Reduce your reliance on appliances. In the old days people didn't need large appliances to run their households; experiment with ways to use only what you really need. Using fewer appliances can make some tasks more time-consuming, but if you get the whole family involved you won't be spending too much extra time on chores.
Most people wash their clothes more than necessary; try reducing the number of loads you do each week.
Hang a clothesline in the backyard and let your clothes line dry instead of using the dryer.
Wash your dishes by hand (using the water conservation method) instead of using the dishwasher.
Limit your baking to one day a week, during which you make several dishes within the same period of time. This way you won't have to heat the oven over and over.
Get rid of small appliances you don't really need, like plug-in air fresheners. Open the windows instead!
