What if your home could be programmed to save you money every chance it got?

Energy saving smart devices are no longer a thing of the future. The recent eruption of smart home technology has given us everything from smart lights that turn off automatically to smart power strips that can “unplug” devices not in use.

Smart home technology marries two popular topics of the moment: green technology and the internet of things.

There are several smart home devices that are popular today and known to save energy. We examined claims made by several popular device manufacturers and crunched the numbers to find out, on average, what each device should save a homeowner per year.

Your Home’s Energy Usage

The average home in the United States spends around $3,052 per year on utilities. Knowing what parts of your home use (and waste) the most energy can help you cut costs by investing in smart home technology.

According to the U.S. Energy Information Administration, 42 percent of the average home’s energy is used heating a space; another 18 percent is used heating water. Refrigeration, cooling and lighting each account for 5 percent of the average home’s energy usage. (24 percent of a home’s energy is unaccounted for in their study).

Smart Home Technology That Can Save You Money

To find out the average breakeven price, we averaged the prices of the three most popular products to determine the average price for the device. Our methodologies for each device are listed below.

Smart Shower: The Evadrop shower head claims to save up to 50% of your water. The Nest cites the average water consumption for a family of four at 100 gallons per day, which can cost as low as $34 per month in Phoenix and as high a $65 per month in Boston. 50 percent of the average of those two numbers puts the average savings from using a smart shower at $22 per year.

We went with a conservative 15 percent energy savings. The U.S. Department of Energy reports that the average U.S. household spends about $3,052 per year on utilities with about 48 percent of that being heating and cooling. This equals $1,464 a year spent on heating and cooling. 15 percent of that number puts us at $219 saved per year.

Occupation Detectors and Motion Sensors: reports that using new lighting technologies can reduce lighting energy use in your home by 50 percent to 75 percent. If lighting energy is 11 percent of the average home’s energy budget and the average home spends $3,052 per year, then $355 a year is spent on lighting. 50 percent of that number is $167.

The top occupation detectors/motion sensors are The Samsung SmartThings Motion Sensor ($39.99), the Ecobee Room Sensors ($79) and the Insteon Motion Sensor II ($39.99).
