If we assume that you are using a 120V electric pencil sharpener, then it uses approximately 100 Watts.
Over a ten hour period of constant use, that would add up to 1 kWh.

How much electricity does a pencil sharpener use per hour?
As many other devices it depends on the time of use... for example: a regular pencil sharpener as the Panasonic KP380 load is tagged 70W. If a pencil is about 7.5 inches length and each sharpen process takes about 1/2 inches, this means you will have to use it about 15 times in the lifetime of the pencil. Each time lasts about 4 to 5 seconds. For each pencil you need 75 sec (.02083 hrs) . Power usage is (70w)x(0.20833) = 1.45 Wh / pencil. or 0.00145 KWh/pencil
Why is the crant on a meat grinder larger than the crank on pencil sharpener?
It takes more energy to grind meat than it does to take off a few bits of a pencil. The crank on a pencil sharpener doesn't have to be large to spin around efficiently. If you used the same size handle on a meat grinder, you'd be grinding an ounce of hamburger for an hour before getting anywhere. It takes a larger crank to efficiently turn with enough strength to move the grinding mechanism.

This energy is measured in units called kilowatt hours (kW.h) and, for this reason, energy meters are sometimes referred to as 'kilowatt hour meters' or 'watt hour meters'.
