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).
A 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.
A microwave uses electricity for its main energy source. then transmits into waves of electricity with high frequency to produce heat.
A microwave oven uses microwaves. This is a kind of electromagnetic wave. The energy source for the microwave oven is AC (alternating current, electricity), available in many houses.
Electricity drives it, and microwave radiation is produced. This is a form of electromagnetic radiation with a wavelength intermediate between infra red (heat) and radio waves.

Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of 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...

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.
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.
Both microwave radio transmitters and microwave ovens generate and pour out radiant energy.
Yes, microwave uses heat energy. It helps in cooking.
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.
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.
because It moves
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?
Microwave takes less time to cook
Carbohydrates
Microwaves use radiant energy, so they give off radiant energy.
why do you think coal is the most energy source we are going to use in the future
light energy
Photoautotrophs use light as the energy source for producing proteins, lipids and other organic substances. Examples of photoautotrophs are plants.
