Answer :
In one year, one hour of television use per day would use 36.5 kilowatts.
This is calculated by multiplying the daily wattage (100 watts while in use and 10 watts while idle) by 365 days in a year. Because most televisions are in standby mode when not in use, the 10 watts of power used while idle will be the majority of the total power used over the course of the year.
This means that even though the television is only used for one hour a day, the amount of electricity used while idle adds up over the course of a year. To reduce power consumption, it is important to keep televisions in standby mode when not in use and to unplug them when they are not going to be used for extended periods of time.

Explanation:
First, let's calculate the total number of watts used per day:
100 watts (while in use) + 10 watts (while idle) = 110 watts
To convert watts to kilowatts, we divide by 1000:
110 watts / 1000 = 0.11 kilowatts
So, the TV uses 0.11 kilowatts per hour.
To find the total number of kilowatts used in one year, we need to multiply the kilowatts per hour by the number of hours in a year:
0.11 kilowatts/hour * 1 hour/day * 365 days/year = 40.15 kilowatt-hours per year
Therefore, a TV watched one hour per day would use approximately 40.15 kilowatt-hours per year.
