If you do use a clothes dryer, try to minimize the amount of energy you use. Separate your wet laundry by weight. Dry towels and heavier cottons separately from lighter-weight clothes. Don't over-dry your clothes. If your machine has a moisture sensor, use it, if you’re in the market for a new dryer; consider buying one with a moisture sensor that automatically shuts off the machine when your clothes are dry.
Not only will this save energy, it will save the wear and tear on your clothes caused by over-drying. Clean the lint filter in the dryer after every load to improve air circulation. Use the cool-down cycle to allow the clothes to finish drying with the residual heat in the dryer. Periodically inspect your dryer vent to be sure it’s not blocked. This will save energy and may prevent a fire. Use rigid venting material, not plastic vents that may collapse and cause blockages.
