The average American household pays $1,650/year on electricity. The tips below are sorted by impact — highest savings first — so you can prioritize where to focus.

Free Changes (Do Today)

1. Raise Your Thermostat 2–3°F in Summer

Every 1°F increase in your cooling setpoint saves approximately 3% on cooling costs. Raising from 72°F to 76°F = 12% cooling savings. On a $150/month summer electric bill where AC is 50%, that's $9/month or $108/summer — for free.

Better: Use a schedule. 78°F when you're home, 82°F when you're away, 80°F at night.

2. Run Appliances at Night (TOU Rate Hack)

If your utility has time-of-use (TOU) rates (common in California, Texas, New York, and increasingly nationwide), your electricity is 30–60% cheaper at night. Check your bill or utility app for rate schedule.

Run your dishwasher, washing machine, and EV charging after 9 PM. This simple scheduling can save $150–$400/year with no new equipment.

3. Unplug Standby Electronics

Cable boxes, gaming consoles, and older TVs draw significant power 24/7. Plug them into a smart power strip that cuts power when the main device turns off.

Top phantom load offenders:

• Cable/satellite box: 15–20W standby = $21–$28/year
• Game console (Xbox, PlayStation): 10–40W = $14–$56/year
• Desktop computer + monitor: 5–20W = $7–$28/year
• Coffee maker with clock: 2–5W = $3–$7/year

Total phantom load savings: $75–$150/year

4. Wash Clothes in Cold Water

Modern detergents work as well in cold water as hot. Heating water accounts for 90% of the energy a washing machine uses. Switching from hot to cold wash saves approximately $60–$100/year for an average household.

5. Air-Dry Dishes

Skip the heated dry cycle on your dishwasher — open the door after the wash cycle and let dishes air dry. This eliminates 15–30% of dishwasher energy use, saving about $20–$40/year.

Low-Cost Upgrades (Under $50)

6. Replace Incandescent Bulbs with LEDs

A 9W LED replacing a 60W incandescent saves 51W. At 4 hours/day use and $0.16/kWh: $11.90/year per bulb. A 30-bulb home switch saves $150–$360/year with $30–$100 in bulb costs. Payback: under 3 months.

7. Install a Smart Power Strip

Smart power strips detect when the main device (TV, monitor) turns off and cut power to all connected devices simultaneously. Cost: $25–$40. Annual savings: $50–$100. Payback: under 6 months.

8. Add Weatherstripping to Doors and Windows

Gaps around doors and windows allow conditioned air to escape, forcing your HVAC to work harder. Foam or V-strip weatherstripping costs $5–$15 per door. A typical home with 3 exterior doors and 10 windows can seal all of them for $50–$100 in materials.

Annual savings: $75–$200 depending on how leaky your home was. See our DIY weatherstripping guide for step-by-step instructions.

9. Install a Shower Timer or Low-Flow Showerhead

If you have an electric water heater (which uses ~$400–$600/year of electricity), cutting shower time or flow rate cuts that bill proportionally. A 1.5 GPM showerhead ($15–$30) replacing a 2.5 GPM head saves 40% of shower water heating cost — roughly $60–$100/year on electric water heating.

10. Clean Your Refrigerator Coils

Dirty condenser coils make your refrigerator work 5–15% harder. Pull the fridge out and vacuum the coils every 12 months. Takes 10 minutes, costs nothing, saves $30–$80/year on refrigerator electricity.

Medium-Cost Upgrades ($50–$500)

11. Install a Smart Thermostat

A properly programmed smart thermostat saves $100–$300/year by automatically adjusting temperature when you're away or asleep. Cost: $100–$250 installed. Payback: 6–18 months. Many utilities offer $50–$150 rebates.

Top picks: Ecobee SmartThermostat (best data + Alexa built-in), Google Nest Learning Thermostat (easiest setup), Honeywell T9 (best multi-room sensing).

Qualifies for the $150 IRA Section 25C credit? No — thermostats don't qualify. But the home energy audit that identifies where to use it does.

12. Seal Air Leaks with Caulk and Foam

The average American home leaks enough air to fill a basketball court 27 feet high. Sealing caulk around window frames, electrical outlets, and pipe penetrations costs $20–$75 in materials and can save $150–$400/year in HVAC costs.

Highest-priority spots: attic hatch, recessed light fixtures (pull down from attic side), top plates in the attic, and basement rim joists. See our DIY home energy audit checklist for exactly where to look.

13. Add Attic Insulation

If your attic has less than 12 inches of insulation, adding more is often the single highest-ROI home energy project. DIY blown cellulose costs $0.20–$0.30/sq ft in materials. A 1,500 sq ft attic: $300–$450 in materials, plus a $750–$1,500 rebate from your utility and a 30% IRA tax credit on materials.

