    Energy economic expansion with production and consumption in BRICS countries
    (Elsevier Ltd, 2022-11-18) Hasan M
    Global energy demand for energy consumption is increasing day by day, and it seems complicated for most countries to meet energy demand with total energy production. In this regard, this study investigates the comparative impact of energy production and consumption on economic growth in the BRICS countries. This study conducts panel data modelling, more specifically, the fixed-effects model, random-effects, and panel FMOLS model, to find the impact of energy production and consumption on economic growth in the BRICS countries. This study finds that energy production and consumption significantly impact the economic development of the BRICS countries. More specifically, dry natural gas production and consumption, electricity generation and consumption, biofuel production, petroleum production, capital formation, and trade openness positively impact on economic growth, while coal production significantly and negatively impacts on economic growth. This research is of great significance to the economic integration of the BRICS economies.

    Sustainable biofuel economy: A mapping through bibliometric research
    (Elsevier B.V., 2023-06-15) Hasan M; Abedin MZ; Amin MB; Nekmahmud M; Oláh J
    Biofuels have received a lot of attention as an important source of renewable energy, with number of economic impacts. This study aims to investigate the economic potential of biofuels and then extract core aspects of how biofuels relate to a sustainable economy in order to achieve a sustainable biofuel economy. This study conducts a bibliometric analysis of publications about biofuel economic research covering 2001 to 2022 experimenting with multiple bibliometric tools, such as R Studio, Biblioshiny, and VOSviewer. Findings show that research on biofuels and biofuel production growth are positively correlated. From the analyzed publications, The United States, India, China, and Europe are the largest biofuel markets, with the USA taking the lead in publishing scientific papers, engaging country collaboration on biofuel, and has the highest social impact. Findings also show that the United Kingdom, the Netherlands, Germany, France, Sweden, and Spain are more inclined to develop sustainable biofuel economies and energy than other European countries. It also indicates that sustainable biofuel economies are still far behind those of less developed and developing countries. Besides, this study finds that biofuel linked to sustainable economy with poverty reduction, agriculture development, renewable energy production, economic growth, climate change policy, environmental protection, carbon emission reduction, green-house gas emission, land use policy, technological innovations, and development. The findings of this bibliometric research are presented using different clusters, mapping, and statistics. The discussion of this study affirms the good and effective policies for a sustainable biofuel economy.

    Common volatility in clean energy stocks
    (Elsevier B V, 2025-08-01) Pham L; Pham S; Do H; Bissoondoyal-Bheenick E; Brooks R
    This study investigates common volatility (COVOL) within the clean energy sector, motivated by the sector's growing importance and its susceptibility to external shocks. For this purpose, we use the COVOL measure developed by Engle and Campos-Martins (2023) to explore sector-wide and sub-sector common volatility, in a range of sub-sectors including renewable energy, energy storage, energy conversion, power conservation, and greener utilities. Our analysis highlights the major events that significantly impact the volatility of clean energy stocks. These include global economic disruptions, geopolitical tension, policy changes and climate-related events. Other key findings reveal the heterogeneous association of sub-sectors’ COVOL to different economic and financial factors, alongside superior explanatory power of COVOL on clean energy risk and return compared to alternative news-based uncertainty measures. These insights emphasize the importance for investors to integrate thorough risk management strategies and for policymakers to create a stable, supportive environment for the clean energy market. The study's implications extend to enhancing sector resilience and informing strategic investment and policy decisions, contributing to the sustainable growth of clean energy amidst global economic and environmental uncertainties.

    “Stretch and transform” for energy justice: Indigenous advocacy for institutional transformative change of electricity in British Columbia, Canada
    (Elsevier Ltd, 2025-07) Hoicka CE; Regier A; Berka AL; Chitsaz S; Klym K
    Transformative energy justice addresses root causes and legacies of inequality, centers voices and world views of historically excluded communities in the problem definition, decision making and transition processes. This study offers insights from a unique case of meso-level collective action by First Nations in British Columbia (BC), Canada, aimed at transformative electricity institutional change. We collate regulatory and advocacy text to characterise the range of proposed First Nation Power Authority models and their placement along a continuum of conformative to transformative energy justice. Interviews with knowledge holders from 14 First Nations offer insight into motivations behind transformative change and how it is shaped by historical injustice alongside practical community objectives around energy security, resilience, and community development. First Nations narratives of electricity transformation are aligned with the United Nations Declaration of the Rights of Indigenous People (UNDRIP) and with goals of self-determination and incorporate relational and regional approaches. These findings validate theoretical frameworks of transformational energy justice (Avelino et al., 2024; Elmallah et al., 2022). Much of the groundwork has been laid by the collective and the regulator, while new legislation has opened a window of opportunity to increase Indigenous participation and control in the electricity sector.

    Volatility spillovers and carbon price in the Nordic wholesale electricity markets
    (Elsevier B V, 2024-06) Lyu C; Do HX; Nepal R; Jamasb T
    This paper investigates price volatility and spillovers in the Nordic electricity wholesale markets. We use the Time-Varying Parameter Vector Autoregressive (TVP-VAR), Rolling Window-based VAR (RW-VAR), and high dimensional VAR with common factors (VAR-CF) methods and analyze the integration dynamics among these markets and impact of carbon prices on volatility spillovers. We use 107,352 hourly price data from January 2010 to March 2022. The novelty of this research is four-fold. First, we adopt a connectedness approach to explore volatility interactions among the four Nordic markets, contributing to the scarce literature on volatility in this market. Second, we segment the Norwegian market into southern and northern regions, revealing differences in volatility spillover patterns. Third, we investigate the effect of carbon prices on volatility spillovers and market dynamics. Last, we show significant contribution of covariances to interdependence among markets. We find significant connectedness between the Nordic markets, with an average Total Connectedness Index of between 50% (with a system of variance) and 90% (with a system of both variance and covariance). Sweden is the sole net volatility spillover transmitter, while Denmark experiences the largest shocks from the system. We further find that carbon prices exert a 5% significant impact on the volatility spillover index.
