Micro-Aeolic in Residential Districts: A Case Study in Sant'Arsenio (South-western Italy)

The renewable energies are the sources of energy that are derived from inexhaustible natural resources. In other words, they are regenerated at the same speed of which they are consumed and that the people have at their disposal. In new millennium, we can find multiple typologies of renewable energies, such as the sun and wind. The latter has had great development and evolution due to both the incentives that have been issued and the greatest attention that it is giving to the environment protection. At the beginning, the integration of wind power in the people life was very difficult, because the first plants had very big dimensions that result in a big trauma to the world population, named "NIMBY" (Not In My Back Yard). For this reason wind plant was evolved in a more soft idea that has brought both the change in the daily life of the modern society and the respect of the morphology, the urbanism and the city architecture. In Europe, the wind energy had a big increase getting better than the one in United States of America. Germany and Denmark are the greatest producers of wind energy, thanks to the quantity of the available rural spaces but also to the correct effect political strategies, among which the constant subsidies from the governments. in Italy, instead, the wind energy boom occurred at the end of the nineties. Anyhow the Mediterranean country is reaching the standards of the other European countries through the numerous installations in Puglia, Sicily and Campania,. However, so far we have only referred to megawatt or multi-megawatt plants, that have a big size and are installed outside the urban context or in ample hilly plains. For instance, in Italy such plants are installed in the great green plain in Puglia or along the Apennines’s. Different is the micro wind plant that can be installed in an urban context and inside buildings thanks to the advanced technology and to the reduced dimensions . This kind of plant had a notable development in the last years and can easily fit with the daily life in Europe as well in other parts of the world. A case study of micro wind power in the new scenario is the (here proposed) case of Sant'Arsenio in Campania. It is a small and uninhabited village, that would allow the insertion of the equipment because of the free green spaces: this experimental work we describe here is aimed at promoting the coming back of citizens into the village.
