Power generation is the process of generating electrical energy from the available sources of primary energy. The power generating stations mainly based on sources on the primary energy such as renewable energy and non-renewable energy power generations. On the development of technology, many primary sources are into action for the production of power.
List of 5 Largest Power Generating Stations In The World
1. Three Gorges Dam
The Three Gorges Dam ranks the 1st on the power generation, the main primary source is the hydro. The dam is constructed on the river Yangtze River located in the Yiling District, Yichang, China.
