WISIONS of Sustainability

The main objective of WISIONS is to make clean energy a default solution for basic energy needs in developing regions, by helping local partners to identify successes and bring them to scale through regional networks, marketing and demonstration.

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.

WISIONS team participated in the 5th World Summit for Small Wind

News from WISIONS posted on April 7th, 2014

The 5th World Summit for Small Wind took place at Husum – Northern Germany – on the 20th and 21st March 2014. The summit has become a global discussion platform for the small wind sector. Manufacturers, scientists, policy makers and an interested audience discussed the new trends and concerns that the sector faces.Read moreMinimize

At this year summit 22 speakers from 14 countries presented a unique overview of policies and markets, technological innovations, certification concepts and new standards.  

In general terms the presentations and discussions highlighted the fact that recent policy shifts in many countries do not really support the small wind turbine industry. Supportive mechanisms such as net metering, feed-in-tariffs and other instruments to promote investment and the adoption of the technology have either been reduced or even totally abandoned  in many countries. However on the positive side, the presentations also demonstrated that the sector is highly creative and innovative: some of the strategies that the industry is exploring in order to maintain or broaden the global market for small wind turbines include improved and cheaper designs, better integration with electronic components, new business models and integration with solar technologies. 

In this context WISIONS shared experiences gathered during the last 3 years through its Regional Partnership ‘WindWorks', which is coordinated by GreenEmpowerment. The main lessons highlighted by WISIONS were:

  • Small Wind has competitive advantages vis-í -vis solar power only in a narrow niche in most Latin-American countries.
  • Small Wind offers advantages as an off-grid solution where there is a very strong wind resource and relatively low solar radiation during certain times of the year.
  • Secure long-term access to both technical support (i.e. know-how, skills and spare parts) and sufficient finances to fund this support are crucial for the sustainability of small wind off-grid solutions.
  • Many stakeholders in the region are interested in small wind for rural development and other niches.
  • Cooperation between WindWorks and the WindEmpowerment Network is anticipated in the future.
