• Replace conventional light bulbs with energy-efficient compact fluorescent bulbs (CO2 savings for replacing six incandescent bulbs: 566 pounds a year)
• Install low-flow shower heads. (CO2 savings: 370 pounds a year)
• Use toaster ovens and/or microwaves to reheat small portions. They use much less energy than conventional ovens.
• Don't Let The Water Run while shaving or brushing your teeth. Fix toilet and faucet leaks and take shorter showers. Municipal water systems use energy to purify and distribute water.
• Turn Off unneeded lights inside and outside. Turn off lights when you're not in the room to use them. Use a motion light outside that turns on when approached and turns off when motion is undetected.
• Unplug your cellphone, MP3 player and other personal electronics as soon as they are finished charging. (CO2 savings: 200 pounds per year)
• Run your dishwasher only with a full load. (CO2 savings: 100 pounds a year)
• Wash clothes in cold water, wash and dry when you have enough for full loads and make sure to clean the dryer lint filter after every load. (CO2 savings: 500 pounds a year)
• Lower your water-heater temperature to 120 degrees, and insulate your water talk. (CO2 savings: 500 pounds a year)
• Lower your furnace thermostat in the winter by 2 degrees. (CO2 savings: 353 pounds a year)
• Clean or replace furnace air filters every two months during the heating season, and have your furnace inspected and tuned every two to three years.
• Recycle paper, printer cartridges, and other goods. Use two-sided printing and copying to save paper.
• Recycle your paper, cardboard, beverage containers, glass and metal, and compost food and yard wastes. (CO2 savings: 850 pounds a year)
• Choose plastic bags at the grocery checkout line because they take less energy to produce and are recyclable, but the better choice is to bring a reusable bag, for example a canvas bag, to carry your groceries home. (CO2 savings: 34 pounds a year)
• Keep vehicle tires properly inflated. Under-inflated tires reduce your fuel economy by as much as 3 percent. (CO2 savings: 250 pounds a year)

• Unplug your TV, DVD player, computer, and other electronics when not in use, better yet use a power strip to easily turn them off avoiding tediousness. (CO2 savings: 500 pounds a year)
• Seal Up leaky drafts, keep the damper closed on the fireplace and wood stove when not in use, and install certified energy-saving windows when replacing old windows. (CO2 savings: 2, 480 pounds a year)
• Vacuum your refrigerator and freezer condenser coils once a year, keep the door gasket and seals clean, and don't open the door longer than necessary. (CO2 savings for unplugging that extra fridge: 2,000 pounds a year)
• Use a push mower on your lawn rather than a gas powered mower. (CO2 savings: 80 pounds a year)
• Buy products with less packaging and those in containers that can be recycled. Use products made from recycled material. (CO2 savings: 230 pounds a year)
• Unload unnecessary items from your trunk and unnecessary items from work vehicles to reduce vehicle weight. If you have a removable roof rack and aren't using it, take it off. That can improve fuel economy by as much as 5 percent!
• Car Pool, ride the bus, bike, walk or telecommute. Transportation accounts for half of all greenhouse gases produced in most counties, and much of that is from people driving alone to and from work. Even better, you could help cut traffic congestion, saving time spent on the road each day. (CO2 savings from leaving your car home two days a week: 1,590 pounds a year)

• Use Green Power. Many cities and energy companies have programs that allow you to purchase, for a nominal charge per month, power from renewable energy sources such as wind, solar and biomass.
• Trade In that gas hog for a more fuel-efficient car. Each gallon of gasoline saved keeps 20 pounds of CO2 out of the atmosphere!
• Eat Locally-Grown Food. On average, fresh produce travels 1,500 miles from farm to plate. Increasingly, more of what Americans eat is shipped from overseas. Ships cause severe environmental hazards to our oceans, marine and plant life and the ozone.
• Recycle at all times. Utilize city recycling programs, buy recycled and recyclable goods.
• Plant a Tree. Well-placed trees create shade and lower cooling bills. They also use carbon dioxide during photosynthesis and can remove 50 pounds of CO2 a year! More trees equals cleaner air.
