Some electrical appliances that consume a lot of electricity may be due to the duration of use, the size of the appliance, or the environment in which it is used. For example,

A water heater will consume more electricity when used for a long time because it has to continuously heat the water. In addition, the temperature of the water entering the machine also affects electricity usage. This is because water with a low temperature uses more electricity to heat than water with a high temperature.
A hot air oven, although a convenient cooking device, has a disadvantage of requiring a lot of electricity because it requires a high temperature to cook the food. It takes longer to cook than other methods such as using a microwave or an electric pan.
An air conditioner is a device used to adjust the temperature and humidity in a room. If the air conditioner is used all the time for a long time, it will use more electricity. In addition, installing the air conditioner in a place with a high temperature or hot weather will make the air conditioner work harder to maintain the temperature and humidity as desired by the user.
