Wash only full loads
Cut one load of wash per week, even if you're already using cold water only, and you could save $18 a year on your laundry costs.
Use cold water
Cold water cleans your clothes just as well as hot water in most situations. Switch to cold for three loads a week and you could save up to $22 per year on your energy bill.
Throw a dry towel in the dryer
A dry towel added to your dryer load can significantly reduce drying times. If you're doing seven loads a week this could save you $27 a year.
