Blogging Away Debt made this graph to show how much their family reduced energy consumption by installing compact fluorescent light bulbs and unplugging a freezer in the basement. The chart shows a decrease of around 2-3 average kilowatts hours per day, resulting in electrical bills that were about a half as much as before.
A Few Changes Made a Big Difference in Our Electric Bill [Blogging Away Debt]







Hmm..that post didn’t show my greater than or less than signs…
@speedwell: Thermastor makes the most efficient self-contained models, but you’ll pay some serious $$ for the privilege. They’re quiet too. If you go to [www.energystar.gov] ,they have an Excel spreadsheet of Energy Star rated dehumidifiers, with energy ratings. You can then use Excel to sort them by efficiency.
Not sure what climate you’re in, but if you’re in a warm, humid climate such as Florida, it’s better to get a split-system dehumidifier, where the humidity goes down the drain and the heat gets pumped outside. These are a bit difficult to find, but can easily be made by splitting a dehumidifier so the cold coil’s inside and warm coil’s outside. In very humid climates, you can build a great dehumidifier by installing a small 0.5 to 1-ton AC evaporator coil in the existing AC ductwork, with a 3 ton condensing unit outside. Of course, you’ll need to do some modifications to the components to make them work together and you’ll need someone who actually understands refrigeration to pull it off, but the results are worth it. As an easier alternative, Carrier, Bryant, and Lennox make an integrated central AC/heatpump/dehumidifier system that does the job quite well.
