ABSTRACT Electricity prices are determined in wholesale markets. A major issue in determining prices is the distortive effect of high volatility of supply. This paper investigates the volatility of electricity supply in the Turkish energy exchange for the period between 2017 and 2020, by using hourly data. We find that volatility increased substantially during this period and uncertainty became a major issue. High volatility brings non-price variables such as institutional and political preferences to the forefront in terms of the decision-making of suppliers. We also discuss the dominance of bilateral contracts, the design of the renewable support mechanism, and the disappearance of independent traders in the wholesale market as some of the major issues that correlate with high volatility.

ABSTRACT The interdependence of carbon allowances and different energy sources in extreme market behavior is still unsettled in the literature. Using different types of static and time-varying copulas, this piece of research aims to quantify the dependence structures of Europe-based carbon future returns and selected energy future returns (i.e. coal, electricity, oil, and natural gas), and to investigate whether or not these dependence structures are influenced by economic indicators. Our results show strong evidence that time-varying parameter copulas with extreme tails are the best fit to the dependence structure. We also find that the speculation activity and the uncertainty of the state of the global economy are two important components of this robust dependence structure in the period of oil price crises. These findings are relevant for the implementation of effective policies to make the carbon market operate more efficiently and stably.

ABSTRACT At present, the development of some oil and gas fields has gradually shifted from vertical to highly deviated wells. To improve the intensity of reservoir reconstruction, highly deviated wells mostly adopt staged fracturing for reservoir reconstruction. The fracture interference law of multiple fractures in highly deviated wells is not clear, and the fracture steering and stress interference problems in the fracturing process are obviously different from those in horizontal wells, resulting in a lack of a theoretical basis for fracture spacing design. Therefore, it is necessary to study the stresses induced by multiple fractures in highly deviated wells. To reproduce the spatial distribution of multiple fractures in highly deviated wells and analyze the changes in induced stress more accurately, a three-dimensional numerical model of the fracture-induced stress field in highly deviated wells was established based on the finite element method and elasticity theory, which can simulate a fracture-induced stress field under different angles of inclination. The results indicate that the key to mutual exclusion or proximity of the two fractures is whether the fractures overlap in the plane parallel to the fracture height direction. Based on the analysis of the control variables, the first fracturing fracture height is the key factor affecting the induced stress, and the fracturing fracture height has slight effect on the induced stress. As the angle of inclination increases, the probability of the two fractures overlapping in space increases and the critical distance from the induced tensile stress to the induced tensile stress decreases. The influence of the fracture half-length, net pressure, and stress difference on the induced stress is related to whether the spatial projection of the two fractures overlaps. The research results provide a theoretical basis for the optimal design of staged fracturing in highly deviated wells.

ABSTRACT The increase in the amount of waste generated from construction and demolition (C&D) has raised concerns regarding landfill space and greenhouse gas emissions. One of the waste management practices that can remedy these issues is to convert the C&D wood waste into biofuel. The technical aspects, environmental benefits, and economic feasibility of such a practice may vary from one case to another and should be evaluated before implementation. In this study, techno-economic feasibility of establishing a biofuel production plant, which uses C&D wood waste delivered to the City of Vancouver (CoV)’s landfill in British Columbia, Canada is conducted. In addition, the GHG emission reduction of biofuel production compared with landfilling the C&D wood waste is investigated. According to the results, the average GHG emissions from landfilling all the waste is 24,350 tonnes of CO2 eq. while the emissions from biofuel production are 11,156 and 10,539 tonnes CO2 eq. for the biofuel production plant using diesel-based and electric-based equipment pieces, respectively. The GHG emission reductions are then monetized and included in the economic analysis. Results indicate that biofuel production is economically feasible only if the impacts of GHG emission reduction are considered. Moreover, sensitivity analysis and scenario analyses are performed on financial parameters, wood waste supply, biofuel demand, plant capacity, and plant ownership schemes. Based on these analyses, the biofuel selling price is the most impactful financial parameter on the outcome of economic feasibility. A 50% change in the biofuel selling price results in 42% and 45% change in NPV of the project for diesel-based and electric-based equipment, respectively. Furthermore, the ownership scheme, where CoV and a partner split the ownership and the partner operates the plant is the best option, with a net present value of more than $69 million.

ABSTRACT This study investigates the relationship between nanotechnological innovations, renewable energy consumption, economic growth, and ecological footprint for G7 countries within the framework of the Environmental Kuznets Curve (EKC) hypothesis. The study employs panel cointegration tests with structural breaks from 1990–2018. Nanotechnology is expected to reduce environmental degradation by increasing renewable energy consumption and energy saving. In this context, nanotechnological innovations are an essential tool for sustainable development. However, the literature also emphasizes that nanoparticle emissions from nanotechnology can negatively impact human and environmental health in the long term, and these need to be analyzed. In this context, this study is the first to empirically examine the relationship between nanotechnological innovations, renewable energy consumption, economic growth, and ecological footprint within the framework of the EKC hypothesis. The outcomes affirm that all variables are integrated with the long term. The results show that the EKC hypothesis is valid only in the USA. Nanotechnological innovations have a reducing effect on environmental degradation in the USA, whereas; they have an increasing impact on environmental degradation in Italy and the United Kingdom. Renewable energy consumption enhances environmental quality in Italy, Japan, the United Kingdom, and the USA. Based on these empirical findings, the government should pioneer to development of new the lowest nanoparticle-emitting nanotechnologies. And that way, it will be possible to encourage energy savings and renewable energy consumption more safely, and the effectiveness of sustainable development policies will increase.

