Utility bills are one of the largest fixed costs for most US households. Some factors are outside your control — the rate your utility charges, the weather, how well your home is insulated — but there are meaningful actions you can take to reduce consumption and make sure you are not paying more than you need to.
Check how your electricity and gas are priced
How much choice you have depends on where you live. In regulated states, your utility supplies the energy at a rate approved by the state public utility commission. In deregulated states — Texas, Ohio, Pennsylvania, Illinois and a number of others — you can choose a competitive supplier while the utility still delivers the energy and handles outages. If you live in a deregulated state, compare offers on your state's official shopping site rather than a sales call, read the contract length and early termination fee, and check whether the rate is fixed or variable.
Wherever you live, ask your utility about budget billing (also called levelized or average billing). It does not reduce your total cost, but it spreads seasonal spikes evenly across the year, which makes budgeting far easier.
Reduce heating and cooling costs
- Use a programmable or smart thermostat so heating and cooling run only when you need them — the Department of Energy estimates meaningful annual savings from setting the thermostat back while you sleep or are out
- Seal air leaks around doors, windows, attic hatches and outlets — this is usually the cheapest efficiency improvement available
- Add or top up attic insulation if it is thin — attics are where most homes lose the most heat
- Change HVAC filters regularly and have the system serviced so it runs efficiently
- Use ceiling fans to make a room feel cooler so you can raise the AC setpoint
- Check whether your utility offers a free or discounted home energy audit
Reduce electricity costs
- Switch to LED bulbs if you have not already — they use a fraction of the electricity of incandescent bulbs
- Unplug or use smart power strips for devices that draw standby power
- Wash clothes in cold water for most loads and run full loads only
- Air-dry laundry when practical — clothes dryers are among the largest electricity users in a home
- Check whether your utility offers time-of-use rates, and if so shift laundry, dishwashing and EV charging to off-peak hours
- Look for ENERGY STAR rated appliances when replacing an old one
Check for assistance and rebates you may qualify for
Several programs exist for households that need help with energy costs. LIHEAP (the Low Income Home Energy Assistance Program) helps eligible low-income households with heating and cooling bills and some crisis situations — apply through your state agency, which you can find at acf.hhs.gov. The Weatherization Assistance Program funds insulation and efficiency improvements for eligible households. Many utilities run their own low-income rate discounts, medical baseline programs and hardship funds. Federal tax credits are also available for certain home energy improvements — check irs.gov and energy.gov for what currently qualifies.
General guidance only — not regulated financial advice.
Where the savings actually come from
Heating and cooling is the single largest share of energy use in a typical US home, followed by water heating, appliances and lighting. That order tells you where to focus: thermostat settings, air sealing and insulation move the needle far more than switching off a phone charger. Lighting and standby power are worth addressing, but they are small compared with how much energy a furnace, heat pump or air conditioner uses.
Home energy audits
A home energy audit identifies where your home is losing energy and what improvements would pay back fastest. Many utilities offer them free or at low cost to customers, and some states run their own programs. A professional audit typically includes a blower door test to measure air leakage and infrared imaging to find missing insulation. If a paid audit is the only option, weigh the cost against the likely savings — for an older home with obvious drafts, it usually pays for itself.
The single highest-impact action
For most households, the highest-impact action is reducing how hard the heating and cooling system has to work: seal the obvious air leaks, insulate the attic, and use a programmable thermostat. In a deregulated state, comparing your electricity supply rate is a close second and takes about fifteen minutes. Both are one-time efforts that keep paying every month.
