In fact, the 2011 brings good news after years of discussion and controversy: it seems that the mammoth project Desertec he is leaving.

Desertec The project involves the use of many forms of clean energy such as tides, waves, biomass in addition to 'wind, photovoltaic and thermodynamic.

short, a huge machine that moves in the direction of a real challenge to boost renewable energy as primary producers of energy.

The wind program aims to feed the large helical generators with strong and steady wind that blows in the north of Europe 'and that affects Britain, Ireland, Sweden, Denmark, France, Germany, Belgium, Netherlands, Luxembourg and Norway.

To accumulate this surplus wind power, have decided to create natural barriers given by the Norwegian fjords.

These will be wide open with hydroelectric dams producing basins fed with water pumped by wind power in excess, and then raise up the dams and exploit the cascading effect resulting in the production of energy in the turbines downstream, when the wind is in default with respect to global demand.

Crossing from northern Europe to north Africa, the exploitation goes from wind to solar, where we talk about for years and is studying to harness solar energy in the Saharan area.

The idea is based on the fact that the production of solar energy that comes in about 6 hours on the African continent is the amount of solar energy equal to that consumed around the globe in a year.

calculations say it would be enough to cover with solar only 0.3% of North African and Middle Eastern deserts to provide energy to the whole Europe as well as the needs of the producing areas.

In this gigantic plan of work, the Italian interest is represented by three Italian companies such as Terna, Enel, and Italgen (Italcementi). These contribute to the construction of the Maghreb in the area of \u200b\u200bsolar power plants.

Desertec solar facilities in the project, promoted by the physicist Gerhard Knies, are based on solar thermal power technology , one already implemented by the project Archimedes Rubbia Priolo and Spain. Solar energy is reflected by mirrors and focused into a tube to heat the liquid and give place in a natural circulation in the system. The flow of the liquid generates useful energy to drive turbines and thus generate energy.

These systems are able to meet the growing demand for seawater desalination and electricity production in those countries and also to generate clean power that can be transported to Europe via cables to high-voltage direct current (HVDC High Voltage Direct Current) with overall losses limited to 10-15%.

the project over the years has not been without its critics and the excessive cost without doubt has been brought to the fore. The project requires an investment of Desertec € 400 billion. This technology is still experimental suffered not a little concrete in accessing funding. Of course today the start of the project depends on the political and social and economic situation which is investing in these hours all North African countries included in the program.
