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]
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity , almost 4,210 TWh in 2023, [ 1 ] which is more than all other renewable sources combined and also more than nuclear power . [ 2 ]
Solar potential of Nepal. Nepal gets most of its electricity from hydropower sources, but it is looking to expand the role of solar power in its energy mix. [10] The average global solar radiation in Nepal varies from 3.6 to 6.2 kWh/m 2 /day, sun shines for about 300 days a year, the number of sunshine hours amounts almost 2100 hours per year with an average of 6.8 hours of sunshine each day ...
Some hydroelectric power station failures may go beyond the immediate loss of generation capacity, including destruction of the turbine itself, reservoir breach and significant destruction of national grid infrastructure downstream. These can take years to remedy in some cases.

They are often used on small rivers or as a low-impact development on larger rivers. China is the largest producer of hydroelectricity in the world and has more than 45,000 small hydro installations. [90] Run-of-the-river hydroelectricity plants derive energy from rivers without the creation of a large reservoir. The water is typically conveyed ...

Biomass is by far the most important primary energy source in Nepal. Biomass comprises wood, agricultural residues and dung. One major problem with this is that burning these biomass substances for cooking is a common practice (87.3%) and thus exposes those living in the house to harmful air pollutants. [7]
