Which appliances are commonly referred to as energy hogs?

Refrigerators and freezers are commonly referred to as energy hogs because they typically consume a significant amount of electricity in both residential and commercial settings. These appliances are designed to run constantly to maintain proper temperatures for preserving food, which contributes to their high energy usage. Advances in technology and design have led to improvements in energy efficiency, but older models can consume even more power, making them standout examples of energy-intensive appliances.

While washing machines, dishwashers, ovens, and microwaves do use energy, they typically do not run continuously, and their overall consumption is less significant compared to that of refrigerators and freezers. Heating units and air conditioners can also consume a large amount of energy, particularly in extreme weather conditions; however, refrigerators and freezers maintain a constant level of energy usage throughout the day, which is a primary reason they are specifically highlighted as energy hogs.
