The wattage of appliances (equipment) and the amount of operating time can vary greatly. The following information will show how to determine where the energy dollars are going in your home.
Step 1
Look on your utility bill and find the cost per kilowatt-hour (kWh) that is charged in your area. If you cannot locate a bill, rate information can be found by logging onto your cooperative’s Web site or by giving them a call.
Step 2
Since the wattage of an appliance (equipment) determines the electrical usage per hour, the second step is to determine the wattage.
The wattage of an appliance is found on the serial plate. But it is possible that the electrical requirements will be expressed in volts and amperes, rather than watts. If so, multiply volts times amperes to obtain the wattage; e.g. 120 volts x 12.1 amperes = 1,452 watts.
Step 3
Use the following formula to estimate usage and cost.
Watts (Divided By) 1000 = Kilowatts (KW)
KW x Rate $ per KWh = Operational Cost per Hour
To determine monthly cost:
Operational Cost per Hour X number of hours operated per day X number of days in the month = monthly cost
To determine yearly cost:
Operational Cost per Hour X number of hours operated per day X 365 days in a year = yearly cost
Swimming Pool
The filter pump runs continuously in most cases during the summer months. The horsepower rating on the motor usually ranges from .5 to 1.5 and can use 360 to over 1,000 kilowatt-hours per month. Utilize a timer to reduce the pumps operational time.
Ceiling Fans
Ceiling fans and portable fans can help make you feel cooler, but they don’t cool the room. Use them wisely; when you are not in the room, turn them off. Conversely, most ceiling fans have a reversing switch. This can be very effective in moving warm air from the ceiling in the winter and redistributing it throughout the room.
Weather
Many of the appliances/equipment we use in our lifestyles are directly tied to the weather. As the seasons change – causing the temperature to turn cooler or warmer–it usually has a direct effect on our air conditioning and heating use.
Hot Tubs
Although there is nothing more soothing than sinking into a hot tub after a long day, these energy wasters are nothing more than a huge water heater with an open face. Many times, owners don’t even take the time to cover them up when not in use. Hot tubs can use $25 to $50 of energy per month or more.
Closing Off Vents
Perhaps you have unused rooms where you shut off the vent damper thinking you will save electricity by not heating or cooling that room. What you have really done is created an “unbalanced pressure” situation which will result in less efficient operation due to short cycling of the furnace or heat pump and blower. In the case of a gas furnace, this situation could introduce carbon monoxide into the home through back drafts. Rather than closing off vents, consider adjusting the thermostat temperature up in summer and down in winter.
Space Heaters
Most space heaters are 1500-watt units that are used to “warm up” a room such as a bathroom or used temporarily while you work in an unheated garage. A typical space heater used just two hours per day can account for 90 kilowatt-hours of electricity in a month’s time.
Replacing Major Appliances
Age – Sometimes it is hard to justify replacing a major appliance for efficiency reasons until the unit dies. When replacing major appliances, look for the Energy Star label.
Location – If you do replace an older major appliance that is still working, please think twice before putting that older unit somewhere else like in the garage or basement. Freezers and refrigerators are designed to be placed in 70ºF-conditioned areas. Putting them outside in a garage that gets uncomfortably hot in the summertime just causes the refrigerator or freezer to run more often. In addition, these places aren’t always the cleanest, so the coils collect dust, pet hair, etc., quicker than in the house, which affects their efficiency.
Air Leaks – It’s been estimated that a typical home with all of its foundation and wall cracks, holes around sink plumbing and electrical outlets, gas and fireplace flues, and use of recessed can lighting in ceilings have air leakage that it is equivalent to leaving a door open year-round. Take the time to seal all of these openings with caulk or foam and apply insulated foam gaskets behind outside wall switches and receptacles. Add sufficient insulation where needed in attics and walls.
Using Energy-Efficient Heating and Cooling Systems – If you have heating and cooling units that are more than 15 years old, consider replacing them with energy-efficient units. Great strides have been made in improving the energy efficiency of heating and cooling equipment. If you use evaporative cooling systems (swamp coolers), follow the manufacturer’s recommendations regarding maintenance items such as pads, water changes, etc. Do not operate them simultaneously with refrigerated air conditioning systems and remember to close windows and doors when switching to refrigerated-type systems. Also, cover the evaporative coolers when not in use to eliminate air leaks through them. Talk with your electric cooperative about what is available.
Shut the door – Every time the entry doors are opened during heating and cooling seasons, unconditioned air from the outside enters the home, which has to be heated or cooled. Try to reduce these door openings to a minimum.
