Having parts that can be replaced, a tidal power plant can work for decades if the sea currents and the height of the tides remain the same. Tidal Power Plants Are Long-Term Projectsīecause tidal cycles never go out (the gravitational forces of the Moon and Sun are always applied to the water in our oceans), building a tidal power plant is a project that will produce clean electricity for a very long period of time. ![]() Tidal cycles are predictable, and this way the power output of a future tidal power plant can be easily calculated before building the plant, and scientists will know this way if building a tidal power in a specific coastal area is sustainable (if the tides are high enough). Is A Predictable Source Of Energyĭespite the fact that the other renewable energy sources known today, such as solar and wind power (energy sources that are generated by the Sun), are intermittent sources of energy, tidal power is also produced by the gravitational forces of the Moon and Sun, but even so, tidal energy is a highly predictable power source. will be capable to replace all these polluting fuels that are used today on a mass scale. Tidal energy alone cannot replace the dirty fossil fuels as the main source of power on the planet, but along with the other alternative sources of clean power, such as: solar, wind, geothermal, biomass, nuclear fusion, etc. ![]() Is An Alternative Source Of Powerīeing an energy source that is renewable (never ends) and also clean (does not pollute), tidal energy is also considered an alternative energy source because in the future, tidal power along with the other alternative energy sources available on the planet, will replace the dirty fossil fuels such as coal, oil and natural gas in terms of energy production for a future without pollution. The tides on planet Earth are generated by the gravitational forces of the Moon and the Sun, which means that tidal power is a renewable resource because the Moon and the Sun will be here to create tides in our oceans for another 4 to 5 billion years.īeing a renewable energy source, tidal energy is considered one of the clean and green energy sources of the future. Tidal energy like all the other forms of clean and renewable energy available on the planet have more pros than cons, which makes them to be the perfect energy sources for the clean future that will follow. ![]() If the gravitational forces of the Moon are aligned perfectly with the gravitational forces of the Earth and the Sun, a very high tide will be produced, which will be followed by a very low tide in the same tidal cycle. When the gravitational forces of the Moon and the Earth are at an angle of 90 degrees to each other, the “low tide” will be created, which means that the large volume of water in our oceans will be moved back to its initial position (away from the shores).Ī tidal cycle consists of a high tide that is followed by a low tide.Īll coastal areas of the planet receive in a time period of 24 hours and 50 minutes two high tides and two low tides.
