Renewable Energy They are considered renewable energies those forms of energy generated from sources whose use does not affect natural resources for future generations or for their intrinsic regenerate or not "exhaustible" in the scale of time "human". While from a purely scientific definition that has not particular sense, because according to the postulates necessary to define the first law of thermodynamics, so nothing is created or destroyed, all forms of renewable energy, from a point of view social, political and therefore, creates the distinction between use today considered sources of renewable energy (solar, wind, etc. ...), whose current use does not affect the availability in the future, and non-renewable fossil fuels (oil, coal, natural gas) and nuclear (uranium and plutonium), which had long periods of training, much higher than current consumption, are limited in the future. From this point of view, the inclusion or otherwise of a particular source, such as termovalorizzazione, is subject to many factors not necessarily scientific, creating de facto situations not uniformity of opinion among the various stakeholders (NGOs, governments, administrations premises). Index [Hide] • 1 Classification of renewables • 2 Environmental impact • 3 Production renewable Italian • 4 Notes • 5 See also • 6 External links Classification of renewables [edit] Production of electricity from renewable sources in Italy. Established by data published by GSE / Terna Variations percentage of renewable energy sources in Italy. Established by data published by GSE / Terna As already stated, there is no definition of renewable sources, exists in several different areas views on whether one or more sources in the group of "renewable". According to the Italian reference, are considered "renewable" "... The sun, wind, water, geothermal resources, tides, wave and the transformation into electricity plant products or waste organic and inorganic. " ([1]) Rientrerebbero in this field thus: • Energy hydroelectric Or tidal energy (or tidal) Or energy wave Or energy talassotermica • Geothermal • Solar energy (thermal and photovoltaic) • Energy wind • Energy from biomass Biogas or Or Vegetable oil Or Biodiesel Or Cippato • Termovalorizzazione of CDR About the latter, it is worth noting that only in Italy (in breach of European directives) is considered totally renewable energy produced by termovalorizzazione (ie from incineration) where the EU considers "renewable" only the organic waste (ie waste) [2]. Source renewable, for the EU, means reproducible from the Sun through photosynthesis and the trophic chain. Although "non-fossil, nuclear energy, is not unanimously considered renewable, because its use is still limited by reserves of materials that do not regenerate at the same speed with which they are consumed and yet, unlike other cited pose serious security problems and disposal of waste products. Moreover, in some studies is not considered "renewable" energy, geothermal, while environmentalists movements, often discarded energy produced from municipal solid waste, as these are also produced with fossil raw materials or synthetic products not biodegradable (while only the organic waste would be considered "renewable"). Another distinction is often made between renewables "classical" (mainly hydroelectric and geothermal) and renewable sources "new" (also called "NFER), which are generally included solar energy, wind and biomass . In the production of electricity renewables are finally classified "sources programmable and non-programmable sources", as that can be programmed according to the demand for energy or not. According to the definition of Electrical Services Manager (GSE, also known as GRTN), in the first group included "hydroelectric plants and a reservoir basin, municipal solid waste, biomass, plant treated using fossil fuels, fuels process or residues, while in the second group (not programmable) are "production facilities fluent hydroelectric, wind, geothermal, photovoltaic, biogas" [3]. Environmental impact [edit] They are sources of energy that could lead to a sustainable development without damaging is the nature and for a time limit. Some of these types of energy (especially solar) can be microgenerate, that is produced in small household systems that can meet the energy needs of a single home or small group homes. This allows you to save the energy that is lost during distribution of electricity, for example on power, although also involves the need to redefine the structure of the national electricity grid. We must remember that it is still under discussion whether it is really possible to meet all the current energy needs of the planet with the potential energy from renewable sources. Production renewable Italian [edit] In 2006 the Italy produced almost 52.2 TWh of electricity from renewable sources, equivalent to 15.4% of total electricity demand, with 12.05% from hydroelectric sources and the remainder of the sum geothermal and wind (ie, approximately 90% of production is produced with renewable plants called "programmable"). [4] With these values, Italy is the fourth producer of electricity from renewable sources in the EU 15 [5], although still far from the objectives laid down Community, which include the production of 22% of energy demand from renewable sources by 2010 . It is also worth noting that in recent years the Italian renewable energy production has grown very little or has remained stable, despite a strong growth of wind power source (but with low rates), due to a substantial preponderance of stagnation hydropower production, in fact almost reached the saturation of economically exploitable potential. And despite the incentives, Italy must also deal with legislative delays and adequacy of distribution networks.
