Food tips
Kitchen Tip : Even though they are like magnets for spills, keep stovetop reflectors clean. They will reflect heat better and save energy. If you need new ones, buy quality. The best on the market can save as much as 1/3 of the energy used with inferior reflectors.
Oven Tips : Close the oven door gently - slamming forces out the hot air.
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.
