The optimization process entails selecting the best mix of renewable energy sources and sizing components to obtain the best economic and technical performance. To handle the complexity of the optimization problem, the Nelder-Mead simplex search method is used, taking into account the stochastic nature of renewable energy generation and the nonlinear features of RES-based power plants. The simulation results show that the suggested hybrid system outperforms traditional diesel power generators in terms of economic viability and environmental sustainability. The system assures consistent power supply by using reserve energy devices such as batteries, thereby minimizing the intermittent nature of renewable sources.

The empirical analysis utilized the CS-ARDL model and focused on a sample comprising G7 economies. The robustness of analysis was examined by employing fully modified ordinary least square (FMOLS) technique. The estimated coefficients outline the significant negative impact of all main explanatory variables on fossil fuel energy and total energy and EGY in the long run and a significant negative impact on renewable energy in the short run. The findings further demonstrate the significant positive impact of financial development on fossil fuel energy and total energy and the significant negative relationship between financial development and renewable energy. Particularly, the analysis discloses the moderating role of financial development in the EPU-energy policy nexus. It is advised to policy officials that they should enhance the cooperation between the financial sector and the energy sector for the success of energy policy and for responding to the uncertain economic situation.

The analysis has uncovered the existence of two prominent coalitions: the progressive coalition is advocating for market liberalisation, while the conservative coalition is seeking to preserve the status quo and resist the adoption of the new electricity market model. The study concludes that powerful actors in the Electricity Supply Industry, although equipped with enormous economic resources and strong political ties, could not prevent the regulator from implementing comprehensive changes in the electricity sector. However, the conservative coalition has managed to negotiate for a phased implementation of the policy to ensure minimal disruption in the industry and to guarantee the security of the electricity supply in the long run.

Specifically, we use fixed effects regression analysis to investigate the responsiveness of EV list prices to changes in battery capacity over time, finding evidence that increases in battery capacity led to increases in EV prices that are substantially greater than estimated EV battery costs over our sample.

Compared to alternative hydroelectric turbines like Pelton, Francis, and Kaplan, the AST can provide a clean renewable energy source that is safer for fish and other aquatic species. While the AST is not universally superior to these other turbine technologies, it can offer unique advantages in certain low-head applications. Unlike Pelton, Francis, and Kaplan turbines, which typically require greater maintenance, debris collection systems, and continuous design improvements, the AST can operate effectively with fewer of these supporting requirements. To explore the potential of the AST in low-head hydropower generation, the present study conducted a comparative analysis of the AST against Pelton, Francis, Kaplan, bulb, and Vortex turbines. A meta-analysis was performed to synthesize data from various theoretical, experimental, and numerical studies, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, ensuring a rigorous and comprehensive review. The findings demonstrate that the AST can be a viable and advantageous option for power generation in sites with head heights below 10 m, generating between 4 kW and 140 kW of power with flow rates of 1–6 m³/s and efficiencies ranging from 72 % to 94 %. Additionally, this study provides an easy and quick method, along with analytical equations, for estimating the design parameters needed to predict screw power output. However, the suitability of the AST versus other turbines is highly dependent on the specific site characteristics and requirements. The analysis provides insights into the performance, maintenance needs, and environmental impacts of the AST compared to conventional hydroelectric turbines. These insights can inform decision-making on appropriate turbine selection for low-head hydropower projects.</p></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"55 ","pages":"Article 101514"},"PeriodicalIF":7.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2211467X24002232/pdfft?md5=8f3ebf9a8be0169c756102a9b0ac2a54&pid=1-s2.0-S2211467X24002232-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142128785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of this growth, GCC consumption-based carbon dioxide (CO<sub>2</sub>) emissions increased from 540.79 Metric tons of CO<sub>2</sub> equivalent (MtCO<sub>2</sub>) in 2003 to 1090.93 MtCO<sub>2</sub> in 2020. The assumptions and strategies that have driven energy production in the past are now being recast to achieve a more sustainable economic development. The aim of this study is to review and analyze ongoing energy transition strategies that characterize this change to identify challenges and opportunities for bolstering the effectiveness of current strategic orientations. The ensuing analysis shows that since COP26, GCC countries have been pursuing a transition away from carbon-based energy policies largely characterized by the adoption of solar PV with other emerging technologies including energy storage, carbon capture, and hydrogen generation and storage. While as of 2022 renewable energy adoption in the GCC only represented 0.15 % of global installed capacity, GCC countries are making strong efforts to achieve their declared 2030 energy targets that average about 26 % with peaks of 50 % in Saudi Arabia and 30 % in the UAE and Oman. With reference to solar energy, plans are afoot to add 42.1 GW of solar photovoltaics and concentrated solar power which will increase 8-fold the current installed renewable capacity (5.1 GW). At the same time, oil and gas production rates remain stable and fossil fuel subsidies have grown in the last few years. Also, there is a marked preference for the deployment of CCUS and utility-scale solar energy technology vs. distributed solar energy, energy efficiency and nature-based solutions. The pursuit of energy transition in the GCC will require increased efforts in the latter and other overlooked strategic endeavors to achieve a more balanced portfolio of sustainable energy solutions, with stronger emphasis on energy efficiency (as long as rebound effects are mitigated) and nature-based solutions. Increased efforts are also needed in promoting governance practices aimed to institutionalize regulatory frameworks, incentives, and cooperation activities that promote the reduction of fossil fuel subsidies and the transition away from fossil fuels.</p></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"55 ","pages":"Article 101512"},"PeriodicalIF":7.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2211467X24002219/pdfft?md5=22cbbf24c70827e524ff727cfaa57761&pid=1-s2.0-S2211467X24002219-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142122617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
