A microwave oven uses the 120 V AC coming out of your kitchen receptacle (in the United States) and by means of a transformer and rectifier converted to 7000 V DC which is then used to energize the magnetron that creates the microwave energy.
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.
Three types of energy associated with microwaves are electrical energy used to power the microwave, electromagnetic energy emitted by the microwave to heat food, and thermal energy generated in the food as it absorbs the microwaves and heats up.
In a microwave, energy is wasted in the form of heat that escapes from the appliance and does not contribute to heating the food. Additionally, energy can be lost through inefficient conversion of electrical energy into microwave radiation, as well as losses in the components of the microwave itself.
A microwave oven uses electricity to generate electromagnetic radiation in the microwave frequency range. This radiation is absorbed by water, fats, and sugars in food, causing them to vibrate and generate heat, which cooks the food.
In a microwave oven, electrical energy is converted into microwave radiation. This radiation excites water molecules in the food, causing them to vibrate and generate heat through friction. This heat then cooks the food.
The type of energy conversion for a microwave is the transformation of electrical energy into light energy. This device works by focusing microwave light on the food inside of it.

It can do certainly. In a microwave oven there is enough energy to heat food quickly
Yes, items in a microwave oven can be said to absorb microwaves. The microwave energy causes what is called dielectric heating, and this activity takes energy from the microwave beam.

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.
