文摘The Chinese government promises to reach the carbon emission peak by 2030 and achieve the carbon neutrality by 2060.Renewable energy development is important for achieving this target.Local governments’behaviors and attitudes might be influenced by neighbors.Therefore,this study uses simultaneous autoregressive models(SAR)to examine the peer effects on renewable energy development across China’s provinces and explain the imbalanced renewable energy developments across regions in China.The results exemplified:①The peer effects exist in China and the endogenous interaction is the main cause.②The interaction between geographically adjacent provinces have greatest peer effects.③Both competition mechanism and learning mechanism induce the peer effects and the imbalanced development.This research introduces energy-related peer effects at the provincial level to reflect the preferences of governments and reveal the underlying mechanisms involved.It also provides suggestions to policy makers:①Select developed provinces as the frontrunner to promote the renewable energy development in neighboring areas.②Regional renewable energy development policies need to be considered.③Central government should consider adding“green growth indicators”into evaluation system to avoid the asymmetrical incentives policies between economic growth and environmental protection.
文摘Global climate change has created substantial difficulties in the areas of sustainability,development,and environmental conservation due to the widespread dependence on fossil fuels for energy production.Nevertheless,the promotion of renewable energy programs has the potential to significantly expedite endeavors aimed at tackling climate change.Thus,it is essential to conduct a thorough analysis that considers the financial aspects to fully understand the main hurdles that are preventing the advancement of renewable energy initiatives.Italy is a leading country in the worldwide deployment of renewable energy.The objective of this research is to assess the impact of financial growth,economic progress,and energy expenses on Italy’s adoption of renewable energy sources.By employing the Auto-Regressive Distributed Lag(ARDL)technique,we analyzed annual data spanning from1990 to 2022.Findings revealed that a 1%increase in financial and economic development would boost renewable energy consumption in the long run by 0.29%and 0.48%,respectively.Instead,a 1%increase in energy prices might reduce consumption of renewable energy by 0.05%in the long run.This study’s primary significance lies in furnishing actionable strategies for Italy to augment green finance for renewable energy,fostering sustained social and economic progress.Moreover,the analytical insights gleaned from this research offer valuable insights for energy-importing nations worldwide.

文摘With the development of integrated power and gas distribution systems(IPGS)incorporating renewable energy sources(RESs),coordinating the restoration processes of the power distribution system(PS)and the gas distribution system(GS)by utilizing the benefits of RESs enhances service restoration.In this context,this paper proposes a coordinated service restoration framework that considers the uncertainty in RESs and the bi-directional restoration interactions between the PS and GS.Additionally,a coordinated service restoration model is developed considering the two systems’interdependency and the GS’s dynamic characteristics.The objective is to maximize the system resilience index while adhering to operational,dynamic,restoration logic,and interdependency constraints.A method for managing uncertainties in RES output is employed,and convexification techniques are applied to address the nonlinear constraints arising from the physical laws of the IPGS,thereby reducing solution complexity.As a result,the service restoration optimization problem of the IPGS can be formulated as a computationally tractable mixed-integer second-order cone programming problem.The effectiveness and superiority of the proposed framework are demonstrated through numerical simulations conducted on the interdependent IEEE 13-bus PS and 9-node GS.The comparative results show that the proposed framework improves the system resilience index by at least 65.07%compared to traditional methods.
