Prices of conventional and renewable energy as determinants of sustainable and secure energy development: regression model analysis

Background The prices of energy resources are important determinants of sustainable energy development, yet associated with significant unknowns. The estimates of the impact of prices of energy products in the domestic market (for domestic consumers) are rare—hence the importance and novelty of this research. Therefore, the main goal of the paper is to assess the impact of domestic prices of gasoline, gas, coal, and solar energy on sustainable and secure energy future. Methods The research includes 14 countries (of which 7 are developed and 7 are developing countries) and a period of 5 years (2014–2018). The model also includes discrete variables: level of development (developing or developed), and the fact as to whether the country is an energy exporter or not. For the purposes of analysis, the following elements were used: Panel Data Analysis, Linear regression (with random and fixed effects), Durbin–Wu–Hausman test, and Honda test, with the use of R-studio software for statistical computing. Results The research showed that the biggest negative impact on energy sustainability was recorded by an increase in the price of coal and the smallest one by an increase in the price of solar energy. An increase in the price of gasoline has a positive impact, while an increase in the price of gas has no impact. The basic methodological result showed that the fixed effects linear model is more accurate than the random effect model. Conclusions The results of the paper, important as a sustainable energy policy recommendation, showed that the impact of changes in energy product prices is significantly greater in developing countries, but that the status of the country as an energy exporter has no significance. In addition, the paper points to the need to intensify the research on the assessment of the impact of energy product prices for domestic consumers on their ability to pay that price, because with a certain (so far undefined) increase in energy product prices, a certain group of domestic consumers moves into a category that is not in line with sustainable energy development and is extremely undesirable in every respect—energy poverty.

The value of community technology workers for LPG use: A pilot in Shirati, Tanzania

Background Sustainable Development Goal (SDG) 7 calls for the adoption and continued use of clean-burning stoves by the 2.9 billion people relying on unclean fuels (both solid biomass and kerosene). However, to date, the clean cooking literature has found low rates of efficient stove adoption and continued use. This paper presents the application of a public health community engagement model to the use of clean cooking fuels. We implemented a pilot study with Community Technology Workers (CTWs) as a means to overcome maintenance, education, and behavioral barriers to clean fuel use in rural Tanzania. Methods The intervention was a free 6 kg Liquified Petroleum Gas (LPG) cylinder and stove coupled with education from a local technically trained CTW on LPG use. We evaluated the training, work, and impact of a CTW on LPG use on 30 randomly selected households from two villages in a rural district of Tanzania over a 1-year period. After an initial baseline survey, technically trained local CTWs educated the households on safe LPG use and conducted 34 follow up surveys over the next year on their cooking fuel use. Additionally, we conducted qualitative interviews with all households and a focus group with six of the households. Results The results from the mixed methods approach show that 80% of families (n = 24) consistently refilled their LPG cylinders and ~ 40% of households exclusively used LPG. Households reported appreciating the CTWs’ visits for providing education and maintenance support, giving them confidence to use LPG safely, reminding them to save for their cylinder, and providing a community driven effort to use clean fuel. Conclusions The findings demonstrate the feasibility of this type of community infrastructure model to promote and facilitate consistent LPG use, but suggest the need to couple this local support with financial mechanisms (e.g., a microsavings program). This model could be a mechanism to increase LPG use, particularly in rural, low-income areas.

Assessing the social acceptance of key technologies for the German energy transition

Background The widespread use of sustainable energy technologies is a key element in the transformation of the energy system from fossil-based to zero-carbon. In line with this, technology acceptance is of great importance as resistance from the public can slow down or hinder the construction of energy technology projects. The current study assesses the social acceptance of three energy technologies relevant for the German energy transition: stationary battery storage, biofuel production plants and hydrogen fuel station. Methods An online survey was conducted to examine the public’s general and local acceptance of energy technologies. Explored factors included general and local acceptance, public concerns, trust in relevant stakeholders and attitudes towards financial support. Results The results indicate that general acceptance for all technologies is slightly higher than local acceptance. In addition, we discuss which public concerns exist with regard to the respective technologies and how they are more strongly associated with local than general acceptance. Further, we show that trust in stakeholders and attitudes towards financial support is relatively high across the technologies discussed. Conclusions Taken together, the study provides evidence for the existence of a “general–local” gap, despite measuring general and local acceptance at the same level of specificity using a public sample. In addition, the collected data can provide stakeholders with an overview of worries that might need to be addressed when planning to implement a certain energy project.

