The Video site says this about the video: Published on Nov 6, 2012 European rivers are negatively impacted by thousands of hydropower installations and barrages, with many more to come if the power industry has it their way. Energy produced by hydropower installations is per definition “renewable” energy – but “green” or “clean” it is certainly not. This film is produced to inform about the hydropowers devastating impact on our rivers and the life in them.

COMMENT: This is an excellent video indeed, visuals showing the devastating impact that hydropower projects can do to the river, the fish and the biodiversity across the river and also in turn on the people (though it does not have as much about the social impacts as one would like and as would be applicable in a country like India). It also shows the adverse impacts of the peaking mode of generation and also shows that even in a temperate country like Germany,the hydropower reservoirs can be a source of methane, a gas having 21 times more impact on global warming compared to carbon dioxide. It mentions how fish ladders and fish passages are hardly effective.
HOWEVER, it seems to privilege big hydro project as against small hydro and even micro hydro projects (the commentary mentions projects as small as 20 Kilo watts) over large hydro, seeming to say that the impact of smaller projects on fish (impact hydropower projects on fish seems to be focal point of the video, not the river as the title says) compared to large hydro and actually advocates moratorium on small hydro and also decommissioning of small hydro (as Denmark seems to have done, as shown in the video).
That message may not be as much relevant for a country like India where such micro projects are the only ones that can provide electricity to the communities that do not have them and when such micro projects are the only ones that can be taken up in a participatory way for the benefit of the local communities and where impacts are easier to understand and accept.
Otherwise this is an educative video for all those concerned about the impact of hydropower projects on the river and its biodiversity, particularly fish. This is particularly relevant for India in the context of the social angle and hence is particularly important with reference to larger hydropower projects.
