Turn down your thermostat.
For every degree you lower your heat in the 60-degree to 70-degree
range, you will save up to 5% on heating costs. Set the thermostat
back to 55 degrees or off at night or when leaving home for an extended
time to save between 5-20 percent of your heating costs. http://www.consumerenergycenter.org/flex/tips.html
Use appliances efficiently. Do only
full loads when using your dishwasher and clothes washer. Clean your clothes dryer's
lint trap after each use. Use the moisture-sensing automatic drying setting on your
dryer if you have one. http://www.ase.org/powersmart/docs/cmclean.html
When buying new large appliances, choose
Energy StarŪ-certified models. For example, a new Energy StarŪ-refrigerator
uses about 20% less energy than a standard new refrigerator, and 46% less than one made in
1980. A new Energy StarŪ clothes washer uses nearly 50% less energy than an
standard washer. http://www.consumerenergycenter.org/homeandwork/homes/inside/appliances/index.htm
Reduce hot water temperature.
Set your water heater to the "normal" setting or 120° unless
the owner's manual for your dishwasher requires a higher setting.
Savings are 7-11% of water heating costs. http://energyoutlet.com/res/waterheat/waterheater.html
