According to the U.S. Energy Information Administration (EIA), for a price premium of $350, U.S. consumers can buy a refrigerator or freezer that will use 35% less energy over its lifetime (compared to a base model). But, the relationship between incremental cost increase and energy savings is not a linear one.
What does this mean?
For just $50, your refrigerator could cost 20% less to operate.
This cost/savings discussion is the main focus of the EIA's recently published analysis of the incremental cost of energy efficiency. According to their data, consumers might only need to spend $50 more on their new refrigerators or freezer to realize significant energy savings.
