Cut your utility bills: the moves that actually add up

Most utility advice stops at “turn off the lights.” That’s not wrong, but it’s small. The bigger savings usually come from a handful of moves: how you heat and cool, how you heat water, what rate plan you’re on, and whether you’re paying for help you could get free.

Many households could trim somewhere in the range of $200 to $500 a year by working through the list below. Your number depends on your climate, your home and your local rates. Each move is labeled for renters, owners or both.

What you’re actually paying for

Before you change anything, pull up your last few electric, gas and water bills. Look for three things:

• Usage, measured in kilowatt-hours (kWh) for electricity, therms or hundred cubic feet for gas, and gallons for water.
• Rate, the price per unit. Some plans charge more at certain times of day.
• Fixed charges, the flat monthly fees you pay no matter what. You can’t shrink these by using less, so focus on usage and rate.

In most homes, heating and cooling are the biggest slice of the energy bill, often around 40–50%. Water heating usually comes next. That’s where to aim first.

1. Set the thermostat once, and let it work (renters and owners)

Heating and cooling are the biggest lever, so small changes here matter more than anywhere else.

• Turn it back while you sleep or are away. Setting your thermostat back 7–10 degrees for about eight hours a day can often trim heating and cooling costs by up to 10% a year.
• Use a programmable or smart thermostat so you don’t have to remember. Many utilities offer rebates on these, and some renters can install one with landlord permission.
• Use ceiling fans in summer. A fan cools you, not the room, so it lets you set the thermostat a few degrees higher. Turn it off when you leave.

Typical impact: often $50–$150 a year, more in very hot or cold climates.

2. Lower the water heater temperature (owners, and renters who have access)

Many water heaters ship set to 140°F. Most households do fine at 120°F, which also lowers the risk of scalding.

• Check the dial on your tank and turn it down if it’s set higher.
• If you’ll be away for a few days or more, use the “vacation” setting.
• Wash clothes in cold water. Most of a washer’s energy goes to heating water.

Typical impact: often $30–$100 a year combined.

3. Seal the leaks you can feel (renters and owners)

Drafts around doors and windows let paid-for air escape. Sealing them is one of the cheapest fixes there is.

• Weatherstripping for doors and windows costs a few dollars a roll.
• Door sweeps close the gap under exterior doors.
• Foam gaskets behind outlet and switch covers on exterior walls stop small drafts.
• Owners: caulk gaps around window frames and check attic insulation. Adding insulation costs more upfront but can pay off over several years.

Renters: these supplies are cheap, removable and usually landlord-friendly. Ask first if you’re unsure.

Typical impact: often $50–$200 a year, depending on how drafty the home is.

4. Check your rate plan (renters and owners)

This is the move most people skip, and it can take one phone call.

• Time-of-use plans charge less for electricity at off-peak hours. If you can run the dishwasher, laundry and EV charging at night, you may save. If you’re home all afternoon running the AC, you may pay more.
• Budget billing spreads your annual cost evenly across 12 months. It doesn’t lower your total, but it can make winter or summer spikes easier to handle.
• Choosing your supplier. In some states you can pick who supplies your electricity or gas. Compare carefully: introductory rates can jump after a few months, and some contracts carry cancellation fees.

Call your utility or check its website and ask, “Based on my usage, is there a plan that would cost me less?”

5. Get the free help you’re entitled to (renters and owners)

Utilities and local governments often fund programs that many eligible households never use.

• Free or discounted home energy audits. An auditor checks for leaks and inefficiencies, and some programs include free LED bulbs, low-flow showerheads or weatherstripping.
• Rebates on efficient appliances, thermostats and insulation. Check before you buy, not after.
• Bill assistance. If money is tight, the federal Low Income Home Energy Assistance Program (LIHEAP) and many utility hardship programs can help with heating and cooling bills. Seniors and families with young children are often prioritized.
• Weatherization assistance. Income-qualified households may get insulation and sealing work done at no cost.
• Medical or senior discounts. Some utilities offer reduced rates or shutoff protection for people who rely on medical equipment or are on fixed incomes.

Typical impact: varies widely, from a few dollars in free bulbs to hundreds in assistance.

6. Swap the small stuff (renters and owners)

These aren’t the biggest moves, but they’re easy and they stack up.

• LED bulbs use a fraction of the energy of old incandescent bulbs and last years longer. Start with the lights you use most.
• Smart power strips cut “phantom” power from TVs, game consoles and chargers that draw electricity when off.
• Low-flow showerheads and faucet aerators cut both water and water-heating costs, often for under $20 each.
• Fix running toilets and dripping faucets. A running toilet can waste a surprising amount of water every day.

Typical impact: often $30–$100 a year combined.

7. Plan the bigger upgrades (owners)

If you own your home, some upgrades cost more upfront but pay back over time. Don’t replace working equipment just to save energy; plan the upgrade for when it’s due.

• When your furnace, AC or water heater nears the end of its life, compare efficient models such as heat pumps and heat pump water heaters.
• Check for federal, state and utility incentives first. These change often, so check current rules before you buy.
• Get at least three contractor quotes for big jobs.

Who this is for

• Starting out and renting? Focus on moves 1, 3, 4 and 6. They’re cheap, portable and don’t require a landlord.
• Raising a family? Water heating and laundry (move 2) are likely bigger for you, and assistance programs (move 5) are worth checking if money is tight.
• Retired or on a fixed income? Budget billing can smooth out seasonal spikes, and senior discounts and weatherization programs are often underused.

Start here

Pick two of these and do them today:

• Pull your last 12 months of bills and note your highest-cost months.
• Set your thermostat schedule, or program the one you have.
• Check your water heater setting and turn it to 120°F if it’s higher.
• Call your utility and ask whether a different rate plan, a free energy audit or an assistance program fits your household.
• Buy weatherstripping for your draftiest door this weekend.
