When doing yard work, try to use lawn rakes, non-motorized push mowers, and hand edgers.
Try to use simple environmentally sound substitutes for cleaning and for pest control (e.g., vinegar, baking soda, and borax). Use all household products and insecticides according to the manufacturer's directions.
Compost your yard wastes.
When you barbecue with charcoal, start the charcoal with an electric or chimney-type fire starter instead of using lighter fluid.
Insulate your home, it will reduce summer cooling costs and winter heating bills.
Caulk and weather strip your doors and windows.
Use ceiling fans rather than air conditioning whenever possible. Try to set the thermostat for your home air conditioner at the lowest setting that is comfortable.
Close off unused areas of your home to reduce cooling needs.
Buy energy efficient appliances.
Use paint brushes or rollers instead of spray painting to reduce the evaporation of paint.
Choose water-based paints, stains, and sealers instead of similar oil-based products. If you must use oil-based coatings, ask about the availability of low-solvent versions.
Plant trees. They filter the air and shade your home to reduce cooling needs.
Recycle. It takes less energy and pollution to recycle many articles than it does to make new ones from raw materials.
