They are powered by electricity of course, but the generate microwaves (an electromagnetic wave, like light - but of a higher frequency). We are surrounded by microwaves from the sun, satalites, and radiation from electrical dewvices, but microwaves concentrate the energy - heat happens where "beams" cross and excite the molecules of what they are passing through (i.e. heat).

∙ 14y agoA microwave OVEN typically gets its operating energy from your local electric utility company, by being plugged into a wall socket in the kitchen. It uses that energy to run the high-power radio transmitter that it has inside. It generates a powerful radio signal at a frequency of around 2.4 GHz, and it pours all of that electromagnetic (radio) energy into the cooking space. The intense electromagnetic radiation causes heating when the food absorbs it. A microwave RADIO gets its operating energy from either a wall socket or a set of batteries in the communications site. It also uses this energy to run its transmitter, plus a receiver. The electromagnetic energy (radio signal) that it generates is directed outside and up to a large dish antenna, usually high on a tower, for communication with another radio site anywhere from 1 mile to 50 miles away. This link is used to carry the telephone or television service that you use. The microwave radio can easily communicate 50 miles with 1 watt of radio energy. The microwave oven needs 600 to 1500 watts of radio energy to cook your food. That's why it's built in such a way that it can't run with the door open.

What items use heat energy.?
Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of energy.
Does a microwave have chemical energy?
If you are referring to the oven, the answer could be yes, as the turn table moves. However if you are referring to the electromagnetic wave known as a microwave then this is a form of electromagnetic energy...
What would happen if crude oil ran out?
The we (i.e., mankind) would have to use some other source of energy.The we (i.e., mankind) would have to use some other source of energy.The we (i.e., mankind) would have to use some other source of energy.The we (i.e., mankind) would have to use some other source of energy.
What is meant by a renewable source of energy?
Renewable source of energy means that this source is not exhaustible by its use in producing electricity or heat (steam) or mechanical energy. An example is solar energy. Using sunlight to produce electricity through special devices, called photoelectric cells, will not exhaust sunlight coming to earth. Fossil fuels like oil, gas, and coal are examples of nonrenewable sources of energy as they are exhausted by their use.
Sources of energy and their uses at home?
the energy source that you use at home is thermal energy because when you are at home, you are sitting and the you get up the next minute. thermal energy is the sum of kinetic and potential energy due to its random motion.
Does a microwave use radiant energy?
Both microwave radio transmitters and microwave ovens generate and pour out radiant energy.
Does a microwave use heat energy?
Yes, microwave uses heat energy. It helps in cooking.
What kind of energy does a microwave oven use?
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.
Is the Panasonic Energy Star approved?
No, this microwave is not energy star approved. In fact, Energy Star does not currently approve/label ANY microwave ovens. However, most microwave ovens of the same size/wattage use comparable amounts of energy, and microwave ovens use substantially less energy than conventional ovens.
Does a microwave use machanical energy?
because It moves
Is there a light inside of the microwave when it is not in use?
No, when it is not in use, the microwave would not have a light on. Why would you want the light on when you are not using it and waste energy?
Why does a microwave use less energy than a conventional oven?
Microwave takes less time to cook
What do cell use as a source of energy and for source of energy storage?
Carbohydrates
What gives out the microwave?
Microwaves use radiant energy, so they give off radiant energy.
Why do you use coal source energy?
why do you think coal is the most energy source we are going to use in the future
What source of energy do organism use when they do not use the sun's energy?
light energy
Autotrophs that utilize light as their energy source are?
Photoautotrophs use light as the energy source for producing proteins, lipids and other organic substances. Examples of photoautotrophs are plants.
