大部分烘干机用天然气,当然也用电点来转滚筒,但是用不了多少电和天然气。就是因为便宜 (不到25美分一次),所以大部分美国人用烘干机。
In most areas, natural gas and propane are less expensive than electricity, so it costs approximately half as much to dry a load in a gas dryer versus an electric one. Gas dryers typically cost 15 to 25 cents per load to dry, whereas it may cost 30 to 40 cents per load in an electric dryer.
