Killowatt Hours Are Adding Up





A kilowatt-hour is the electrical energy consumed in one hour at the constant rate of one kilowatt. The average household in the United States uses about 8,900 kilowatt-hours of electricity each year. Power is defined as the rate at which work is done or energy is consumed. The formula for average power is acquired by dividing work by the time needed to perform work: P = W/t. Power has units of newton-meters per second or joules per second or watts.



The electric power produced for our residences come from power plants through a power distribution grid. The electric power derives from a power site within the power plant. The power site of a power system consists of a central mover like a turbine that is then pushed by water or steam to run a system of generators.

The amount of power that a household consumes depends on how many appliances there are and the amount of time they are in use. Some appliances or machineries take a lot of energy to operate, so it will result in more use of power.

But wait!

That guy couldn't be from the electric company because he's got phones hanging from his belt. And of course there would be absolutely no need to measure the voltage of the current, because that's fixed. No, he's trying to track down telephone lines.

Oh, well. Never mind.
