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 ]
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]

The total installed capacity was ~2,4 GW e (position 104). [2] In July 2017, the country had a total installed capacity of ~4.3 GW e and an annual electricity production of 12.5 TWh. [3] In 2017, hydropower has the largest share with 89.5% of the installed capacity and with 93,4% of the annual electricity production.
Overall, hydroelectric power can be less expensive than electricity generated from fossil fuels or nuclear energy, and areas with abundant hydroelectric power attract industry. However, in addition to the advantages above, there are several disadvantages to dams that create large reservoirs .
The folds mimic the natural creases found in leaves, channeling more light into the cell. The researchers claimed in 2015 that the leaf-like cells generated 47 percent more electricity than those ...