Keep Records
Keep records for a few months each season. Learn how changes in your activities can affect your energy budget. Use Less Energy Make changes to how you use your energy.
Use Less Energy
Make easy changes first. Here are some ideas to get you started.
- Set thermostats for energy economy – Make changes in temperature levels gradually so you and your family can adjust – It is estimated that a 1º F temperature change can reduce heating and cooling costs by 2 to 3% – By installing a programmable thermostat, changes such as these require minimal effort
- Keep heating and cooling systems working more efficiently by replacing filters monthly and having your system serviced annually
- Turn off lights whenever possible
- Use energy-efficient lighting such as T-8 fluorescent lighting, compact fluorescent lighting, and high-pressure sodium lighting to cut lighting costs by up to 75%
- Lower the temperature setting on your water heater to 120º F
- Fix hot water faucet leaks
- Reduce phantom loads
Other Sources of High Usage
Sometimes you’ll find equipment using electricity that you thought was turned off. It could be a faulty motor control on an air conditioner, well pump, or pool pump, a leaky hot water faucet, or lights and equipment simply left on. By comparing your use with that in the Appliance Energy Use Guide tables, you may determine whether that equipment is using an unusually high amount of electricity.
However, if you can’t find the problem, contact your electrician or seek proper advice from your electric cooperative.
You can do something about how you and your family use energy. A big, first step is tracking current energy consumption.
Meter Reading Dates
A factor that enters into higher than normal electric bills is the number of days between meter readings. Check the number of days in your billing cycle and the average number of kilowatt-hours used per day to make accurate comparisons. Many people often overlook this important consideration.
It’s important to read your meter on the same day of each month. If you notice that your usage has increased substantially from one month to the next for no apparent reason, you will be able to diagnose equipment failure sooner.
Is the Meter Accurate?
The electric meter is often accused of inaccuracy, but it’s seldom the culprit. Your meter does not lie. When it records more electricity being used, try to find out why by looking at your family’s activities during that period…was the weather warmer or colder than normal? Was it a washday? See what activities, if any, can be altered to use energy more wisely.
The meter is a finely calibrated, highly accurate device used to measure power use. Your electric cooperative has a continuing program to test the accuracy of all its meters to assure that you are being billed for the exact number of kilowatt-hours used. All meters are tested on a regular basis. Historical data bears out the fact that in more than 99% of the cases, the electric meter is accurate. High bills are almost always traced to other causes.
In addition to vacations, take a look at some of the seasonal uses for electricity that may cause an increase in consumption. These include crop dryers, air conditioners, portable heaters in the garage or basement, engine heaters that keep your vehicles ready to run, holiday lighting, heat tape to keep pipes from freezing…. the list goes on and on.
Also, don’t forget about hobbies or businesses that operate out of the home.
When vacation time comes and you’re planning to be gone for a couple of weeks, your electric bill should decrease significantly, right? Wrong!
Many people believe that when they leave for vacation, their electric meter stops until they return. Ask yourself a few questions before assuming your electric bill should decrease by any considerable amount during vacation.
First, was your heating or cooling system turned off or the thermostat set up or down in your absence? If these preparations are not made before you leave, your heating and cooling system will work to maintain your thermostat’s preset temperature even if no one is at home.
Second, was the water heater turned down or off while you were gone? If the electric water heater is left energized during vacation, it will continue to operate and maintain the tank temperature even if you’re not using any hot water. Were the refrigerator and freezers emptied and turned off? If not, they will continue to operate to maintain the preset temperatures.
Perhaps you can make arrangements with a neighbor to keep an eye on your place and adjust the heat and/or air conditioner and water heater shortly before you return. In addition, you may wish to unplug all appliances not in use. If a light is to be left on, it should be connected to a timer.
Also, many vacationers bring home several days or weeks of laundry. This will give your electric water heater and washer and dryer a workout your first day or two back home.
The wise use of appliances can have a positive effect on your energy consumption. Ask yourself these questions:
- Do I turn off lights and ceiling fans when a room is not in use, or do I leave them on?
- Does the television set entertain the entire family, or does it entertain an empty room?
- Do I leave my computer and peripherals on for extended periods of time when not in use?
These are prime considerations that affect the amount of electricity you use to maintain your lifestyle.
Did You Know?
The new big-screen TVs and plasma TVs are great for watching your favorite movies or sports network. But they can use as much as 850 kilowatt-hours per year.
