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.
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.
Use a device that plugs into the same electrical outlet as one of your appliances. It will measure how much electricity that appliance is using. Or consider installing one of several devices available on the market that work with your meter to monitor usage in real time and even capture usage statistics.
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.
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.
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.
The most common reasons for a big jump in your electric bill include changes in your lifestyle, increased usage of energy-hungry appliances, and sudden weather changes.
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!
The biggest source of energy use in your home is your heating and cooling system. 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.
Fridges & freezers
Cold appliances are consuming energy 24/7 because they need to regulate the same temperature to keep your food fresh. It's important to know that the average fridge-freezer has a lifespan of 17 years, so the one you choose will make an impact on your energy bills for long stretch of time.
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.
A watt meter can help you see if a certain device is using power even when it is turned off. This device plugs into the wall, and then you plug your appliance into it to see how much power is being used.
Did you know that when your appliances or electronic devices are plugged in, they're draining energy – even if they're not in use? Phantom power, also called standby power, refers to the energy that's wasted around your home when devices are plugged in and using power, but you're not actively using them.
You're Using Older or Less Energy-Efficient Appliances
Large appliances like your washer and HVAC system consume the most home power. If the majority of your appliances are 10 or more years old, they may be using significantly more energy than newer, high-efficiency models.
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.
To get specifics regarding your energy usage, you need an electricity usage monitor that tells you exactly how many kWh a device or appliance is drawing. It can be as simple as a "plug load" monitor that plugs into an outlet. You then plug the device/appliance into the monitor.
Your electric bill is likely to account for the highest expense on your monthly utility bill. Most Americans find their electricity usage is 41% heating and cooling, so that's often the biggest expense.
