How many watts per year?

Answer 1

Watts is the product of amps times volts. As you can see this combination could have lots of variables depending on the different voltages that are in use and the variable amperage's of multiply loads. To find watts per year you would first have to find the wattage of the device, then extend it to watts per hour if the device is continually on. Then take this figure times 24 hours in a day and then finally times 365 for the days in a year. This will give you the answer that you are looking for.

Alternate answer: The question is fundamentally meaningless. A watt is a measure of energy per unit time. An appliance that uses 60 watts, will use 60 watts in a second, 60 watts in a minute, 60 watts in an hour, or 60 watts in a century. Total energy can be expressed in units like "kilowatt-hours" (equal to 1,000 watts for one hour, or 100 watts for 10 hours, etc.). Our 60-watt appliance, left on continuously, will use about 525 kWh per year.