Annual savings: $150–$350. Payback: 1–3 years.

14. Install an Energy Monitor

A whole-home energy monitor (Emporia Vue, Sense) clamps onto your electrical panel and shows real-time electricity use by circuit. It identifies which appliances are using the most electricity so you know exactly where to focus. Cost: $150–$300. Often reveals $200–$600/year in savings from behavioral changes alone.

15. Replace an Old Refrigerator

A refrigerator more than 15 years old typically uses 700–1,200 kWh/year — 2–3× more than a modern ENERGY STAR model (250–400 kWh/year). Annual savings from replacement: $70–$150. Many utilities offer $50–$100 appliance recycling rebates.

High-Impact Upgrades ($500–$5,000)

16. Install a Heat Pump Water Heater

Electric resistance water heaters (the tank type in most homes) are 100% efficient — they use 1 kWh of electricity to produce 1 kWh of heat. A heat pump water heater is 300–400% efficient — it moves heat from the air instead of generating it.

Annual savings: $400–$600/year vs. an electric resistance tank. Cost: $800–$1,800 installed. After the $2,000 IRA Section 25C credit, payback is often under 1 year.

17. Seal and Insulate Ductwork

Leaky ducts waste 20–30% of the air your HVAC conditions. Sealing accessible duct joints with mastic sealant (not duct tape — it fails over time) and insulating ducts in unconditioned spaces (attic, crawl space) costs $300–$800 DIY or $1,000–$2,500 professionally.

Annual savings: $200–$500. Payback: 2–4 years.

18. Add Insulation to Basement Rim Joists

The rim joist (where the floor framing meets the foundation) is often completely uninsulated in homes built before 1990. Cutting rigid foam insulation to fit each joist bay and sealing with spray foam costs $150–$400 in materials and half a day of work.

Annual savings: $100–$250. Payback: 1–2 years.

19. Replace Single-Pane Windows

Single-pane windows lose 5–10× more heat than double-pane low-E glass. Replacement windows cost $400–$800 per window installed. Annual savings per window: $50–$150 depending on size and climate.

The IRA Section 25C credit covers 30% of the cost up to $600 total for windows. Payback: 5–15 years — one of the longer paybacks on this list, but window replacement also improves comfort, noise reduction, and resale value.

20. Install a Ductless Mini-Split

If you're using window AC units or electric baseboard heat for one or two rooms, a ductless mini-split (heat pump) operates at 200–350% efficiency compared to those systems' 100%.

Annual savings vs. window AC: $100–$300 per zone. Cost: $1,500–$4,000 installed per zone. After the $2,000 IRA credit: $0–$2,000 net for a single zone. See our heat pump installation cost guide for full pricing.

Major Upgrades (Over $5,000)

21. Replace Your HVAC System with a Heat Pump

If your central AC or furnace is 10–15 years old and needs replacement, replacing with an air-source heat pump consolidates heating and cooling into one system that operates at 230–300% efficiency.

Annual savings vs. gas furnace: $200–$600 depending on gas vs. electricity price ratio in your area. After the $2,000 IRA credit and utility rebates: net cost $2,200–$8,000 for most homes. See our heat pump cost guide for full breakdown.

22. Add a Home Battery for TOU Savings

If your utility has time-of-use rates with a significant peak/off-peak spread, a home battery charges at night (cheap) and discharges during peak hours (expensive). In California, with rates up to $0.46/kWh peak and $0.14/kWh off-peak, a 13.5 kWh battery saves $800–$1,200/year in electricity costs.

After the 30% IRA Section 25D credit (no cap), a single Tesla Powerwall 3 costs $6,650–$8,400. Payback: 7–10 years in high-TOU markets.

See our home battery backup guide and best home battery systems for details.

23. Install Solar Panels

Solar eliminates 70–100% of your electricity bill depending on system size. Cost: $18,000–$30,000 for a 8–12 kW system, reduced to $12,600–$21,000 after the 30% IRA credit. Payback: 6–10 years in most markets.

24. Go All-Electric (Electrification)

Replacing gas appliances (furnace, water heater, stove) with electric heat pumps and induction cooktops — powered by solar — can reduce combined utility bills by 50–80% in many climates. This whole-home electrification approach maximizes IRA credits across all categories.

25. Conduct a Professional Energy Audit

A BPI-certified auditor with a blower door test and thermal camera identifies exactly which of the above projects will have the highest ROI for your specific home. Cost: $300–$600, reduced to $150–$450 after the $150 IRA audit credit. Most homeowners who complete a professional audit and follow through on recommendations save $500–$1,500/year.
