### the basic of energy consumption

Kilowatt per hour is the basic unit of power equal to 1800 kilojoules or the amount of electricity delivered to users by power utilities. The kilowatt is most commonly used as an accounting unit for electricity delivered to residential customers by electric power utilities. This article will introduce you to the basics of energy consumption, including kilowatt per hour.

A kiwi (kiloWatt) is one watt of power or one thousand watts. These units of energy are defined as being any amount of power measured over an hour of continuous use at an average consumption level. It has been stated that a person can heat water three hundred times and cool it one thousand times before the amount of power used in making the process is used up. Therefore, a kettle of boiling water using the same kettle capacity as three hundred kilowatts of power will only last for three hours.

### The time needed to pay for the kilowatt of electricity may therefore be underestimated

One kilowatt hour (kWh) is equal to the amount of power required to operate one light bulb for one hour. Thus a kilowatt of electricity has the same amount of power as one light bulb. Kilowatt per hour is commonly measured in kilowatts (kWh). This unit is often used to compare electricity prices between different suppliers in New Zealand. Unfortunately, there is no common standard for measuring kilowatt per hour.

In comparing prices between suppliers, the amount of time the electricity is supplied may be included. This is not true in the case of solar electricity suppliers. This means that a supplier may supply the electricity at night when it is cheaper to run the machine. However, when daytime arrives the machine should be switched off to ensure that it does not run at night. Therefore, the total amount of time a unit has on a charge will not include the time the unit is switched off.

### Calculating the kilowatt per hour for solar cells is a little bit trickier

This is because the units do not come with a meter and the level of efficiency achieved may not be known. A good rule of thumb is that the cost of electricity per kilowatt hour is roughly four times the cost of the unit.

If you are considering purchasing a solar powered unit, you should also check how efficient the unit is. Units that offer a high number per unit do not offer a great saving. Similarly, a low number of kilowatts produced will mean a large additional amount to the unit price. Once you have found the right unit, you can calculate the correct amount of kilowatt per hour to find out whether a solar powered unit is the right option for you.
