A kilowatt-hour (kWh) is a measurement of energy. It's the standard unit your utility company uses to measure how much electricity you use.
While it has a technical definition (one kWh equals 3.6 million Joules), it's much easier to understand in terms of how you use appliances at home.
Your utility company uses the kilowatt-hour (kWh) to bill you for the total amount of electrical energy your home or business consumes over a period.
Every appliance, from your refrigerator to your television, has a power rating in watts.
When you use a 1,000-watt (or 1-kilowatt) appliance for one full hour, you consume exactly one kilowatt-hour of energy. This usage is tracked by your electric meter and shows up on your monthly bill.
A common point of confusion is the distinction between a kilowatt (kW) and a kilowatt-hour (kWh).
Here's a simple analogy to make it clear: Kilowatts (kW) are like your car's speed, and kilowatt-hours (kWh) are like the distance you travel.
Power (kW) measures how fast you're using energy right now (your speed).
Energy (kWh) measures the total amount of electricity you used over your entire journey (the distance you traveled).
To put it in perspective, one kilowatt-hour (kWh) is a significant amount of energy that can power various common household activities.
For example, a single kWh can let you:
This unit provides a tangible way to understand and track your daily energy consumption.
