Data Envelopment Analysis (DEA) is widely applied to evaluate technological efficiency in the energy sector, yet its results are often difficult to interpret, particularly when extended model specifications are used. This study investigates how alternative treatments of environmental conditions and undesirable outputs influence efficiency measurement in energy technologies. Four DEA specifications are compared: the classical CCR model, a model incorporating non-discretionary inputs (CCR-ND), a model including undesirable outputs (CCR-B), and a combined specification (CCR-ND-B). The empirical analysis is based on data describing coal gasification technologies and is supplemented with controlled hypothetical cases designed to isolate the effects of environmental parameters. The results show that incorporating non-discretionary inputs and undesirable outputs does not necessarily reduce efficiency scores but reshapes the geometry of the production possibility set and modifies the structure of benchmark technologies. The findings highlight the importance of careful classification of inputs and outputs and emphasize that DEA results should be interpreted in relation to the underlying modeling assumptions. Comparing alternative model specifications improves transparency and helps avoid treating DEA as a “black box”, supporting more informed efficiency assessment in energy technology analysis.

The widespread adoption of solar energy storage systems is transforming the global energy landscape, enabling more efficient use of renewable resources and enhancing energy resilience. The integration of residential batteries significantly enhances energy efficiency and sustainability by facilitating the storage of surplus renewable energy, providing reliable backup during power outages, and optimising energy consumption. This study explores the factors influencing end-user adoption of batteries, utilising the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) as a guiding framework to analyse adoption behaviours and determinants. This study employs a qualitative approach using semi-structured interviews with stakeholders divided into three categories: regulatory authorities, industry experts, and end-users. This study highlights key factors influencing battery adoption, such as energy independence, grid reliability, and environmental impact, while addressing challenges like regulatory inconsistencies and installer training. Study extends UTAUT2 to residential battery adoption, emphasising performance expectancy, facilitating conditions, and price value in decision-making and makes a methodological contribution by validating deeper qualitative insights into renewable technology adoption. The practical implications emphasise the need for designing targeted policies, such as subsidies and net metering, alongside developing user-centric systems that enhance affordability, usability, and consumer awareness to facilitate residential battery adoption.

Road transport is a significant contributor to greenhouse gas emissions within the European Union, with Poland showing one of the most pronounced increases since 1990. Motivated by gaps in national inventories (absence of vehicle-level mileage, limited fuel/age/spatial breakdowns, and scarce real-world hybrid performance data), we develop a novel vehicle-level integration method that links administrative vehicle records with scraped online car-sale listings via deterministic and probabilistic record linkage, imputes missing mileage, and applies age- and fuel type-adjusted emission multipliers to estimate per-vehicle emissions. The approach produces high-resolution breakdowns by fuel type, vehicle age and spatial units while explicitly accounting for hybrid vehicle behavior. This study introduces a novel methodology and analytical product that can be used to estimate emissions from the entire Polish passenger car fleet and monitor decarbonization progress. Applying this method to the Polish passenger-car fleet yields total 2024 passenger-car CO2 emissions of ≈41.4 million tonnes (our estimate aligns closely with independent national figures), with diesel, gasoline and LPG/CNG accounting for roughly 38%, 47% and 12% of CO2, respectively. We find that hybrids and EVs currently cut fleet emissions by ~2.6% (CO2), but their higher utilization magnifies their effect, while vehicle ageing increases total emissions by ~1.2% per year. These results demonstrate that integrating microdata substantially improves the monitoring of decarbonization progress. Full article

The rapid advancement of energy collection and storage systems (ECSSs) is fundamentally reshaping global energy markets and accelerating the transition toward low-carbon energy systems. This study provides a comprehensive assessment of the economic benefits and systemic effects of advanced ECSS technologies, including photovoltaic-thermal (PV/T) hybrid systems, advanced batteries, hydrogen-based storage, and thermal energy storage (TES). Through a mixed-methods approach combining techno-economic analysis, macroeconomic modeling, and policy review, we evaluate the cost trajectories, performance indicators, and deployment impacts of these technologies across major economies. The paper also introduces a novel economic-mathematical model to quantify the long-term macroeconomic benefits of large-scale ECSS deployment, including GDP growth, job creation, and import substitution effects. Our results indicate significant cost reductions for ECSS by 2050, with battery storage costs projected to fall below USD 50 per kilowatt-hour (kWh) and green hydrogen production reaching as low as USD 1.2 per kilogram. Large-scale ECSS deployment was found to reduce electricity costs by up to 12%, lower fossil fuel imports by up to 25%, and generate substantial GDP growth and job creation, particularly in regions with supportive policy frameworks. Comparative cross-country analysis highlighted regional differences in economic effects, with the European Union, China, and the United States demonstrating the highest economic gains from ECSS adoption. The study also identified key challenges, including high capital costs, material supply risks, and regulatory barriers, emphasizing the need for integrated policies to accelerate ECSS deployment. These findings provide valuable insights for policymakers, industry stakeholders, and researchers aiming to design effective strategies for enhancing energy security, economic resilience, and environmental sustainability through advanced energy storage technologies.
