He climate change It is an undeniable fact that affects human beings in various aspects (social, economic, ecological, etc.), the price of electricity and fuel continues to increase in a chilling way day after day, without it seeming that the rise will end. . The main reason is the exploitation of non-renewable natural resources on the planet to produce energy, contributing to the excessive generation of carbon dioxide and other greenhouse gases.
The wind power It is presented as one of the most used renewable energies, along with photovoltaic, and efficient in areas where the wind resource is abundant, such as coastal areas, high mountains or at sea.
For obvious reasons, it is tedious to install wind mills in coastal areas due to the difficulty of the terrain, as occurs in high mountainous areas, adding the complexity of transporting the towers and blades of the mills.
But all these inconveniences can be solved by installing them over the sea.
The sea surface in areas near the coast has a depth of between 5 and 35 meters on average, making it possible to install pillars to Wind generators. In these areas, the wind is a practically inexhaustible raw material, since it is always available and moving.
There is the precedent of the North Sea, whose installation generates electricity for all the countries that bathe its coasts in northern Europe. Specifically, we talk about Horns Park REV II in Denmark, which has a total of 91 turbines capable of producing 2.3 MW of power.
This idea of energy production has led to China to create a “super wind turbine” which will be installed in the sea. This wind giant has measurements that reach a maximum height (tower plus blade) of more than 240 meters (the blades have a length of 118 meters, which can sweep an area of about 46,000 square meters, the equivalent of several athletics tracks) , which allow the generation of between 80 and 90 GWh of electricity, an enormous amount of energy that is capable of giving a 180º turn to the use of this energy to produce electricity.
This model is called “MySE 16.0-242” will begin manufacturing in 2022, delaying its commercialization for a couple of years, until at least 2024 if everything goes smoothly. The main advantage of this marine wind turbine from an economic point of view is that it will allow the cost of the offshore wind energy, which is currently variable, being able to increase the contribution of this type of energy by around 15%.
Currently, wind energy is more expensive when it comes to megawatt hour generation, with wind production costing $120 compared to photovoltaic production, which is around $33. Thanks to the increase in energy production that these mills located on the high seas can generate, wind production can become cheaper, reaching the same level as photovoltaic, causing its cost to be reduced by around 43% by the year 2050.
The response of another power in the world of energy such as USA has been that by 2023 the installation of a gigantic wind farm in the state of Massachusetts, which includes generators latest generation Haliade-X type from General Electric.
This turbine has a 12 MW generator, offering the capacity to lead the wind market compared to other competitors and producing 45% more energy than the rest of the available generators, reaching 67 GW annually, enough to supply 16,00 homes ( the new Chinese giant reaches 22,000 homes).
This model has had a production of between 3 and 5 years and more than 400 million dollars of investment and in 2021 it will be operational. Its height is 260 meters above sea level and its blades measure 107 meters in length.
