Tidal energy is a form of hydropower that converts the energy of tides into electricity or other useful forms of power. It's also a renewable source of electricity which does not result in the emission of gases responsible for global warming or acid rain associated with fossil fuel generated electricity. Use of tidal energy could also decrease the need for nuclear power, with its associated radiation risks. The few studies that have been undertaken to date to identify the environmental impacts of a tidal power scheme have determined that each specific site is different and the impacts depend greatly upon local geography. If fossil fuel resources decline during the 21st century, as predicted by Hubbert peak theory, tidal power is one of the alternative sources of energy that will need to be developed to satisfy the human demand for energy. Whatever the process is a traditional power generation using a alternator and mechanical energy (for rotation) are collected from tidal energy using a simple floating device but create a artificial floating dam to hold huge energy, a system also involved to convert linier motion to rotary motion not using any traditional turbine.
