Three hundred and nine square kilometers of occupied sea. To install 32 floating wind turbines which will be 355 meters high at the tip of the blade, at distances between 19 and 29 nautical miles (between 35 and 55 kilometres), above a seabed ranging from 250 to 1350 metres.

These are the gigantic numbers of the offshore plant that the company "Parco Eolico Flottante Mistral Srl" - on behalf of others - wants to install in the sea of Sardinia, between Capo Mannu and Capo Marrargiu, in front of almost 70 kilometers of coast, the western one , divided between two provinces: Sassari and Oristano. With the natural monument of S'Archittu in the middle.

But the intervention is not over. There is also a submarine cable and works on land, including an exchange station, which will cross the territories of Alghero, Putifigari, Ittiri and Bessude. The impact on the landscape, we read in the documents, "will be minimal". But it's there. And the blades are also visible from the ground in the photo simulations filed by the company. Which assures: «With a total of 480 MW of installed capacity, the park will have a net energy production of 1,398.24 Gwh per year, guaranteeing electricity for over half a million Italian families». A forecast provided by specialized technicians. Which gives rise to a question: if a single system - like this one - could guarantee light in the homes of a third of the Sardinian population, what is the meaning of 28 other requests for connection to the Terna grid for offshore wind farms on the island alone, which are they added to the other almost 800 onshore wind and photovoltaic systems?
