How can I save money with reheating last nights dinner? By using your microwave over your over you can save energy. As you know a microwave works with very high-frequency radio waves. Unlike an oven that needs to heat up to 350 Deg before it’s ready to be used. Just the energy used to pre-heat the oven is a big waster of power. Than after your food is warmed up the oven turns into a big radiator. Now your kitchen is hot and your air conditioner kicks on, then the refrigerator needs to work harder to keep cool.
So know you have 1 heater making 2 cooling devices work harder to get back to the temperature before you even sit down to eat. The microwave only heats the food and not the room around it. If you’re cooking a full meal you will need your oven but for heating up a single portion use the microwave. Even your toaster oven is uses more power than the microwave. Not to mention the heating the room air temperature like the oven did.
