[34] [page needed] At a dam in Brazil, where the flooded basin is wide and the biomass volume is high the methane produced results in a pollution potential 3.5 times more than an oil-fired power plant would be. [35] A theoretical study has indicated that globally hydroelectric reservoirs may emit 104 million metric tonnes of methane gas ...
The major advantage of conventional hydroelectric dams with reservoirs is their ability to store potential power for later electrical production. The combination of a natural supply of energy and production on demand has made hydro power the largest source of renewable energy by far.
Hydropower, biomass, geothermal and ocean power may generally be low-carbon, but poor design or other factors could result in higher emissions from individual power stations. For all technologies, advances in efficiency, and therefore reductions in CO 2 e since the time of publication, have not been included.
Instead, the dams work as a natural fire break and reservoir capable of storing water for years that gets released into land slowly over time to create a more fire- and drought-resistant landscape.

Guri Dam, a hydroelectric dam in Venezuela. Hydroelectric plants convert the energy of moving water into electricity. In 2020, hydropower supplied 17% of the world's electricity, down from a high of nearly 20% in the mid-to-late 20th century. [80] [81] In conventional hydropower, a reservoir is created behind a dam.
Solar and wind produce cleaner energy than dam-generated hydroelectricity, and advances in irrigation allow us to grow more food with less water. For all these reasons, a wave of dam removals is ...
