As the G20 produces more than 80% of global emissions, assessing the effectiveness of Emissions Trading Systems (ETS) in this sector is crucial. This study examines the causal impact of ETS adoption on power-sector CO₂ emissions in G20 economies from 1990 to 2023 using multi-period staggered difference-in-differences (DID) models. ETS is modeled as a policy treatment variable, with macroeconomic controls and Environmental Kuznets Curve (EKC) terms included. Robustness is verified through placebo tests, heterogeneity checks, and dynamic group-time average treatment effects (ATTs). Results show that ETS implementation significantly reduces power-sector emissions, with effects robust across model specifications and sub-samples. More importantly, our cross-national comparative analysis reveals divergent outcomes: while dynamic analysis confirms that ETS effectiveness strengthens over time in most economies, this trend is notably absent in key exceptions such as China and Mexico, where emissions continue to rise. Overall, while ETS is an effective market-based instrument, its success is highly conditional on national contexts and structural factors.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"65 ","pages":"Article 102253"},"PeriodicalIF":7.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147803139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the residential sector accounts for almost half of the total electricity demand, increasing the residential electricity efficiency is critical. This research is based on stochastic frontier analysis on balanced panel data for eleven electricity distribution regions for Pakistan during 2004 to 2023. The True Fixed Effects Model (TFEM) provides an estimate of the average residential electricity efficiency score at 0.854, which means that consumption is 14.6 percent more than the statistically estimated minimum feasible demand. The model by Kumbhakar and Heshmati (1995) further breaks down inefficiency into transient and persistent inefficiency. Average transient efficiency is 0.947 and average persistent efficiency is 0.470, so long-run structural inefficiency has dominated short-run behavioral inefficiency. Persistent efficiency is especially low in FATA, Frontier and Karachi where structural constraints are pronounced. Distribution losses have a negative elasticity of about −0.140 which reflects the system inefficiencies and recording weaknesses Efficiency estimates are statistical benchmarks with respect to a minimum demand frontier and should be considered as upper limits of reductions in demand and not engineering limits.

Green technologies consistently reduce emissions and promote energy transition across all quantiles. Natural resources significantly hinder energy transition (−0.3969 to −0.4751) but show no direct significant impact on CO₂ emissions, challenging conventional \"resource curse\" assumptions. Population growth impedes transition only in low-transition countries.

Notably, while overall electricity demand in 2035 is projected to rise from the pre-war level, this study suggests no growth is needed in hard coal or nuclear power capacities across all regions. Instead, innovations such as currently underutilized bioenergy and wind power, as well as modern gas capacities can replace hard coal. Along with transmission and interconnection capacities, electricity storage and especially pumped hydropower storage need to expand to balance renewable and nuclear power generation. The findings and the robustness of the identified regional clusters is further validated in a sensitivity analysis. The estimation of various environmental, economic, and social impacts across subnational regions indicates that mere cost efficiency should not solely dictate policy: a holistic approach is necessary to foster regional equity and robust green transition.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"65 ","pages":"Article 102250"},"PeriodicalIF":7.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147858555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To align with the objectives of COP28 and SDG13, this study examines the factors that influence environmental sustainability from both supply-side and demand-side perspectives. The current study explores the relationship between renewable power production, digitalization, financial modernization, natural resource rent, and the effectiveness of government on carbon dioxide emissions in selected South Asian economies spanning 1998 to 2023. Using the Method of Moments Quantile Regression (MMQR), our findings indicate that dependence on natural resources, digitalization, and financial modernization are substantial factors in carbon dioxide emissions. However, the effectiveness of the government and the production of renewable electricity emerge as mitigating factors, thereby reducing environmental degradation. To reduce carbon emissions in South Asian economies, Policymakers should implement regulations and incentives to ensure that financial development and digitalization support environmental sustainability. They must increase investment in renewable energy and diversify their economies to reduce dependence on non-renewables, while directing natural resource revenues toward green technology R&amp;D.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"64 ","pages":"Article 102052"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results reveal climate-specific patterns: cold and arid regions most consistently benefit from insulation, thermal screens, phase-change storage, and solar–thermal-assisted heating; temperate and tropical climates increasingly adopt advanced control, including model predictive control and data-driven/learning-based controllers, to coordinate multi-variable microclimate-energy trade-offs. Renewable integration is expanding across zones, yet harmonized techno-economic and life-cycle assessments remain limited.

