Energy use or water use? If you just run the hot tap the whole time you're washing dishes then maybe you could start to compete with a mostly empty dishwasher. But if you wash with cold water and use only the water necessary, there's no fucking way a dishwasher uses less water or less electricity than that.
Efficient for what though?
