BERLIN, March 07. /ITAR-TASS/. Economic sanctions against Russia would cause serious damage to Germany's switch to alternative energy sources, the head of the German Economic Research Institute, Hans-Werner Sinn, said in an interview published in Germany's Passauer Neue Presse on Friday.

Germany cannot afford such a policy of sanctions, as it considerably depends on Russian gas supply in the process of switching to alternative energy sources, the economist notes. According to him, EU sanctions will only harm the European countries.

Any attempt to bring such countries as Ukraine out of Russia's influence and link with the West is naive, he believes.

Russia, along with Norway, is an important supplier of gas to Germany, the publication notes.
