Purchase a water-filtration system if you are concerned about your drinking water, instead of relying on bottled water.
Use a toaster oven for small jobs. It will use 33%-50% less energy as a full-size oven.
Use reusable containers to store food in your refrigerator instead of always wrapping food in aluminum foil or plastic wrap.
Reuse cardboard boxes for shipping or moving. Large stores discard hundreds of clean, sturdy boxes in all sizes every day.
Get your news online and cancel newspaper subscriptions.
Commute to work by bicycle if possible.
Reuse scrap paper before recycling it. Turn scrap paper into a handy scratch pad for making lists, scribbling notes, and doodling.
Buy rechargeable batteries and a battery charger. Most rechargeable batteries can be recharged up to 1,000 times.

Always cover pots when cooking. It speeds up cooking & uses less energy.
Donate empty egg cartons to a local egg producer. Sometimes you can make the donation through the store that sold you the eggs.

Drive slower. For every mile per hour you drive under 65 mph, you improve your car's fuel efficiency by about 2%.
Keep you vehicle tuned up. A well-tuned engine will conserve gas and reduce toxic emissions produced by your engine.
Use car roof racks on an as-needed basis only. Their use increases wind resistance, which increases fuel consumption.
If your errands cover a three-mile radius, leave the car at home and ride your bicycle.
Buy gift wrap made from recycled paper.
If you live in a cold climate, paint your house a dark color. If you live in a warm climate, paint your house a light color.
Clean or replace the filter in your air conditioner once a month. Otherwise the fan has to work harder and this consumes more electricity.
Make sure the kitchen faucet is in the "cold" position when turning it on for brief periods. You'll waste significant energy turning on the hot water even before hot water starts to flow.
Clean your clothes dryer’s lint trap after every load to keep the air circulating efficiently.
Keep your car tuned-up. It’s the easiest way to make your car more fuel efficient. A well-tuned car uses less gasoline than a poorly-tuned car. That means fewer toxic emissions.
Keep your car’s fuel filter clean. Clogged filters use more gas.
If there’s no insulation in your home, you’re costing yourself and the environment a fortune. If you do have insulation, check to see if you have enough. Even add-on insulation pays for itself in a few years.

Important Tips*(*all tips are taken from the following two books:)
Save old towels and T-shirts for cleaning. Cut them into squares and they become useful rags.
Keep rags in the kitchen to wipe up spills instead of using paper towels every time. Then wash the rags and reuse them.
Wash clothes in warm and cold water and you will use 80-85% less energy compared to using hot water.
Line dry your clothes in warm months. If you've got two trees in your yard, you can string up a clothesline in minutes.
Install dimmer switches where dimmed lighting makes sense, like the dining room and hallways. Dimming a light saves energy.
Switch to fluorescent bulbs in areas where extended lighting is required. Although the initial price is higher than for incandescent bulbs, fluorescent lights produce four times as much light per watt, last up to ten times as long and therefore cost one-third as much to operate.
Soak labels off glass jars and reuse the jars around the house for food storage or to organize loose items.
Fill a bowl with cold water and wash fruit and vegetables this way, instead of letting water from a faucet run over them.
Don’t run the washing machine if it’s not full. You’ll save a lot of water if you wait until you’ve got a full load of wash.
Store a pitcher or bottle with water in the refrigerator instead of running the kitchen faucet until the water runs cold enough for you to drink.
Never throw a cell phone into the trash. Make sure it gets reused or recycled. Cell phones have a toxic waste stream including lead, mercury, and cadmium.
Compost scraps from your kitchen to produce rich humus for your garden.
Don't use a hose to clear dirt and leaves out of the garage or off sidewalks, driveways and patios. Use a broom to conserve water.
Check the weather forecast before automatically watering your lawn. There could be rain in the forecast.
Never water with a sprinkler on a very windy day. Wind will carry away much of the water before it hits the ground.
Plant native grasses, plants, trees and shrubs in your yard. Since they are adapted to local insect species and weather, they won't require extra watering or pesticides. Your local nursery can help you select species.
Water your yard or garden in the early morning or evening when it is cooler. This will discourage excessive evaporation.
Use the reply envelopes you receive in unsolicited mailings for your own mailing needs. It is quite acceptable for casual mailings. When ready to use, ink over any preprinted bar codes, then affix an address label over the pre-printed addresses.
Unplug appliance to save energy while you are away. Many small and large appliances continue to draw electricity even when turned off.
Turn off the water while brushing your teeth or shaving. Running the water continuously for just two minutes can waste three gallons of water! Fill a cup with water when brushing your teeth and fill the sink bowl to rinse your razor instead of running the water.
Try joint ownership with family, friends, or neighbors of large or expensive things that receive only periodic use, such as lawn mower, chain saw, snowblower, power tools, car ramps, etc.
Buy a thermos mug or ceramic mug and keep one at work and/or in the car. Every time you visit a coffee shop, use that mug instead of the polystyrene cups they provide.
When buying packaged products, all other things being equal, buy the brand that uses the least amount of packaging.
Turn your ignition off when you will be stopped or parked for more than thirty seconds. Idling for more than 30 seconds burns more gas than it takes to restart the engine and thus produces more toxic emissions.
Buy products of quality that will last a long time. Avoid buying products that are made cheaply, to be used once and then disposed.
What we call “styrofoam” is actually polystyrene foam. There is no such thing as “safe” polystyrene foam. Don’t use it. Avoid foam packaging. Buy eggs in cardboard, not styrofoam, cartons. If you eat at fast food restaurants, ask for paper, not styrofoam, cups and plates.
Because CFCs (chlorofluorocarbons) destroy the earth’s ozone layer, don’t buy aerosol cans containing CFCs. Better yet: don’t use aerosols at all.
Bring your own bag when you go to the grocery store. Just say no to paper and plastic.
When shopping, buy fruits and vegetables loose, and not in plastic bags.
