Appliance Energy Use and Efficiency Guide

Where appliances use power and water, what efficiency labels mean and simple habits that lower running costs.

Appliances account for a large part of a home energy bill. Refrigerators run all day, water heaters hold heat around the clock and dryers and ovens use bursts of high power. Efficiency labels and yellow guide tags show estimated yearly energy use and let you compare models, and an ENERGY STAR mark means a model meets a set of efficiency standards. Older appliances often use noticeably more power than new ones, which matters in a long-term comparison.

Habits matter as much as labels. Clean refrigerator coils and good door seals, full loads in washers and dishwashers, clear dryer vents, sensible water heater temperatures and using the right size burner all cut waste. When you compare repair and replacement, running costs deserve a place in the numbers, particularly for an old refrigerator or freezer. Our energy tool gives you a simple way to estimate what an appliance costs to run.
