Keep your microwave clean and you'll be able to maximize its energy. This means less electricity used, less money spent, and less time cooking. Microwaves are between 3.5 and 4.8 times more energy efficient than traditional electric ovens. If it costs ten cents to cook one item in a microwave, it would cost forty-eight cents to cook the same item in a standard oven. If everyone in North America cooked exclusively with a microwave for a year, we'd save as much energy as the entire continent of Africa consumes in that time.  

Run full loads in your dishwasher and save energy, and don't pre-rinse your dishes before putting them in. Do both and you'll save up to 20 gallons of water per dish load, or 7,300 gallons over a year. That's as much water as the average person drinks in a lifetime. (If you must handwash, turn off the tap while you scrub.)

Fact taken from: "The Green Book", by Elizabeth Rogers and Thomas M. Kostigen 

Keep your kitchen scraps from fruits, vegetables, and coffee grounds in a composting bin or container. Try adding them to your garden or starting a compost site in the yard. You'll grow a better garden, create deeper topsoil, recycle nutrients, and save landfill space.

If, over the course of a year, everyone in the United States composted their kitchen scraps instead of sending them away with the trash, the organic waste diverted from landfills could make a three-foot-high compost pile to cover the city of San Francisco.

Walk and your commute to work is free. People who live within two miles of their office still spend $384 a year to drive back and forth. If just 20 people in every state did it, we'd save more than 64,000lbs of harmful chemicals from being released into the air. That's roughly the amount of toxic air pollutants emitted by industrial facilities within Washington, D.C. each year.
