4. Buy a Dishwasher

Washing your dishes by hand may seem like the most cost-effective way to get your dishes clean, but in actual fact you use much more water and much more electricity to heat the water than you may think. Dishwashers are designed to be economical in their use of both water and electricity and it will save you time and money in the long run; not to mention avoiding the bun fight after dinner as whose turn it is to do the dishes. Pack the dishes in 5 minutes, put the kettle on and enjoy an extra hour to yourself in the evening and wake up to a clean kitchen.
