Running my dishwasher twice as much uses much less power each month than 24U of computers upstairs. It's not really that much in the scheme of things.

I've run my full size dishwasher with a single cup, single bowl, and single spoon in it. More than once.

It's a machine. It's okay to use it.

Ah yes, wasting energy is totally okay as long as there is something else that uses more energy.

So long as Google runs a huge fleet of servers, I sleep with all lights in my house on.

Dishwashers are about not wasting my time and energy, I couldn't care less about water or power savings.
