Start by checking your rate and recent kWh history, then adjust energy use or its timing where it matters. Fixed monthly charges generally remain even when you use less electricity, and budget billing smooths payments rather than reducing the amount of electricity you use.
Start with your bill: find out what can change
Look for your rate name, electricity use in kilowatt-hours (kWh), any demand measurement, fixed monthly charges, and the chart of past usage. Your utility may also provide hourly or 15-minute interval data. These details help you choose an action that fits your actual rate instead of relying on generic savings claims. The U.S. Department of Energy explains the main rate components in its guide to evaluating utility rate options.

- Energy charges: Charges based on kWh used. Using fewer kWh can reduce this part of the bill.
- Time- or season-dependent prices: The price per kWh may vary by time of day or season. Shifting flexible electricity use to a lower-priced period may help if your rate has these terms.
- Demand charges: Some rate schedules charge based on the highest measured demand during a defined interval. If yours does, running several large appliances at once may contribute to a higher peak. Not every residential bill has a demand charge.
- Fixed charges: A set charge under the rate schedule. It generally does not fall just because you reduce consumption.
Use your own usage history and, if available, interval data to identify when electricity use rises. The DOE recommends evaluating rate alternatives against the customer’s actual usage; a plan that works for one household may not work for another.

The Federal Trade Commission recommends practical steps for heating and cooling, which can account for substantial household electricity use when HVAC equipment runs frequently. The amount saved depends on your home, equipment, local weather, and habits; no fixed saving is guaranteed.
#1 Best Overall
- Various Monitoring Parameters: The power meter plug can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum power (W), cumulative days and time of your appliances. By switching 7 display modes, you can easily know the various parameters while the appliance is working. The home energy monitor can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time
- Upgraded LCD Display: With large screen size 2.36 inch x 1.85 inch, clearer monitor backlit, our electrical usage monitor can display the data clearer and more visible no matter day or night. 180°full wide viewing angles is great for reading and recording the data in any angles. No need to stand on the front of the display and bend over to read the numbers
- Adjustable Backlight Time: Our upgraded watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=always on), finally press the "COST" to save the backlight time settings
- Overload protection: When the power of the appliance exceeds the overload power, the LCD will display “OVERLOAD” to warn the user. All the buttons will quit working and can only be workable when you lower or remove the load power. The default overload power is 3680W and is adjustable from 0 to 3680W. In general, you need to set the overload power to 1800W before using. Just press the "function" button for more than 3 seconds to enter the setting
- Data Memory Function: The wattage meter will record your power consumption data when you remove it from socket, or remove appliances from the electricity monitor. You can directly see the last data when you use it next time. This function can also automatically save the data when there is a sudden power failure
- Adjust the thermostat when you are asleep or away. Lower it in winter and raise it in summer. A programmable thermostat can automate the schedule; check compatibility with your heating and cooling system before buying one.
- Check forced-air filters. For a furnace, heat pump, or air conditioner, inspect and replace or clean the filter according to the equipment manufacturer’s recommendations.
- Address identified air leaks. Caulk or weatherstrip suitable leaks around windows, doors, and places where pipes or wires pass through walls. Sealing is not a substitute for addressing structural or moisture problems.
These recommendations are from the FTC’s heating and cooling guidance.
Ask about an assessment and assistance before buying upgrades
A home energy assessment can help identify wasted energy and prioritize improvements. The FTC advises: “Do a home energy assessment or energy audit.” Your utility may offer an assessment for free or at low cost, or refer you to a provider. A hired professional assessment may cost several hundred dollars, according to the FTC. Before paying, research the provider and confirm that the assessment will deliver specific recommendations.

Ask your utility or program administrator about rebates, low-interest loans, or other incentives before purchasing equipment. For income-qualified households, the U.S. Department of Energy’s Whole-House Weatherization overview describes audits that consider the building envelope, heating and cooling, electrical systems, and electric-baseload appliances. The ENERGY STAR special assistance directory lists examples of utility programs and advises customers to contact their utility if they do not find a listing. Offerings, administrators, and eligibility vary by location.
In a July 8, 2025 announcement, DOE reported that the Weatherization Assistance Program had served more than seven million households since 1976 and reported average annual energy savings of $372. These are program-level figures, not a forecast or guaranteed saving for an individual household; they do not establish your eligibility or local program terms. See the DOE announcement for the figures.

Ask your utility whether another rate plan fits your usage
You can keep your utility and still ask whether it offers a different rate, such as a time-of-use or dynamic rate. First compare the plan’s fixed and usage-based charges, the times or seasons with different prices, any demand-charge rules, and enrollment or settlement terms. Then compare those terms with your own hourly or seasonal usage, especially whether flexible loads can move away from higher-priced periods.
A different rate is not automatically cheaper. Without your location, rate schedule, and usage pattern, the result cannot be determined. Ask the utility for the current terms and use its comparison tools or your interval data to evaluate the options. The DOE’s rate-options guide outlines this approach.

Know what budget billing does—and does not do
Budget billing spreads payments across months to reduce seasonal payment spikes. It changes payment timing and predictability; by itself, it does not reduce electricity use or annual charges. Ask your utility how it reconciles your actual costs with the budgeted payments, and review the terms before enrolling. The distinction is described in DOE’s discussion of customer incentives and rate design.
