In this study, using China's two national energy-saving initiatives as prototypes, we introduce a two-player evolutionary game model to analyze both the direct and indirect impacts of these regulations. This model deconstructs competitive dynamics into production competition and green innovation competition, and identifies key conditions under which regulations can achieve dual goals, highlighting a strong convergence effect and an appropriate regulatory intensity that slightly below the threshold. Through heterogeneity and sensitivity analyses, our findings suggest that targeting enterprises with high energy efficiency, industries with significant market concentration, enhancing innovation intention before regulation, and amplifying the market benefits of green innovation effectively promote green innovation.

We also use Sorted Effects Analysis (SEA) to explore differences within the population and identify vulnerable groups most affected by the health risks of unclean fuel use. The SEA results reveal that the health effects of polluting fuels are not uniform, and there is some evidence that housing quality—such as roofing and walls—moderates the relationship between polluting fuels and health outcomes.

The entropy method guarantees an objective weight allocation based on data variability, whereas TOPSIS enables a transparent classification of countries by assessing their proximity to an ideal ESG-performance profile. The methodological stability of the approach is underscored by the sensitivity analysis, which confirms the robustness of the rankings under differing weight scenarios. We have discovered that the governance dimension, particularly internal auditing, and environmental metrics, such as resource utilization, substantially contribute to the enhancement of policy energy efficiency. In contrast, social dimensions have a marginal impact, indicating the necessity of more comprehensive strategies.

This paper investigates a critical dimension of energy security by constructing a Green Total Factor Energy Efficiency (GTFEE) index, derived from the super-efficiency SBM model, to examine the impact of geopolitical risk on energy efficiency across 43 countries from 1998 to 2022. Employing instrumental variable quantile regression, the results show a positive relationship between GPR and GTFEE, with the effect becoming stronger at higher GTFEE quantiles. This impact is more pronounced in developing economies with mid-to-low income levels than in high-income developed nations. Furthermore, using a regression discontinuity design, the study finds that events such as military conflicts, international tensions, and Public Health Emergencies of International Concern (PHEIC) significantly increase GTFEE. Complementary analysis based on the World Energy Trilemma Index further indicates that geopolitical risks enhance energy security and environmental sustainability.

This work aims to tackle the increased uptake of CES concepts by framing the economic incentive fundamentals for the operation of ECs with central community storage as well as stationary and mobile swarm storage. Thereby, non-strategic behaviour as well as strategic operation procedures are investigated. Our analysis shows that variable retail energy prices cause a range of situations with different economic incentives for individual EC entities (e.g. prosumers, consumers, CES). We learn that economic operation incentives do not necessarily align with system- or grid-friendly behaviour, and can even lead to ’unnatural’ behaviour of ECs, such as minimising self-consumption instead of maximising it. This shows the necessity to consider a much more complex incentive structure at the community level in the future, addressing both, the possibilities as well as drawbacks and gaps identified within this study. We conclude that a range of legislative amendments will be inevitable, both at EU and national level, to foster a basis for CES integration that aligns economic goals of ECs with the needs of the energy system and the electricity grid, and avoids contradictory or unnatural behavioural incentives.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"151 ","pages":"Article 108896"},"PeriodicalIF":14.2,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings indicate that although ETSs have the potential to drive decarbonization, their impacts vary substantially across the world. A key finding is that ETS impacts are significantly shaped by an economy's structural dependence on natural resource rents: greater dependence on natural resource rents weakens the effect of ETS introduction on renewable energy adoption. We also find that ETSs are effective in reducing carbon intensity more in developing economies than in developed economies. Additionally, nationwide ETSs are more effective than partial rollouts. Further, beyond the extensive margin analysis (effect of ETS introduction), the intensive margin analysis reveals that temporal increases in weighted-average ETS carbon price amplify emissions reduction and renewable energy adoption.

CTS and RPS share similar objectives due to the overlap of industry and sector. Nevertheless, it remains unclear whether their combined implementation can effectively foster renewable energy growth and reduce carbon emissions, given the complex interactions among electricity market participants. Our research develops a decision-making model for the electricity market that captures the strategic interaction between the supply side and demand side, as well as price competition between heterogeneous power generators. Four policy mechanism scenarios are constructed, and equilibrium outcomes are derived through backward induction. Building on the above model, we evaluate the synergistic effects of policy combinations, primarily the impact on electricity prices, renewable energy consumption, carbon emission reduction and social welfare. We further examine the effectiveness of RPS penalties and carbon trading regulations from the perspective of regulators. The findings suggest that the joint implementation of CTS and RPS fails to generate significant synergistic effects on carbon reduction or social welfare under current market conditions in China. When consumers' guilt coefficient for using coal-fired electricity and the carbon price are low, while the RPS target is high, the combination yields clear improvements in both outcomes.
