What is a Kilowatt-Hour?

A kilowatt-hour (kWh) is a measure of electrical energy that gages the amount of electricity in thousands, being generated or consumed in one hour.

What is Measured in kWh?

Devices that use a significant amount of energy or are used frequently are often measured in kWh. Common household appliances, heat and cooling systems, electronics, solar panels, and electric vehicles are a few examples of devices whose energy usage is measured in kWh.

How to Calculate the Kilowatt-Hour of a Device:

The power rating of household appliances are typically measured in watts. For example, you may own a 600 watt microwave. That microwave’s energy rating over one hour is calculated by dividing the wattage by 1,000 to find its equivalent in kilowatts. In this case, the microwave will use .6 kWh of energy in one hour.

kWh and Energy Efficiency

Being aware of your devices’ energy demands is a critical way to ensure low electric bills and maximize your home’s energy efficiency. The energy usage of some devices may be surprisingly high and simply keeping them plugged in can drive up your home’s consumption level.

Investing in energy efficient devices and power strips can help to regulate your devices’ usage and only consume power when necessary. Although the initial purchase may be more expensive, you’ll see lower bills overtime and save money in the long-run.

kWh and Your Electric Bill

The amount of electricity you use over a monthly period is measured on your electric bill. The amount of money you are charged is reflective of your electric demand, in addition to your supplier’s fees. The higher your consumption (in kilowatt-hours) the more you will get charged.
