Deep Uncertainty

Methods of multi-criteria decision making (MCDM) from operations research have been applied to provide information for making long-term decisions in the energy sector, and energy policy. For example, in sustainability evaluations, multiple conflicting criteria can be considered. While most MCDM approaches have been applied to evaluate energy systems in a single period, the multi-criteria evaluation of energy system evolution over time has received less attention. To evaluate such transition paths, multi-period MCDM approaches can be used. Because of long-term planning horizons, deep uncertainties need to be considered. Based on prior multi-period MCDM approaches, this paper provides an extension of the outranking approach preference ranking and organization method for enrichment evaluations (PROMETHEE) for multi-period evaluations in deep uncertainty settings. In order to adequately address the consideration of uncertainties and to obtain an additional level of information, a multi-period PROMETHEE approach and scenario planning are combined. In an illustrative example, this method is applied to a case study from the German energy sector regarding a renewable energy transition. This highlights the potential interactions of a multi-period perspective and the consideration of external scenarios in the decision-making process.

Abstract Background In Ghana, energy transition as a research theme is new. It is unclear whether energy transition has occurred or not, and if so, in what form. This study sought to find out whether this transition has occurred in Ghana’s electrical energy sector and how using indicators deduced from literature, such as change in energy source type, change in energy ownership and management, and transition to greener vehicular transportation. Methods Information on Ghana’s electrical energy transition was obtained from thematic content analysis of Ghana’s renewable energy policy documents, energy sector reports, newspaper articles and information on the websites of Ghana’s energy sector institutions such as the Volta River Authority, Ghana Grid Company Limited, Electricity Company of Ghana and the Northern Electricity Distribution Company. Results In this study, it was demonstrated that two structural changes have occurred in Ghana’s electrical energy sector: (1) Transition from an exclusively hydro energy to a hydro-thermal mix, with thermal energy constituting about 69% of the 2020 generation mix; and (2) Transition from an exclusively state supplied energy to a state-private supply mix, with about 56% of the 2020 supply coming from private companies. These changes were motivated by the need to expand the energy supply in response to an increasing demand of 10–15% per year. The study also indicated that renewable energy had attracted attention in policy, with policy targets such as 10% renewable energy in the energy mix by 2030 and provision of renewable energy to 1000 off-grid communities by 2030. However, renewable energy currently constitutes less than 1% of the electrical energy mix. Also, there has been no change in the heavy reliance on fossil energy for vehicular transportation. Conclusions The study concludes that energy transition in its broad sense of structural changes in a country’s electrical energy system has occurred in Ghana, however a sustainable energy transition in the sense of a transition to greener energy has not occurred. It is recommended that further studies should be conducted on why Ghana’s renewable energy agenda has so far only been an agenda in policy with very minimal implementation in practice.

The relevance of the subject matter is conditioned upon the fact that currently the main direction of global energy development is already clearly visible: under the influence of changes in energy policy and the development of new technologies, the world is entering the stage of the fourth energy transition to the widespread use of renewable energy sources and displacement of fossil fuels. The development of Kazakhstan's economy requires the transition of energy towards clean and safe renewable sources, which will let the country build a new strong economy and break out of the long-running socio-economic decline, help the international community solve the problem of climate change and improve the safety and welfare of its citizens. The purpose of the study: The purpose of the paper is to develop recommendations for the development of Kazakhstan's energy industry at a new stage in the fundamental transformation of the global energy system. Leading approach to researching the problem. The leading methods of researching the problems of the paper include the analysis of theoretical sources, analysis of statistics, and comparison. Analysis of statistical indicators plays a crucial role in the study, since data on the development of Kazakhstan's energy industry can be directly obtained from statistical databases. The results of the study. The paper discusses the essence of the fourth energy transition, its main aspects, explores renewable energy sources, identifies the features and problems of Kazakhstan's energy industry, and develops ways to solve them. Prospects for further research. To implement the modern provisions of the fourth energy transition in Kazakhstan, it is necessary to use a systematic approach. The basic elements of such a transition are the introduction of renewable energy and energy efficiency (the intensification of reducing the energy intensity of goods and services). The materials of the paper are of practical value for the development of Kazakhstan’s energy during the period of fundamental structural transformations of the world energy sector.

Abstract Background Energy communities are emphasized by the EU as important for developing sustainable energy systems that include and engage many people. While many renewables are highly compatible with a more decentralized energy system, research indicates that participation in ‘desirable’ energy activities and energy decision-making is influenced by social and economic factors, including gender, economic status and home ownership. The overall aim of this article is to contribute to this line of inquiry by exploring how and under which conditions energy communities allow for broader participation in the energy system. This article examines how gender, as a more specific condition, influences the extent to which parties can or cannot engage with collective solar ownership models by means of a qualitative study of 11 solar energy communities and one housing association in Sweden. Results The study revealed that despite the relative potential for inclusion that they hold, energy communities can raise justice concerns in terms of inequities concerning access, capacity, and opportunity to engage in decision-making. Conclusions While solely focusing on gender offers a limited view of the dynamics of inclusion and exclusion in renewable energy projects, it is our position that integrating it into the analysis will provide insights into possible measures to remedy limitations and accelerate the renewable energy transition.

Serious structural changes in energy sector are expected in the next period. System long-term and fundamental changes we could simply call energy transition. There are two basic reasons for that: the first is caused by global flows influenced by climate changes and strategies, which are more complicated and very demanding; the second reason is situation in the energy sector and economic system in Serbia, especially in the environmental area and natural resources management. The losses and pollution costs, caused by energy sector, make Serbian energy one of the most neglected and the least promising in the region of south-eastern Europe. Serious structural changes in energy sectorare in big delay. Nowadays Serbia wastes the energy, in comparison, not only with more developed countries (OECD and EU) but with comparabl ecountries in the region. Every day Serbian economy and society emit more and more pollutants in environment, and the whole economic system suffers by losses of the energy. Populism as chronic problem of economic and energy policies is the logical consequence of incompetent political party’s management and weak economizing with energy potentials. System depoliticization, technology modernization and strategic greening of the whole energy system of Serbia are expected in the future. Sustainability of the processes in energy is long-term task that start swith gradual and difficult economic steps. More expensive, clearer and socially available energy is something that considers higher income and better life quality, but requires new energy culture of citizens, economy structure and state system.

AbstractCurrent development of renewable energy systems (RES) is characterised by an increasing participation of citizens in the upstream decision-making process. These citizens can be future users of the RES but also members of a Renewable Energy Community that develop RES. They can be at the same time Renewable Energy producer, investor and consumer. Moreover, several type of businesses and terms are used to cope with social innovations within the energy sector: local renewable projects, sustainable energy communities or community of renewable energy production. So, actors' engagement opens new solutions for designers who are induced to share alternatives before making decisions. They usually impose constraints since the early phases of the design process. This approach implies for designers to consider new criteria related to citizens motivations and barriers. This paper presents a study to define the main factors that drive people to contribute in social innovation schemes for clean-energy transition. After a state of the art, a survey about 6 main factors and 18 criteria is presented. The analysis based on the responses from 34 participants (i.e. experts) reveals 2 most important factors of motivation and 2 principal barrier sources.
