History: Old Germany

With its central position in Europe, Germany is a transport hub. This is reflected in its dense and modern transport networks. The motorway (Autobahn) network ranks as the third largest worldwide in length. Germany has established a polycentric network of high-speed trains. The InterCityExpress or ICE network of the Deutsche Bahn serves major German cities as well as destinations in neighbouring countries. The largest German airports are Frankfurt Airport and Munich Airport, both hubs of Lufthansa, while Air Berlin has hubs at Berlin Tegel and Düsseldorf. Other major airports include Berlin Schönefeld, Hamburg, Cologne/Bonn and Leipzig/Halle. Both airports in Berlin will be consolidated at a site adjacent to Berlin Schönefeld, which will become Berlin Brandenburg Airport in 2012.
As of 2008, Germany was the world's sixth largest consumer of energy, and 60% of its primary energy was imported. Government policy promotes energy conservation and renewable energy. Energy efficiency has been improving since the early 1970s; the government aims to meet the country's electricity demands using only renewable sources by 2050. In 2010, energy sources were: oil (33.7%); coal, including lignite (22.9%); natural gas (21.8%); nuclear (10.8%); hydro-electric and wind power (1.5%); and other renewable sources (7.9%). In 2000, the government and the nuclear power industry agreed to phase out all nuclear power plants by 2021. Germany is committed to the Kyoto protocol and several other treaties promoting biodiversity, low emission standards, recycling, and the use of renewable energy, and supports sustainable development at a global level. The German government has initiated wide-ranging emission reduction activities and the country's overall emissions are falling. Nevertheless the country's greenhouse gas emissions were the highest in the EU as of 2007.
• Science and technology
Germany's achievements in sciences have been significant, and research and development efforts form an integral part of the economy. The Nobel Prize has been awarded to 103 German laureates. For most of the 20th century, German laureates had more awards than those of any other nation, especially in the sciences (physics, chemistry, and physiology or medicine).
