This study is based on a series of surveys answered by 200 consumers from four cities in the State of Guanajuato, Mexico.

In some cases, photographic evidence was gathered from the consumers’ refrigerators to represent the typical usage habits. In general, the results show that better usage habits are necessary from an energy point of view. Most consumers agree with adopting best practices for using their refrigerator.
