1. Introduction
The most important factor in the fate of societies and nations is command of energy. Energy is defined as the ability or capacity to do work. Energy policy in the European Union represents one of the core policies since the beginning of the European Integration. The treaty of Paris to establish a European Coal and Steel Community (ECSC) and the European Atomic Energy Community (EURATOM or EAEC) were the first attempts to an energy cooperation within the European Community. As the size of the European Union grows (reached twenty eight member states as of March 2013), it needed more energy sources as energy plays an important role for economic development. Now the European Union is the largest importer of energy (oil and gas) in the world, and the second largest energy consumer. Therefore, member states of the EU need more secure access to energy resources. Beside the North-South and East-West energy corridors, Europe ingests the South-North corridor, connecting it with North Africa and the Middle East. In 2007 Oil and Gas Journal estimated stocks and supplies of oil at 114 billion barrel and natural gas at 13, 9 billion cubic meter. Almost one third of European imported oil comes either from the Middle East or from North-West Africa. Europe pipeline interests in the south are focused exclusively on natural gas. In 2006 Algeria delivered 16, 7% of Europe gas, and it’s considered to be the biggest third land delivers natural gas, including LNG (Liquefied Natural Gas), to Europe. Almost half of the supplies to Europe go to Spain and the rest to Italy and France. The other two important countries in the region producing Gas are Libya and Egypt, they hold together with Algeria a proven reserves of 4, 5% of the world reserves. These three lands can present a reliable long-term alternative to the Russian gas. Starting from 2020 Algeria for example can
