Abstract
With the implementation of the strategy of building maritime power, offshore renewable energy technology development is crucial for ensuring national energy security and enhancing economic efficiency. However, such efforts can also have ecological and environmental impacts that warrant significant attention. The responsible development of eco-friendly offshore renewable energy technologies and equipment is essential for actively promoting the growth of China’s marine economy and improving the marine ecological environment, which involves the structure design, material selection, deployment location, and so on. This study examines several key offshore renewable energy technologies, encompassing offshore wind power and photovoltaics, wave energy, and tidal energy and their effects on the ecological environment, comparing the research status in these fields between other countries and China and investigating the policies and plans implemented by various coastal provinces and cities in China. With the foreseeable rapid increase in the installed capacity of offshore renewable energy equipment, it is urgent to balance the relationship between offshore renewable energy technology and the marine ecological environment. Based on this analysis, the study offers recommendations for the future development of eco-friendly offshore renewable energy technologies, providing valuable insights for exploring environmentally sustainable offshore low-carbon energy solutions in China.
