Food tips
Oven Tips : Cook with the oven door closed. A partially open door wastes energy, costs you money, and warms you instead of the food.
Oven Tips : If you don't have one, consider buying a self-cleaning oven. They use less energy for normal cooking because of higher insulation levels. They also save on your rubber glove and cleanser purchases! However, if you use the self-cleaning feature more than once a month, you'll end up using more energy than you saved. When you clean the oven, do it right after cooking to take advantage of residual heat.
