Green Collar Careers - Residential Energy Profile

Residential Demand Management begins with understand where the power goes.  The Department of Energy performs studies on the average consumption profile for homes in America on an annual basis.  While many new energy efficient homes and appliances are increasing among the population the overall changes from year-to-year are small. 

Chart 202 below illustrates the latest figures broken down into the 7 major appliance groups:

From the chart two appliance classes of power consumption stand out:

  • HVAC at 31.3%
  • Kitchen Appliances at 26.7% (Roughly 14% of the total bill is just to run the refrigerator)

Those two classes account for 58% of the total power used in the average household.  Other equipment is a general range of anything from pool pumps, to waterbed heaters to vacuum cleaners to tools and outdoor appliances.  At 10.2% this is probably one of the most difficult classes to manage due to the variety. 

Not all homes have electric water heating so the 9.1% figure is an average of averages; roughly half the households have electric water heat, and in those homes water heating may account for 18.2%, where homes do not have electric water heat the figure would be zero.

Lighting takes up an average of 8.8%.

Home electronics are things like television and entertainment systems, personal computers, clocks, and communication hardware, with an average of 7.2 %.

Laundry Appliances share a similarity with water heating; some homes have electric dryers, some do not so the overall average of 6.7% includes both cases.

Again, this is a national average but provides an excellent baseline to begin with.