This article explores the socio-economic impacts of transforming a city neighbourhood into a carbon-neutral district in Stavanger, Norway, focusing on how business owners, political party leaders, leaders of civil society organizations, and custodians of history and heritage perceive the development of PEDs. Drawing on interviews with key stakeholders in Stavanger, this paper argues that while economic resources, capabilities, infrastructure, and technology are essential for driving energy transition efforts, it is equally important to integrate bottom-up community perspectives into PED planning.

This study examines the mechanisms, effectiveness, and stakeholder responses characterizing this policy evolution through a focused empirical analysis grounded in industrial policy theory and directed technical change literature. Employing a case study methodology, we analyze 127 policy documents (2015-2024) and conduct semi-structured interviews with 23 stakeholders across government agencies, industry organizations, and research institutions in Jilin Province. Thematic analysis reveals a systematic three-phase transition: selective phase (2009-2016) characterized by direct subsidies and technology picking; transition phase (2017-2020) introducing market-based mechanisms; and functional phase (2021-present) emphasizing infrastructure development and competitive R&amp;D funding. Market outcomes demonstrate functional policy effectiveness: NEV sales increased from 1.37 million units (2020) to 9.5 million units (2024), market competition intensified with manufacturers rising from 15 to over 300, patent applications increased 125%, and exports grew 2125%. However, stakeholder interviews reveal implementation challenges including regional coordination difficulties and institutional capacity constraints. The findings contribute to industrial policy theory by demonstrating that functional approaches can address market coordination failures in emerging green technology sectors while avoiding distortions associated with selective interventions, though effectiveness depends critically on institutional capacity and gradual transition management. Unlike previous studies that focus on aggregate outcomes or specific instruments, this research systematically connects policy transition mechanisms to stakeholder responses and market outcomes, advancing understanding of how government intervention can enhance rather than replace market forces in green technology development. The study provides evidence-based guidance for policymakers designing market-oriented industrial policies for sustainability transitions.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"64 ","pages":"Article 102101"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147399050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses the economic optimization challenge of off-grid hydrogen energy systems serving remote communities in Qinghai, Tibet, Inner Mongolia, and Xinjiang, where diesel generation costs exceed $0.30/kWh including transportation. We develop an economic-centered energy management framework integrating solar photovoltaics with hydrogen production, storage, and fuel cell generation to minimize total system costs while ensuring reliable energy supply.The research presents a techno-economic optimization model analyzing capital expenditure, operational costs, component replacement schedules, and system degradation economics across 20-year project lifetimes. A predictive energy management strategy employing machine learning forecasting and dynamic control algorithms optimizes production-consumption patterns to reduce equipment cycling costs and maximize revenue from energy sales. Economic feasibility analysis under Chinese market conditions reveals levelized cost of energy (LCOE) of $0.19–0.24/kWh for hydrogen-integrated systems, achieving cost parity with diesel alternatives while eliminating fuel supply chain vulnerabilities.Cost-benefit analysis demonstrates: (1) optimized energy management reduces annual equipment replacement costs by $4800 through extended component lifespans, (2) thermal energy recovery decreases hydrogen production costs by 13.2%, saving $6400 annually in operational expenditures, (3) integrated system efficiency improvements lower total energy costs by 18.7% compared to conventional control strategies, and (4) net present value reaches $58,000 over project lifetime with internal rate of return of 11.3% under current subsidy frameworks. This study suggests establishing hydrogen equipment subsidies at 35–45% of capital costs for remote installations, implementing differentiated feed-in tariffs ($0.10–0.15/kWh) for off-grid renewable hydrogen systems, creating low-interest financing mechanisms (2–3% annual rate) for rural energy cooperatives, and developing technical certification standards for economic energy management systems. These interventions can accelerate deployment of 500–800 MW hydrogen capacity in underserved regions by 2030, benefiting 2.3 million rural residents while reducing diesel consumption by 180,000 tons annually.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"64 ","pages":"Article 102078"},"PeriodicalIF":7.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147399245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
