You do not use a dryer to dry clothes.
First, you hand wash clothes to save energy. Second, you hang clothes out on the balcony to dry them under the sun. All your clothes are done in just a few hours and you do not have to worry about the dryer ruining them.
You can cook any dish with a pan and a rice cooker.
We do not have ovens and toasters at home. They use a lot of energy and the food they make is not healthy. Besides, a rice cooker and a pan are less time-consuming than an oven. There is no need to buy baking utensils and ingredients, and we do not even have to boil the hot water to cook rice, meat, vegetables, pasta soup, and potatoes.
