The amount of water saved by not using a clothes dryer is negligible, as water is not typically used in the drying process. Clothes dryers use heat to evaporate the moisture in the fabric, and the water vapor is then expelled through a vent. The water is not collected or reused in most standard residential dryers.
However, it is worth noting that using a clothesline or drying rack instead of a dryer can save energy. By air-drying your clothes, you reduce the electricity or gas consumption associated with running a dryer. This can have a positive impact on your utility bills and overall energy consumption.
It's important to consider the environmental impact of your laundry routine beyond water usage. By air-drying your clothes, you can conserve energy, reduce greenhouse gas emissions, and extend the lifespan of your clothing by avoiding the potential wear and tear caused by dryers.
