    Description: 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.

    Description: 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.

    Description: The Paris Agreement calls on all nations to pursue efforts to contribute to limiting the global temperature increase to 1.5 °C above pre-industrial levels. However, due to limited global, regional and country-specific analysis of highly ambitious GHG mitigation pathways, there is currently a lack of knowledge about the transformational changes needed in the coming decades to reach this target. Through a meta-analysis of mitigation scenarios for Germany, this article aims to contribute to an improved understanding of the changes needed in the energy system of an industrialized country. Differentiation among six key long-term energy system decarbonization strategies is suggested, and an analysis is presented of how these strategies will be pursued until 2050 in selected technologically detailed energy scenarios for Germany. The findings show, that certain strategies, including the widespread use of electricity-derived synthetic fuels in end-use sectors as well as behavioral changes, are typically applied to a greater extent in mitigation scenarios aiming at high GHG emission reductions compared to more moderate mitigation scenarios. The analysis also highlights that the pace of historical changes observed in Germany between 2000 and 2015 is clearly insufficient to adequately contribute to not only the 1.5 °C target, but also the 2 °C long-term global target.

    Description: 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.

    Description: Nach den G7-Beschlüssen von Elmau und dem Klimaabkommen von Paris im Jahr 2015 ist das Thema der langfristigen Dekarbonisierung der Energiesysteme der Industrieländer in den Vordergrund der politischen und wissenschaftlichen Diskussion gerückt. Japan und Deutschland stehen als führende Industrienationen vor ähnlichen Herausforderungen, gleichzeitig können sich aber auch für beide Länder wirtschaftliche Entwicklungschancen aus der Dekarbonisierung ergeben. Aus diesem Grund bietet sich eine verstärkte Kooperation und die Initiierung gegenseitiger Lernprozesse besonders an. Die vorliegende Metaanalyse ambitionierter Klimaschutzszenarien für Japan und Deutschland stellt mit der Diskussion von langfristigen Dekarbonisierungsstrategien in beiden Ländern einen ersten Schritt in diese Richtung dar. Die quantitative Analyse hat gezeigt, dass die Untersuchungsschwerpunkte der Szenarien - sowohl für Deutschland als auch für Japan - vielfach auf den THG-Emissionen des Energiesystems liegen. Die THG-Emissionen anderer Sektoren werden seltener und wenn, dann oft in geringerer Detailtiefe berücksichtigt. Der Vergleich von ambitionierten Dekarbonisierungsszenarien mit THG-Minderungszielen von 80 bis 100 Prozent zeigt in vielen Bereichen für Japan und Deutschland tendenziell recht ähnliche Entwicklungen und Strategien auf. Es wird deutlich, dass in beiden Ländern erhebliche Änderungen insbesondere im Energiesystem notwendig sind, um die anvisierten mittel- und langfristigen THG-Minderungsziele zu erreichen. Es werden ähnliche Annahmen zu Bevölkerungsentwicklung und Wirtschaftsentwicklung getroffen und es werden vergleichbare Entwicklungstrends bei vielen Ausprägungen des Energiesystems deutlich. Unterschiede zwischen den deutschen und japanischen Szenarien sowie zwischen den Szenarien der einzelnen Länder bestehen hingegen vor allem in Bezug auf Geschwindigkeit, Umfang und die Zusammensetzung der Strategieelemente.

    Description: Der Schutz des Klimas und die dafür erforderliche Umstellung der Energieversorgung auf erneuerbare Energien ist eine globale Herausforderung, welche nach maßgeschneiderten Lösungen für die unterschiedlichen Klimazonen und Märkte der Erde verlangt. Die verstärkte Solarenergienutzung spielt dabei eine maßgebliche Rolle. Die Rolle Deutschlands als Exportnation beschränkt sich hierbei nicht auf die Klimawende im eigenen Land, sondern beinhaltet auch den weltweiten Export erneuerbarer Energietechnologien. Die Kosten der photovoltaischen Stromerzeugung (PV) und der Windkraft sind in den vergangenen Jahren erfreulicherweise deutlich gesunken, entsprechend wurden in vielen Ländern große Kapazitäten zugebaut. Die resultierende stark gestiegene Einspeisung fluktuierender Erzeuger stellt Netzbetreiber vor neue Herausforderungen, insbesondere durch die extremen Lastschwankungen für plan- und steuerbare, heute größtenteils fossil befeuerte konventionelle Kraftwerke. Hier bieten solarthermische Kraftwerke Lösungen.
