Microwave takes less time to cook
compare microwave oven to conventional oven
You can save a lot on energy consumption by using your microwave instead of a conventional oven. Not only does a microwave cook foods faster, conserving electricity, but it does not heat up your house the way a conventional oven does, requiring your AC to work harder. And the latest models like the JES1142SJ countertop microwave are made to be energy-efficient.
No - you will get food poisoning - do not heat quiche in a microwave oven - use a conventional oven & heat thoroughly
While microwave ovens don't carry Energy Star ratings like large appliances, they are a real energy saver, using just 1/3 to 1/2 the energy of a conventional oven. At 1200 watts, this model is in the mid-range of wattage, with smaller wattage models using less energy per use.
From a resource which said that a microwave set on high is equivalent to a 375 degree conventional oven setting, and the microwave cooking time is 1/4 of that for a conventional oven; a microwave set on high for 5 minutes would be the same as a conventional oven set at 375 degrees with a cook time of 20 minutes. You might have to adjust a bit from that with trial, but it should give you a starting point to work from.
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.
We find that in the microwave oven, electromagnetic energy (microwaves) are converted in thermal (heat) energy.
Faster than a conventional oven, slower than a microwave
Into microwave electromagnetic radiation.
A microwave oven uses electrical energy (which is electromagnetic energy) from the mains, and it generates microwave energy (which is also electromagnetic energy) to heat/cook food items.
The energy waves produced in a microwave oven take the form of electromagnetic radiation at about 2,450 MHz, which is in the microwave range.
