Shut down and unplug electronics. Make small changes to use – and pay for – less energy, like shutting down your computer when you're not using it and plugging your cell phone and other electronics into power strips so you can turn several devices off with one switch.

Use refurbished electronics. You can get refurbished electronics for a steal (they often sell for less than 50 percent of the retail price!), and before they're resold to the public, they go through an intense defect-testing process and the warranties usually remain intact.

Wash your clothes in cold water. By using cold water instead of warm, the average household can avoid emitting 1,281 pounds of carbon dioxide annually and save on energy bills

Fill your bottle with filtered tap water. Choose the greener solution by using a reusable bottle and filling it with filtered tap water, the water is just as fresh and good as if you purchased it.   

Move Your Thermostat down Two Degrees. Almost half of the energy we use in our homes goes to heating and cooling. You could save about 2,000 pounds of carbon dioxide a year with this simple adjustment.

Buy Fresh Foods Instead of Frozen, next time you are at the store. Frozen food uses 10 times more energy to produce.

Turn off the tap
Turn off the tap when brushing your teeth.

Use a Cloth Bag
Paper or plastic? Neither! Take a cloth bag with you to the grocery store. Keep them in your car and you will always have them with you, it takes very little time to form this habit.

Change your light bulbs
If everyone in your city replaced one light bulb with a compact fluorescent bulb, it would reduce greenhouse gas emissions by the equivalent of more than 20,000 cars. If every home in the country did the same, it would be like ditching 800,000 cars and would save enough energy to light more than 2.5 million homes for a year, according to Energy Star, a joint program between the EPA and the U.S. Department of Energy.
