What is a Kilowatt-Hour?

by Simon Thompson
 

You may have come across the term business electricity rates per kWh while looking at energy providers, but what you may not know is what it actually means and how your kWh usage compares to other businesses.

A kilowatt-hour (or kWh) is the name given to the unit of energy that all energy companies use to measure how much electricity or gas you are using. In simple terms, it refers to how much power you are using over a period of time – so a 1kWh drill, for example, will use 1 kilowatt of energy per hour.

Why do you need to know what a kilowatt-hour is?

Some people think that the kWh is the most important piece of information on your bill, as it not only lets you know how much energy your business is using but how much you are paying for it as well.

If you have had a bill that was a lot higher than you expected, for example, you can use your kWh to work out which parts of your business are using more gas and electricity than others. This will lead you to know what parts of your business use the most energy and should drive you to find ways to help these parts of your business to run more efficiently.

It is also helpful to know what a kWh is so that you can fully understand what you are looking at when you are comparing business energy prices per kWh.

What is the difference between kW and kWh?

The easiest way to understand the difference between a kilowatt (kW) and a kilowatt-hour (kWh) is:

  • kW = the power needed to make a device work
  • kWh = the amount of energy used over a period of time

Think of your electrical devices as a car where the kW’s refer to the speed you are driving at and the kWh referring to the distance you are going. The more miles you cover, the more your petrol costs will be, and the more kWh you use the higher your energy bills will be.

As a rough estimate, 1kWh will let you use a desktop computer for 4 hours.

Where can I find kWh on my energy bill?

You can find your kWh on your energy bill under ‘usage’ and it will usually show the abbreviation kWh. This will tell you:

  • How many kWh you used over the billing period
  • How much you pay per kWh
  • Your latest meter readings
