Tidal and wave energy can have environmental impacts such as disturbance to marine ecosystems, changes in sediment transport, and potential harm to marine species due to collisions with turbines or disruption of habitats. However, compared to traditional fossil fuel sources, tidal and wave energy have lower greenhouse gas emissions and can help reduce reliance on polluting energy sources. Proper site selection and project design can help minimize negative environmental impacts.
One drawback of tidal energy is its limited availability in certain locations with strong tidal currents. Additionally, the high capital costs associated with building and maintaining tidal energy facilities can be a disadvantage. Finally, potential environmental impacts on marine ecosystems and wildlife are also a concern for tidal energy development.
Tidal energy can face opposition due to the potential environmental impacts on marine ecosystems, disruption of tidal patterns, and concerns over the high installation and maintenance costs of tidal energy infrastructure. Additionally, community resistance may arise from the visual impact of tidal energy devices on coastlines and navigation routes.
Tidal energy itself cannot be conserved, as it is a renewable resource that replenishes naturally with the ebb and flow of tides. However, the technology used to capture and convert tidal energy into electricity can be improved to be more efficient and sustainable. Efforts to minimize environmental impacts and maximize energy output from tidal sources can help in utilizing this renewable energy source effectively.
Some limitations of tidal energy include high installation and maintenance costs, limited suitable locations due to specific tidal patterns, potential environmental impacts on marine ecosystems, and the variability of tidal forces which can affect the consistency of energy generation.
Tidal energy has high initial infrastructure costs, limited suitable locations for tidal power plants, and environmental impacts on marine ecosystems. Additionally, the technology for harnessing tidal energy is still relatively new and not yet economically competitive with other renewable energy sources.

Tidal energy is only useful where the water runs strongly, for example, a river mouth that has a narrow outlet to the sea, or a large bay with a small outlet. Where the water runs strongly, a turbine can be placed to generate electricity.The cost, the locations, the environmental impacts on marine life, and the limited technology is what is not causing the widespread use of Tidal energy. Either all or most of these things contribute to why some places can't either afford, or can deal with all of the impacts that could occur with this energy type.
Burning Coal
Some environmental impacts on potential energy sources include habitat destruction for hydropower dams, carbon emissions from burning fossil fuels, and land use changes for biomass energy production. It is important to consider these impacts when evaluating the sustainability of potential energy sources.
Some environmental groups oppose tidal energy due to concerns about its potential impact on marine ecosystems, wildlife, and habitats. There are also concerns about the disruption of sediment transport and fish migration patterns that could result from tidal energy installations. Additionally, there may be worries about the long-term feasibility and sustainability of tidal energy as a renewable energy source.
