When using your oven to cook dinner, use a few simple tips to make your energy usage as efficient as possible. First, make sure your cookware is flat-bottomed; warped cookware can have reduced surface space and use up to 50 percent more energy to heat up than flat-bottomed pans. Also, copper-bottomed pans heat up faster than others, which can help save energy. If you bake in a glass or ceramic dish, you can actually set your oven 25 degrees cooler than the recipe suggests, since these dishes are better at conducting heat.
