In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
Heating and cooling (HVAC) systems are the biggest energy consumers in a typical house, accounting for roughly 45−50% of your total electricity usage. Water heaters, refrigerators, and lighting round out the rest of the major draws.
The fix: Lower your home temperature to 68 degrees when you're home. Maintain comfort by adding extra layers of clothing – try fabrics like fleece, flannel and wool – and don't forget comfy slippers and blankets. If you can comfortably go a degree or two cooler than 68, your wallet will benefit even more!
The Top Energy-Draining Appliance: Space Heating & Cooling
This includes both forced-air systems, heat pumps, furnaces, baseboards, window A/C units, and fans. Because they run for long periods and often at high wattage, they dominate the consumption profile.
What Causes High Electric Bills?
Yes, unplugging a washer and dryer does save electricity, but the savings are practically negligible. These appliances only draw "phantom power" (standby energy) for digital displays or electronic clocks when not running, typically costing pennies a year.
Greater use of home and devices
Working from home increases energy usage. You may run your air conditioner more or keep your heat higher to be comfortable. Your computer, printer and other electronics will draw energy all day. You may need brighter lighting, too.
In most households, Heating and Cooling (HVAC) systems consume the most electricity, accounting for roughly 40% to 50% of your total energy bill.
Appliances all over the home can draw phantom power. In some cases, such as with smart light bulbs, it's pretty minimal. Entertainment-related devices, like set-top boxes for recording TV shows and gaming consoles, can drain a lot of energy when they're just in standby mode.
Because they do not use standard grid electricity or conventional electric and gas furnaces, the Amish heat their homes using off-grid, self-reliant methods. The most common systems include wood- or coal-burning stoves, propane and kerosene heaters, and natural airflow home designs.
While it may seem like you're saving energy by keeping the heater off, you're actually forcing your heating system to work harder when you decide to turn it back on. So, does turning the heater on and off raise the bill? Yes!
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
Always unplug small heat-generating appliances (like space heaters, hair tools, and toasters) when not in use to prevent fire hazards. Additionally, unplug electronics and idle "energy vampires" (microwaves, coffee makers, and chargers) to eliminate phantom power drain.
Running a 500-watt device costs approximately $0.09 per hour based on the 2026 U.S. national average residential electricity rate of 17.91 cents per kWh.
In most homes, heating and cooling (HVAC) consume the vast majority of energy (nearly 50%), followed by water heating and large appliances. You can drastically lower your utility bills by optimizing these top five household energy drains:
Gregor recommends unplugging microwaves, coffee makers, toasters, blenders, food processors, kettles, slow cookers, rice cookers, and ice makers — pretty much any small kitchen appliance. Appliances with an auto timer are especially important to unplug, according to Tom Jameson, owner of AstroWatt Electric.
Electricians keep one hand in their pocket—a practice known as the "One-Hand Rule"—to prevent electric current from traveling across their chest and through their heart.
You do not need to unplug your smart TV daily, as modern sets are designed to remain on standby. However, doing so can prevent "phantom" power drain, shield the TV from electrical surges, and occasionally resolve minor software glitches by forcing a system reboot.
The top 5 worst appliances to leave on standby
The answer to when to do laundry to save money
Most people will see that they have a lower tariff overnight, usually between 11 pm and 7 am. This is the best time to do your washing as you'll save money. Saving money on electricity is only part of the equation.
The cheapest way to cook combines using energy-efficient appliances with budget-friendly ingredients. Microwaves are the most economical appliance since they heat food directly in a fraction of the time. Pair this with low-cost staples like dried beans, rice, lentils, and seasonal produce for the most affordable meals.
A toaster draws a lot of power while running (between 800 and 1,500 watts), but because it only operates for 2 to 4 minutes per use, its overall electricity consumption is quite low.
What is Always On? Always On is a measure of the base or basic usage of electricity in your home. Always On is comprised of appliances and electronic devices that are always plugged in and are consuming energy even when not being used.
Many folks go by the 50-50 rule. If the appliance has reached 50 percent of its expected life and it costs more than 50 percent of the cost of new, buy a new one. Oven failures can start with underperformance. For example, a family favorite just doesn't come out like it used to.
