All of the methods mentioned above are the energy sources for electricity, but the electricity itself is generated by huge generators. The turbines of these generators are powered by:
The potential energy stored in water (hydroelectric/dams)
The chemical energy released from the carbon bonds when coal is burned
The energy released from nuclear reactions heats up water, and the steam passes through the turbines
The kinetic energy in wind is used to turn turbines in wind energy
Solar power is harnessed through a reaction in semiconducting materials (excitation of electrons from the sun's photons), which delivers a voltage directly without a turbine
