Economy of Germany

Germany is the largest national economy in Europe, the fourth-largest by nominal GDP in the world, and fifth by GDP (PPP) in 2008. Since the age of industrialisation, the country has been a driver, innovator, and beneficiary of an ever more globalised economy. Germany is the world's second largest exporter with $1.474 trillion, €1.06 trillion exported in 2011 (Eurozone countries are included). Exports account for more than one-third of national output.
Germany is relatively poor in raw materials. Only lignite and potash salt are available in economically significant quantities. Power plants burning lignite are one of the main sources of electricity in Germany. Oil, natural gas and other resources are, for the most part, imported from other countries. Germany imports about two thirds of its energy.
The service sector contributes around 70% of the total GDP, industry 29.1%, and agriculture 0.9%. Most of the country's products are in engineering, especially in automobiles, machinery, metals, and chemical goods. Germany is the leading producer of wind turbines and solar power technology in the world. The largest annual international trade fairs and congresses are held in several German cities such as Hanover, Frankfurt, and Berlin.
Of the world's 500 largest stock market listed companies measured by revenue, the Fortune Global 500, 37 are headquartered in Germany. In 2010 the ten largest were Volkswagen, Allianz, E.ON, Daimler, Siemens, Metro, Deutsche Telekom, Munich Re, BASF, and BMW.
