Dishwasher vs Hand Washing Cost
Compare water and energy cost of dishwasher versus hand washing per cycle
Modern dishwashers are more efficient than hand washing for full loads, using roughly 13 litres of water per cycle vs 40-65 litres for hand washing.
💡
Tip: Only run a full dishwasher - half loads at full water and energy consumption halve the efficiency advantage over hand washing.

Fun Fact
A University of Bonn study found hand washing uses on average 4x more water and 2x more energy than an efficient dishwasher.
