![]() The tidal energy generator captures the kinetic energy in the tidal streams to produce electricity. Tidal streams are ocean currents produced as a result of tidal ebbs and flows. Though there are various versions of a tidal fence, the most common is one with a vertical spinning cylinder. This has an arrangement similar to a turnstile, making the rotor blade spin with the water flow. Similar in construction and design to a tidal turbine but comes with a different rotor. ![]() This is one of the basic systems and hence cheaper than the rest. Similar to a wind turbine, a tidal turbine generates electricity when water passing over it turns the rotors of the turbine. Here is a brief description of how some of the technologies used in harnessing tidal wave energy work. This gives tidal wave energy a tremendous edge over other clean energy resources. Unlike most renewable energy sources, tidal wave energy is more predictable as tides follow an established pattern. However, in the ocean’s water, kinetic energy is already present as it is always in motion. Though water is the common factor in hydropower and tidal wave energy, the former needs to convert the potential energy in the stored dam water into kinetic energy by making it flow down. These include tidal turbines, tidal fences, tidal stream generators, and tidal barrages. Diverse technologies are available to capture the tidal wave energy to turn the rotors. The kinetic energy contained in the ocean’s waters can be harnessed to turn the rotors and generate electricity. ![]() The rotation of the earth on its axis, the gravitational force, and the pull exerted on the earth by the sun and the moon make this water move vigorously. You will also find here tidal energy pros and cons.ĭo you know that about 71% of the earth’s surface is covered by water? And the oceans hold a whopping 96% of the earth’s water. This article is an attempt at understanding more about tidal wave energy and figuring out the answers to some of these questions. The ideal way to gauge the potential of new technology is to lay out its pros and cons. How much potential does tidal wave energy hold for the future? Can it become the next big thing and ultimately be capable of replacing fossil fuels? What are the benefits of using tides for energy? The answers to these questions depend on the efficiency, affordability, and universality of tidal wave energy. The tidal turbine is the new kid on the block, though the idea in itself is not new to humans. All we need is efficient technology to harness this ocean energy. Tossing and turning 24×7, waves have incredible amounts of kinetic energy. Our oceans hold an unimaginable abundance of energy, hidden in their turbulent waves. One of the promising discoveries to help us bring down our dependence on fossil fuels is tidal wave energy. As the threat from global warming and climate change worsens with each passing year, our search for clean energy is intensifying.Įven as new technological advances have made solar and wind power cheaper and more accessible, there is enough room in the power generation scene for new players to make their mark.
