Top 5 little-known facts about wind turbines: Engineers have revealed the secrets of energy harvesting

Wind power plants installed at sea have their own characteristics that wind energy users will be interested to know.

The Energy Efficiency and Renewable Energy Agency of the United States published a material that talked about unexpected facts about the operation of wind power plants. Focus offers the most interesting of them.

Wind turbines in in the open sea are very high

In order to take advantage of the abundant wind resources available in the open sea, the turbines can be scaled up to 300 m, with blades as long as a football field. Larger wind turbines produce more energy, which means fewer turbines are needed to produce the same amount of electricity, resulting in lower costs.

Offshore wind turbines use underwater cables

To transmit clean underwater cables are used to supply electricity to the network. Electricity generated by wind turbines in the open sea is returned to land through a series of cable systems that are buried in the seabed. This electricity is sent through coastal load centers that distribute it to the power grid to power homes and businesses.

Most wind resources are in deep water

The bulk of offshore wind resources are located in areas where the water is so deep that conventional foundations — large steel piles or lattice structures fixed to the seabed — impractical That's why engineers are designing installations that are suited to the unique conditions at each site.

Wind turbines can float

A number of companies are developing innovative floating platforms for offshore wind power to eventually deploy in deep waters. There are four types of floating platforms — buoys, platforms with tension supports, semi-submersibles and barges. Almost 80% of projects plan to use semi-submersible platforms.

Wind in the sea — best solution

In many areas where offshore wind projects are planned, wind speeds are highest during the day and evening when consumer demand for electricity peaks. Most onshore wind resources work harder at night, when demand for electricity is lower.
