  A) A kilowatt is measure of force. A kilowatt hour is a measure of energy. Therefore a kilowatt hour is a measurement of available power.
  B) A kilowatt is a measure of force per unit area and therefore a measurement of energy. A kilowatt hour is a measure of available power, metered on your electric bill.
  C) A kilowatt is a measurement of the rate at which energy is delivered, which is power. A kilowatt hour is an amount of energy, which is metered on your electric bill.
