19 Smart Ways to Slash Your Electric Bill

To effectively slash your electric bill, focus on optimizing heating/cooling (like adjusting thermostats and sealing air leaks), reducing water heating costs (like using cold laundry cycles), and upgrading lighting and appliances (switching to LEDs and ENERGY STAR-rated devices). These methods can reduce usage by 10–40%, saving hundreds annually.

That’s exactly what the 19 tips below are built around. Instead of throwing random “save energy” advice at you, this list targets the biggest bill drivers first: thermostat control and airflow leaks, hot water habits, always-on electronics, and the way you schedule high-watt appliances. I’ll go through them one by one so you can start with the easiest changes today, then move into upgrades like LEDs, smart plugs, and ENERGY STAR options when you’re ready.

1. Adjust the Thermostat

Setting your thermostat 7 to 10 degrees higher in summer or lower in winter for at least eight hours a day can cut your annual heating and cooling costs by up to ten percent. Heating and cooling are usually the largest energy expenses in a home, so even small adjustments make a noticeable difference.

Programmable and smart thermostats help maintain consistent settings throughout the day without requiring manual changes.

2. Unplug Idle Electronics

Electronics and appliances continue to draw power when turned off. This standby consumption is often called “vampire load” and can account for up to ten percent of a household’s electricity use.

Unplug items that are not in use, group devices on power strips, or use smart plugs that automatically cut power when devices are idle.

3. Reduce Hot Water Use

Water heating uses a significant amount of energy. You can reduce this cost by shortening showers, using cold water for laundry, and lowering your water heater temperature to around 120 degrees Fahrenheit.

Repairing leaky faucets and using efficient showerheads also helps reduce unnecessary hot water use.

4. Run Appliances During Off‑Peak Hours

Many utility companies offer lower rates during off‑peak times such as late evening or early morning. Running high‑energy appliances like washing machines and dishwashers during these hours can lower your monthly bill.

Use built‑in delay timers or scheduling features to shift usage without changing your routine.

5. Air‑Dry Clothes and Dishes

Dryers and dishwasher heat‑dry settings consume large amounts of electricity. Air‑drying clothes when possible and turning off the heat‑dry setting on your dishwasher can noticeably reduce energy use.

6. Track Your Energy Use

Keeping an energy diary or using a kilowatt meter helps identify which appliances use the most electricity. Monitoring actual consumption allows you to focus on the habits and devices that impact your bill the most.

This step also makes it easier to decide where to invest in upgrades later.

7. Limit Standby Power

Gaming consoles, televisions, computers, and routers often remain in standby mode unless fully powered off. Turning them off completely when not needed prevents continuous energy draw throughout the day.

8. Run Full Appliance Loads

Dishwashers and washing machines use the same amount of energy whether they are full or half full. Running them only when full helps reduce total cycles and cuts unnecessary energy and water use.

9. Use Smart Plugs

Smart plugs help control appliances and electronics automatically. They cut power to devices that are not in use, which reduces standby consumption.

They also allow you to schedule usage directly from a phone or home automation system.

10. Install a Smart Thermostat

Smart thermostats learn your schedule, adjust temperatures when you are away, and help avoid wasteful heating and cooling. This upgrade alone can reduce annual energy costs by about ten percent.

11. Switch to LED Lighting

LED bulbs use up to seventy‑five percent less electricity than incandescent bulbs and last far longer. Replacing older bulbs with LEDs throughout the home can save the average household around two hundred twenty‑five dollars each year.

12. Use Ceiling Fans

Ceiling fans help with air circulation and reduce the load on your cooling and heating system. In warmer months, they create a cooling effect that allows you to raise the thermostat without losing comfort. In cooler months, reversing the fan direction helps distribute warm air more evenly.

13. Seal Windows and Doors

Small gaps around windows, doors, and baseboards allow conditioned air to escape. Sealing these areas with caulk or weatherstripping improves indoor temperature control and reduces the strain on heating and cooling systems.

14. Improve Insulation

Adding or upgrading insulation in attics, basements, and walls helps keep your home at a stable temperature. Better insulation reduces how often your heating or cooling system needs to run, lowering electricity consumption.

15. Install Dimmer Switches and Motion Sensors

Dimmer switches let you reduce lighting levels when full brightness is not necessary. Motion‑activated lights prevent energy waste in rooms that are often left lit unintentionally, such as hallways and garages.

16. Check for Duct Leaks

Leaky ductwork reduces the efficiency of heating and cooling systems. Sealing and insulating ducts ensures that warmed or cooled air reaches the intended rooms without loss.

17. Upgrade to ENERGY STAR Appliances

ENERGY STAR‑certified appliances use less electricity than standard models. When it is time to replace a refrigerator, washing machine, dishwasher, or HVAC unit, choosing an efficient model can cut long‑term operating costs significantly.

18. Use Utility Rebates and Incentives

Many utility companies offer rebates for buying efficient appliances, improving insulation, or installing smart thermostats. These incentives help offset the cost of upgrades and speed up return on investment.

The ENERGY STAR Rebate Finder can help you locate available programs in your area.

19. Schedule a Home Energy Audit

A home energy audit identifies the areas where your home loses energy and the improvements that will have the most impact. Many utility providers offer audits for low or no cost.

Audits give personalized recommendations to reduce electricity waste based on your home’s layout and condition.

Additional Tips for Seasonal Energy Savings

Electricity use often increases during extreme weather seasons. These adjustments help control costs throughout the year.

In Winter

1. Lower the thermostat slightly and wear layered clothing indoors.
2. Let sunlight in during the day by opening curtains on south-facing windows.
3. Close curtains and blinds at night to retain indoor warmth.
4. Use draft blockers at the base of doors to prevent cold air from entering.

In Summer

1. Keep blinds or curtains closed during the hottest part of the day.
