Environmental impact

Due to the increasing cost of repairs relative to the price of a washing machine, there has been a major increase in the yearly number of defective washing machines being discarded, to the detriment of the environment. The cost of repair and the expected life of a machine may make the purchase of a new machine seem like the better option.

Different washing machine models vary widely in their use of water, detergent, and energy. The energy required for heating is large compared to that used by lighting, electric motors, and electronic devices. Because of their use of hot water, washing machines are among the largest overall consumers of energy in a typical modern home.

Washing machines worldwide release around 62 million tonnes of carbon dioxide equivalent in a year. However, modern improvements have been made aiming to lower these emission numbers, and it depends on the user's choice to fully determine their environmental impact.
