Microwaves are between 3.5 and 4.8 times more energy efficient than traditional electric ovens. Cooking and reheating with a microwave is faster and more efficient than the stovetop or oven.
Cooking with microwaves can reduce up to 70 percent of energy use for cooking. What's more, using microwaves extends the life of your oven significantly. And one more thing: Cleaning a microwave oven is a snap and saves even more of the cash you would spend on energy with a self-cleaning oven or on toxic-chemical oven cleaners
