The Current Status of Global Energy Crisis and the Development of Novel Marine Energy Sources

Abstract

International geopolitical conflicts have caused international oil and gas market switching, which has caused a huge impact on the global oil and gas supply chain and changed the world's energy supply pattern. International fossil fuel prices are likely to remain high, giving the United States more say in energy markets. This paper introduces that this reality has triggered the consideration of energy security and increased the attention of countries to new energy. The ocean is rich in renewable energy, including tidal energy, wave energy, ocean current energy (tidal current energy), offshore wind energy, and so on. This paper points out that these energy sources are abundant, clean, and renewable, and are regarded as one of the most promising alternative energy sources at present. This paper discusses the importance of tidal energy as a renewable energy source due to its clean and stable properties. Although tidal energy has the advantages of high stability and good predictability, its high cost, long construction cycle, and potential ecological impact limit its commercialization. Finally, the development prospect of tidal energy in China is prospected. It is concluded that China is rich in tidal energy resources and has considerable development potential with the support of policies and funds.
