I would guess that it requires considerable investments.

Alternative energy
Tidal energy is stored by converting it into electricity through tidal power plants. This electricity can be used immediately or stored in batteries for future use. Tidal energy can also be used to generate hydrogen through electrolysis, which can be stored and used as a fuel source.
Solar, wind and tidal are three sources of fuel/energy that will only run out at the end of time.
Wave or tidal energy is a great, environmentally friendly means of generating energy. See: http://en.wikipedia.org/wiki/Tidal_power tidal energy is the best energy to use BUT there are a lot of con's to this source also so if you use this be generate of it.
Tidal energy has the potential to replace non-renewable energy sources like fossil fuels (coal, oil, and natural gas) for generating electricity. It provides a consistent and predictable source of renewable energy that can help reduce our reliance on fossil fuels and decrease carbon emissions.

Tides can be harnessed to create low carbon-emitting energy through tidal power technologies, such as tidal turbines and barrages. These systems convert the kinetic and potential energy generated by the movement of water during tidal cycles into electricity. Unlike fossil fuel sources, tidal energy is renewable and produces minimal greenhouse gas emissions, making it a sustainable alternative for meeting energy needs. By tapping into the predictable nature of tides, we can generate a consistent and reliable source of clean energy.
Tidal energy produces electricity without any cost and without any pollution.Fossil fuel oil, when burnt, produces electricity at an economic as well as environmental cost. It also releases long-held greenhouse gas, carbon dioxide, which is causing global warming and climate change.
Tidal power is useful because it generates electricity that is renewable, free and non-polluting. So it is an excellent replacement for energy from fossil fuels (coal, oil and natural gas) which is non-renewable, expensive and polluting (that is, causing global warming).
Does not require fuel to run. 2) Environmental friendly and does not produce any greenhouse gases. 3) Maintenance is low on cost.
No. It is a type of energy taken from the movement of water. Using waterfall would be just like that. Fossil fuels are oil and gas.