Indicators for the optimization of sustainable urban energy systems based on energy system modeling

Background Urban energy systems are responsible for 75% of the world’s energy consumption and for 70% of the worldwide greenhouse gas emissions. Energy system models are used to optimize, benchmark and compare such energy systems with the help of energy sustainability indicators. We discuss several indicators for their basic suitability and their response to changing boundary conditions, system structures and reference values. The most suitable parameters are applied to four different supply scenarios of a real-world urban energy system. Results There is a number of energy sustainability indicators, but not all of them are suitable for the use in urban energy system optimization models. Shortcomings originate from the omission of upstream energy supply chains (secondary energy efficiency), from limited capabilities to compare small energy systems (energy productivity), from excessive accounting expense (regeneration rate), from unsuitable accounting methods (primary energy efficiency), from a questionable impact of some indicators on the overall system sustainability (self-sufficiency), from the lack of detailed information content (share of renewables), and more. On the other hand, indicators of absolute greenhouse gas emissions, energy costs, and final energy demand are well suitable for the use in optimization models. However, each of these indicators only represents partial aspects of energy sustainability; the use of only one indicator in the optimization process increases the risk that other important aspects will deteriorate significantly, eventually leading to suboptimal or even unrealistic scenarios in practice. Therefore, multi-criteria approaches should be used to enable a more holistic optimization and planning of sustainable urban energy systems. Conclusion We recommend multi-criteria optimization approaches using the indicators of absolute greenhouse gas emissions, absolute energy costs, and absolute energy demand. For benchmarking and comparison purposes, specific indicators should be used and therefore related to the final energy demand, respectively, the number of inhabitants. Our example scenarios demonstrate modeling strategies to optimize sustainability of urban energy systems.

Mapping emergent public engagement in societal transitions: a scoping review

Background Transition discourses are gaining prominence in efforts to imagine a future that adequately addresses the urgent need to establish low carbon and climate resilient pathways. Within these discourses the ‘public’ is seen as central to the creation and implementation of appropriate interventions. The role of public engagement in societal transformation while essential, is also complex and often poorly understood. The purpose of this paper is to enhance our understanding regarding public engagement and to address the often superficial and shallow policy discourse on this topic. Main text The paper offers a review of evolving literature to map emergent public engagement in processes of transition and change. We adopt a pragmatic approach towards literature retrieval and analysis which enables a cross-disciplinary and cross-sectoral review. We use a scoping review process and the three spheres of transformation framework (designated as the practical, political and personal spheres) to explore trends within this complex research field. The review draws from literature from the last two decades in the Irish context and looks at emergence and evolving spaces of public engagement within various systems of change including energy, food, coastal management and flood adaptation, among others. Conclusions The results highlight the siloed and fragmented way in which public engagement in transitions is carried and we propose a more cross-sectoral and cross-disciplinary approach which depends on bringing into dialogue often contrasting theories and perspectives. The paper also illustrates some shifting engagement approaches. For instance, nexus articles between the practical and political spheres suggest deeper forms of public engagement beyond aggregated consumer behaviour to align technological delivery with institutional and societal contexts. While most articles in the practical sphere draw largely on techno-economic insights this influence and cross-disciplinarity is likely to draw in further innovations. Nexus articles between the political and personal sphere are also drawing on shifting ideas of public engagement and largely stress the need to disrupt reductive notions of engagement and agency within our institutions. Many of these articles call attention to problems with top-down public engagement structures and in various ways show how they often undermine and marginalise different groups.

Climate change in the Western Balkans and EU Green Deal: status, mitigation and challenges

Background The European Commission (EC), based on the European Green Deal (2019) and the Recovery plan for Europe (2021), envisages investing 30% of the budget in climate-related programs, projects, and initiatives, which clearly shows Europe's commitment to becoming the first climate-neutral region by 2050. Activities are also planned for countries that are not members of the European Union (EU), which require complex changes in the field of legislation, strategic planning, implementation, and monitoring. To successfully plan short-term and long-term activities on these grounds, it is necessary to have a realistic picture of the state of climate change in each country—as they spill over into the entire region of Europe. The main objective of this paper is to answer the following questions: (i) is climate change observed in Western Balkans? (ii) how are certain sectors vulnerable to climate change in Western Balkans? (iii) what are the climate change adaptation strategies in the six countries of the Western Balkans? The answers to these questions can help in planning activities and initial alignment of Western Balkan countries with the EU plan to achieve net zero greenhouse gas (GHG) emissions by 2050. Main body The main results of the research show that in all countries of the region, the average annual temperature increased by 1.2 °C compared to 1970, with stabilization and the beginning of the decline which can be expected around 2040. The main reasons for climate change in the region are: industry, energy, and heating sector based on coal exploitation, low energy efficiency, etc. Conclusions It can be concluded that Croatia as a member of the EU has adopted, and other five Western Balkans countries are in the process of adopting the necessary regulations and strategies towards climate change mitigation, but the implementation of specific activities is at a low level. The reason for this most often lies in the insufficient commitment of decision-makers to make significant changes in the field of climate change transition (lower level of economic development, lack of investment, and preservation of social peace). Finally, this paper provides an overview of climate change by country, scenario analysis, and policy recommendations.

