Accordingly, countries are strengthening their institutional frameworks for renewable energy to attract foreign direct investment (FDI) and accelerate renewable energy projects. This study investigated the effects of renewable energy policies on FDI and renewable energy consumption. This study analyzes 93 countries from the Belt and Road Initiative (BRI) from 2010 to 2021 using a two-step system Generalized Method of Moments (GMM), Fully Modified Ordinary Least Squares (FMOLS), and Dynamic Ordinary Least Squares (DOLS) estimators to address endogeneity and the Dumitrescu and Hurlin causality test for long-run cointegration. The results showed that renewable energy policies have contributed to increasing the consumption of energy from renewables. However, FDI has a negative effect on renewable energy consumption. Despite this, the relationship between renewable energy policies and FDI has played a significant role in fostering renewable energy consumption in BRI nations. Cointegration and long-run causality analyses revealed a promising long-term effect, suggesting that renewable energy policy and FDI positively affect renewable energy consumption. These results have important policy implications for advancing strategic projects through FDI by increasing energy infrastructure and renewable sources, thereby reducing greenhouse gas emissions and global climate change.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"246 ","pages":"Article 122915"},"PeriodicalIF":9.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The framework is trained using the data of an established PV site and then provides ultra-short-term PV forecasting for the newly constructed PV site. In the proposed framework, a temporal difference parallel Shifted window (Swin) Transformer-based structure is designed to capture the cloud motion details and extract the static spatial features. Then, a cross-attention structure is utilized to analyze the temporal features and predict the future PV generation. A variety of transfer strategies are designed to transfer the trained model to provide the PV forecasting at the new PV site. The training and transfer experiments are conducted with real-world sky images and PV generation datasets.

However, with the sharply increasing capacity, the PMSG’s shaft inevitably becomes stronger, yet there are few studies verifying its significance in the coupling between mechanical and electrical subsystems when investigating electrical oscillations in grid-connected PMSG-WTs systems. In this paper, an impedance model of PMSG-WTs, including both the mechanical shaft subsystem and the electrical subsystem, is established to specifically examine electrical oscillation issues. Based on this impedance model, the mechanism of electro-mechanical coupling on harmonic transfer within the PMSG-WTs is studied, revealing the non-negligible influence of the mechanical subsystem on the output impedance characteristic of PMSG-WTs. It is demonstrated that the mechanical shaft subsystem, with different rotor inertia and shaft damping coefficients, affects the harmonic transfer between mechanical and electrical subsystems, thereby impacting the output impedance characteristics of PMSG-WTs and system stability.

Fouling on the heating surfaces caused by condensation of salt vapor in the flue gas can also enhance the ash deposition by forming a viscous initial layer, which further captures fly ash. For multiple slagging prediction, an integrated model considering ash direct deposition, gaseous condensation and the subsequent ash capture has been proposed. Simulations of slagging in the superheater area were thus performed using ANSYS FLUENT with user define function (UDF), which were validated by sampling results of experimental study. The results show that the inertial impaction dominates the deposition of smaller particles (10–30 μm) with higher critical velocity, and the viscous capture behavior has obvious effect on larger particles of 50 μm and 80 μm. Condensation is inhibited with increasing temperature of deposited surface, while deposition efficiency increases due to a higher deposited surface viscosity. The proportion of viscous capture in the total deposition mass stays almost unchanged under different wall temperatures in three cases, with an average value of 26.9 %.

This oversight can lead to increased operating and maintenance costs, especially for offshore wind farms. To fill this technical gap, a multi-objective WFLO framework considering both fatigue damage and power generation is proposed. Via analytical wake models of wind speed and turbulence, the fatigue damage of each turbine can be rapidly evaluated accounting for both power production and wake turbulence. Typically, the Horns Rev wind farm is taken as a benchmark, and two indicators of fatigue damage, the maximum (<em>F</em>_max) and mean (<em>F</em>_{<em>mean</em>}) fatigue damage of all turbines, are considered in WFLO, respectively. The optimized layouts can achieve an increase in total power generation of over 2 % compared to the original layout, while reducing fatigue damage by about 1 %. Moreover, compared to single-objective WFLO focused solely on power generation, the multi-objective approach achieves a reduction of about 3.2 % in <em>F</em>_max, while maintaining a comparable power output level.

The geopolitics of the world is shifting from petro-economies (fossil-fuel based) to electro-economies (critical mineral based). The current study hypothesizes that transitioning from fossil fuel-based electricity generation to renewable energy (RE) sources is one of the most viable strategies for mitigating greenhouse gas (GHG) emissions and criteria pollutants, thereby protecting the environment from irreversible damage caused by climate change and worsening air quality, since RE technologies do not rely on combustion processes which substantially eliminate the release of harmful emissions. Therefore, the current study employed Life Cycle Assessment (LCA) approach to evaluate impact of energy transition in the electricity sector. The technical boundary is defined as a \"Gate-to-Gate\" focusing on the combustion phase, with a spatial boundary centered on Andhra Pradesh, India. This region utilizes energy from diverse electricity segments and further leverages Renewable Energy Share (RES) in the electricity mix. The functional unit selected for quantifying impacts was 1 kWh. The air emissions generated from 1 kWh of electricity generation were obtained from the Ecoinvent v3.3 database for different sources, including thermal power plants (Hard Coal and Natural Gas Combined Cycle), Wind turbines, Solar power, and Hydropower plant (Run-of-river, Pumped storage, and Reservoir type alpine region), present in the state. To test the hypothesis, midpoint impact indicators—Global Warming Potential, Photochemical Ozone Formation Potential, and Terrestrial Acidification Potential—were assessed. Endpoint evaluation further analyzed impacts on human health (measured in Disability-Adjusted Life Years) and ecosystems (terrestrial and freshwater species loss) to provide a comprehensive understanding of the environmental benefits of adopting RE technologies. The findings highlight that the environmental impacts associated with electricity generation have decreased, with Andhra Pradesh mitigating substantial emissions through an increased share of renewables in its electricity mix. This study validates the state's commitment to a clean energy transition and its alignment with Sustainable Development Goals (SDGs) related to clean energy and the environment. Additionally, it analyses several policy measures that are in place to encourage adoption of renewable energy and further highlights the drivers and barriers to their inclusion in the electricity mix.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"246 ","pages":"Article 122909"},"PeriodicalIF":9.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
