200 kilowatt is a lot of power though, and much more than you would see in any household appliance. That might be like running 200 blenders or 3,000 light bulbs, or one Tesla Model 3 with the pedal to the metal.
Energy is measured in watt hours, kilowatt hours, joules, and other units. This is the amount of work that is done by a power source over a period of time. This is what your electric company bills you for. Your hair dryer might use 1.5 kilowatts, but if you use it for 40 minutes in a month, then your electric company will bill you for 1 kilowatt hour.
Now an electric hot water heater might use 200 kilowatt hours of energy in a few months time.
