How Solar Panels Can Help You Save on Energy Costs

Making Solar Work for Your Budget

Knowing your household's electricity consumption is more important than ever. With energy costs rising and environmental concerns growing, determining how much electricity your home uses each day can help you make better choices about energy efficiency and sustainability measures, including but not limited to solar panel installation.

Fortunately, there are several reliable resources that can help you make an accurate determination. In this guide, we’ll review how many kWh a house uses on average and why going solar can help you control your energy usage costs.

The National Average: What the Data Shows

According to the U.S. Energy Information Administration (EIA), the average American home uses approximately 28 to 30 kWh per day. More specifically, the EIA reports that in 2022, the average annual electricity consumption for a U.S. residential customer was 10,791 kilowatt-hours, which translates to approximately 899 kWh per month, or about 30 kWh per day.

More recent data from October 2024 shows that average household electricity consumption has increased slightly to 10,332 kWh per year, or 28.4 kWh per day. This represents a growth of approximately 1.25% between March 2024 and January 2025, reflecting seasonal demands and changes in household energy efficiency patterns.

It's important to note that these figures represent averages across the entire United States, and actual consumption can vary significantly based on numerous factors, including geographic location, home size, climate, and lifestyle choices.

Understanding What a Kilowatt-Hour Means

Before going deeper into consumption patterns, it's helpful to understand what we're measuring. A kilowatt-hour (kWh) is the standard unit of energy used by utility companies to measure and bill electricity consumption. One kWh represents the amount of energy required to power a 1,000-watt appliance for one hour.

To put this in perspective:

• A 2,000-watt space heater will consume one kWh of electricity in just half an hour

• A 10-watt LED light bulb would take 100 hours to consume one kWh

• The average home's instantaneous power needs range from approximately 1.2 to 2.3 kilowatts

What Role Does Geography Play in kWh Consumption?

One of the most striking findings from EIA data is how dramatically electricity consumption varies by state and region. Climate plays the dominant role in these differences, particularly the demand for heating and cooling.

According to EIA data, Louisiana has the highest annual residential electricity consumption in the United States at 14,774 kWh per year, which translates to approximately 41.8 kWh per day. This is largely due to the state's hot, humid climate (which creates a need for extensive air conditioning use), combined with relatively low electricity rates that don't discourage high consumption.

On the opposite end of the spectrum, Hawaii has the lowest annual consumption at just 6,178 kWh per year, or about 16.3 kWh per day. Despite Hawaii's warm climate, the state has the highest electricity rates in the nation at approximately $0.44 per kWh, which creates a strong financial incentive for residents to conserve energy.

Regional patterns show that:

• Southern households use close to 37 kWh per day on average

• Northeastern households use approximately 22 kWh per day

• The difference is primarily driven by cooling demands in warmer climates

What Uses All That Electricity? Breaking Down Consumption by End Use

Knowing how electricity is used in your home is important for identifying opportunities to reduce consumption. According to a Residential Energy Consumption Survey (RECS), which is a detailed study of household energy use, here's how electricity is distributed across different end uses.

Heating and Cooling: The Biggest Energy Users

Space heating and air conditioning combined account for approximately 52% of total household energy consumption, making them the largest energy consumers in American homes. However, it's important to note that not all heating uses electricity: many homes use natural gas, fuel oil, or propane for heating.

For electricity specifically, air conditioning accounted for about 19% of total residential electricity consumption in 2020, equivalent to 254 billion kilowatt-hours nationwide. According to RECS data, 88.17% of U.S. homes have air conditioning systems, and nearly 90% of households used air conditioning in 2020. In 2025, those numbers are likely to be the same or even higher.

The prevalence of cooling-related electricity use varies by region. In warm climates like Florida and Texas, air conditioning can represent a much larger portion of household electricity consumption. Central air conditioners, used in 66.48% of U.S. homes, are particularly energy-intensive, with individual units typically consuming between 5 to 14 kWh per day during peak summer months.

Water Heating

Water heating represents the second-largest use of energy in most American homes. In 2020, households consumed an average of 10,566 kWh of electricity, and water heating contributed significantly to this total. The exact percentage varies depending on whether the home uses electric or gas water heating, but it remains a substantial portion of household energy consumption.

Appliances, Electronics, and Lighting

A study noted that appliances, electronics, and lighting consumed 7,526 kWh per household in 2009, and this number has continued to rise despite improvements in individual appliance efficiency. This is because the number of devices consuming energy in homes has increased dramatically.

