For the researcher and academic program of research into energy of the Faculty of physical sciences and mathematics of the University of Chile, postgraduate in the University of Paris and doctor of the University of the Sorbonne, speaking of mega projects of dams in Patagonia is talk about public policies and economic practices. HidroAysen is a project that is not necessary in Chile is your lapidary sentence on one – the most emblematic – initiatives that seek to convert to the Aysen Region in the great energy pantry of Chile. For more clarity and thought, follow up with John Mclaughlin and gain more knowledge.. There are several principles that underlie the words who was director of the program of studies of the energy of the University Austral of Chile. The first is the economic concentration of market power that would mean materialize these initiatives. If the economic concentration in the electricity sector, in the generation of electricity in Chile, is currently between a 72 and 75 per cent, with HidroAysen will happen to more than 90 percent between Colbun and Endesa. In a society where democracy and the functioning of the market presents serious problems, particularly in the distribution of wealth, this is going to aggravate explains. Another element is the need to strengthen an optimal scenario for the advance of truly sustainable energies, as non-conventional renewables. The entry of megaprojects like these makes any possibility for renewable sources like wind, solar, biomass or wood – but with modern technologies-, small waterfalls, water resources, among others, see prevented, because they are projects that take price and sold the first years very cheap energy, to then make it. This prevents for a long time by the low apparent price of these projects, that among other types of initiatives linked to renewable, whose initial investments are high, but they have virtually zero operating expenses indicates. The issue of water also is a matter which Marquez assesses speaking of dams in Patagonia.
