18. Enjoy your dishwasher
If you have a dishwasher and think of it as a luxury just for when you have company and a lot of dishes to wash, think again. Go ahead and use it — frequently. Dishwashers tend to use much less water to clean dishes than we humans do, and if you’re washing with hot water, that means they require less heated water, saving you money. For maximum savings, wait until the dishwasher is full before running it.
