To know about the energy consumption of household appliances we must know that they are classified by ranges, white, brown and gray. While the classifications are sometimes very strict, at other times the differences are minimal. Thus, within this line we would include all those appliances that we could define as “classics” within the kitchen, home cleaning and laundry, that is, it refers to large appliances that are related to cleaning tasks in the kitchen, such as a washing machine, refrigerator, tumble dryer, dishwasher and oven. Small appliances such as toasters, kitchen robots and everything related to personal hygiene would be out of this list.