Some key statistics on specific appliances:

• Refrigeration: Refrigerators are present in nearly every home (99% according to RECS), and they run continuously, making them significant electricity consumers. In 2020, 34% of U.S. homes had two or more refrigerators. Electricity consumption for refrigeration varies by state: households in Washington, DC, consumed an average of 610 kWh annually for refrigeration, while households in Georgia consumed 928 kWh.

• Lighting: In 2020, residential homes used a total of 62 billion kWh of electricity for lighting. However, there's good news here: 47% of U.S. homes were using LED bulbs for most or all of their lighting needs, and nearly half of U.S. households use LED bulbs for all or most of their indoor lighting. Traditional incandescent bulbs use about 60 watts per hour, while LED bulbs use only 8 to 12 watts, representing a prime opportunity for energy savings.

• Laundry: Washing machines consume around 1 to 4 kWh per load, while electric dryers use approximately 5 to 8 kWh per load.

• Entertainment Devices: Primary TVs used about twice as much electricity (210 kWh per home) as second-most-used TVs (106 kWh per home) in 2020, and it’s doubtful that this number has changed since then.

Factors That Influence Your Daily Electricity Consumption

Several key factors determine how much electricity your specific household uses each day. They’re outlined in detail below.

Home Size and Type

Home size is one of the largest factors affecting energy consumption. A 3,000 square-foot home consumes more than double the electricity of a home with less than 1,000 square feet. The average American home is approximately 2,000 to 2,500 square feet and uses 30-33 kWh per day.

According to RECS data, the average single-family detached home in the South consumes the most electricity, while apartments in the Northeast consume the least. In fact, the average household living in a single-family detached home consumed nearly three times more energy in 2020 than a household living in an apartment building with five or more units.

Climate and Weather Patterns

Temperature extremes drive electricity consumption. Homes in states and regions with extreme hot or cold temperatures consume more electricity than those in moderate climates. The EIA uses population-weighted heating and cooling degree days to measure this impact. In 2019, the United States experienced approximately 4,300 weighted heating degree days and nearly 1,500 cooling degree days, explaining why more energy historically has been used for space heating than for air conditioning.

However, this gap is narrowing. The EIA projects that cooling degree days will continue to increase while heating degree days decrease, partly due to climate change and partly due to population migration to warmer regions.

Building Efficiency and Insulation

The quality of a home's insulation, windows, and overall building envelope impacts energy consumption. Newer homes built since 1990 tend to feature better insulation, double-pane windows, and more efficient building envelopes compared to older homes. However, despite these efficiency improvements, newer homes also tend to be larger. According to the RECS, residents living in homes built in the 1980s consumed 77 million Btu of total energy, while those in newer homes built from 2000 to 2009 consumed 92 million Btu per household (19% more), largely due to increased home size.

Household Size and Lifestyle

The number of people living in a home affects electricity consumption, though perhaps not as dramatically as home size itself. Personal and household appliances together account for less than a third of home energy consumption, but large households use them more frequently.

Daily routines and lifestyle choices also play a role. A family that works from home, for example, may use more electricity than one that's out during the day. The adoption of smart home devices has increased energy consumption in some areas: research by consulting firm Parks Associates found that in 2023, the average U.S. home with internet access had 17 connected devices.

Electricity Rates and Economic Factors

Interestingly, the price of electricity influences consumption patterns. Evidence generally shows that households with higher electricity prices tend to consume less energy. Hawaii provides a clear example: with the highest electricity prices in the United States, it also has among the lowest consumption rates. Conversely, Louisiana has some of the lowest electricity prices and the highest consumption.

Appliance Age and Efficiency

The age and efficiency of your appliances make a substantial difference. Older appliances consume significantly more electricity than newer, energy-efficient models. ENERGY STAR-certified appliances use 10-20% less energy than standard models. For example, an outdated air conditioner might use around 1,000 kWh during a hot season, while a newer, energy-efficient model could cut that figure by 20-30%.

How to Calculate Your Home's Daily kWh Usage

To determine your specific household's daily electricity consumption, you don't need to rely solely on national averages. Here's how to calculate it:

• Check Your Electric Bill: Your utility bill should include kWh usage data for the previous 6 to 12 months. Add up the monthly kWh figures and divide by the number of months available.

• Divide by 30: Take your monthly average and divide by 30 to get an approximate daily consumption figure.

• Track Individual Appliances: For a more detailed understanding, note the wattage of your appliances (often listed on the device or in the manual) and estimate how long they're used each day. Multiply the wattage by the number of hours used, then divide by 1,000 to calculate the kWh consumed by each appliance.

