Hydroelectricity is the biggest hydropower application. Hydroelectricity generates about 15% of global electricity and provides at least 50% of the total electricity supply for more than 35 countries. [17] In 2021, global installed hydropower electrical capacity reached almost 1400 GW, the highest among all renewable energy technologies. [18]
Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. This height difference is called the head.
India also imports surplus hydroelectric power from Bhutan. Small hydropower, defined to be generated at facilities with nameplate capacities up to 25 MW, comes under the ambit of the Ministry of New and Renewable energy (MNRE); whilst large hydro, defined as above 25 MW, comes under the ambit of the Ministry of Power.

The Shilongba Hydropower Station is the first hydroelectric power plant in China. [31] It was built in Yunnan province in 1912, with a capacity of 240 kW. Due to the subsequent period of political and social instability, little additional progress was made in power infrastructure in the country at that time.
