Deutsche Bank sees substantial room for improvement over the longer term in cost per watt terms â from $0.50/w to $0.20/w â as solar gains mainstream acceptance, is recognized as a cost competitive source of electricity, and companies develop new/improved methods to interact with customers.nverter prices typically decline 10-15 per cent per year, Deutsche Bank says, and it expects this trend to continue into the future. Large solar installers are already achieving $0.25/w or lower on large supply deals, and additional savings will be found over the next several years.
Construction of the Berlin Wall. The Berlin Wall was erected on August 13, 1961. Early on that Sunday morning the GDR began, under Secretary General Erich Honecker, to block off East Berlin and the GDR from West Berlin by means of barbed wire and antitank obstacles.
In response, East Germany built a barrier to close off East Germans' access to West Berlin (and hence West Germany). This barrier, the Berlin Wall, was first erected on the night of August 12â13, 1961, as the result of a decree passed on August 12 by the East German Volkskammer (âPeoples' Chamberâ).n November 9 the East German government opened the country's borders with West Germany (including West Berlin), and openings were made in the Berlin Wall through which East Germans could travel freely to the West. The wall henceforth ceased to function as a political barrier between East and West Germany.
