Yeah it is..if you're hand washing with the tap on full blast.

  I bothered to look it up and edited my original comment with citations. TL;DR the dishwasher wins in most cases.

  A dishwasher in the normal cycle uses about as much water as an efficient person uses in washing a single large pot without the tap running (reusing this water for washing all dishes is the most efficient way to hand wash) In addition, a dishwasher has high pressure pumps, a centrifugal grinder, and its own water heater (to heat hotter and more localized than a central water heater, above sanitizing levels)

    The assumptions here are wrong because they are based on creating sanitary dishes suitable for human foodstuffs. Recyclables don't need to be sanitary -- just free of large amounts of dirt. * You don't need rinse water, so the total water needed is at least halved. Since the water is just sitting in a bucket, you can do many, many washings with the same water which increases that efficiency even more. * You don't need heated water as sanitation and complete cleanliness is unimportant. Heating the water alone uses more energy than everything else put together. * You don't need particularly clean water, just clean enough to prevent large dirt from adhering. As such you could use floor-cleaning chemicals that clump the dirt and precipitate it to the bottom increasing use time. Reusing water and the chemicals in that water for longer has a very large impact on the environment. * a couple strokes with a bottle brush take way less energy than a high-pressure pump and once again, get the item clean enough. * Fewer things going through your dishwasher increases its lifespan and decreases the total cost of operation. This is also better for the environment
