What is your motivation for doing this research? My aim and motivation are to demonstrate that hydropower plants have a strong impact on aquatic fauna. I am especially motivated to show that small hydropower plants cause serious impacts as well, just like large hydropower plants.
Why should we defend these wild rivers? Because those rivers have much higher value without hydropower plants. Currently, the most numerous planned hydropower plants are small sized and they are mostly planned on the streams with high ecological value. Furthermore, their very low electricity output is not efficient to increase the share of renewable electricity production!
