melting glaciers, new lakes - the new blue pearls of sustainable hydro power?

-- a note from kt75

A recent study provides more information about the melting of glaciers, in this case of the Swiss Alps [1]-[3]. Accordingly up to several hundred new lakes will be created in the Alps. This melt down of large volumes of (fresh) water is also be seen as potential resource to be used as 'sustainable' hydro power [4]. The question remains again what is sustainable e.g. [5], [6]? Are this the new 'blue pearls' [7]?
