Electricity
  (production)
Switzerland, a country with a lot of mountains, has many possibilities to build reservoirs for hydroelectrical power plant. 60% of the electrical current production in Switzerland is still based on water.

 

 
Electrical current Production in Switzerland since the beginning of 1999:
MWh (MJ=Megawatt hours) are based on water, MWh on nuclear power, and MWh on thermic power plants.

 
Total electrical current production since 1.1.99 MWh. But reservoir pumps use MWh of that.

So the net current production since the beginning of 1999 is: MWh.
The numbers are estimations from 1997 data. They base on the "Zahlenspiegel der Schweiz 1999" edited by the "Gesellschaft zur Förderung der schweizerischen Wirtschaft (wf)".
