Why do we use tidal energy




















We can use tidal energy to supply electricity to our homes and businesses. We can use tidal energy in some places instead of burning coal and oil that contribute to global warming. Tidal generators or turbines work like wind turbines, except it is ocean currents, not wind, that turns them.

The spinning turbine is connected to another device that produces electricity. The electricity then travels through wires to a city where people need it. Tidal turbines generate electricity from the ocean's tidal currents. Shown are two different turbines raised out of the water for servicing or installation.

The best way to capture tidal energy is to place the turbine in a narrow channel between two land masses. When the tide comes in, the water rises on one side of the channel and pours down the channel to the other side. Date Posted: 14 August - categories: blog. Tidal energy is created using the movement of our tides and oceans, where the intensity of the water from the rise and fall of tides is a form of kinetic energy.

Tidal power surrounds gravitational hydropower, which uses the movement of water to push a turbine to generate electricity. The turbines are likened to wind turbines, except they are positioned underwater. The weather in the Scottish Isles allows for the largest production of tidal power in the UK — did you know that the latest figures have shown that Scotland produced enough energy from wind farms in the first half of to power up to 4.

Nearly double the amount it has. Across the world, tidal energy is improving, as engineers develop new concepts and technologies to increase energy demand.

Tidal can be harnessed in three different ways; tidal streams, barrages, and lagoons. However, as we are still waiting on tidal energy to become more economical, there are a few alternative ways that we can capture tidal energy, highlighted in the video below. Tidal stream generators draw energy from water currents in a similar way to wind turbines drawing energy from air currents. However, because water is times more dense than air, the potential for power generation by an individual tidal turbine can be greater than that of similarly rated wind energy turbine.

Intertek works alongside engineers and marine construction specialists to ensure precise understanding of techniques and applications that assist you during all phases of your tidal energy project. During the developmental stages of your project our team provides you with tidal energy resource assessments, site selection support, baseline assessments, constraint mapping and project planning. Our experts help you navigate complex regulatory requirements to ensure compliance during the licencing and permitting phase of your project.

Intertek also provides you with data reviews, field surveys, geophysical and geotechnical assessment ; hydrodynamic modelling ; coastal process assessment , water quality assessment and environmental impact assessment. Intertek helps you overcome a variety of regulatory and operational challenges during construction and installation of your tidal project by providing metocean assessments that help you understand weather constraints.

We also offer Integrated Environmental and Modelling Assessments IEMA that deliver a comprehensive and quantified environmental assessment, which helps you better understand the effect your tidal energy project has on the environment and assists you during the licencing permitting process. Our Geographic Asset Information and Management System GeoAIMS helps you store, access and analyse large volumes of data generated throughout the construction, operation and maintenance phases of your tidal energy project.

We use the information stored in GeoAIMS to ensure that effective quality control procedures and project management practices are established and executed. Large predator s like sharks would not be able to penetrate the lagoon, so smaller fish would probably thrive. Birds would likely flock to the area. But the energy output from generators using tidal lagoons is likely to be low. There are no functioning examples yet.

China is constructing a tidal lagoon power plant at the Yalu River, near its border with North Korea. A private company is also planning a small tidal lagoon power plant in Swansea Bay, Wales. Using DTP, enormous dams as long as 50 kilometers 31 miles would extend straight from the shore into the open ocean. Often used as a source of hydroelectric power.
