Generally speaking, for properties such as households, offices, factories and other industrial sites, schools, hospitals, etc., their electrical energy consumption is measured in kilowatt.hours. (kW.h)
For towns, cities, counties, states, countries and other major geographical areas, their electrical energy consumption is measured in megawatt.hours (MW.h) or gigawatt.hours. (GW.h)

Mains power consumption is measured by electricity companies using an Electricity Meter (also known as a Wattmeter), which is normally found in your fusebox.
Power consumption is measured in KiloWatt hours (kWh). 1 kWh is the amount of power used if you consume one kW of power for exactly one hour.
Most of the world provides 240v mains power. In that scenario, 1 kW of power would be required by a load drawing a little over 4A of current at 240v.
(Watts = Volts * Amps)
You do not 'consume' power; you 'consume' energy!
Power is the rate at which you consume energy. Energy is measured in joules, so power is measured in joules per second which, in SI, is given a special name, the watt.
To help you understand the difference, you can think of power as being equivalent to speed (kilometres per hour) and energy equivalent to distancetravelled (kilometres).
Power consumption is measured in many different ways.Power is usually measured in WattsVoltage usually in VoltsResistance in Ohmsand Current (or flow rate) in AmpsGoogle for "Ohms Law"AnswerYou do not 'consume' power. Power is the rate at which work is done.
The unused power goes to "waste"
Since power = voltage2/resistance, reducing the resistance will increase the power of the circuit. Incidentally, power is not 'consumed'; it's energy that's consumed.
Electrical power is measured in watts.AnswerPower is measured in watts. There is no such thing as 'electrical power' as power is simply a rate.voltThe basic unit of electrical power is the watt. If the power is very large, then kilowatts (thousands of watts) or megawatts (millions of watts) are also used.Power is simply a rate, so you cannot really have 'electrical' power, 'mechanical' power, etc. In the SI system of measurements, power is measured in watts (W).Electric power is usually measured in watts, kilowatts, or sometimes megawatts. One watt is equal to one volt-ampere or one joule per second.Electric power is the rate at which an electrical circuit transfers electric energy. The SI unit of power is the watt which is one joule per second.Wattage, Watts, and (W) are what power is measured in there just different ways to say watts."Watts" is the term used to define a quantity of power. If you were looking for a device used to measure power, that is called a wattmeter.Technically, power is a measure of how fast energy is consumed, so energy can be measured as power multiplied by time.AnswerThere is no such thing as 'electrical' power, as power is simply a 'rate'. Power is a measure of the rate of doing work, transferring energy, or of heat transfer. As energy, work, and heat are all measured in joules, power is measured in joules per second which, in SI, is given a special name: the watt.Another example of a 'rate' is velocity. We do not describe different times of velocity; neither should we describe different types of power.Electrical power in SI is measured in watts, or joules per second. It is equal to current times voltage, which is also equal to current squared times resistance. (P=IV and V=IR, where P is power, I is current, V is voltage, and R is resistance.)The watt is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt. The unit, defined as one joule per second, measures the rate of energy conversion.
'Power' is not 'consumed'; it is simply a 'rate' -the rate at which 'energy' is being consumed.No energy is being consumed by a load which is either purely inductive or purely capacitive so, for such loads, the rate of energy consumption, or the power, would be theoretically be zero. However, purely inductive or capacitive circuits only exist in theory, and all circuits exhibit some degree of resistance, so you will never have a condition under which the power of an a.c. circuits truly becomes zero.
