					Cooking with a solar oven is probably the greenest method of preparing your food.

A solar oven is a device that harnesses sunlight to create heat energy. It doesn't use
any fuel, and it doesn't cost a thing to operate it. It can help slow down the
deforestation and desertification caused by harvesting natural resources which are
used in conventional fuel production. In theory, no more trees would be cut for use in
making charcoal, if everyone switched to using solar ovens. And while the use of a
solar oven is not necessarily feasible under all circumstances, a better understanding
of their use can open up many doors and new possibilities.

There are many solar oven designs, but each of them uses the same basic principles.
They concentrate sunlight, using mirrors or other types of reflective metal, into their
designated cooking areas. The more concentrated the light, the more potent the
concentration will be.

Some solar ovens convert the light they gather into heat. You might notice that ovens
and pans generally have something black inside. This is based on the fact that the
color black absorbs more light than any other color, and turns it into heat. The more
efficient the pan or oven, the faster the cooking time will be.

Some solar ovens work by trapping heat inside them. They isolate the air within the
pan, separating it out from the outside air. This can be done with the use of a clear
solid, such as a glass cover or even a plastic bag. The barrier can thus allow light to
enter, but once the light is turned into heat, it traps the heat inside the cooker. This
type of solar oven makes it possible to reach stable cooking temperatures, even during
windy days outdoors.

The most efficient solar ovens utilize the three principles mentioned above, in order to
effectively achieve the proper temperatures for cooking with good results and in the
shortest time possible. This is especially true when the cooker will be used in a place
that which has undesirable conditions.

Solar ovens are one of the most easily-accessible devices which use alternative energy.
A solar oven can even be built out of everyday materials. There are also cheap
versions available on the market. What's best about them is that you can use them to
prepare just about anything which can be made with a standard stove or oven. You can
bake bread, steam vegetables, and even roast meat in them.

Further, solar ovens are usually placed outside the home; therefore they don't take up
any space in your kitchen.

There are also some disadvantages to using solar ovens. They generally can't be used
on cloudy and rainy days. They are most efficient during the hottest time of the day, in
the afternoon, when most people have already finished eating. But in this case, the
oven can at least be used to keep food warm until evening.
