Every few years the U.S. Energy Information Administration conducts a survey to determine which household equipment uses the most energy. Results from the 2009 Residential Energy Consumption Survey will be released in early 2011.

Of course, results depend on where you live. The last survey showed the Northeast using the most energy for home heating, followed by a group of lighting and appliances – including dishwashers, clothes washers and dryers, computers and TVs. Water heaters came in at third, followed by refrigerators and air conditioners.

In the South, the appliance and lighting group used the most energy; air conditioners placed second. Heating came in third, followed by water heating, and refrigeration.

Besides updating consumption data, the new survey will provide additional information on home electronic use and energy efficiency.

It will be interesting to see whether much will change in the new report. I predict an increase in the appliance group category. As a group, all of those phone chargers, Wii packages and home wine cellar units must be pulling some serious juice.

Have you noticed evidence of changes in energy consumption in the last few years? Do your customers seem any more interested in green technology, and energy conservation regarding their units? Are those who need units replaced asking about these technologies?
