Hydroelectric energy is a renewable energy source, but it certainly is not green energy. Particularly in the tropics, the creation of of dams floods huge tracts of rainforest and releases massive amounts of methane emissions as the organic matter decomposes, thus resulting in significant atmospheric consequences. As tropical rainforests are a huge carbon sink (meaning that they store and sequester massive amounts of carbon dioxide, which would otherwise be present in the atmosphere), the loss of these critically important habitats has serious detrimental effects on global warming.

To further understand this science and the negative effects of hydroelectric power, please take a look at the following resources we have compiled:
