Kilowatts have numerous applications in different industries and technologies. The most common use of kilowatts is in electrical power generation.

What is the difference between KiloWatts and kilowatt-hours?

Kilowatts and kilowatt-hours measure different things. Kilowatts are units of energy, and they measure available electrical energy. A kilowatt-hour represents 1,000 kilowatts of power used in an hour. Your appliances are rated for the number of kilowatts they will draw when in use.
