World Energy System

according to Cuban news agency: Arrast?a, who is also a member of the Group of Renewable Energy of the Center for Information Management and Energy Development (CUBAENERGIA), stated that the order established by rich countries, is based on unjust, exclusive, consumerist, and speculative relations.As a consequence of this policy, the expert noted the current international market price for a barrel of oil of nearly US $140 and the high level of environmental contamination, produced mainly due to the use of fossil fuels.The Cuban specialist stressed that this pollution is the effect of age old patterns of consumption, in which oil and coal prevail (32 and 26 per cent, respectively), followed by natural gas (19), and traditional biomass (10). Nuclear power stations only contribute 5 percent of the world’s energy, hydraulic power from the exploitation of large and small waterfalls, 6 percent, and the so- called renewable energies -like solar, photovoltaic, thermal, wind, and tidal power reprsent barely 2 percent. Mario Arrast?a is a member of the Board of Directors of the Cuban Society for the Promotion of Renewable Energy Sources and Respect to the Environment (CUBASOLAR) in Havana, and a collaborator with the magazines Energ?a and Tu. He was also one of the speakers of the Round Table entitled S.O.S. Toa, recently held in the far eastern city of Baracoa, in which participants advocated for the conservation of that basin containing 70 rivers and sterns run, and that, along with the Duaba, comprise the country’s largest hydro-energy potential.
