The other big users of energy in your household are your hot water heater, your washer and dryer, and your dishwasher. Each, in its own way, can be inefficient. Here are some things to try:
Either turn the hot water heater down a couple of degrees, or turn on the “energy conservation” setting.
Buy insulation for your hot water heater at a local store and insulate the pipes as well.
Install a timer on your water heater to turn off at night and just before you wake up in the morning.
When possible, wash a few dishes by hand. Over time, that will save a few loads in the dishwasher, conserving energy.
Don’t pre-rinse dishes. Today’s detergents are powerful enough to do the job.
Wait until you have a full load to run the dishwasher.
Wash clothes in warm water, not hot. The clothes will be just as clean, and you’ll cut energy use by 50 percent.
Don’t over-dry your clothes. That will save 15 percent.
