Economic development brings along strong energy demand. Northeast Asia is one of the regions with the most potential for further energy development in the world. Due to the complex geopolitical dilemma, barriers haven't been eliminated in energy trade and investment; therefore, there is more...

This study is to build a causality model to implement energy security strategies (ESSs) in approaching a world-regions comparison. This study contributes to ESSs by indicating a set of valid attributes and those attributes are interrelationships in nature. There is major global interest in ESSs...

The era of energy interdependencies between Russia and the European Union (EU) is at an end. This paper advances a nuanced accounting of energy security based on energy sovereignty and energy solidarity. Energy solidarity requires a pooling of energy sovereignty based on values. A historical...

The energy supply sector, encompassing vital components such as generation, transmission, and distribution, holds a pivotal role in satisfying the energy demands of modern society. Its intricate web of technologies and infrastructure ensures the reliable provision of electricity from diverse...

Sub-Saharan Africa (SSA) is experiencing rapid economic growth and rising demand for energy, accompanied by significant low energy access and sustainability challenges. Globally, to address similar issues and unlock a region's energy potential, regional integrated energy systems have gained...

Bangladesh launched the Vision 2021 initiative to reach the status of a middle-income country and provide universal access to power. This gave an impetus to a significant rise in installed generation capacity, with the most positive developments seen through the Seventh Five-Year Plan and...

Currency depreciation poses challenges to long-term sustainable energy planning, particularly in the context of developing nations and cities. Yet, energy system models typically fail to assess the impacts of currency depreciation on sustainability strategies. This study employs a cost...

Energy system models provide us with scenarios for the future energy system, supporting our understanding of the impact of societal changes and adopted policies. To front-load the EU'Fit for 55' package for 2030 and targets of replacing imported natural gas with renewable electricity, the Nordic...

Through the long-distance transmission of electric energy, global interconnected power grids have become promising for the decarbonization of the power systems nowadays. However, the implementation of an extremely large-scale system may be controversial because practical examples are rare. In...

The energy transition is leading to profound changes in all parts of the energy system, but the reduction of fossil fuels in the heating sector is a major challenge for the energy sector. The changing heat-generating structure also affects its supply infrastructures. The impact on the existing...
