Wondering how to lower your utlility bills? Utility bills are one of those expenses that drain your budget month after month — and right now, they’re hitting hard. Energy prices have climbed significantly since 2020, driven by inflation, supply chain disruptions, and ongoing geopolitical tensions that affect natural gas and electricity markets worldwide.

Whether you’re trying to cut your electric bill, reduce water usage, or just stop dreading the heating bill every January, these practical tips are proven to make a real difference.

1. Turn Back Your Water Heater

Not only is a too-hot water heater a safety risk, it also costs more money. According to the U.S. Department of Energy, for each 10 degrees you lower your water heater temperature, you save 3–5% in water heating costs. The commonly recommended setting is 120°F — hot enough for most households and safe for preventing bacterial growth.

In summer, 120°F is usually plenty. In winter, you may find you want it slightly higher — but even a modest adjustment from a higher setting saves real money over time.

2. Adjust Your Thermostat by Just a Degree or Two

Small thermostat changes add up to significant savings over a heating or cooling season. Turning the heat down while you sleep or are away from home makes a meaningful difference, and in summer, raising the AC setting even slightly reduces your cooling costs noticeably.

A smart thermostat — like a Nest or Ecobee — takes the guesswork out entirely. You set your schedule once and let it work. Many utility companies now offer rebates on smart thermostat purchases, so check with your provider before you buy. This is one of the best set-it-and-forget-it upgrades you can make.

Installing a programmable thermostat can help you better regulate the temperature at your house.

3. Use Natural Ventilation in Summer

On cooler summer nights, open your windows and let the cool air in. Then in the morning, close your windows and blinds before the heat builds outside. Keeping the sun out during the day is one of the simplest ways to reduce how hard your AC has to work.

The reverse works in winter too — let the sun into south-facing windows during the day to add passive solar warmth, then close blinds at night to retain it.

4. Take Advantage of Energy Efficiency Rebates and Tax Credits

Energy-efficient appliances and HVAC systems cost more upfront but pay for themselves over time — and right now there are meaningful incentives to help offset that initial cost. The federal Inflation Reduction Act extended and expanded tax credits for energy-efficient home upgrades including heat pumps, water heaters, insulation, and more.

Check energystar.gov for current federal credits, and contact your local utility company directly for any state or regional rebate programs they offer. In Iowa, MidAmerican Energy and Alliant Energy both have rebate programs for appliance upgrades — it’s worth a phone call before any major purchase.

Don’t leave money on the table — rebates and tax credits are real and available right now.

5. Turn Off Lights and Unplug What You’re Not Using

Always turn off lights when you leave a room. Beyond that, remember that many appliances and electronics draw a small amount of power even when turned off but still plugged in — this is called “phantom load” or “vampire energy.”

To combat it: unplug items you use infrequently (toasters, phone chargers, hair dryers), or use a power strip and switch it off when you’re done with a group of devices. It’s a small habit that adds up over months and years. This is also one of the easiest ways to reduce your household’s environmental footprint without spending anything.

6. Switch to LED Bulbs

If you haven’t already made this switch, do it now. LED bulbs use up to 90% less energy than traditional incandescent bulbs and last significantly longer than the CFL bulbs many of us switched to years ago. They’ve also dropped dramatically in price — multi-packs are inexpensive and widely available.

Replace bulbs as they burn out and you’ll notice the impact on your bill within a billing cycle or two. LEDs also produce very little heat, which is a bonus in summer — your AC won’t have to work as hard.

7. Wash Clothes in Cold Water

Almost 90% of the energy used to wash a load of laundry goes toward heating the water. Switching even a few loads per week to cold water washes can save the average household over $100 a year in energy costs. Modern cold-water detergents are formulated to clean just as effectively as they do in hot water.

As a bonus, cold water is gentler on bright and dark fabrics, so your clothes hold their color longer.

8. Skip the Heated Dry Cycle on Your Dishwasher

Once your dishwasher finishes washing, open the door and let your dishes air dry instead of running the heated dry cycle. It costs nothing, adds just a few extra minutes of drying time, and reduces energy use. In summer, it also means less steam and heat escaping into your kitchen — which means your AC doesn’t have to compensate.

9. Ask Your Utility Company What Programs You’re Missing

This is the most underused tip on this list. Most utility companies offer programs that customers never ask about:

• Budget billing spreads your annual costs evenly across 12 months so you’re not hit with a huge bill in August or January.
• Free or low-cost home energy audits identify exactly where your home is losing heat or air — and what to fix first.
• Low-income assistance programs are available in most states for qualifying households.
• Rebates on smart thermostats, efficient appliances, and insulation are offered by many providers.

Simply calling your provider and asking “what programs do you offer to help reduce my bill?” is worth 10 minutes of your time. This pairs well with our broader tips on frugal financial planning — knowing what you’re spending and what help is available makes a real difference.

10. Fix Water Leaks Promptly

A leaky faucet or running toilet wastes far more water than most people realize — and you pay for every drop, plus the wastewater treatment fees on top of it.

One summer, our outdoor garden hydrant sprang a leak underground. The city called us before the bill even arrived to flag abnormal water usage. By the time it was fixed, we’d already paid over $80 extra in a single month — nearly a 50% increase. You might not have a leak that dramatic, but even a slow drip from a faucet or a toilet that runs intermittently adds up quickly. Fix small problems before they become big bills.

11. Be Strategic About Cooking

Your oven is one of the most energy-intensive appliances in your kitchen — and how you use it matters.

• Batch bake whenever possible. If the oven is already hot, put something else in at the same time or immediately after. Our freezer-friendly recipes are perfect for this — make a double batch while the oven is on.
• Avoid the oven on hot summer days. Use a slow cooker, Instant Pot, air fryer, or outdoor grill instead — all of them produce far less waste heat, which means your AC doesn’t have to compensate. Try our Instant Pot whole chicken as a great summer alternative to roasting in the oven.
• Use lids on pots. Covered pots bring water to a boil faster and use less energy doing it.
• Match pot size to burner size. A small pan on a large burner wastes a significant amount of heat.

These small cooking habits won’t show up as a single dramatic line item on your bill, but they contribute meaningfully over the course of a year — especially in summer when you’re also paying to cool your home.

The Bottom Line

You don’t have to make all of these changes at once. Pick two or three to start, build the habits, and add more over time. The families who consistently keep utility bills low aren’t doing anything dramatic — they’re doing small things consistently. In today’s economic climate, that consistency matters more than ever.
