Use the microwave
When reheating food, or cooking small portions, use the microwave instead of the oven or range.
**How this helps**
Because it takes so much less time to cook in the microwave, you use a lot less energy — even if the microwave draws more power. According to Energy Star, cooking small portions or reheating food in the microwave can save up to 80% of the energy used if you reheated in the oven.
