Our daily life depends largely on the availability of electricity. Arising from the interaction between particles of positively and negatively charged matter, it is regarded as a secondary energy source if derived from fossil fuels (primary if derived from nuclear and renewable sources). It is produced in different kinds of power plants: thermoelectric, nuclear, hydroelectric, geothermal, solar and wind, biomass, etc.
The end goal is always the same, however: to turn a turbine connected to a generator ( dynamo or alternator), which produces electricity, and to a transformer that regulates the voltage.
