, Source of Power ‘Power Generation’

Electricity Generation:
Power is most often generated at a power station by
electromechanical generators, primarily driven by heat engines
fuelled by chemical combustion or nuclear fission but also by other
means such as the kinetic energy of flowing water and wind

Methods of generating electricity:
 Reciprocating engines (Diesel, Gas ...)
 Turbines (Wind or Falling water)
 Photovoltaic / Solar panels (Sunlight)
 Wind and other generation methods
