i guess its time to throw my 2 cents in, being as i am a student of environmental studies and all
the theory behind these "run of the river" projects is decent. the idea to take a small portion of water from a river, generate electricity with it, and then return it back to the river. sounds (and is) a great idea, if done in such a way as to not harm the river. now the problem is, us humans are a greedy lot. we want the most bang for our buck, and dont (well most of us anyway) give a damn what it takes or does to our surrounding, so long as we make some profit.
now in my studies i have read some of these 'reports' and 'ecological assessments' that have been done on some of these rivers before dams and other developments have taken place. some of them were well done (when it seemed for the most part, they were done by either local-ish departments or by groups who actually care about the environment). whereas most of the time, the company just wants to develope asap, and the ecological impact surveys are glossed over. and in the end, no one really knows the damage being done, and the companies could care less, for they are making big bucks.
and the problem is, like with that valley shown in the video (which i suddenly cannot remember the name of), once the damage is done. it is done "forever" (in a human point of view). and not only is the river altered, but everything depending on the river and its fish, from green rock slimes up to bears and even the forests benefit from strong fish returns (read up about the impact of salmon on trees and their growth rates).
anyways... what gets me the most is, how the community said
NO to the project but the government basically said,
too bad so sad, we're gona do it anywhere. its for the best interest of everyone (aka, their own pockets) lol, so much for democracy...
anyways rant over... >.>
