To save energy when cooking with an oven, keep preheating to a minimum and make sure the oven door is fully closed so that heat does not escape. Do not use a full size oven for small cooking jobs, and do not use a pot or pan that is too large for the amount of food being cooked. Keep the oven and the stove-top clean for maximum efficiency. Gas ovens are more energy efficient than electric models, and self-cleaning models offer the best insulation.
