The bathroom dryer seems to save paper but consumes more electricity. Especially the old-fashioned hand dryer has a much greater impact on the environment than the paper towel.

Although cotton is easily degraded by natural fibers, it is one of the most resource-intensive crops in the world.
The use of water and pesticides is much higher than other crops

The environmental protection bag made of cloth must be used at least 131 times to offset the impact of the disposable plastic bag. However, the environmental protection bag is discarded after an average of 51 times. The water and fertilizer used to produce it are not much at all, and the glass container is produced. Plastic containers consume twice as much energy and generate more greenhouse gas emissions, and discarded glass can be degraded after 1 million years.

In addition, non-recyclable solar cells that consume a lot of water and electricity in the manufacturing process, bioethanol gasoline produced by the conversion process with more greenhouse gases than petroleum, and lithium-ion batteries that generate huge amounts of carbon dioxide emissions during manufacturing are also not so green.
