Are electric dryers or gas more energy efficient?

Gas dryers are generally more energy-efficient than electric dryers, as they use less energy to dry clothes. On average, gas dryers use about 20% less energy than electric dryers. This is because gas dryers generate heat directly, while electric dryers use electricity to generate heat through a heating element. Additionally, gas dryers can also take advantage of the heat generated by the burner to preheat the incoming air, which further increases their efficiency.
