This study investigates the effect of unproven energy reserve news on the volatility of energy firms' stocks. Thus, investors' perception of unproven energy reserves is revealed. Additionally, the study aims to determine whether the effect of the news changes according to time and volatility level.

The general autoregressive conditional heteroskedasticity (GARCH) and exponential generalized autoregressive conditional heteroskedasticity (EGARCH) models consist of the energy reserve exploration news in Turkey for the period 2009–2022 and the volatility of 14 energy stocks.

The results indicate energy exploration news's negative and significant effect on volatility. According to empirical results, energy stock volatility is most affected in the first ten days. Besides, the results show that the significant models of energy reserve news in low-volatility stocks are proportionally higher than in high-volatility stocks.

Only unproved reserve news is included in the analysis, as sufficient confirmed reserves could not be reached during the sampling period. Further studies can compare proven and unproved reserve news effects. Additionally, a similar analysis can be conducted between Turkey and another country with a similar socio-economic character to examine different investor behaviors.

This research includes indications on managing investors' reactions to unproven energy reserve news.

This study contributes to the literature by analyzing unproven reserves. Contrary to previous studies, examining stock volatility also makes the study unique.

This chapter aims to identify new perspectives of geothermal energy investments. For this purpose, all studies in the Web of Science regarding the geothermal energy are taken into consideration. These studies are evaluated with the help of text-mining approach. In this framework, most frequently stated words, two words, and three words are identified. It is concluded that technological development with respect to the geothermal energy is an important issue in this framework. After that, it is also determined that risk is another important factor in this regard. Finally, new implications regarding the geothermal energy are also considered by the researchers. Geothermal energy has a positive contribution to solve many different problems, such as energy dependency, current account deficit problem, and carbon emission. Hence, this study generated the significant issues to improve these investments. While considering the results, it is understood that technological developments related to the geothermal energy projects should be followed effectively. In addition, an effective risk evaluation should be conducted before implementing these projects.

The purpose of this paper is to compile a comprehensive status report on pipes/piping networks across different industrial sectors, along with specifications of materials and sizes, and showcase welding avenues. It further extends to highlight the promising friction stir welding as a single solid-state pipe welding procedure. This paper will enable all piping, welding and friction stir welding stakeholders to identify scope for their engagement in a single window.

The paper is a review paper, and it is mainly structured around sections on materials, sizes and standards for pipes in different sectors and the current welding practice for joining pipe and pipe connections; on the process and principle of friction stir welding (FSW) for pipes; identification of main welding process parameters for the FSW of pipes; effects of process parameters; and a well-carved-out concluding summary.

A well-carved-out concluding summary of extracts from thoroughly studied research is presented in a structured way in which the avenues for the engagement of FSW are identified.

The implications of the research are far-reaching. The FSW is currently expanding very fast in the welding of flat surfaces and has evolved into a vast number of variants because of its advantages and versatility. The application of FSW is coming up late but catching up fast, and as a late starter, the outcomes of such a review paper may support stake holders to expand the application of this process from pipe welding to pipe manufacturing, cladding and other high-end applications. Because the process is inherently inclined towards automation, its throughput rate is high and it does not need any consumables, the ultimate benefit can be passed on to the industry in terms of financial gains.

To the best of the authors’ knowledge, this is the only review exclusively for the friction stir welding of pipes with a well-organized piping specification detailed about industrial sectors. The current pipe welding practice in each sector has been presented, and the avenues for engaging FSW have been highlighted. The FSW pipe process parameters are characteristically distinguished from the conventional FSW, and the effects of the process parameters have been presented. The summary is concise yet comprehensive and organized in a structured manner.

This paper aims to explore the socio-political implications of climate change as the melting ice ignites new debates over territorial sovereignty of Arctic coastal states. Previously ice-jammed waterways are now open, and a number of recent geological surveys have identified new potential sites with vast energy resources. Competition over resources causes states to question each other’s jurisdiction over specific parts of the Arctic. What used to be internal waters of one particular state can now be referred to as international waters by other actors interested in the benefits of resource extraction. Arctic indigenous groups, especially the Inuit, and Sami are directly affected by the current governance patterns that are fragmented across too many different bodies dealing with maritime navigation, tourism, fisheries and administration.

The paper uses a comparative study based on literature review combined with regional reports related to climatic and social impacts analysed jointly with live elements provided by international conferences discussions, workshops and direct conversations in “petit comités” style held in Norway, Greenland and Canada in the period of October 2014 until the first quarter of July 2015, with the representatives of Sami and Inuit communities.

The paper demonstrates that Arctic governance is currently fragmented and the largest inter-governmental organisation in the region, the Arctic Council, has only advisory powers, and although its norm-making method helps with the design, it is not effective to implement Arctic-wide policies for responsible management of energy resources.

The research considered methodological aspects like the difficulty in measuring the elements researched mainly when dealing with the diverse nature of responses from the indigenous populations to environmental impacts and the varied nature of effects in different studied areas.

As the Arctic is set to become the main global resource base and a major trade corridor, it is crucial to identify the dangers that poor institutional design can cause in relation to the control of extractive industries, sustainable development and the well-being of the region’s indigenous population.

In addition to governance reform, social arrangements should follow to ensure the indigenous populations can also participate in the process to adapt and mitigate the impact of climate change on their traditional livelihood strategies.

