Use caulk or weather stripping to reduce air leaks around windows and doors. Insulate your attic, water heater, hot water pipes and furnace ducts if they're not already. Change your air filters regularly if you have a forced-air furnace and opt for light bulbs that use less electricity, such as compact fluorescent bulbs.

Ditch Your Old Thermostat
If you don't have a programmable thermostat already, a new one is easy to install. Adjusting your thermostat by 10 to 15 degrees when you're not home or you're sleeping can cut your energy use by as much as 15%, according to the Energy Department. You can also save energy by adjusting your thermostat by 1 or 2 degrees when you're home, using thermal window coverings and turning off your heating and cooling systems on nice days and opening your windows instead.

Washing your clothes in cold water eliminates 90% of a typical washing machine's electricity usage, according to the Environmental Protection Agency. You can also save energy and water by only washing full loads or reducing water levels for smaller loads. When it comes to drying, opt for dryer balls to speed up your drying time, or skip the dryer altogether and hang your clothes to dry.

Use Native Plants in Your Landscaping
The Environmental Protection Agency reports that outside water accounts for as much as 70% of all water use in some parts of the country, and as much as half of that water may be wasted due to evaporation, wind or runoff. Reduce your water usage and waste by choosing native plants that are well-suited to local growing conditions.

Buy Local, Organic and In-Season Foods
The products in your local supermarket may have originated from countries all over the globe, and all those miles on trucks, trains and planes can quickly add up to a big impact on the environment. Pay attention to the labels on the foods you buy and opt for ones that are locally or domestically produced. Or better yet, grow your own food.

Drink Tap Water
Packaging and transporting bottled water requires considerably more energy than tap water, which is delivered right to your faucet. Additionally, there's no guarantee that bottled water is any safer or better than tap water. A four-year review of the bottled water industry by the Natural Resources Defense Council found that about 25% of bottled water is actually tap water in a bottle, sometimes without further treatment. If you're concerned about contaminants in your water, use a filtration pitcher or a filter that connects to your faucet, refrigerator or plumbing.

Airplanes produce the same kind of carbon emissions as cars and trucks, so you can reduce your carbon footprint by limiting your air time. Opt for a staycation rather than flying to a far-flung destination and limit your business trips by considering video conferencing instead. And when you do fly, choose a direct flight where possible.
