Large-Scale Renewable Energy Development in Coastal Zones and Wetland Conservation: a Review of Status, Scientific Issues, and Challenges 

China has witnessed a substantial surge in the advancement of renewable energy technologies deployed across tidal flat ecosystems. Due to the favorable attributes of low transmission costs and abundant resources, numerous photovoltaic and wind power joint development areas have been established or are planning for deployment adjacent to coastal wetlands. However, their potential impacts on the dynamic environment of coastal wetlands, wetland vegetation and geomorphic evolution are still unclear. In this paper, we focus on the Yellow River Delta. The current research status of the coordination and gain mechanisms between the large-scale development field of renewable energy converters in the tidal flats and the wetland is reviewed. Related  scientific issues and challenges include but are not limited to the following four aspects are analyzed : 1) The response mechanisms and evolutionary patterns of marine aerodynamic elements to climate change; 2) New technologies for erosion protection in marine engineering structures with adaptive spatial layout; 3) The dynamics of far-field wetland environments, wetland vegetation, and geomorphic evolution under different types of marine engineering structures and their array configurations; 4) A potential model for the integrated utilization of renewable energy in tidal flats, which considers wetland protection, restoration, and safe operation. The outcomes will contribute to identifying the correct direction of the coordinated enhancement of renewable energy utilization in shallow seas and coastal areas, focusing on mechanisms, analytical tools, and protective technologies to ensure synergy with environmental protection efforts.
