Access to sustainable and affordable energy services is a crucial factor in reducing poverty in developing countries. In particular, small-scale and community-based renewable energy projects are recognized as important forms of development assistance for reaching the energy poor. However, to date only a few empirical evaluations exist which analyze and compare the impact of these projects on local living conditions and their sustainability ex-post implementation.
To better understand the impacts and the conditions that influence sustainability of these projects, the research presented in this paper evaluated 23 local development projects post implementation. By applying an standardized evaluation design to a cross-sectional sample in terms of renewable energy sources (solar, wind, biomass, hydro), user needs (electricity, food preparation, lighting, productive uses), community management models, finance mechanisms and geographical locations, the review results provide valuable insights on the underlying conditions that influence the success or failure of these small-scale local energy interventions. The empirical evidence suggests that the sustainability of small-scale energy implementations (≤100 kW) in developing countries is determined by the same factors, independent of the socio-cultural, political and ecological context. These findings allow to better predict the long-term success of small sustainable energy projects in developing countries, this can help to improve project designs and increase the certainty for future investment decisions.
The water-energy-food (WEF) nexus is increasingly recognised as a conceptual framework able to support the efficient implementation of the Sustainable Development Goals (SDGs). Despite growing attention paid to the WEF nexus, the role that renewable energies can play in addressing trade-offs and realising synergies has received limited attention. Until now, the focus of WEF nexus discussions and applications has mainly been on national or global levels, macro-level drivers, material flows and large infrastructure developments. This overlooks the fact that major nexus challenges are faced at local level. Aiming to address these knowledge gaps, the authors conduct a systematic analysis of the linkages between small-scale energy projects in developing countries and the food and water aspects of development. The analysis is based on empirical data from continuous process and impact evaluations complemented by secondary data and relevant literature. The study provides initial insights into how to identify interconnections and the potential benefits of integrating the nexus pillars into local level projects in the global south. The study identifies the complex links which exist between sustainable energy projects and the food and water sectors and highlights that these needs are currently not systematically integrated into project design or project evaluation. A more systematic approach, integrating the water and food pillars into energy planning at local level in the global south, is recommended to avoid trade-offs and enhance the development outcomes and impacts of energy projects.
The mass roll out of solar PV across the Global South has enabled electricity access for millions of people. In the right context, Small Wind Turbines (SWTs) can be complementary, offering the potential to generate at times of low solar resource (night, monsoon season, winter, etc.) and increasing the proportion of the total energy system that can be manufactured locally. However, many contextual factors critically affect the viability of the technology, such as the extreme variability in the wind resource itself and the local availability of technical support. Therefore, performing a detailed market analysis in each new context is much more important. The Wind Empowerment Market Assessment Methodology (WEMAM) is a multi-scalar, transdisciplinary methodology for identifying the niche contexts where small wind can make a valuable contribution to rural electrification. This paper aims to inform the development of WEMAM with a critical review of existing market assessment methodologies. By breaking down WEMAM into its component parts, reflecting upon its practical applications to date and drawing upon insights from the literature, opportunities where it could continue to evolve are highlighted. Key opportunities include shifting the focus towards development outcomes; creating community archetypes; localised studies in high potential regions; scenario modelling and MCDA ranking of proposed interventions; participatory market mapping; and applying socio-technical transitions theory to understand how the small wind niche can break through into the mainstream.
In many developing countries large parts of the population are negatively affected by the lack of access to clean and affordable energy. Providing sustainable energy services to these people has been acknowledged as a key component to reduce poverty. One form of development assistance to address the needs of the energy-poor at the local level are small-scale renewable energy projects. Like all development interventions, these energy projects are not intended to produce short-term outputs, but to create long-term impacts. Thus, it has become increasingly important to evaluate and accurately assess their sustainability. But despite the widely recognized need to identify successes factors and explain failure only few studies exist that address the sustainability of small-scale of energy development efforts post implementation. Against this background the paper presents the results of a post-evaluation of 23 projects supported via the Sustainable Energy Project Support (SEPS) scheme of the WISIONS initiative run by the Wuppertal Institute. The analysis provides insights on the influence that socio-economic, environmental, geographic and gender factors can have on the sustainability of small-scale renewable energy projects in developing countries.
Access to clean and affordable modern energy services has been widely recognised as a significant factor for enabling social and economic development. Stand-alone systems and mini-grids are presumed to play an important role in the provision of sustainable energy to those people who currently lack access. Accordingly, an increasing number of small-scale energy projects are being implemented in developing countries and emerging economies. However, despite the large number of energy development projects, only limited evidence exists about the actual contribution they make to sustainable development. This paper addresses this research gap by providing a systematic assessment of three selected impact pathways based on the evaluation of over 30 small-scale sustainable energy projects. Applying a theory-based evaluation approach in the form of a contribution analysis, the aim of this research is to better understand if and how these types of technical interventions can create development outcomes and impacts. The results show that technological issues are often not the most decisive factor in achieving development effects, but that embedding the technology in a set of actions that address social, cultural, economic and environmental aspects is essential.
