With temperatures approaching 100 degrees already, my husband and I are keeping a close watch on the electric bill.
Previously, we added insulation to the attic and installed double-pane, energy-efficient windows. Now we have ordered a big, new EnergyStar refrigerator and retired our second fridge--an energy hog kept in the sweltering garage.
That purchase got me thinking about our energy budget. What part of running our home costs the most? Curiously, I got differing answers when I consulted the Department of Energy's Energy Savers Booklet and the book, Energy Efficient Homes for Dummies.
For example, the former lists space heating as using 31% of the average utility bill, while the latter estimates it at 47%. The former gives water heating 12%; the latter 21%. The numbers for refrigeration were closer: estimated at 8% and 5%.
Regardless of who is right, I hope that getting the high-efficiency fridge (with stylish LED lights that keep the interior cooler) and ditching the one in the garage will give us tasty savings within a few years.