• Use Monitoring Devices: Smart plugs or whole-home energy monitors can track electricity usage in real-time, providing detailed insights into consumption patterns.

Monthly and Annual Perspectives

While we've focused primarily on daily consumption, it's useful to understand the broader picture:

• Monthly Average: 855-899 kWh per month according to the most recent EIA data

• Annual Average: 10,332-10,791 kWh per year

• Monthly Cost: The average American household pays approximately $136-$153 per month for electricity, based on average consumption and the national average rate of 15.04-17.01 cents per kWh

These figures have remained relatively stable over the past few years. Despite improvements in energy efficiency, household electricity consumption hasn't decreased much because increased use of electronic devices and larger homes offset efficiency gains.

Trends and Future Projections

According to the EIA's Annual Energy Outlook, several trends are shaping residential electricity consumption:

• Cooling Demand is Rising: Air conditioning energy use is projected to grow faster than any other end use in buildings through 2050, while energy consumption for space heating is expected to decline.

• Population Shifts: The EIA projects that the United States will gain more than 58 million people and 24 million households by 2050, with continued migration to warmer regions in the South and West.

• Total Building Sector Growth: Total consumption of delivered energy by the buildings sector is expected to increase by 7% as growing demand for end uses, including air conditioning, electronics, and water heating, more than offsets declines in energy consumption for heating and lighting.

• Efficiency Improvements: Anticipated gains in energy efficiency from appliance standards and building energy codes will help moderate consumption growth.

How Solar Panels Can Help You Save on Energy Costs

Learning about your household's electricity consumption becomes even more valuable when you're considering solar energy as a way to reduce or eliminate your monthly electricity bills. Solar panels work by converting sunlight into electricity that can power your home, directly offsetting the amount of electricity you need to purchase from the utility company.

Real Savings from Solar Energy

According to industry data, the average U.S. household can expect to save around $1,500 annually on electricity bills after installing solar panels. Over a 25-year period (the typical warranty lifespan of most solar panel systems) the average American homeowner will save approximately $57,000, though savings vary based on location and local electricity rates.

The financial benefits of solar come from two primary sources:

• Reduced Grid Electricity Purchases: When your solar panels generate electricity during daylight hours, that power directly replaces electricity you would otherwise buy from your utility company. The cost per kilowatt-hour for solar-generated electricity is typically much lower than grid electricity rates.

• Protection from Rising Energy Costs: Electricity rates have historically increased over time. By installing solar panels, you essentially lock in your electricity costs for the lifespan of your system (typically 25-30+ years), protecting yourself from future rate increases. Even with modest annual utility rate increases of 3-4%, your solar savings grow year after year as grid electricity becomes more expensive while your solar system costs remain fixed.

For an average residential solar system (typically around 7 to 7.15 kW), producing approximately 965 kWh per month in areas with good sun exposure, homeowners can often cover most or all of their electricity needs. Given that the average American home uses about 900 kWh per month, a properly sized solar system can dramatically reduce or even eliminate monthly electricity bills.

The exact amount you can save depends on several factors:

• Your Current Electricity Consumption: Homes using 30 kWh per day (900 kWh monthly) are ideal candidates for solar.

• Local Electricity Rates: Higher rates mean greater savings: states with expensive electricity costs see faster payback periods.

• Available Sunlight: Geographic location affects how much electricity your panels can generate.

• System Size: Your solar installation should be sized to match your energy needs.

• Available Incentives: Federal tax credits, state rebates, and local incentives can reduce upfront costs.

For homeowners in Delaware, Maryland, New Jersey, and Pennsylvania, solar is an especially compelling opportunity. These Mid-Atlantic states offer strong solar incentives, net metering programs that credit you for excess electricity sent back to the grid, and sufficient sunlight to make solar systems highly productive.

Whether you have a small apartment consuming 600 kWh monthly or a large single-family home using 1,200+ kWh, solar can be scaled to meet your specific needs. The key is working with experienced solar professionals who can assess your home's energy consumption patterns, roof characteristics, and local conditions to design a system that maximizes your savings.

Making Solar Work for Your Budget

Solar panel systems can be purchased outright or financed through solar loans, making the technology accessible regardless of your financial situation. With financing options, many homeowners find that their monthly solar loan payment is less than what they were previously paying for electricity, making them cash-flow positive from day one.

When you consider that the average American home uses 28-30 kWh per day and that solar systems typically last 30+ years while requiring minimal maintenance, the long-term value proposition becomes clear. Every kilowatt-hour your solar system generates is one less kilowatt-hour you need to purchase from the utility company, and those savings compound significantly over the decades your system operates.
