It is no secret that many renewable energy advocates are not in favor of large hydropower.
>[…] there exists a threat that is even more worrisome to endangered species, a threat that has the potential to cause destructive flooding and destroy ecosystems: climate change. […]
Perhaps that’s why in May of this year, the World Bank reversed its stance on large-scale hydropower. Whereas the major international development bank was once a staunch opponent of large-scale hydro, recognition that developing regions like Africa and Southeast Asia desperately need power have forced it to reconsider. The world needs energy to lift people out of poverty and building more fossil fuel-fired electricity plants will only serve to exacerbate the problems already associated with climate change. Hydropower is an answer.
Maybe it is time for the renewable energy industry to take a second look at hydropower development. The clean energy it can provide is a vast improvement over the dirty energy we get from fossil fuels. Hydropower already meets about 8 percent of U.S. electricity demand and with improved technologies that already exist the National Hydropower Association (NHA) estimates that we can double the amount of energy we get from hydropower without building any more dams.<
