ENERGY CAN BE GENERATED ONLY AS A ALTERNATIG CURRENT.THERE IS NO WAYS OF GENERATING ENERGY AS A DC DIRECTY.IN CASE OF DC GENERATION ,AC IS GENERATED FIRST AND THEN RECTIFIED INTO DC. TO UNDERSTAND THIS CLEARLY YOU NEED TO KNOW THE WORKING OF GENERATORS. THE REASONS FOR GENERATING ENERGY AS AC IS ENERGY CANNOT BE GENERATED AS DC.
Because AC allows the power to be transmitted over distance at high voltage and then transformed down for the users.
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
Electrical (alternating current)
Alternating current, yes. But it is not quite correct to say "electrons move to the homes... " rather, it is the CURRENT that moves to the home. It is more like a wave, where the energy is transmitted from one particle to the next.
An alternating current (AC) is an electric current whose direction reverses cyclically, as opposed to direct current, whose direction remains constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy.
Each type of energy conversion should be investigated separately. The example you mention - converting radio waves to electrical energy - works as follows: The electromagnetic wave (the radio wave) arrives at an antenna as an alternating electrical and magnetic field - so this will quite naturally induce an electrical current (alternating current).
Electric current from a generating plant is a alternating current transmitted at high voltages, but usually used at low voltages.
Alternating current electrical energy.

Electrical (alternating current)
alternating current electricity, or AC current, or AC.
To generate an alternating current, a magnet must use kinetic energy. This means that the magnet must move at a certain speed and velocity in order to create a strong enough energy charge.
electric current generate so many types one of mechanical energy convert electrical energy by using generator
A Dynamo (direct current) or Alternator (alternating current).The word Generator is occasionally also used, generically.
It changes direct current (DC) to alternative (AC) energy.
Depending on the type of generator: Electricity in the form of direct current (DC) or alternating current (AC) is produced.
Usually - but not always - electricity powers our lights and appliances.
