In this issue, we argue that is not rational to eliminate ﬁa prioriﬂ hydroelectric projects with reservoirs in inventory studies. The right way is to quantify both the energy benefits of these plants and their environmental damages. This type of analysis should take into account the possibility of reducing the environmental impacts through operational restrictions. It is also necessary to have computing tools able to analyze automatically a large number of configurations.
