Hydroelectric dams were recently recognized to threaten a number of species on reservoir islands. Popular around the world, hydroelectric dams were discovered to have a reduction in animal and plant life after flooding. The dams have been said to protect species from hunting and deforestation, but research has shown a disturbing trend. After careful inspection […]

A team of researchers from the WSU (Washington State University) have discovered that dams with their water reservoirs, nowadays universally considered green energy resources, are actually contributing to the heating of the global climate. How? Read on. Methane, as it’s well-known, is 25 times more powerful than carbon dioxide when it comes to its greenhouse-causing […]

Ten years ago, a report based on measurements taken at a hydroelectric plant in Brasil said that the gas (CO2 and methane) emissions of hydroelectric power (HEP) reservoirs account for 1 to 28% of the total greenhouse gas emissions caused by man. The report said that the CO2 and the methane came from the rotting organisms contained in the HEP reservoirs.
