Is an Ewave convection oven more energy efficient than other convection ovens?

An Ewave convection oven is not more energy efficient than other convection ovens. In their article, "Better Cooking Through Convection," Fine Cooking reports that a convection oven will cook food about 25% faster than a conventional oven. Ewave's own user manual reports a 25-30% faster cooking time.

The efficiency of a convection oven depends on how quickly food is prepared and varies with each type of food. The Ewave convection oven fits into a relatively new category of countertop convection ovens, which satisfy a need for healthy eating without taking up the space of a microwave oven or the expense of a full-size convection oven or range.
