Getting your electricity bill at the end of the month often leaves us wondering when we used up so much energy. But if you are tired of wondering how your bill got that high, you may want to know how to calculate your daily energy use for each appliance.

It's also important to know how your home consumption compares to the national average to determine if you are spending too much or not. So let's find out how many kWh your home uses and factors that contribute to your home power usage.

Simply put, kW or Kilowatt is a unit for measuring electrical energy while kWh or Kilowatt-hours measures your energy usage over time. To explain more elaborately, Kilowatt is equal to a thousand watts (1000W). It is the amount of energy an electrical appliance consumes.

On the other hand, a Kilowatt-hour is the amount of energy an appliance uses every hour. So, one Kilowatt used for an hour equals 1kWh. KWh is the unit used for your electricity bill. It not only tells us the number of Kilowatts an appliance consumes, but Kilowatt-hour tells us the amount of energy consumed and how long it takes to use a Kilowatt.

While many factors influence your specific house energy consumption (more on this later), the average household consumption will help you know the rough estimate for households. Knowing the average helps you figure out if you are above or below the average.

This report is based on EIA's () updated electricity use. EIA reports that the average annual electricity consumption per household in 2021 is 10,632 kWh, making an average of 886 kWh per month.

The table below shows the average kWh for a single American household daily, monthly, yearly, and instantaneously. Instantaneous use refers to the power needed in an instant. Dividing 10,632 kWh by 365 days, we get a daily average of 29 kWh.

To determine the instantaneous usage, we find the number of hours in a year - 365 times 24 = 8760. Then we divide 10,632 by 8760 hours, which is 1.2 kW

Using the single resident average, we calculate the aggregate average power consumption for American residents. The EIA estimates as 123,530,000 and the aggregate yearly consumption was 1,497,767,000,000 kWh. Below, we use this estimate to find the daily, monthly, and instantaneous aggregate.

Typically, there is a lot of variance between states with some ranking high and others low. According to the EIA report in 2021, Louisiana had the highest annual consumption at 14,302 kWh per household and 1200 kWh per month. Hawaii ranked lowest at 6,369 kWh and 537 kWh per month.

Considering the average consumption per household in your state will help you better understand your energy consumption and work towards reducing your carbon footprint if you are above the average.

This variation also applies to the cost per kWh with Oklahoma, Idaho, Arkansas, Louisiana, Utah, Washington, and North Dakota charging as low as $0.10. Hawaii's electricity bill proves to be the highest at $0.30, with Alaska falling $0.7 behind at $0.23.

We created a table showing the different states and their power use daily, monthly, and yearly, and the electricity cost per kWh for each state. The table below is drawn from the EIA table for each state in the US.

Although Americans make up less than 5% of the world's population, they make up 25 % of the world's energy consumption. Each American uses an average of 4,500 kWh per year in their home. The US average is surprisingly about six times the global average per capita or over five times the average for those with access to electricity.

Besides America, the difference between developed countries is wide. The US and Canada's consumption is around 4,500 kWh per individual. But in Brazil, Mexico, and China, it's around 500 kWh per individual.

However, this difference doesn't account for the growth in energy consumption. For example, while Brazil's use is as low as China's, it has been stable for the last 20 years. On the other hand, China's has increased by 600%.

Of course, everyone’s electricity bill won't be the same, and understanding why is not as simple as it seems. Numerous factors can affect your home’s energy usage, making you use below or above the household average.

1. Size of your home

Typically, a bigger house will consume more energy than a smaller house. This is because you will require more energy to heat or cool a larger space.

2.The age of the house and type of building material

Older homes use up more energy because building materials weaken over time, causing heat loss. Also, the type of material used will affect how much energy you use.

Less energy-efficient materials, like the ones used in older homes, allow air to escape. But energy-efficient materials will reduce air leaks.

3.Number of occupants

More occupants will mean higher energy consumption. From charging phones to using the washing machine, energy consumption is bound to be higher than that of a smaller household using the same appliances.

4.Type of appliances

Different appliances consume different amounts of energy. Energy-consuming appliances will increase your average consumption but energy-efficient appliances will use less energy.

5.The number of appliances

If you have more appliances than your neighbor, you may consume a bit more energy, especially if they are energy-intensive.

6.How often appliances are used

Every time you use an electrical appliance, it consumes energy. So, how often you use your appliances will affect your average energy use.

7.Geographic location

The area you live in can affect how much energy you use. If you live in a region with extreme temperatures, you will end up consuming more energy for cooling and heating than in milder areas.

8.Season and weather

Seasons and weather conditions may influence your average energy use. Sunny days and the summer months will require more cooling. Rainy days and the winter months will require more heating.

Several factors will determine what appliances contribute most to your home's power consumption. So there's really no straight answer to this. Some factors you should consider are which appliances you use often and the type of appliance. However, some appliances typically contribute most to power consumption:

1.Heating and cooling equipment

Heating and cooling appliances like air conditioners and heaters consume a lot of energy. This is especially because they are used very frequently in the home.

2.Water heater

Water heaters are the second most energy-consuming appliance in the home. They consume a lot of energy because they have to heat a lot of water for laundry, dishwashers, showers, etc.

Water heaters account for approximately 18% of your electricity bill, and says the average household spends between $400 and $600 on water heating every year.

3.Lighting

The Department of Energy says that lighting accounts for about 15% of an average home's electricity use. Lighting is a necessity which is why a lot of energy is used for lighting.

But, replacing incandescent bulbs with energy-efficient bulbs like LEDs can significantly reduce your bill. It can save about $225 in energy costs per year for the average household.

4.Refrigerators

Refrigerators are one of the largest appliances in the home and they equally consume a lot of energy. Most homes have two or more and keep at least one of them on throughout the day. Hence, increasing power use.

In 2015, estimated that refrigerators account for 7% of the average household's energy consumption. However, in 2022, it .

5.Washing machines and cloth dryers

While doing the laundry may be a once-in-a-week routine, your washing machine and dryer still fall among the most energy-consuming appliances. It makes up about 5% of your monthly energy use. The percentage becomes higher in homes with many occupants.

6.Home entertainment systems

Your home entertainment system including televisions, TV boxes, gaming consoles, and home theater contribute significantly to your energy use. In 2022, these devices consumed a total of 54 billion kWh which makes up 4% of the total American home use.

7.Kitchen appliances

Electric oven, electric kettle, dishwasher, and other electrical kitchen appliances do contribute to your energy use. While separately, they make up around 1% of your energy bill, collectively, they make up a significant percentage.

Calculating how many kWh an appliance uses is quite simple and requires no special mathematical knowledge. You need to multiply the wattage of the appliance by the amount of time (hrs) it was used and then divide it by 1000.

The formula for calculating kWh is: kWh = Wattage × hours used ÷ 1000

For example, a 100 Watt lightbulb was used for 500 hrs in a month. The kWh will be: Monthly kWh = 100 × 500 ÷ 1000 = 50. Monthly kWh for 100 Watt lightbulb = 50 kWh.

Reducing your home power consumption simultaneously reduces your electricity bill. The best way to reduce your home power consumption is to:
