I read somewhere that it's 100 watts.
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 )
Not very many, probably less than 20 watts.
A small one 100 watts, a large one 1000 watts or more.
