If you’re looking to trim down your utility bills, a great first step is getting an energy audit. Many utility companies offer free home assessments where a specialist inspects each room and reviews your energy usage. This can help pinpoint where you’re wasting electricity or gas. If a free audit isn’t available, you can do a DIY version using resources from the U.S. Department of Energy. Sometimes, investing in this upfront can pay off later, especially since energy-efficient improvements might qualify for tax credits.
Tweak Your Thermostat Smartly
Adjusting your thermostat can have a surprisingly big impact on your energy costs. According to the Department of Energy, shifting your thermostat by just 7 to 10 degrees for about 8 hours a day could save you up to 10% on heating and cooling. Whether you’re cranking it down in winter or cooling less aggressively in summer, using a smart thermostat can automate this process so you don’t have to remember.
Lower Your Water Heater Temperature
Most water heaters come set at 140°F (60°C), but chances are, you only need it at 120°F (49°C). Turning down your water heater can save you hundreds of dollars annually and also reduce the risk of scalding. It’s a simple fix—just locate your thermostat and dial it down. If you’re unsure, consult a professional to avoid any mishaps.
Unplug What You’re Not Using
Phantom energy—electricity consumed by devices even when turned off but still plugged in—can quietly add up. I learned this the hard way when I noticed my bill creeping higher, only to realize my phone chargers and kitchen gadgets were constantly sipping power. Unplugging devices or using a power strip with an on/off switch can save you roughly $100 a year. Don’t forget to switch off lights when you leave a room or rely on natural daylight when possible.
Run Your Dishwasher Efficiently
Surprisingly, modern dishwashers can be more water and energy-efficient than hand-washing. Since 2013, they’ve been limited to using about 5 gallons per cycle—much less than the 9 to 27 gallons it can take to wash dishes by hand. Loading your dishwasher properly and running full loads helps maximize these savings. This was a revelation for me as a longtime hand-washer!
Take Advantage of Off-Peak Electricity Rates
Some energy providers offer time-of-use plans, charging higher rates during peak hours and lower rates during off-peak times. Running your washing machine, dishwasher, or charging devices early in the morning or late at night can lower your bill. It’s worth checking if your utility has such a plan, especially if your schedule is flexible.
Change Your Air Filters Regularly
Dirty air filters make your heating and cooling systems work harder, driving up energy use. Changing your filters on schedule can reduce your air conditioner’s energy consumption by 5% to 15%, according to the Department of Energy. It’s a quick, inexpensive habit that keeps your home comfortable and your bills in check.
Additional Ways to Save
Beyond these tips, there are many other small changes you can make without spending a dime. The Department of Energy offers a treasure trove of advice, from sealing leaks to installing ceiling fans to cut cooling costs. Even switching to solar panels, if feasible, can make a long-term difference. The key is consistency and awareness—every little adjustment adds up.
