• Power generation: electricity is created in plants capable of obtaining electricity from primary energies. The so-called renewable primary energies are wind, solar radiation, tides and non-renewables are coal, natural gas and oil. Companies build power generation facilities and own (in whole or in part) so-called power stations and infrastructure. They sell the energy generated to the companies that market them (suppliers).   

Sorry for my undeducated answer - but from what I understand we (humans) derive all our power - except batteries and burning coal or natural gas but even those two would have to be powering a generator -  from spinning a turbine to generate a static charge by rotating a loop of copper wire around a magnet and then ifs converted  into current.