Digitalisation and sustainable energy transitions in Africa: assessing the impact of policy and regulatory environments on the energy sector in Nigeria and South Africa

Background Digital technologies have unique characteristics for achieving radically disruptive transitions within the energy sector. They provide opportunities for new production and consumption models between micro-producers and consumers of electricity within communities in a way that transforms the traditional energy generation and consumption model. The study critically assessed the digitalisation of energy systems in Africa within the context of existing policy frameworks in the quest to achieve sustainable energy transitions in Africa. It investigated how digital technologies such as blockchain, digital platforms and smart grids were adopted and implemented within the energy sector to achieve new energy production and consumption models that are both environmentally sustainable and socially inclusive. This assessment was done within the context of existing policy and regulatory frameworks of the society where the use cases were domiciled. Methods The aim of the research was to investigate how sustainable energy transitions are being achieved in Nigeria and South Africa through the digitalisation of energy systems. A qualitative methodological approach was done in three stages—a document analysis that reviewed relevant literature on the energy sector policies in Nigeria and South Africa; the next step involved a comparative case study conducted to assess the characteristics of digital technology deployment in each country’s energy transition. Finally, outcomes of the comparative case studies were then situated within the context of existing policies within the countries covered by the study. Results Results from the research indicate that Africa is still in the early stages of adoption and application of digital technologies such as blockchain and smart grids within the energy sector. The results also showed a disconnect between the policy environment and industry efforts at achieving this. The current applications as exemplified in the use cases by the three companies covered in this study indicates that Africa's sustainable energy transition is in a rudimentary or early adoption stage, and they are not currently aided by the policy environments in which such projects are domiciled. Conclusions The research provides deep insights into the current state and developments within the energy sector especially in relation to how digital technologies are being adopted and implemented in solving the energy poverty prevalent across sub-Saharan Africa.

Sustainable energy transition in Central Asia: status and challenges

Background The paper aims at gaining insight into the implementation of the process of sustainable energy transition in the countries of Central Asia: Kazakhstan, Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan. Information and scientific studies on the situation in these countries is scarce. On the other hand, these are resource-rich countries, some are exporters, and all are energy transit countries. The main aim of the paper was realized by applying the energy policies and regulatory framework analysis, defining priorities and monitoring selected indicators prescribed by the International Energy Agency. Methods The following methods were used in the quantitative analysis: measurement of data intercorrelation; Pearson test of correlation; principal component analysis (with rotation method: Oblimin with Kaiser normalization); Kaiser–Meyer–Olkin measure of sampling adequacy, Bartlett’s test of sphericity and t-test. The period covered by the quantitative analysis: 1990–2018, provided that the available data for 2019 or 2020 were used in certain cases. Results Sustainable energy transition is, at the analysis of policies and data, at a low level. There is no adequate regulatory framework in these countries. The energy transition takes place exclusively within the framework of providing enough energy, without regard to sustainability, while even energy exporting countries are not making efforts to achieve a sustainable energy transition. Conclusions There are no indications that the energy transition in the countries of Central Asia will take place according to the standards of the European Union or global bodies. On the other hand, having in mind the natural resources of the mentioned countries and the specific geopolitical position, monitoring the changes is of special importance. The impact of changes on sustainability can be determined mainly ex post.

Electrical energy transition in the context of Ghana

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.

Net zero 2050 as an EU priroty: modeling a system for efficient investments in eco innovation for climate change mitigation

Background The study background is based on the fact that The Recovery Plan for Europe envisages investing 30% of the huge budget in climate change, with the goal of zero gas emission by 2050. This ambitious plan will require (for now indefinitely) investments in research and innovation. The study’s main objective is to check and analyze the existing and propose a new model of effective investments in eco-innovation. This will contribute to effective long-term investment policy, climate change impact, and mitigation of consequences. Methods The basic methodological tools for solving the problems discussed in this study were correlation analysis, regression analysis, and paired sample t-test. All calculations were performed in the SPSS 20 statistical software. Time series data of the selected indicators were obtained from the European Innovation Scoreboard 2020. The database used to collect the data for the EU member countries and selected third countries for the analysis is the European Innovation Scoreboard 2020. To avoid sample selection bias, the authors considered all of the available data for all the member countries and selected third countries in the European Innovation Scoreboard 2020 for the 2012 to 2019 period. Results The study results show the path developing countries should follow in directing their inevitable and increasing eco-innovation investments, taking into account the arguments of structural differences in financing Research and Development (R&D). The authors’ findings support the thesis that investments in R&D is low in developing countries, while in developed EU countries, there are more investments in R&D from the business sector for the 2012–2019 period. Conclusions Study conclusions are summarized as a proposal of the appropriate R&D financing model approach to developing countries with a greater share of eco-innovation and self-sustainable R&D financing for climate preserving products. This study is important as it provides new evidence on financing R&D investments in innovation leader countries and emerging innovator countries according to Summary Innovation Index.
