Handwash Carefully
If done properly, washing dishes by hand tends to be more energy-efficient than using a dishwasher, especially for small volumes of dishes. Instead of washing under a running faucet, put a plug in the sink, or use a large, plastic bowl. And to minimize the amount of water used when rinsing, install a low-flow aerator on your kitchen sink faucets. When washing dishes by hand, minimize the number of times you need to change the water by washing the least-dirty items first.
