What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
Air Conditioning & Heating
Your HVAC system uses the most energy of any single appliance or system at 46 percent of the average U.S. home's energy consumption.
Your heating, ventilation and air conditioning system likely uses the most electricity at home. The EIA tells us that space heating and cooling accounts for slightly over 30% of residential energy usage. These appliances run frequently, and many factors can affect their efficiency, like drafts and poor insulation.
According to the U.S. Department of Energy, standby power accounts for as much as 5% to 10% of residential energy use, and homeowners could save $100 to $200 each year on utility bills by unplugging devices that aren't in use.
If you want to test how much power your appliances and devices are using in standby mode, you can buy an electricity usage monitor device. These devices allow you to plug in various tech or appliances and check how much power they're actually using, even in standby mode.
Whether you're using your air conditioner in summer or your furnace in winter, this makes up the biggest expense on your electricity bill. In fact, heating and cooling account for close to half of an average household's energy usage. The next highest contributor to your electricity bill is your water heater.
Room air cleaners are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. A standard room air cleaner, operating continuously, uses approximately 450 kWh per year in electricity. This is more than the energy used by some new refrigerators!
Heating and cooling account for 41% of the total electricity used in U.S. homes according to EIA data, making HVAC the largest piece of each home's demand. Space cooling, in particular, accounts for the largest electricity draw in American homes at 16.6%.
Gas ovens are the biggest culprits, so if you have the option, opt for a convection or fan oven. If you get into the nitty-gritty, you'll find microwave ovens are where it's at. They use approximately 50% of the energy produced to cook your kai (food)—win.
Appliances and electronics use energy even when they're turned off. One tip to help save on utility bills is to unplug all electronics — including TVs, computers, and phone chargers — when they aren't in use. Connecting multiple electronics to a power strip makes it easier to switch off unused devices all at once.
So if you still find your electric bill increasing, there may be issues you need to address in your own home. The most common contributing factors are outdated appliances, thermostats, lightbulbs, or insufficient insulation. Here's what you can do to help reduce your household energy usage.
Without further ado, space heating and water heating, on average, are the most energy-consuming equipment. If these appliances are using electricity, they may be what uses the most electricity in your home.
The trick is to buy energy-efficient appliances. Everything from your fridge to your TV and your washing machine can make a huge difference to your electricity bills. When you purchase energy-efficient appliances, you can save up to 90% on your energy costs.
When your devices are plugged in but not in use, they consume electricity, known as the phantom effect. As a result, unplugging those devices can save electricity. Do not worry about unplugging every gadget; simply plug what you can into a power strip so you can unplug less.
Vampire devices are electrical appliances that drain power when left on standby or when they aren't in use. For example, when you turn off your TV there's no picture but the red standby light is still on. This stays on so you can connect with your TV every time you use the remote.

Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
The real issue lies in other appliances that are constantly drawing power, like refrigerators, televisions, and devices plugged into outlets. Hot Water Heater: One of the biggest energy consumers when you're not at home is your electric hot water heater.
Washing machines, dishwashers and tumble dryers account for 14% of a typical energy bill, making them the most energy thirsty. The power they need to heat the water or air inside them means they use more electricity. Checking the energy rating of dishwashers can help you save money.
On average, hair dryers use about 1,500 to 2,000 watts of electricity. Using a hair dryer for 10 minutes per day will use about 9.13 kilowatt-hours of electricity per month and 109.5 kilowatt-hours of electricity per year.
