throughout the country are spreading the Solar Buying Group, also to help individuals and families to optimize the investment in solar panels. Soon they'll also wind sources, geothermal and water.
Last Thursday, the Venetian Councillor Frederick Sboarina Environment presented the study commissioned AGSM that porteràa install Bentegodi stadium in Verona's largest photovoltaic plant in Italy, can generate 935 000 kWh per year .
solar panels connected to the electrical grid (ie able to resell the electricity to the network) are the energy technology that is growing more rapidly in the world, with increases of 50% in 2006 and 2007, according to data collected in the Renewables 2007 Global Status Report of the company REN21 ( attached the pdf ). Access to solar energy is not, however, only the prerogative of large companies and power companies: With the increasingly rapid evolution of technology (driven by the price of fossil fuels and environmental needs of the planet) and all 'introduction into the financial 2007 of the new Energy Bill today to install a photovoltaic panel has become an investment that can pay for itself completely in a few years, allowing even sell excess energy to the electric company.
In Italy the regions that have introduced more photovoltaics including privately are those of the North, such as Lombardy and Veneto. In many ways, however, the exploitation of solar energy is even greater opportunity for the sunny southern regions, including Sardinia, where a series of meetings organized in collaboration with Legambiente at the Faculty of Architecture of the ' University University of Sassari , is getting a great success with the public interested in learning about the opportunities offered by GAS, buying groups for Solar.
"The expenditure for the planting of a house of average size is around 20.00 euro - said Luciano Deriu , regional secretary of Legambiente - and can be recovered in about 8 years if 'investment liqud or 11 years if financed by a bank loan. Through incentives offered by the Energy Bill can be achieved incredible economic performance and secure. " The main difficulties concern the choice of a supplier and the issues linked to legal requirements, building and nature. "This gas is essential - Deriu continues. The more people who together are able to find the best supplier for installation and MAINTENANCE, as well as to obtain more favorable economic conditions can be settled by the banks and the bureaucracy. "
GAS The first was born in Sardinia thanks to an initiative of the mayor of Loceri, Carlo Balloi, which involved over one thousand families. Following similar initiatives were born in the province of Sassari and Alghero, where, precisely, the faculty of Architecture under Professor Cecchini has repeatedly filled the auditorium with people interested in learning more.
next-generation solar panels for homes based on the ability of silicon trasformrare solar energy into electricity. The most common technologies (ranging in price and performance) are monocristalliuno silicon, polycrystalline silicon and silicon amoerfo, which costs less and has a shorter life time. In general the photovoltaic modules are larger than last for 50-100 years but is likely to need to be changed every 25-30 years for obosolescenza technology. The most pleasant is surely the chance to forget the entire bill for electricity, gas and even sell excess energy ENEL
After solar energy, the next source rinnovaible that will make its way into the homes of Italians will be the 'wind . In this case, the operation of the generator is even simpler: a shovel, blown by the wind, transforms kinetic energy into mechanical energy, which is used to generate electricity. The problem related al'utilizzo of "small wind" are primarily of an aesthetic nature: it is difficult to imagine the intallation of too many blades on the roofs of houses or in the many protected areas in terms of natural and historical architecture. After approval of a new law (see also Site of ' ENEL) in early 2008 has been allocated the first funds state: "We should return to the production of wind energy in agricultural production, taking advantage of fields and land with the same incentives - Deriu concludes, the idea is to 'Cultivating the Sun and the Wind with the Earth'. "
land and water are two other renewable energy sources from which we will in future benefit to the national needs. Also according to REN21, Italy is already the fourth country in the world production capacity of small-scale energy idorelettica and is in fifth place for the use of geothermal energy. The U.S., which in the plan outlined by Obama exploit more and more renewable energy sources, but must make up ground. "Thanks to Pioneer Energy Efficiency Program Assistence today are offered incentives covering up to 65% of the initial expenditure for the installation of photovoltaic systems, wind, geothermal and hydro," says John Pabon, president of the company JPHomefunding that helps individuals to obtain funding to transform the electricity bill in the installment of a loan for generators based on renewable energy, "loans to cover the remaining costs are seen as a leading resource for the economy to a sustainable future."
