Is it true that microwave ovens are energy-efficient?

A key advantage with microwave ovens is their energy-efficiency. The microwave energy is attracted to the moisture in the food molecules, causing them to agitate at a very fast rate, thus heating up the food. This means the microwave energy is concentrated on the food, whereas conventional equipment also has to heat up the oven cavity. Similarly, in microwaves, the power is used only during the cooking time it's never left running with no food in.

Because microwaves cook the food much quicker than conventional ovens, the overall energy consumption can be cut by up to a third. Also, less heat is emitted into the kitchen when using a microwave, so it can cut kitchen ventilation costs too.

All these factors add up to significant energy savings with a microwave oven.
