Top five energy users in your home

A starting point for savings

By Anne Prince

While most homeowners would like to be more energy efficient and save money, often it feels overwhelming because many people don’t know where to start. How can the average family use less energy, lower their utility bill and still meet their daily energy needs? To help jumpstart your effort, it is useful to know what the top energy users are in your home. With this knowledge, you can choose a path that works best for your family.

According to the U.S. Energy Information Agency, the top five energy users in U.S. homes are:

  1. Space cooling
  2. Space heating
  3. Water heating
  4. Lighting
  5. Refrigeration

Adjust the temperature

Together, home heating and cooling use the most energy and take the biggest bite out of your energy budget. On the bright side, there are ways you can achieve at least 10 percent savings by taking a few simple low-cost or no-cost steps.

  • During cold weather, set your thermostat to 68 degrees Fahrenheit.
  • During warm weather, the recommended indoor temperature is 78 degrees Fahrenheit.
  • Cleaning the filters of your HVAC system can cut costs from five to 15 percent.
  • Clean the coils around your electric baseboard heater to maintain maximum efficiency.
  • Caulk and weather-strip around windows and doors to prevent heat from escaping to the outdoors.

No matter what the climate or time of year, proper use of a programmable thermostat can save you 10 percent on your monthly utility bill.

Shine the light on savings

Take a fresh look at the lighting in your home. If you still use incandescent lighting, your light bulbs are operating at only 25 percent energy efficiency. Replacing your home’s five most frequently used bulbs with Energy Star-certified LEDs can save you $75 per year. Another easy way to save is to always turn lights off in rooms that are not being used.

Water heating efficiency

Just as it is energy-wise to insulate your roof, wall or floor, it also pays to wrap your hot water heater with an insulating blanket. This is all the more critical if you have an older unit. Make sure to follow the manufacturer’s instructions. For additional efficiency and savings, insulate exposed hot water lines and drain one to two gallons of water from the bottom of your tank annually to prevent sediment build-up.

Put cold hard cash back in your wallet

If your refrigerator was purchased before 2001, chances are it uses 40 percent more energy than a new Energy Star model. If you are considering an appliance update, a new Energy Star refrigerator uses at least 15 percent less energy than non-qualified models and 20 percent less energy than required by current federal standards. Regardless of the age of your fridge, there are additional steps you can take to save energy and money. For example, don’t keep your refrigerator too cold. The Department of Energy recommends temperatures of 35 – 38 degrees Fahrenheit for the fresh food compartment and 0 degrees Fahrenheit for separate freezers (used for long-term storage).

By understanding how your home uses energy, you can determine the best ways to modify energy use and keep more money in your wallet. For additional ways to save, visit our energy page or contact your local electric cooperative.