The paper provides an overview on governance reform and social arrangements to ensure that indigenous populations can also participate in the process to adapt and mitigate the impact of climate change on their traditional livelihood strategies. As the Arctic is set to become the main global resource base and a major trade corridor, the paper identified the risks of poor institutional design in relation to the control of extractive industries, sustainable development and the well-being of the region’s indigenous population.

The purpose of this study is to contribute to the scarce body of academic research on corporate social responsibility (CSR) in BRIC countries and Russia in particular, by performing a comparative analysis of CSR, reporting of ten major players in the energy sector in the USA and Russia.

This study applies a content analysis research design in order to obtain an in-depth understanding of the key themes communicated in the reports. Drawing on an institutional approach to CSR, this study attempts to explain revealed differences in CSR reporting in Russian and American companies.

The results suggest that Russian companies compared to American ones report more extensively on the areas of social performance and CSR issues related to employees and consumers. Nevertheless, American reports contain topics of global concern in the scope of environmental performance that are omitted by Russian companies.

The paper deepens the understanding of CSR reporting specificity related to an institutional context and suggests that CSR fills different needs in different types of societies.

The study contributes to the academic research on CSR in BRIC countries and provides some insights into how the revealed differences between Russian and American reports in the energy industry can be explained using an institutional approach.

The purpose of this paper is to investigate fast pyrolysis of maple fruit as an energy sources. This could serve as a solution to the energy sources problem.

Fast pyrolysis of maple fruit (samara) was achieved in a fixed bed reactor. The pyrolysis experiments have been conducted on the sample of maple seeds to particularly determine the effects of pyrolysis temperature, particle size and sweep gas flow rate on the pyrolysis product yields.

The oil of maple fruit from fast pyrolysis has good properties to be a potential candidate as a biofuel or as a source of chemicals. In addition to being environmentally desirable, it can reduce the energy cost, e.g. that Turkey imports a majority of its energy.

The use of maple fruit for fast pyrolysis and pyrolysis conditions impact on the yields of pyrolysis liquid can be considered as novel aspects of this paper.

Energy policy and sector developments in Greece in the last decades reveal the government and investors' intentions to exploit the energy resources and production potential of the country. Developments regard renewable and hydrocarbon energy sources. Agreements with international companies come with economic terms attached and the prospect of related sectors' development, employment generation, research and innovation. Developments, particularly those related to hydrocarbons exploration, take place in times of climate change mitigation and adaptation and actions to ensure environmentally, socially, and economically sustainable development in line with the goals set out in the United Nations Agenda for 2030 and the European Green Deal. Given these challenges, the design and implementation of timely policies that can promote local supply capacity appear to be of primary importance. This chapter discusses the challenges and opportunities of designing and implementing local content policies with the intention to derive useful policy considerations. The discussion draws from the latest developments with hydrocarbons exploration and production activities in Greece and from the recent relevant to local content literature. The analysis concludes that in the face of climate action, rapid technological innovation, and the high capital intensity that characterize the sector, knowledge transfer, and education upgrade emerge as important factors of achieving sustainable growth through local content policies.

This paper aims to deepen our understanding on circumpolar current dynamics relating to oil and gas exploitation and the role of nations in the polar development process. Additionally, it is fundamental to raise the debate about the energy development in the Arctic and the fact that the exploration of oil and gas resources in the Arctic cannot be performed with the current governance regime, policies and legal framework. Arctic-specific natural ecosystems, the presence of indigenous communities and the commercial interest in the region will require an innovative model of development based on the highest level of responsible exploitation, diplomacy, regulation and policy-making.

This is an unexplored subject but the paper uses a review of past and recent literature, outcomes of recent “petit comités” with some of the involved parties, as a vehicle to discuss possible new approaches and paths for the future development of an innovative model of environmental governance relating to energy development in the Arctic region.

This paper demonstrates the necessity of improving the current governance patterns, as the author believes that energy development will have both positive and negative impacts on micro and macro levels. The first relevant contribution of these operations in the Arctic, undoubtedly, is the benefit for energy security levels at a global platform; however, the framework built up in terms of new legal cooperation agreements, policy-making and technological innovation in different areas will define the new Arctic citizenship as well as the Arctic’s geopolitics, and, consequently, the region’s destiny.

This is an unexplored subject, as it is an unexplored region. New literature about the region dynamics is being developed, as new licensing process is ongoing, and there are more questions than answers about open space for reflection and decision-making. Important data have not been published or shared in “petit comités” due to strategic interests and confidentiality reasons.

The major drivers of change could be described as energy security, climate change and transportation that will have a huge direct impact in the region under social, economic and environmental perspectives. The core practical implication of this reflection is the energy development model for the Arctic region.

How the Arctic’s energy resources will contribute to the global energy mix in the decades to come and the impacts of the governance regime to Arctic and non-Arctic societies is the first relevant question. Another fundamental aspect with huge social implications is how the climate changes will impact the Arctic environment and societies. These are themes that deserve more study and deeper analysis.

The paper provides a deep reflection of the challenges and future trends involving the new frontiers of the world energy exploration. Multidisciplinary dialogue and research on all aspects of offshore oil and gas development will require a shift in the current conceptual view of the Arctic as well as in the multilateral efforts to negotiate and design an efficient Arctic governance regime that goes beyond the setting of new standards of spill prevention, preparedness and safety, but a regime that congregates the Arctic and Non-Arctic nations’ experience, workforce and leadership.
