Norwegian Company Develops World’s Largest Wind Turbine

Posted in Energy Industry | Wind Power | Wind Turbines

World's Largest Wind Turbine As fossil fuels continue to diminish and climate change poses an ever-increasing threat, scientists around the world are searching for new and more efficient methods of generating energy. Wind energy is one of the more promising alternative energy sources and Norwegian scientists are currently in the development stages of what promises to be the world’s largest wind turbine. As if creating the biggest wind turbine in the world was not enough, it also floats. Current plans for the world’s largest wind turbine have the machine standing 533 feet tall.


The proposed rotor diameter of this machine is 475 feet. Obviously, these gargantuan dimensions make it difficult to imagine many places able to accommodate such a device. Fortunately, the floating design makes the turbine suitable for open ocean use.

In addition to being the world’s largest wind turbine, the proposed machine (which is to be built by the Norwegian company Sway), will also be the most powerful. A single floating turbine will be able to generate 10-megawatts to power more than 2,000 homes. These figures make this proposed new design at least three times more powerful than the existing wind turbines in use today.

The floating design gives this generator a huge advantage over other wind-power generators because the device can be placed in deeper water. The machine’s tower is a floating pole filled with ballast beneath the ocean’s surface. This gives the world’s largest wind turbine a low center of gravity, which prevents tipping. The generator is anchored to the sea floor with a single pipe and a suction anchor. This design allows the turbine to tilt 5-8 degrees as well as rotate freely to generate power from any wind direction.

Sway plans on installing the device in 2011. The prototype of this machine will cost an estimated $67.5 million dollars. Sway plans on testing the design on land first in Oeygarden, Southwestern Norway. If the design is successful, Sway will continue testing seafaring prototypes.

Currently, Norway is one of the world’s top oil and gas producers. Despite this fact, Norway generates most of its own power from hydroelectric plants. Norway’s dedication to designing and building the world’s largest wind turbine showcases the countries commitment to alternative energy, and serves to further illustrate how important this cause actually is. If the world’s largest wind turbine is a success, it will mark a major stride in humanity’s quest to reduce its dependence on fossil fuels.

    I see how this would be the future of how we obtain energy. The problem is ensuring that the company that owns each of these can effectively draw the power gained to their company stockpiles so they can transfer the power to the consumer. Inevitably each consumer will have the opportunity to have their own alternative power sources to aid in drawing power to these energy corps. Hopefully it will lower the costs of energy across the board.

    It sounds like an interesting idea. I can picture numerous wind turbines in the ocean, out beyond where they would bother anyone. What about currents and hurricanes? How does the power get to the shore?

    Great! At least people are doing something about saving the earth by reducing pollution, let them do more, left and right, fill up the place with them, save a few oil barrels.

    Good to see that innovation is still going ahead. People complained a lot when wind farms were initially built on land, but with deep water use, it is out of sight, out of mind

    Its amazing to see the Energy companies taking so much interest in wind power coz its high time now. I just hope that similar gigantic steps are also taken for geothermal and ocean thermal energies… mere earth earth days won’t help, there is more need to manufacture than to conserve as world’s population is going to increase not remain dynamically static.
