With regard to global energy demand, countries face several challenges in defining an energy policy that facilitates the process towards sustainable development. Among these challenges are the high prices of energy and its volatility; climate change and the reduction of environmental pollution; the promotion of security and energy self-sufficiency; access to resources for investment; and the efficient and rational use of energy resources. Added to this scenario is the global demand for energy which, according to international statistics recorded by the International Energy Agency (AE, acronym for US Energy Information Administration), projects a growth in global energy demand for the period 2013-2030 of 32 %, going from 12,324 Mtoe, in 2012, to 16,206 Mtoe, in 2030 (US Energy Information Administration). For the year 2012, of the primary energy source, the main fuels that supply world consumption are oil (33%), coal (30%) and natural gas (24%). The renewable primary energy source (including hydroelectricity and other sources) contributes only 8%. Graph 1 takes these data into account and allows us to observe how the world energy matrix could become by the year 2030. According to these projections, oil reduces its share from 33 to 29%. Likewise, other energy sources such as biomass are incorporated, with 11%, to reach a share of renewable primary energy sources of 17%. This is relevant, since it would reflect the result of the objective of energy policies with a focus on sustainable development, as advocated by countries seeking greater use of renewable resources.
