Pros of tidal energy9/1/2023 ![]() ![]() Photo Credit: Kenneth Allen CC BY-SA 2.0 1. When submerged, the tidal currents spin the blades much as per wind turbines. The generator is pictured with its blades up for maintenance. Photo shows a tidal energy generator at Strangford Lough, Northern Ireland. However, as with many things, Tidal energy has advantages and disadvantages. With the focus on renewable energy becoming more apparent 6, clean energy is something we have to make use of. Meanwhile, early tidal energy facilities show how leveraging tidal energy is a replacement for fossil fuels. However, renewable tidal energy is still relatively new, and turning tides into energy is still in development. Estimates suggest that the tides could provide us with 700TWh each year. Researchers have found that tidal energy could produce as much as 10–25% of our worldwide energy needs. As the currents flow, they produce kinetic energy and turn it into energy that we can use.ĭue to the ubiquity of tides and their regularity, tidal energy could prove one of the more important renewable energy sources available to us 5. This moving of the tides and the waves that accompany them all generate energy. The ocean covers much of the earth, and it moves around the world via tidal patterns. It is possible to predict the tides caused by the gravitational pull of the moon, many years in advance, so we can predictably forecast the potential for tidal energy creation. Tides are a phenomenon that is guaranteed every day. The movement of our Oceans creates vast amounts of untapped energy. The Bristol Channel in the UK has the second-highest tidal range globally at 15 meters. ![]() The biggest tidal range is in the Bay of Fundy, Canada, where the tidal range is 16.3 meters. During the day, we will see two high tides and two low tides. When the earth, the sun, and the moon align, the gravitational pull will be at its strongest, which results in the largest tidal movements in any month 2. The size of the tides is determined by the new Moon and the full Moon and accordingly alters over the course of a month. While many of us might be aware of tides, how many understand how they are created? Tides are the rise and fall of sea levels in their simplest form, caused by the gravitational pull between the earth and the moon. As a result, we need long-term solutions that we can rely on, and tidal looks set to play a more significant role in producing our future energy needs 4. The environmental effects of traditional energy are devastating. This can include the likes of wind and solar power and, of course, tidal energy. While the planet provides us with fossil fuels, it also provides us with other forms of renewable energy that we can harness. Consequently, we should consider the advantages & disadvantages of tidal energy and the growing role of converting the movement of the tides into clean energy 7. Therefore, we need alternative sources of energy. Along with this, much of this energy plays a significant role in polluting the planet by emitting greenhouse gases. Ultimately, this means that in time, these sources will run out. Much of the energy we use today comes from non-renewable sources. ![]()
