How electricity generate?

Methods of electricity generation

There are seven basic methods to convert other forms of energy directly into electrical energy:

Static electricity through physical separation and charge transport (examples: triboelectric effect and lightning)

Electromagnetic induction, in which an electrical generator, dynamo or alternator converts kinetic energy (kinetic energy) into electricity. This is the most common form of electricity generation and is based on Faraday’s law. It can be experimented by simply rotating a magnet in closed loops of a conductive material (e.g. copper wire).

Electrochemistry, the direct conversion of chemical energy into electricity, like in a battery, a fuel cell or a nerve impulse

Photovoltaic effect, the conversion of light into electrical energy, like in solar cells

Thermoelectric effect, the direct conversion of temperature differences into electricity, such as with thermocouples, thermopiles and thermionic converters.

Piezoelectric effect due to mechanical stress on electrically anisotropic molecules or crystals.

Department of Lawrence Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have developed a piezoelectric generator sufficient to power a thin film of M13 bacteriophage liquid crystal display.

Nuclear transformation, generation and acceleration of charged particles (examples: beta-voltaic or alpha particle emission)
