European Solar Days

Welcome
Choose your country:
The first ‘Tag der Sonne’ was celebrated in Austria in 2002. The idea was then taken up by Switzerland and Germany where, in the case of Germany a whole week is now dedicated to this successful renewable energy awareness-raising campaign. “The ‘Woche der Sonne’ in Germany has become the most successful Solar Campaign ever staged and has been a key factor in the increased use of solar energy throughout Germany,” says Gerhard Stryi-Hipp, Managing Director of BSW-Solar.
As an awareness raising campaign, the European Solar Days aim to promote the use of the sun as an energy source for all solar applications, Solar Thermal and Photovoltaic, throughout Europe.
The first European Solar Days will be celebrated on 16-17 May 2008 when over 4000 different events will be staged in ten European countries.
It is now time to bring the Solar Days to the rest of Europe – with Belgium, Italy, France, the Netherlands, Portugal, Spain and Slovenia ready to go in 2008. Other countries are expected to join the initiative in 2009 and it is planned to extend the Solar Days throughout Europe in the future. The European Solar Days will bring together major players from the solar thermal and solar electricity sectors throughout Europe. The European Solar Days, which are coordinated by ESTIF in close cooperation with EPIA, are supported by 25 organisations at a national and European level.

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.

renewable energy

Hi! My name is Ela, I am a Comenius assistant in Enrico Fermi school. With the students we work on the renewable energy e-twinning project. It is very important for us to protect our planet!!! This is a few information that we collect about the energy!
Renewable sources all come from the exploitation of the sun and can be divided into two categories according to the method of extraction. We have two methods. Direct methods include solar collectors, photovoltaic plants and concave mirrors, which concentrate sun rays to multipy the efficiency. Indirect methods are those exploiting nautral phenomena due to the sun, such as wind, sea waves, tides and falling water.
The sun is an inexhaustible source of energy that can be used for a wide range of applications. Passive solar energy, for instance, is captured when buildings are designed to use sunlight to heat rooms. Solar energy can also be used actively. Solar panels convert sunlight into electricity, using photovoltaic solarenergy (solar power). Solar heaters convert sunlight into heat in order to warm water and rooms. This is called thermal solar energy.
Wind energy - the fastest growing source of energy in the world - can contribute substantially to global goals for reducing CO2. Sites located offshore and in remote areas are ideal for wind farms: there is enough potential worldwide for wind farms to generate more than twice the forecast energy demand in 2020.Parallel to the rapid growth of large-scale wind energy production, alternative technologies are emerging, such as sophisticated small-scale urban turbines, which can be incorporated in the architecture of modern cityscapes.
Bio-energy is a cost-effective renewable energy source with considerable economic potential. Bio-energy can be produced with specially grown crops, but in the short term organic residues are the most cost-effective sources of biomass. Currently these come mainly from forestry, agriculture and the food industry. With biomass we can produce energy carriers such as electricity and heat, as well as liquid and gaseous fuels.
So as you see the energy is all around us, the most important thing is to transform it, to store it. If we want to save our Earth and feel safe in our planet we should to use the sources of possesing energy that gives us the nature. And what do you think about it?
