The G7 nations is a major global consumers of natural resources and energy. These nations are confronted with substantial obstacles in their pursuit of sustainable growth through energy transition, while upholding their status as global economic leaders. As a result, this current study conducted an aggregated and disintegrating analysis on the heterogeneous role of green energy innovation on energy transition in G7 nations. Green energy innovation was disintegrated into hydro, solar and wind energy. Moreover, the heterogeneous effects of green innovation in solar, hydro and wind on energy transition was investigated, an analysis that has not been previously examined. For the econometric estimation, we adopted the Quantile-on-Quantile Regression (QQR) and the quantile causality method. The results of the QQR indicates that the positive role of green energy innovation on energy transition in all of the G7 nations. However, this positive role is more dominant in five G7 nations, namely Italy, Germany, Japan, the UK and the USA. Additionally, the result also highlights that the connection between green energy innovation and energy transition is differs across the various quantiles for different nations. Moreover, the quantile causality analysis indicates that green energy innovation has the potential to predict future values in energy transition within the G7 nations. The study emphasizes various policy considerations for promoting energy transition through green energy innovation in G7 nation, which help realizing sustainable development. [ABSTRACT FROM AUTHOR]

There is no doubt that the transition towards renewable energies is generating many changes on different continents, some with greater impacts than others, but the development that has occurred is recognized and widely accepted. The progress has been significant but it is necessary to analyze the roadmaps that have been proposed so far at the island level so that decision makers have sufficient tools to commit the much-needed economic resources to transform their energy systems into 100% renewable ones. These approaches are not simple and the hard work of the authors who have disseminated their research is recognized. The roadmaps are planned based on the energy potential available in the territories and the future energy demand. Within countries, it is important to increase the economic resources to allocate to investments in environmentally friendly renewable energies. In this review of 100% renewable smart systems on islands, the situation of the American continent, its challenges and its long-term approaches in the different geographical areas facing 2050 are analyzed. This article shows that research into the design of 100% renewable energy systems in scientific articles is fairly new but has gained more and more attention in recent years. In total, 175 articles published since 2002 were identified and analyzed. Many of these articles have a predominant focus on the electricity sector. As a general result, it has been determined that although there has been significant progress towards an orderly energy transition, this has not been consistent with the international agreements signed since the Paris Summit, which is a real challenge in complying with the new commitment of the COP28 of Dubai in tripling the participation of renewables.

The proliferation of green industrial policy strategies around the world is taking place within a broader global context of a turn toward deglobalization and the pursuit of national self-sufficiency. The political economy of domestic renewable energy support and the basic principles of global trade regimes are in direct conflict, with direct implications for nations' abilities to transition to low-carbon economies. Many are calling for decoupling clean energy supply chains from China, yet such responses could slow the global clean energy transition, increasing the cost of deployment in developing countries.

The conversion of methane to value‐added chemicals by traditional reforming processes suffers from intensive energy consumption due to its particularly strong C─H bonds. Thus, it is urgent to optimize the driving force structure for methane conversion by accelerating the integration of sustainable energy. In this review, the advances in sustainable energy‐driven methane conversion are systematically summarized to provide a scientific understanding of methane conversion in operation/storage concepts, reactor design, technological maturity, system optimization, and remaining issues. Furthermore, the essence, economic evaluations, energy balance, and social impacts of methane conversion driven by sustainable energy are carefully discussed, paving a path for the future course of research and development. Diversifying the energy mix can play an important role in the future of sustainable energy‐driven methane conversion industries, being used as a crucial step for the transition to sustainable energy, especially the combination of solar/nuclear energy with fossil fuels to produce value‐added chemicals. Additionally, this review intends to bridge the studies of methane conversion and sustainable energy‐driven development, with the ultimate goal of offering a robust framework to understand the current status of sustainable energy‐driven methane conversion and provide guidance for the design of sustainable solutions for a greener future.

The high-altitude Central Asian communities (mainly from rural Tajikistan and Kyrgyzstan) face a high degree of energy complexity. The thematic knowledge clearly outlines that these communities hold special energy identity (information about energy requirements, energy consumption, classification of the building, energy resources, energy services, and challenges) and at the same time, energy poverty ironically exists. To mitigate energy poverty, there is an immediate need for sustainable energy transition through special energy planning. Though, the limited information about the energy identity of these communities restricts the energy transition process. The main aim of the paper was to outline the special and comparative energy profile of high-altitude Central Asian rural communities. To demonstrate the special energy profile, a novel correlative approach was developed which synthesises the information about energy context (current energy situation and critical issues), energy resources (available sustainable and non-sustainable energy and its usage) and energy services (available energy services to meet the energy need) by considering local boundary conditions. These various parameters were studied based on the extensive literature review, the author's interview with local people and the previous work of the authors. There is a large gap in the literature regarding energy information about high-altitude Central Asian communities. Based on the correlative approach, the presented article was the first attempt to develop a novel framework to interpret the energy identity of high-altitude Central Asian communities and thus contribute to knowledge. The derived special energy identity will serve as a profound base to develop an energy planning more effectively. The derived results categorised the spatial energy situation at the roof of the world. Even though access to electricity, the high-altitude Central Asian rural population suffers from unique and complex energy challenges articulated in the presented article. Energy is a costly and critical task for the local population. To resolve this issue, sustainable energy transition is an essential element for these settlements which ensures sustainable communities from the long-term perspective. This can be achieved by spatial energy planning for high-altitude communities (i.e. implementation of energy efficiency measures in combination with an energy supply system on a community level). • The high-altitude rural communities in Central Asia face unique energy challenges as significant energy required for heating due to old and uninsulated buildings, extreme cold climate and high-altitude terrain • A novel correlative approach was established to develop energy identity of communities situated at roof of the world • Guide for energy identity of high-altitude rural communities of Kyrgyzstan and Tajikistan is developed • This study demonstrates immedaite need of sustainable energy transition at roof of the world • The research suggests that building energy efficiency is a key parameter to achieve the complex sustainable energy transition at roof of the World.

We study effects of energy market uncertainty shocks on energy transition on the 28 European Union countries from 1990 to 2015 using annual frequency data. We assess the effects of oil price as well as the energy market supply, demand, and residual price shocks using a time-varying parameter panel data stochastic volatility model. We show the importance of reducing energy market uncertainty for the success of a clean energy transition in Europe as uncertainties have strong time-varying effects on the transition from fossil fuels to renewable energy. The oil price and residual energy price uncertainties are the key factors encouraging renewable energy transition that reduces the vulnerability of economies to energy shocks. Energy supply shocks affect the transition negatively while the demand shocks work similarly to residual energy prices shocks, requiring a robust energy base that is less volatile. The paper also discusses policy recommendations. [ABSTRACT FROM AUTHOR]
