As tidal energy technology begins to advance, the cost of incorporating tidal energy as a renewable energy resource in countries will decrease. There are incredible benefits to using tidal energy despite the drawbacks and high cost. Also, a country must be on an ocean coastline to reap the benefits of tidal energy. The cost for tidal energy can be anywhere between $1.3 million to $1.8 million. ![]() Unfortunately, very few coastal countries are using tidal energy because it can be very expensive, and it can interfere with marine life. Tidal energy even has an 80 percent success rate when converting to electricity. It also does not require any use of nonrenewable resources, such as oil, to power the technology. Tidal energy runs 24 hours a day, 7 days a week, 365 days a year.Īnother benefit to tidal energy is that it does not produce any form of pollution. Tidal energy is the most reliable source of renewable energy because of the continuous change in tidal movements that occur twice a day from the moon’s gravitational force. Tidal turbines are individual turbines that are placed in an area with a strong tidal flow where electricity is created when the water moves through the turbine, and tidal fences are a line of tidal turbines. Tidal barrages are similar to dams in that once the reservoir is filled, the turbines spin to create electricity. The different varieties of tidal technologies indicate how the electricity from the tidal energy is harnessed. Tidal energy is most efficient when the height, mass, and speed of the water are at their optimum level. ![]() Reservoirs collect water and electricity is created as the water moves out of the reservoir through turbines. Like many other forms of renewable energy, tidal power is carbon-free, producing no greenhouse gases or other pollutants. ![]() Underwater devices consist of a vertical or horizontal turbine, similar to that of a wind turbine, which creates electricity as the tide moves through the turbine. Surface devices lay on the ocean surface and capture electricity through the movement of waves. Tidal energy can be captured through a variety of ways. Tidal energy is a form of hydropower that relies on the rising and falling of the sea levels and tidal energy devices convert the energy gained from the tides into electricity. Tides are caused by the moon’s gravitational forces. What comes to mind when thinking of renewable energy resources? Wind? Solar? How about tidal energy? Tidal energy is not commonly thought of when considering the types of renewable energy resources even though it is one of the oldest forms of renewable energy. This type of energy does not generate greenhouse gases or cause pollution through oil spills or burning like fossil fuels do. Tidal turbines generate electricity (NASA) Unlike fossil fuels, tides are a nearly unlimited resource that we aren’t running out of.
