In the Kitchen, your share of the work.

1. Don’t waste energy preheating your oven, most ovens don’t need it. For pastries and cakes, preheating 10 minutes is plenty. You can also turn your oven off 15 minutes early for major items like roasts and casseroles, the heat left in the oven will finish the job.
   
2. Turn down the heat after water boils. Lightly boiling water is the same temperature as a roaring boil.
3. Cooking frozen foods uses more energy, thaw them out first.
