Cutting the number down

Skipping heated dry and cracking the door open is the largest single saving available on a dishwasher, and it costs nothing.
A full load uses the same energy as a half load, so waiting until it is full halves the per-dish cost.
Pre-rinsing under a hot tap usually spends more energy heating water than the machine would have used.
