The abundance of oil

During the XX th century, the rapid development of chemistry (the 1930s), and the exponential growth of the automotive market (after the Second World War ), are caught in the oil capital importance in the global economic system. The oil offers certain advantages over its direct competitors ( fuelwood , charcoal , city gas ): a high energy density , transportation, storage and easy use, and plenty that makes it possible to have low cost. This abundance accompanies economic development 30 years after the war (the " thirty glorious years "). During this period, the issues of depletion of reserves and environmental issues are completely incidental or non-existent, unlike those of the energy dependence , which leads the industrialized countries to develop alternative pathways (in fact, only nuclear power is actually developed for strategic purposes - military, etc.).
