Se señala cada vez con mayor énfasis que, pese a que las experiencias de generación eléctrica por medio de la energía solar en el norte del país han tenido un impacto social importante, todavía no se pudo generar con ellas una alternativa económicamente viable. Se destaca también el hecho, que la legislación actual prevé que la matriz energética alcance un 8% del total generado, empleando energías renovables (ER) para 2016, y para ello es necesario contar con políticas energéticas adecuadas y un marco institucional propicio que habiliten la inversión. Al mismo tiempo se plantea entre otras razones, que la legislación es inadecuada, puesto que existen algunas leyes anticuadas que no se aplican o no se controlan, y un régimen de subsidios que en su contexto no es favorable. También hay que admitir que todavía existen barreras que impiden una adecuada utilización de la tecnología. Como contrapartida, operan en América Latina plantas FV que comercializan la energía funcionando, a priori satisfactoriamente. Se propone entonces, para una primera instancia, la instalación de un parque fotovoltaico de 20Mw para conectar a la red de alta tensión existente. ; Despite the experiences of power generation through solar energy in the north, have had a major social impact, yet no one was generated with them an economically viable alternative. This fact was also noted that the current legislation provides that the energy matrix reach 8% of the total generated using renewable energy (RE) for 2016, and it is therefore necessary to have adequate energy policies and an enabling institutional framework to enable investment. At the same time it raises among other things that the law is inadequate because there are some outdated laws that do not apply or are not controlled. There is now also a system of subsidies which by its nature is not conducive to the promotion of RE. We must also admit that there are still barriers to appropriate use of technology. Moreover and difference what happens here, in various countries of Latin America fv function properly marketed energy plants running, a priori successfully. Installing a 20MW photovoltaic solar park is then proposed for the first stage in the NOA region, to connect to the existing high voltage network. ; Fil: Cadena, Carlos Alberto.

Se analizan las políticas públicas ejecutadas en los últimos años por el gobierno nacional tendientes a mitigar la pobreza energética en zonas rurales de la provincia de Salta en el noroeste argentino. Se revisan críticamente algunas experiencias a partir de la implementación del Proyecto de Energías Renovables en Mercados Rurales (PERMER) desde sus inicios en los años ´90. El estudio dio lugar al diseño de una intervención integral que contemple múltiples aspectos que permitan tener disponibilidad de energía para emprendimientos productivos, uso sanitario y calefacción en los hogares. Se subraya el importante potencial del recurso solar como fuente de energía en la zona de estudio. ; The public policies implemented in recent years by the national government aimed at alleviating energy poverty in rural areas of the Salta province in northwestern Argentina are analyzed. Some experiences are critically reviewed from the implementation of the Renewable Energy Project in Rural Markets (PERMER) since its inception in the 90s. The study led to the design of a comprehensive intervention that includes multiple aspects that allow energy availability for productive enterprises, sanitary use, and heating in homes. The important potential of the solar resource as an energy source in the study area is underlined.

En el presente trabajo se consideran algunos factores a tener en cuenta cuando se proyecta la instalación de un generador eléctrico no-convencional. Para el caso que se expone, se trata de instalaciones de tipo solar-térmico como complemento de sistemas de generación convencional ya existentes. El equipo podría estar interconectado al Sistema Nacional, o bien a una mini red aislada. La zona de referencia se encuentra en la provincia de Salta, aunque la mayoría de las consideraciones corresponden a también a las provincias de Jujuy, (debido a que muchas de las características que se tienen en cuenta son similares, y en los hechos este límite, se trata de una mera división política) y Catamarca (en un grado de similitud ligeramente menor). En este sentido se plantean algunos escenarios posibles, en regiones diferentes en la primera provincia mencionada. Este tema, también está relacionado con el aumento sostenido de la demanda en los últimos años y que sin lugar a dudas es uno de los factores que contribuye a agravar las actuales limitaciones que padece el sistema eléctrico argentino. Hoy, y como consecuencia su envergadura, las centrales de este tipo no pueden dar respuesta a la problemática del país, pero su desarrollo futuro es promisorio. ; In the present paper are considered some factors when planning the installation of a non-conventional electric generator. In this case, a solar-thermal system complement existing conventional generation. The equipment could be interconnected to the national system, or a mini isolated network. The reference area is located in the province of Salta, although most of the considerations are also in the provinces of Jujuy, because many of the features that are taken into account are similar. In fact this limit, is merely a political divide. In a slightly lesser degree of similarity there is Catamarca. In this regard planted some possible scenarios in different regions in the first province said. This topic is also related to the sustained increase in demand in recent years and that undoubtedly is one factor that contributes to aggravating the current limitations faced by the Argentine electric system. Today, as a result its size, the plants of this kind can not give an answer to the problems of the country, but its future is promising. ; Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES)

La energía cumple un rol fundamental en el desarrollo integral de los individuos como miembros de una comunidad que aspira a la igualdad social. El acceso a la energía es un habilitador de hábitat y resulta clave, desde la perspectiva de derechos, su inclusión en el diseño de políticas públicas de hábitat. El artículo analiza el desarrollo del Programa de Mejoramiento de Barrios (hasta el componente III) que lleva adelante el Estado Argentino y el rol de la energía en la intervención. El abordaje teórico-metodológico realizado implica la construcción del fenómeno como un caso de estudio, a partir del enfoque socio-técnico. El Enfoque privilegia la triangulación de teorías y la incorporación de elementos económicos, culturales, legales y tecnológicos al análisis sociológico. Se revisa brevemente la trayectoria y la dinámica socio-técnica y se reconstruye la alianza socio-técnica incorporando, en la discusión, la perspectiva de transición sustentable para determinar el grado de funcionamiento/no funcionamiento del programa. Se retoma, por momentos, como ejemplo la experiencia del programa en la Ciudad de Salta (Argentina). Una conclusión emergente refiere a la necesidad de abrir los modelos hegemónicos de intervención y diseñar políticas sistémicas, que operan en diferentes planos, a partir de una trama compleja de alianzas socio-técnicas, que incluyan a la energía como un elemento central para alcanzar objetivos de inclusión social.

A level playing field is key for global participation in science and scholarship, particularly with regard to how scientific publications are financed and subsequently accessed. However, there are potential pitfalls of the so-called "Gold" open-access (OA) route, in which author-paid publication charges cover the costs of production and publication. Gold OA plans in which author charges are required may not solve the access problem, but rather may shift the access barrier from reader to writer. Under such plans, everyone may be free to read papers, but it may still be prohibitively expensive to publish them. In a scholarly community that is increasingly global, spread over more and more regions and countries of the world, these publication access barriers may be quite significant. In the present paper, a global suite of colleagues in academe joins this debate. The group of colleagues, a network of researchers active in scholarly publishing, spans four continents and multiple disciplines in the natural sciences, humanities, and social sciences, as well as diverse political and economic situations. We believe that this global sampling of researchers can provide the nuance and perspective necessary to grasp this complex problem. The group was assembled without an attempt to achieve global coverage through random sampling. This contribution differs from other approaches to the open-access problem in several fundamental ways. (A) It is scholar-driven, and thus can represent the 'other side of the coin' of scholarly communication. (B) It focuses on narrative report, where scholars were free to orient their responses as they saw fit, rather than being confined to binary or scalar choices. Finally, and perhaps most importantly, (C) it distinguishes among institutions and countries and situations, highlighting inequalities of access among wealthy and economically-challenged nations, and also within countries depending on the size and location of particular institutions.
