Using lower heat settings is another easy change. Many modern fabrics dry just as well on medium or low heat, especially when loads are properly sorted.
Drying similar fabrics together makes a big difference. Mixing heavy towels with lightweight shirts forces the dryer to run longer than necessary. Grouping items with similar thickness and moisture levels allows for shorter, more efficient cycles.
Upgrading to a more energy-efficient dryer can provide long-term savings. Heat pump dryers, for example, use significantly less electricity than traditional electric models and are becoming more widely available.
