Green Tips
Run full dishwasher loads.
You'll save up to 20 gallons of water per load, or 7,300 gallons a year. That's as much water as the average person drinks in a lifetime. You can save even more money by running your dishwasher during off-peak hours, usually from 9 p.m. to 7 a.m. Many utility companies offer off-peak energy rates. And don't pre-rinse if your dishwasher can handle it.

Don't preheat.
Don't bother if you are broiling, roasting or baking a dish that will cook for an hour or more. Don't preheat for more than 10 minutes for breads and cakes. And when roasting meats or baking casseroles, turn off the oven 10 minutes to 15 minutes before cooking time runs out; food will continue to cook without using the extra electricity. $ Factor: By reducing the time your oven is on by one hour per year, you'll save an average of 2 kWh of energy. If 30 percent of U.S. households did this, 60 million kWh of energy could be saved.

Turn down the thermostat. 
Lowering it by just one degree can reduce heating energy costs by about four percent. Fact: For each degree that you raise the thermostat on an air-conditioning unit, energy consumption is reduced by 3 percent. Changing from 20 degrees to 25 degrees reduces energy consumption by 15 percent and over a year on average saves 1,000 kilos of CO2.
