Don't waste water by prerinsing. Position the refrigerator out of direct sunlight. Microwave ovens and crockpots are more efficient for heating small quantities of food. Wash clothes with warm water and rinse with cold water. Use non-phosphate laundry detergents.
Air drying is the most energy-efficient procedure.
Install water-saving showerheads and faucet aerators. Take short showers rather than baths. Repair leaky faucets and toilets. THE HOME Minimize the use of pesticides. When you do use them, follow the label directions carefully.
