We often talk about photovoltaic systems for domestic use but how are we doing with wind turbines? Wind energy is an inexhaustible source and with the most modern technologies even domestic environments can benefit from it. Before proceeding with the search for the wind turbine to install in our garden, we can understand how much the device would make us in terms of energy.

According to a recent EWEA report, 2011 closed with 235 new offshore wind turbines connected to the grid worth 2.4 billion euros. The European Wind Energy Association (EWEA), in its report, highlighted a slight reduction in production compared to 2010 when a total power of 883 MW was installed and connected to the grid, while in 2011 the power from offshore wind turbines feeds into the network is 866 MW.
In the next seven years, wind energy could meet almost 16 of European electricity needs and would provide half of the electricity needed by the entire continent by 2050. This is stated in a prospectus produced by the European Wind Energy Association. Still according to the EWEA scenario, Europe has all the potential to meet its energy needs exclusively through renewables, in fact by 2050, 50 of the electricity needed by the old continent will come from the wind, while the other half will be supplied by a mix of electricity from clean sources.
Italy is far from the European average also as regards the wind sector. Italian wind farms provide 4.2 of national electricity consumption, a low percentage if we consider that the Danish wind sector ensures 25.9 of total electricity consumption. The Italian reality is also distant from Spain with 15.9, Portugal with a percentage of 15.6, from Ireland with 12 and from Germany which satisfies the electricity needs of the country with 10.6 from wind energy.
Wind turbines are transformed into works of art, the purpose? Sensitize Italians to the issues of renewables and bring them closer to wind energy. It was an internationally renowned artist who took the wind turbines and transformed them into art installations. Horst Gläsker, of German origin, has always worked between art and science and today he did not want to exclude sustainable technologies.
It rises in Sardinia and covers an area of four thousand hectares of land with about 70 turbines. It is not only the largest wind farm in Italy but also ranks among the most important wind farms in the entire European Union. An annual turnover of 50 million euros and the development of new jobs are expected.
Wind energy is renowned for its low costs but will soon be famous for the innovations it offers; wind power will kick off a real revolution in the renewable sector: testing of completely floating offshore wind turbines has begun. The plants do not include foundations but completely floating structures that float on the waters off the coasts anchored to the seabed only with steel cables.
Wind energy is renewable, sustainable and low cost. The industry has improved the performance of Turbines and Blades, wind technology will continue to improve becoming more and more convenient for the economy and the environment. Long-term projects see wind energy alongside solar energy in a scenario where coal-fired power plants will gradually decrease.
In the renewable energy landscape, wind energy is the lowest cost and is often seen as the solution to the energy crisis. Unfortunately, like most technologies, it has a downside with negative implications: an unsightly impact on landscape assets, low efficiency and the threat to birdlife.
Nociglia is an Italian town in the province of Lecce, in Puglia. For years now, efforts have been made to give life to a project for setting up a wind farm in the municipality of Nociglia. Salento is in full turmoil because citizens do not want the construction of a wind farm. The project was proposed by the company Eolica Energia F Srl which in February 2006 had the support of the Puglia Region.
In the northern part of Kenya, in an arid area, the largest wind farm in Africa will soon be built. The project involves the construction of about 365 wind turbines located near Lake Turkana, the largest desert lake in the world.When we talk about Africa, there are many other images that come to mind: Kenya is a state in Africa Eastern, Nairobi is its capital.
While in Italy it is manifesting itself to counter the spread of turbines, the German energy plan will be based on wind energy; the purpose of the country is a 100 green commitment. The wind farms planned for Germany will cover an area equal to six times the city of New York, according to German Chancellor Angela Merkel and has been described as the most important energy project of the last seventy years.
This time it is Europe that leads the way over the United States. Offshore wind power is not popular in the US at all, along the American coasts no turbine has yet been installed but things are changing and the first US prototype will be installed off the coast of Virginia, while in Europe new prototypes are being tested for the offshore wind power, like the floating turbine, the US is preparing to install a single 5 megawatt wind power unit.
According to investigations concluded by the competent authorities, the Camorra is aiming for the green economy and is doing so through the wind energy sector. Under investigation some projects in Campania, Molise and Sardinia. The court of Santa Maria is investigating some projects of a company employed in renewable energy and purification plants; the company is under seizure.
Wind power enhances the Italian landscape heritage, it does not destroy it! There are those who persist in saying that the wind turbines alter the naturalistic assets of the Italian territory but this thesis is dropped by the photographic reportage by Giovanni Presutti, a Florentine artist who, with photographic equipment on his shoulder, shot the boot immortalizing him on film. glimpses of the Italian wind panorama.
Tula is an Italian town in the province of Sassari and thanks to wind energy, the approximately 1,700 inhabitants will not have to pay the new house tax. For the rest of the Italians, the IMU payment deadline is getting closer and closer but not for this handful of Sardinian inhabitants. It is the mayor who gives the good news: "no IMU for the citizens, thanks to the wind farm we are in balance".
A floating platform with a diameter of 480 meters equipped with 36 wind turbines with a power of 54 MW. Is this how wind energy will come to life off the coast of Malta, Sweden or Cyprus? The government of Malta is considering the possibility of relying on the project of the Swedish developer Hexicon, but the race for floating wind power is not only for the Island of Malta, two other countries are in the running.
They destroy landscape assets, kill birds and increase global warming. These are the accusations made against wind energy but there are those who say exactly the opposite. According to authoritative rumors, it would be a plot to favor coal fuel sources. There is no peace for wind farms, new research would show how wind farms increase the phenomenon of global warming.
The debate on wind power continues and is becoming increasingly heated. This time it is the Royal Society for the Protection of Birds which has published a very interesting research. The gigantic wind turbines do not harm volatile species, so much so that the Bird Protection Authority has decided to build a 100 meter high wind turbine, right near its headquarters!
There are too many beliefs about wind energy to dispel, especially since the installation of wind farms for the production of renewable energy is constantly growing. The United States, Europe and China have very aggressive plans for the spread of wind power over the next 10-20 years. With the growth of the wind energy sector, false myths are also spreading.
On some summer evenings, the Uruguayan wind satisfies 80 to 90 of its energy needs. Uruguay is a small country and its energy hunger could be almost totally satisfied by wind farms, many projects and various realities already active. This is how little Uruguay will become a wind energy giant.
