The energy generated from the tides obtained in the sea or ocean is called tidal energy. Tides in the sea or ocean produce tide and thus tidal energy twice a day due to gravitational pull of the moon and sun on earth.
Tidal energy is a renewable energy powered by the natural rise and fall of ocean tides and currents. Some of these technologies include turbines and paddles.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.
Energy output from tidal power generators is predictable since we can accurately predict when tides occur. This makes tidal energy reliable and easy to integrate with the grid. It is also sustainable because its energy comes from the lunar and solar cycle.Tidal power is already currently located in a number of countries including South Korea, the United Kingdom, France, Russia, China, and the Netherlands. The map below shows the countries that are involved with tidal energy.
The construction of tidal energy projects can take up to 10 years. ... Additionally, water is much more dense than air, thus tidal energy is more powerful than wind energy. Unlike wind, tides are predictable and stable; therefore, tidal generators are steady and produce a reliable stream of electricity.With total installed tidal power capacity of 511MW, South Korea is leading the way globally, according to the information provided by National Energy Board of Canada. South Korea is followed by France with 246MW, and the United Kingdom with 139MW.
