Average US electricity usage: ~900 kWh/month
The average US household electricity consumption is around 900 kWh per month, or about 30 kWh per day. This equates to an average of 10,791 kilowatt-hours of electricity per year. However, it is important to note that electricity usage varies significantly across the country.
Several factors influence the variation in electricity usage across the United States. One key factor is the geographic location and climate. States with hot, humid summers, such as Louisiana, tend to have higher electricity consumption due to the increased use of air conditioning. Similarly, states with colder winters will see a rise in electricity usage for heating. The type of building and its construction play a role too. For example, detached homes in the South are more likely to have electric heating and air conditioning, resulting in higher electricity consumption.
The size of the home is another critical factor in electricity usage. Larger homes typically consume more energy as it requires more power to heat and cool a bigger space. The number of residents also contributes to electricity usage, as more people generally result in higher electricity usage. Additionally, the number and type of appliances used in a home can significantly impact electricity consumption. For instance, the use of multiple refrigerators, dryers, and dishwashers can drive up electricity bills.
To reduce high electricity usage, individuals can consider implementing energy-efficient systems, such as efficient air conditioning, space heating, and water heating systems. Additionally, simple habits such as turning off lights and TVs when not in use can help lower electricity consumption. By understanding these factors and making conscious choices, households can work towards managing their energy usage and reducing their environmental footprint.

Louisiana's electricity usage: highest in the US
The average annual amount of electricity sold to a U.S. residential electric-utility customer was 10,791 kilowatt-hours (kWh) in 2022, with an average of about 899 kWh per month. However, Louisiana had the highest annual electricity purchases per residential customer at 14,774 kWh in 2022, with the second-highest being 14,407 kWh in 2020. Louisiana's hot and humid summers, coupled with its mild winters, contribute to its high electricity usage. The state's climate necessitates the use of energy-intensive air conditioning and heating systems, which are major factors in its high electricity consumption.
Louisiana's electricity is primarily generated using natural gas, which accounted for 76% of the state's electricity net generation in 2023. The state has the third-highest marketed natural gas production and the seventh-highest natural gas reserves in the U.S. While solar power usage for electricity production in Louisiana has increased significantly, the state still has a long way to go in terms of renewable energy sources. Louisiana has little onshore wind energy resource potential and no utility-scale wind power generating facilities.
The industrial sector consumes the most electricity in Louisiana, accounting for about 42% of the state total, followed by the residential sector at 33%. The high electricity consumption in the residential sector can be attributed to the heavy reliance on electricity for home heating and air conditioning. Additionally, the size of homes in Louisiana, as well as the number of residents and appliances, can also contribute to higher electricity usage.
Louisiana's high electricity usage has implications for its carbon footprint. The state's electricity use levels result in CO2 pollution, with emissions per person ranking as the 8th worst in the U.S. The state also imports a significant portion of its electricity, receiving about one-seventh of its power from other states. This reliance on external sources further contributes to Louisiana's overall impact on the environment.

Hawaii's electricity usage: lowest in the US
Hawaii has the fourth-lowest electricity usage in the US. In 2022, the average annual electricity consumption for a US home was 10,632-10,791 kilowatt-hours (kWh). Louisiana had the highest annual electricity purchases per residential customer at 14,774 kWh, while Hawaii had the lowest at 6,178-6,369 kWh per residential customer.
Hawaii's low electricity usage is partly due to its successful implementation of renewable energy sources. In 2024, about 33% of Hawaii's total generation statewide came from renewable sources of energy, with solar power providing about 22% of that. Hawaii has the 11th-highest small-scale solar generation among US states. The state also has initiatives in place to promote the use of electric vehicles, such as designated parking spots and rebates for installing charging stations.
However, Hawaii's energy consumption is dominated by oil or petroleum, which provided 83% of its energy in 2016, reducing to 65% in 2024. This is due to Hawaii's isolated location and lack of fossil fuel resources, which make it reliant on petroleum imports. The transportation sector uses about two-thirds of all petroleum consumed in Hawaii, with jet fuel accounting for nearly half of this.
To reduce its reliance on petroleum, Hawaii has set goals to increase its use of renewable energy. The three big islands of Kauai, Hawaii, and Maui are required to obtain 100% of their electricity from renewables by 2035. Hawaii has also banned new coal plants and is researching and implementing wind power and biomass energy sources.

Size of home: bigger homes use more energy
The size of your home is the largest factor when it comes to how much energy you use. Larger homes typically consume more energy than smaller homes because it takes more energy to heat and cool a bigger space. The Department of Energy estimates that the average American home uses "101,800 British thermal units (Btu) of energy per square foot" each year. Most homes are around 2,500 square feet, so a bigger home with more than 4,000 square feet could expect to use over 400 million Btus of energy per year.
In Texas, for example, air conditioners and electric heating systems account for a large percentage of energy usage in the winter and summer, so the square footage of your home can have a big impact on your electricity bill. In 2020, the average household living in a single-family detached home consumed nearly three times more energy than a household living in an apartment building with five or more apartments.
The number of residents in a home also impacts energy usage. More people living in a home using devices and appliances will increase average household electricity consumption. Similarly, the number of appliances used in a house will also increase energy usage. Newer homes tend to have more appliances, such as dishwashers, clothes washers, clothes dryers, and two or more refrigerators, which can contribute to higher energy usage.
Additionally, the location and climate of a home can affect energy usage. Homes in areas with milder weather may be able to cool or heat their homes more efficiently than homes in areas with more extreme temperatures. For example, Louisiana, with its hot and humid summers, has the highest annual electricity use at 14,774 kWh per residential customer in 2022.
The building materials and year of construction of a home can also impact energy efficiency. Older homes may not be well insulated, leading to higher energy usage. Newer homes may have improved energy efficiency due to better insulation and more energy-efficient appliances.

Number of residents: more people use more energy
The number of people living in a household is a significant factor in determining the average household electricity usage. A larger household will use more electricity as there will be a higher frequency of appliance usage. For example, a household of four adults in a 2000 sq ft house averaged 95 kWh per person per month. In comparison, a household of two people in Spain averaged 79 kWh per person per month.
The size of the home also plays a role in electricity usage, with larger homes typically consuming more energy for heating, cooling, and lighting. A 3000 sq ft home consumes more than double the electricity of a home with less than 1000 sq ft. The average American home is approximately 2000 sq ft and uses 30-33 kWh per day.
The number of residents and the size of the home are closely linked, as a larger household will likely require a bigger home. Additionally, the geographic location and climate can impact electricity usage, with homes in hotter or colder climates using more energy for heating and cooling. For example, Louisiana has high electricity usage due to its hot and humid summers, while Hawaii's mild climate results in lower electricity consumption.
The type of building materials and insulation can also affect electricity usage. Wood and brick, for instance, are poor thermal conductors that prevent heat transfer, helping to keep the indoor temperature stable. Proper insulation is crucial, as it degrades over time, leading to energy loss and higher electricity bills.
Overall, the number of residents in a household directly influences electricity usage through the increased frequency of appliance usage and the likely larger size of the home. Combining this with geographic factors and building materials, the average electricity usage per person in a household can vary significantly.
