The kilowatt hour is just a unit of measurement for energy, it isn't bad for energy in any way.
Kilowatt-Hours
kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
Absolutely! the rate that energy is used at is called the power. Electrical energy in the home is measured in kilowatt-hours, which is the energy used by a 1-kilowatt device in one hour. If you take a low-power device such as a 20-watt lamp, that takes 50 hours to use one kilowatt-hour because 20 watts is 0.020 kilowatts of power, and 20 x 0.050 is 1.
Gigawatts and kilowatts are units of power, and 1 gigawatt = 1 million kilowatts. Energy is measured in kilowatt-hours or gigawatt-hours, 1 gigawatt-hour = 1 million kilowatt-hours.

No, kilowatt-hours are an exact measure of a quantity of energy. Energy is something that can be measured exactly and if you have an electricity supply at your house there is a meter that measures the kilowatt-hours you use. If you have a 40-watt light, it uses 40 watt-hours if it is on for an hour. If it is left on for 24 hours it uses 40 x 24 watt-hours, which is 0.96 kilowatt-hours, that might cost you 10-20 cents or pence.
Kilowatt-Hours
It is not power which is measured in homes, but energy consumption. Electricity companies charge for energy consumption in kilowatt hours (kW.h). This is done using an energy meter (also known as a 'watt-hour meter' or 'kilowatt-hour meter'), which monitors the supply voltage, and the in-phase component of the load current.
There is no such thing as a "kilowatt per hour". Kilowatt is a unit of power, not of energy. A unit of energy is kilowatt-hour. That's kilowatt times hours, not "per" hour ("per" implies division, not multiplication). If a generator produces 10 kilowatts, that means it produces 10 kilowatt-hours every hour.
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
5 kilowatt of electricity used in 2 hours is 5 x 2 = 10 kilowatt-hoursScroll down to related links below.Additional AnswerA kilowatt hour (kW.h) is a unit of measurement for energy, and is used by electricity companies for the purpose of billing consumers for the energy they purchase. In science and engineering, it is more usual to measure energy in joules (J).A kilowatt hour represents the energy used at the rate of one kilowatt over a period of one hour, where the kilowatt is a unit for power (rate of energy consumption or expenditure).
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
The average yearly electrical consumption around the world for those areas that have electricity is 3,500 kilowatt hours. In the United States the average is almost 11,000 kilowatt hours.
Units of electricity as given on power bills are usually measured in kiloWatt hours. (kW.h) This is a kiloWatt of energy delivered for a period of an hour. It is a unit of power, and a kiloWatt is a measure of energy.
