In the regions coloured in light blue and in middle blue, the use
of hydro-power can theoretically be extended further especially using hydroelectric
power plants of small capacity. This applies mainly to the northern mountain range
of the Jura and the peripheral part of the Alps (light blue) and also, but to
a lesser extent, to the rest of the Jura, the Pre-alps and the Mittelland (middle
blue). In the Central Alps hydro-power is maximally used.
data is based on the analysis of theoretical potential energy, as represented
on the map below. Other important aspects, such as the conservation of nature
and of landscape, have not been considered.
energy of precipitation and tributaries, and the present use of this energy
numbers represent the potential energy of precipitation, as well as the one of
the tributary, related to the altitude at which the water flows out
of the considered region (marked by a blue point). The first number means the
energy in terawatt hours per year and the second one the percentage of this energy
that is presently used for the production of electricity.
theoretical potential energy all over Switzerland is about 140 TWh per year,
corresponding to an average power of 16 GW. – However, it should be noted
that it is not possible or desirable to extract 100% of the potential energy from
The theoretical potential energy and its use have been
determined with the help of the "Hydrological Atlas of Switzerland" and the "Statistik
der Wasserkraftanlagen der Schweiz", respectively.
