Tidal energy is the sun and moon’s influence over the ocean. One of the biggest advantages of tidal energy is that the tides are predictable and occur all along the oceanfront however, the current is not constant but. Tidal energy is a form of ocean energy that can be our ultimate source of clean, renewable power. This building was built in Olhão, Portugal in 1280. Tidal turbines are very similar to wind turbines. Dating back to as early as the 9th century, tidal mills were constructed throughout Europe, consisting of an artificial tidal lagoon and a water gate to control the flow of water that turns the waterwheel to grind wheat into flour. This process allows for energy to be harnessed consistently with the movement of the tides. Gravitational and centrifugal forces are the two forces that rise the tides.įinally, on the definition of tidal energy, it is a form of hydropower that converts the energy obtained from tides into other useful energy (electricity). Tidal energy is one of the oldest forms of energy used by humans. Tides are long-period waves that occur in an ocean, which are caused by the combined gravitational effects of the sun, the moon, and the rotation of the earth. Because of these features it is unique and suitable to use it as a. Unlike the wind, solar, thermal energy etc., tidal energy is something that has a long term perspective and it can be forecasted more accurately. Likewise, when the moon and earth’s gravitational field are perpendicular to each other, their influence becomes weak, causing the water to flow away from the shore resulting in a low tide condition. Tidal energy can be considered as one of the best existing source of renewable energies. When the earth and moon’s gravitational field are in a straight line, the influences of these two fields become stronger causing millions of gallons of water to flow towards the shore resulting in high tide conditions. It is known as high tide when the sea level rise and it’s called low tide when the sea level falls. At a particular place, tides usually occur twice on a lunar day. This gives tidal wave energy a tremendous.

The alternate rise and fall of the sea levels are caused by the gravitational forces of the sun and moon and the evolvement of the earth. Unlike most renewable energy sources, tidal wave energy is more predictable as tides follow an established pattern. For clarification, you should understand the term ‘tides’ Advantages of Tidal Energy It is a renewable source of energy It does not cause any pollution to the environment The lifespan of tidal energy plants are long.

It can also be said to be renewable energy in which tidal action in an ocean is converted to electric power.

It relies on the rising and falling of sea levels and tidal energy devices convert the energy gained from tides into electricity. Tidal energy or tidal power is a form of hydropower that is harnessed by converting tide energy into useful forms of power.