Sustainable energy technologies are widely sought-after as essential elements in facing global challenges such as energy security, global warming and poverty reduction. However, in spite of their promising advantages, sustainable energy technologies make only a marginal contribution to meeting energy related needs in both industrialised and developing countries, in comparison to the widespread use of unsustainable technologies. One of the most significant constraints to their adoption and broad diffusion is the socio-economic context in which sustainable energy technologies are supposed to operate. The same holds true for community-based energy projects in developing countries supported by the WISIONS initiative. Practical strategies dealing with these socio-economic challenges are crucial elements for project design and, particularly, for the implementation of project activities. In this paper experiences from implementing community-based projects are reviewed in order to identify the practical elements that are relevant to overcome socio-economic challenges. In order to systematise the findings, an analytical framework is proposed, which combines analytical tools from the socio-technical transition framework and insights from participative approaches to development.
It is widely recognised that access to sustainable and affordable energy services is a crucial factor in reducing poverty and enhancing development. Accordingly, various positive effects beyond simple access to energy are associated with the implementation of sustainable energy projects. One of these assumed positive outcomes is the productive use of energy, which is expected to create value - for example in the form of increased local availability of goods or higher incomes - thereby having a positive impact on local livelihoods. Many projects and programmes are based on such expectations regarding the productive use of energy but systematic evidence of these outcomes and impacts is still limited. This study analyses the results of an impact evaluation of 30 small-scale energy development projects to better understand whether and how the supply of sustainable energy services supports productive use activities and whether these activities have the expected positive impacts on local livelihoods. A contribution analysis is applied to systematically evaluate the impact pathways for the productive use of energy. The results show that access to sustainable energy does not automatically result in productive activities and that energy is only one of the input factors required to foster socio-economic development. Furthermore, the results demonstrate that activities, materials and information to support the productive use of energy - such as training, equipment or market research - need to be an integrated part of the energy project itself to allow for productive activities to develop on a wider scale.
Status and future dynamics of decentralised renewable energy niche building processes in Argentina
(2018)
Despite significant natural potential for renewable energy in Argentina and the political intention to generate 8% of electricity from renewable sources by 2017, by 2016 the share was only 1.95%. Although this aggregated picture appears unfavourable, several diverse initiatives promoting the development and application of decentralised renewable energy technologies are in place across the country. The aim of this study is to characterise those initiatives promoting decentralised renewable energy and to assess their potential role in inducing the wider transformation of the Argentinian energy system. To achieve this, we apply conceptualisations for the development of sociotechnical niches and use qualitative research techniques to characterise the sociotechnical dynamics of the decentralised renewable energy sector in Argentina. A niche in an advanced stage of development, in which lessons are systematically aggregated in networks, was identified and examples of generic lessons being used to frame new projects or programmes were also found. In addition to considering the internal niche development processes, we investigate how external factors affect the development of the niche. Finally, we suggest two possible development pathways by which the niche might exert stronger influence on the broader sustainability transformation of the Argentinian power system.
There is significant potential for family farming to contribute to several dimensions of the Sustainable Development Goals adopted by the United Nations General Assembly in 2015. Our research aims to provide insights to help strengthen sustainable family farming. We focus on initiatives that have advanced sustainable family farming innovations in Colombia and analyse the factors and dynamics that have led to the limited penetration of those innovations across the country. To that aim, a transformative methodology is applied involving representatives of farmers' associations, supporting organisations and researchers from various disciplinary fields. We analyse the network of initiatives against the conceptual background of sociotechnical niches and identify a stable niche where generic lessons are being systematically identified and used to establish replication projects. However, this niche is still limited in its breadth, which results in a low capacity for expansion and a strong dependency on international donors for reproducing experiences. Specific recommendations are outlined for broadening the type of actors involved in the interpretation and dissemination of lessons from the niche. Moreover, we outline suggestions for further research and conceptualisation in two directions: for exploring effective ways of broadening the niche and translating niche lessons to state policies and for deepening the understanding of interactions between the niche and other levels.
Organic waste to energy (OWtE) technologies have been developed and implemented in Latin America and the Caribbean (LAC) countries. However, they are still far away to significantly contribute not only to treat the ever-increasing waste volumes in the region but also to supply the regional energy demand and meet national carbon emission goals. The technical complexity of these technologies aligned with lack of research, high investment costs and political deficiencies have not allowed for an appropriate implementation of OWtE in the region, where the applicability of large-scale plants remains to be demonstrated. This research presents the state-of-the art of OWtE technologies in the context of the LAC countries based on archival research method. In addition, it presents challenges and opportunities that the region is facing for an adequate implementation of these technologies. The main findings show that OWtE have the potential to improve waste and energy systems in the region by reducing environmental impacts along with a series of social and economic benefits, such as increasing access to a sustainable energy supply. Diverse researches indicate principally anaerobic digestion, fermentation (e.g. 2G bioethanol, etc.), microbial fuel cells, gasification and pyrolysis as efficient technologies to treat solid organic wastes and produce bioenergy.