ABSTRACT Energy consumption plays a crucial role in achieving the three pillars of the 2030 United Nations Sustainable Development Goals (SDGs). Moreover, the increasing impact of energy use in the development of North Africa motivates the authors to examine its direct impact on environmental degradation. Thus, the key objective of this investigation is to analyze the imperative impact of energy consumption on environmental degradation within the framework of urbanization and economic globalization. A fundamental hypothesis of the study includes that energy consumption and urbanization positively affect environmental degradation. The investigation employed the Cross-Sectional – Autoregressive Distributed Lag model and found that energy consumption significantly increases environmental degradation. However, economic globalization decreases environmental degradation. Moreover, urbanization showed inconsequential findings, but the study found that African countries hold the Environmental Kuznets Curve (EKC) hypothesis. The Dumitrescu-Hurlin causality model verifies the causality effect between energy consumption, economic globalization, urbanization, economic growth, and ecological footprints.

ABSTRACT As a fast-growing economy with over 1.35 billion people, India will be critical to achieving future climate targets. The country implemented many policies to limit its carbon emissions. To make targeted policies, it is imperative to evaluate the mutually opposing effects of fast development and climate policies on carbon emissions. We apply environmentally extended input-output analysis, and structural path and decomposition analysis to calculate key emission statistics and drivers of change in critical sectors and production paths. Results reveal that India is a net exporter of emissions and its production and consumption-based emissions have more than doubled between 2000 and 2016. Two sectors, ‘Electricity, gas, and water’ and ‘petroleum, chemical, and non-metallic mineral products,’ function as supplying sectors in most of the critical paths. Although improvements in emission intensity and production structure have helped in reducing emissions, household consumption and investments have increased them.

ABSTRACT Environmental degradation has become a severe concern across South Asia. Hence, it is imperative to model the macroeconomic determinants of environmental quality across this region. The traditional fossil fuel dependency of the major South Asian nations is alleged to have persistently deteriorated the quality of the environment across this region. Under such circumstances, it can be hypothesized that intra-regional trade within South Asia can facilitate renewable electricity trade to enhance environmental well-being. Accordingly, this study aims to evaluate the impacts of intra-regional trade integration, renewable energy transition, economic growth, and foreign direct investment inflows on the ecological footprints of selected South Asian economies. The econometric methods used in this study are suited for handling cross-sectionally dependent heterogeneous panel datasets. The overall results reveal that promoting intra-regional trade, stimulating renewable energy transition, expediting economic growth, and impeding inflows of dirty foreign direct investments are imperative for reducing the ecological footprint figures of the South Asian nations of concern. Besides, the results also verify the environmental Kuznets curve hypothesis for the South Asian panel as well as for Bangladesh, Sri Lanka, Nepal, and Bhutan but not for India and Pakistan. Moreover, the pollution haven hypothesis is also verified for both the panel and the individual South Asian countries. In line with these findings, several environmental welfare improvement-related policies are recommended.

ABSTRACT Promoting energy transformation is a major issue in achieving China’s carbon neutrality target. The changes in China’s energy consumption stemming from the policies related to this issue were simulated based on the energy policy simulation model. The results show the following. (1) Implementing related policies will significantly decrease total primary energy consumption, and non-fossil energy will be China’s main source of energy consumption by 2050. (2) The energy consumption corresponding to buildings, transportation, and industry will be electricity-led by 2050, and electricity will mainly be generated with non-fossil energy sources. (3) In 2030, China will reach a carbon peak, and non-fossil energy will account for 43% of the country’s primary energy consumption, comprising electrical (73%), solar (11%), wind (7%), hydro (7%) and biomass (2%) energy. (4) COVID-19 has had a short-term driving effect on this process, as it initially slowed down global economic cooperation, but it has had a hindering effect on the process in the long term.

ABSTRACT The paper analyzes the technical solutions, economic feasibility and institutional aspects of geothermal energy use in a district heating system by retrofitting wells on a mature oil field based on the case study. The objective is to describe institutional procedures for brine production from the mature oil field. The research methodology includes the well data and the condition of the existing oil infrastructure analysis, to evaluate the brine production possibility. The methodology also analyzes existing hydrocarbon contracts. Institutional steps to obtain a geothermal concession on the brownfields are proposed. The hypothesis assumes that, with the legislation change, a vertical distribution of concessions for simultaneous production of oil and brine is achievable. The conclusion brings the novelty of this paper as the provision of guidelines for the development of the projects and the start of the production of brine from a mature oil field for the investors and the legal authorities.
