Tidal Energy - Future Turbo Power!

Select Language Chinese Arabic French German Italian Japanese Korean Portuguese Russian Spanish English

If there is one thing we can safely predict and be sure of on this planet, it is the coming and going of the tide. This gives this form of renewable energy a distinct advantage over other sources that are not as predictable and reliable, such as wind or solar.


Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity. Tidal power has great potential for future power and electricity generation because of the massive size of the oceans.


Tidal turbines are a new technology that can be used in many tidal areas. They are basically wind turbines that can be located anywhere there is strong tidal flow. Because water is about 800 times denser than air, tidal turbines will have to be much sturdier than wind turbines. They are heavier and more expensive to build but will be able to capture more energy.


This form of generation has many advantages over its other tidal energy rivals. The turbines are submerged in the water and are therefore out of sight. They don’t pose a problem for navigation and shipping and require the use of much less material in construction. They are also less harmful to the environment. They function best in areas where the water velocity is 2 - 2.5 m/s. Above this level the turbine experiences heavy structural loads and below this not enough generation takes place.


Small tidal power companies are taking advantage of the rising interest in alternative energies. Large amounts of coastal waters are being reserved on both coasts of North America by small companies who plan to take advantage of ocean energy technologies, in the hopes that these sites will become profitable sources of electricity.
