Fuentes y empleo de energia, experiencias de electrificacion rural con microcentrales, capacitacion y mantenimiento de microcentrales, estudios de impacto de la electrificacion rural

Com o objetivo de avaliar a potencialidade das aguas de poco tubular para pequena irrigacao e tambem o desempenho de sistemas de bombeamento e distribuicao de agua por catavento ligado a um reservatorio para o consequente dimensionamento da area a ser irrigada, foi montado este trabalho de Pesquisa-Desenvolvimento nas comunidades de Lagoa do Angico e posteriormente, Canoa (Massaroca) tentando dar uma maior estabilidade aos sistemas de producoes do semi-arido nordestino. A presente proposta tenta desenvolver uma alternativa baseada sobre o aproveitamento das aguas subterraneas, mais permanente se o bombeamento foi limitado as possiblidades do lencol. E a comprovacao destas hipoteses que sera objetivo deste trabalho.

Treballs Finals del Màster d’Energies Renovables i Sostenibilitat Energètica, Facultat de Física, Universitat de Barcelona, Curs: 2020-2021, Tutors: Cristian Fàbrega, Albert Casas | Desalination of seawater has become the most recurrent way to obtain fresh water. The climate changes that have recently occurred, plus the global overpopulation, have increased the need to find out new ways to obtain drinking water. Many technologies have been used to find a solution to remove dissolved salts in seawater, however, the most relevant technology nowadays is the desalination of seawater by Reverse Osmosis (SWRO). RO is a technique to obtain fresh water by passing seawater through a membrane at high pressure, this technique has been strongly promoted, considering the inclusion of renewable energies which change the source of traditional electricity generation by fuel to this type of renewable and sustainable energy. The Carrizal desalination project (La Guajira Colombia), is a plan with a social focus that seeks to bring drinking water to the indigenous Wayúu population, using electrical energy from a network-assisted system, implementing a main wind power source and a photovoltaic power source as backup. The technical and economic feasibility of the project will be the purpose of this document, identifying the necessary feed water, the energy required for production, the design of the generation systems and the integration with the electricity grid, as well as recognizing the implementation costs of each technology and the possible environmental impact
