![]() Tidal power can also contribute to erosion. This can cause problems for coastal communities that rely on the tides for things like fishing and transportation.ģ. Tidal power plants can alter local water levels. The movement of the water turbines can disrupt the natural migration patterns of fish and other marine animals. There are a few disadvantages to tidal power, but they are mostly environmental. Tidal Power 101-Working Animation | Pros and Cons | Renewable Energy Series ![]() This makes it difficult to rely on tidal power as a sole source of energy. The tides ebb and flow, meaning that the amount of power generated by a tidal plant can vary significantly from day to day or even hour to hour. ![]() Finally, tidal power is not a consistent source of energy. The construction of dams and other barriers associated with tidal power can also have an impact on the environment. Tidal turbines can disrupt local ecosystems, affecting the creatures that live in and around them. ![]() There is also the issue of environmental impact. This means that the initial investment can be quite high. They must be located in areas with strong tidal currents, which are often difficult to access. For one, tidal power plants can be very expensive to build and maintain. However, there are some drawbacks to this technology that must be considered. Tidal power has been touted as a clean, renewable energy source that can help reduce our reliance on fossil fuels. Tidal turbines can also cause noise pollution and visual disturbance. Tidal power is a renewable energy source, but it is not as widely available as other renewable sources such as solar or wind power. Tidal dams, barrages, and fences may affect commercial and recreational shipping patterns requiring the need to find alternative routes or costly systems to navigate through a barrage or dam systems.The disadvantages of tidal power are that it is an expensive technology, it can only be harnessed in certain locations, and it has environmental impacts. This build up affects a tidal basin ecosystem in negative ways, causing habitat changes for aquatic life as well as for birds that may rely on low tides to unearth mud flats that are used as feeding areas. These dams may also cause silt to build up along the dam. Tidal energy systems that use dams may restrict fish migration. Tidal power systems are currently expensive to develop and they cannot be built in any location. There are a limited number of locations worldwide that have tidal ranges large enough to make tidal power cost-effective. It is also sustainable because its energy comes from the lunar and solar cycle. This makes tidal energy reliable and easy to integrate with the grid. ![]() It does not require the transport of fuels or disposal of waste products.Įnergy output from tidal power generators is predictable since we can accurately predict when tides occur. Once a dam, barrage or tidal fence is built, the energy production is free since tidal power harnesses the natural power of tides. Tidal energy does not create air, water, or thermal pollution. The infrastructure (basic building facilities and installations) required to develop tidal energy is a tidal power plant to make power and the electrical grid for power distribution. The factors needed to determine the ideal shore location of a tidal power plant include a large tidal range and a funnel shaped shoreline pointing inland. ![]()
