WISIONS team participated in the BREG-MES 2014 Symposium

News from WISIONS posted on April 30th, 2014

The Berkeley Rural Energy Research Group (BREG) and TU Berlin Microenergy Systems Research Group (MES) organized a symposium on "Innovating Energy Access for Remote Areas: Discovering Untapped Resources“ at UC Berkeley, California, USA on 10-12 April 2014.Read moreMinimize

The Symposium brought together practitioners and researchers to share experiences about innovative approaches for acheving equitable access to energy for the global poor and those on the margins of society. The programme combined keynote lectures, oral presentations of original research and case studies, poster presentations and panel discussions. 
Over ten sessions some of the most relevant issues about decentralized energy alternatives were discussed in depth, such as the use of mini-grids for electric power, the provision of energy for cooking, demand assessment, project planning and governance, lighting services, microfinance and the productive use of energy.

Within this framework the WISIONS team had the opportunity to share and discuss insights from our recent research in two fields:

Viogaz - Alterna Exchange: "Maximizing the biodigestion process"

News from WISIONS posted on April 23rd, 2014

Alterna is an NGO working in Guatemala. During the last years it has been active in the promotion of biodigesters in that country, for instance through the implementation of a SEPS project between 2012 and 2013. In March 2014, the Viogaz-Alterna Exchange aimed to improve Alterna's biogas program.Read moreMinimize

Joaquí­n Ví­quez is a biogas expert from the company Viogaz in Costa Rica. Joaquin visited Alterna in order to strengthen the technical capacities of Alternas' staff. The exchange comprised three main activities at various facilities like cattle/pig/chicken farms and slaughterhouses, as well as organic coffee plantations:

  • A visit and technical supervision of existing plants and potential project sites within the department of Sololá and in the town of Salcajá, Quetzaltenango
  • Conduction of the first meeting of biodigester operators in the region consisting of members of Alterna, and Viogaz, biodigestion system users and technical trading partners 
  • Intensive technical advice on characterization of effluents (both chemical and biological) for use in crop fertilization and appropriate follow-up and maintenance strategies of biodigesters

Small wind turbines – case studies in Peru

News from WISIONS posted on April 22nd, 2014

Installing a small wind turbine is the first step in providing energy access to rural communities in developing countries. One of the major problems is that particularly locally manufactured technology is susceptible to failures and therefore in need of an effective socio-technical system that guarantees operation in the long term.Read moreMinimize

Jon Leary and various colleagues who met through WindWorks activities have published an article comparing wind projects of WindAid and Soluciones Prácticas.

The systems created by two non-governmental organizations operating in the Andean region of Northern Peru were investigated and correlated to the post-installation performance of their wind turbines.
