The united states has thousands of kilometers of ocean coastline but tidal power plants are rare Which factor limits the development of tidal power?

The development of tidal power in the United States is limited primarily by high initial costs and the complex regulatory environment surrounding marine energy projects. Additionally, potential sites for tidal energy generation often face environmental concerns and opposition from local communities, which can hinder project approval. The technology is also still evolving, and there is a relative lack of infrastructure compared to other renewable energy sources like wind and solar.
