Wash your laundry in cold water to save on your electricity bill. I promise your clothes will be just as clean.
Every load you wash with hot and rinse with warm will cost you about $0.68, but if you wash and rise with cold each load will only cost you about $0.04, which is quite a difference, especially if you have a large family like me!
You will also want to make your own detergent: Homemade Laundry Detergent.
NO MORE BUYING LAUNDRY DETERGENT!!!!!!!!!!!!!
And then if you want to take it a step further and save even more money you can sun dry your clothes! It can make your clothes last longer ( your dryer will weaken the fabric and your clothes will need replacing sooner.
