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.
Erected in the dead of night on August 13, 1961, the Berlin Wall (known as Berliner Mauer in German) was a physical division between West Berlin and East Germany in order to keep East Germans from feeling to the West. When the Berlin Wall fell on November 9, 1989, its destruction was nearly as instantaneous as its creation. For 28 years, the Berlin Wall had been a symbol of the Cold War and thus when it fell it was celebrated around the world.
