that in 2006 primary sources of energy consisted of petroleum 36.8%, coal 26.6%, natural gas 22.9%, amounting to an 86% share for fossil fuels in primary energy production in the world while non-fossil sources such as hydroelectric 6.3%, nuclear 6.0%, and (geothermal, solar, tide, wind ) accounted for a meager 0.9 percent. Fossil fuels are non-renewable resources because they take millions of years to form, and reserves are being depleted much faster than new ones are being formed.

international organisations. In order to make sense and to take constructive actions, humans create theories and frameworks for analysing facts and the relationships between them. In the field of social science, as opposed to mathematics and physics, it is very difficult to create a framework that would encompass and explain all aspects of a problem or a fact. Such framework would have to be overly simplistic and by trying to explain everything would probably explain nothing. Therefore, there

years he worked at the Los Alamos Scientific Laboratory. He became Professor of Theoretical Physics at Cornell University, where he worked with Hans Bethe. He all but rebuilt the theory of quantum electrodynamics and it was for this work that he shared the Nobel Prize in 1965. His simplified rules of calculation became standard tools of theoretical analysis in both quantum electrodynamics and high-energy physics. Feynman was a visiting professor at the California Institute of Technology in 1950, where
