Solar Ovens
Solar ovens come in many shapes, sizes, materials and vary in complexity. For those looking for a worst case or "just in case" plan, this seems to be the simplest method. I have found a good source for making your own solar oven.

How A Sun Oven Works
You can bake bread and cook stews and casseroles, using only the energy of the sun. The sun's rays are concentrated with one or more reflectors and collected in a black, well insulated box. Its hard to believe, but it works--with temperatures in the oven of 300-350 degrees on a hot sunny day, 175-250 degrees with partial sun and clouds. Since food is cooked slowly at relatively low temperature in a solar oven (as in a crock pot), food retains more of its flavor and vitamins and is quite simply delicious. Cooking in a solar oven retains more of the moisture in the food than in a traditional oven. Place the ingredients in the oven in the morning, enjoy your day, and return to a hot meal ready to serve. For days when the sun doesn't shine, you can always go back to your regular stove and use some of the electricity or gas you have saved.
