What is one item in your home that could be made to be more efficient, and how would you make it more efficient?

One item in my home that could be made more efficient is my refrigerator. I would make it more efficient by organizing the contents in a way that maximizes space and allows for better airflow. This could involve rearranging items to ensure that the colder air circulates more effectively, as well as rotating food items to prevent any from being forgotten and spoiling. Additionally, I could set the temperature to the optimal level for both food quality and energy efficiency. Regularly cleaning the coils and keeping the door seals tight can also help improve the efficiency of the refrigerator.
