In the last two decades, studies that analyse the political economy of sustainable energy transitions have increasingly become available. Yet very few attempts have been made to synthesize the factors discussed in the growing literature. This paper reviews the extant empirical literature on the political economy of sustainable energy transitions. Using a well-defined search strategy, a total of 36 empirical contributions covering the period 2008 to 2022 are reviewed full text. Overall, the findings highlight the role of vested interest, advocacy coalitions and green constituencies, path dependency, external shocks, policy and institutional environment, political institutions and fossil fuel resource endowments as major political economy factors influencing sustainable energy transitions across both high income countries, and low and middle income countries. In addition, the paper highlights and discusses some critical knowledge gaps in the existing literature and provides suggestions for a future research agenda.
Recent findings in South Africa have once again underlined the fact that the oldest people in the world obviously came from Africa. Thus, historically, this continent has a very special significance. However, its history in more recent times, especially from the mid-19th century onwards, was strongly influenced by colonisation by European states. Many deep wounds from that time still have an impact on society as a whole today. However, the continent is currently also confronted with a greater number of challenges of a different nature.
On the one hand, Africa is trying to strengthen internal cohesion by means of a number of regional organisations and the African Union as a globally active institution; on the other hand, the continent has been marked by political and military conflicts between neighbouring states over the past decades until the recent present. In addition, there are regular internal social upheavals in individual countries due to violent or manipulated political change.
Yet the continent could well be on a good development path, since it has a large number of important raw materials - also in comparison to other continents. However, the individual African states - and especially their citizens - often do not benefit from this to an adequate extent. This results in a social imbalance in large parts of the continent (data collection until the end of June 2023), which leads to considerable internal tensions. To make matters worse, Africa is the continent most affected by climate change.
A closer look at the partly very different economic, political and social situations of the large continent leads to an overall predominantly critical assessment of Africa's further development, which is explained in more detail in the final chapter with regard to the foreseeable consequences for the continent.
Neueste Funde in Südafrika haben nochmals unterstrichen, dass die ältesten Menschen der Welt offensichtlich aus Afrika abstammen. Somit kommt diesem Kontinent historisch gesehen ganz besondere Bedeutung zu. Allerdings war seine Geschichte in der jüngeren Zeit, insbesondere ab Mitte des 19. Jahrhunderts, von der Kolonialisierung durch europäische Staaten stark geprägt. Viele tiefe Wunden aus der damaligen Zeit haben noch heute Auswirkungen auf die Gesellschaft insgesamt. Allerdings ist der Kontinent derzeit auch mit einer größeren Zahl anders gelagerter Herausforderungen konfrontiert.
Zum einen versucht Afrika mittels einer Anzahl von Regionalorganisationen sowie der Afrikanischen Union als global agierender Institution den inneren Zusammenhalt zu stärken, zum anderen ist der Kontinent über die letzten Jahrzehnte bis in die jüngste Gegenwart durch politische und militärische Konflikte zwischen Nachbarstaaten geprägt. Hinzu kommen regelmäßig innere gesellschaftliche Umwälzungen einzelner Länder durch einen gewaltsamen oder manipulierten politischen Wechsel.
Dabei könnte der Kontinent sich durchaus auf einem guten Entwicklungspfad befinden, verfügt er doch – auch im Vergleich zu anderen Kontinenten – über eine Vielzahl von wichtigen Rohstoffen. Allerdings profitieren die einzelnen afrikanischen Staaten – und insbesondere ihre Bürgerinnen und Bürger - hiervon oft nicht in einem angemessenen Rahmen. Somit ergibt sich in großen Teilen des Kontinents ein soziales Ungleichgewicht, das zu erheblichen inneren Spannungen führt. Erschwerend kommt hinzu, dass Afrika weltweit am stärksten vom Klimawandel betroffen ist.
Bei näherer Betrachtung der z.T. sehr unterschiedlichen wirtschaftlichen, politischen und sozialen Situation des großen Kontinents (Datenerhebung bis Ende Juni 2023) führt die vorliegende Untersuchung zu einer insgesamt überwiegend kritischen Einschätzung hinsichtlich der weiteren Entwicklung Afrikas, die im Schlusskapitel bzgl. der absehbaren Konsequenzen für den Kontinent näher dargelegt wird.
Estimates of global horizontal irradiance (GHI) from reanalysis and satellite-based data are the most important information for the design and monitoring of PV systems in Africa, but their quality is unknown due to the lack of in situ measurements. In this study, we evaluate the performance of hourly GHI from state-of-the-art reanalysis and satellite-based products (ERA5, CAMS, MERRA-2, and SARAH-2) with 37 quality-controlled in situ measurements from novel meteorological networks established in Burkina Faso and Ghana under different weather conditions for the year 2020. The effects of clouds and aerosols are also considered in the analysis by using common performance measures for the main quality attributes and a new overall performance value for the joint assessment. The results show that satellite data performs better than reanalysis data under different atmospheric conditions. Nevertheless, both data sources exhibit significant bias of more than 150 W/m2 in terms of RMSE under cloudy skies compared to clear skies. The new measure of overall performance clearly shows that the hourly GHI derived from CAMS and SARAH-2 could serve as viable alternative data for assessing solar energy in the different climatic zones of West Africa.
Background:
Access to electricity is one of the enabling factors for healthcare service provision. From the sustainable development perspective, an essential requirement for improving health and caring for our environment is to assure that health facilities have sufficient and reliable access to the supply of clean and sustainable energy. The objective of this work is to investigate the users’ perceptions of electricity needs and electricity sources and the way those influence different attributes and their relevance for the diffusion of renewable electricity systems in healthcare facilities.
Methods:
To identify preferences and choices, Stated Choice modelling was applied as the use of solar PV systems in health facilities is not widespread in Ghana. This method allows to present the respondents with hypothetical options, which have attributes close to the real world. Four attributes were considered, namely electricity system configuration, initial investment cost, monthly costs, and improvements to the reliability of the electricity supply.
Results:
The largest share of the 200 health facilities interviewed reported services provision as outpatient treatment, provision of maternity services and family planning, which are relatively low electricity-intensive services. However, there was a general perception that increased reliability on the electricity supply can improve the health service provision and operation of the facilities. Moreover, despite that preferences towards the solar systems, the initial investment costs of the solar systems is still perceived as preventing the adoption of this technology
Conclusion:
From this study we can conclude that health facilities in Ghana rely greatly on the national supply which has issues with reliability, compromising the delivery of healthcare services. However, the adoption of alternative electricity technologies based on renewable sources is not likely to occur at the facility level without the engagement of other actors that can help bridging the barriers for adoption, as initial investment costs.
