In May Lecce hosted the third edition of the Energy Festival, a unique opportunity in our country of an open, secular and pragmatic on the complex issues that revolve around the world of energy, from geopolitical issues to climate conditions, from the delicate Italy's return to nuclear power the green economy and employment that is capable of generating. If it became clear that today we can not afford to give up any source, it became equally clear that only by encouraging research you can come to imagine and identify solutions.

How then fund the research? And how does it fit Italy from this point of view on the international scene? This was discussed in depth at the Festival in a meeting designed ad hoc, 'Research and innovation: what is the future of investing?' Which featured Stefano da Empoli, President of Vice-com, Joseph Campanella of Aifi, Paolo Anselmo Iban. An important opportunity to debate that has developed around to the latest report of the Observatory energy innovation developed by I-com, which analyzes precisely the trend in the industry at the international level.

In response to certain questions Reeds, the Ministry of Development has clarified the procedures to take advantage of the contributions of DL 40/10 for the purchase of energy-efficient homes. On March 25, 2010 was published in the Official Journal of the Decree-Law No. 40, which art. 4, paragraph 1, provides for the establishment of a fund for the support of the application aimed at energy efficiency targets, eco-compatibility and improvement of safety at work reserved to the purchase of energy-efficient buildings, tower cranes, construction earth and trailers. The Ministerial Decree of 26 March 2010, issued in implementation of Decree 40/2010.

For those interested in photovoltaics, the Energy Services Operator (ESO), the company run by the Ministry of Economy and Finance, which is mainly engaged in the sector of renewable energy and the economic and financial aspects related to them, provides incentives that can be used for the installation of a new plant.

The GSE has decided to make the operation more simple and direct, leveraging the Internet for the request: Just log in to the Web Manager after you have registered for the service. Once you have finished recording simply connect to the company's official website, at www.gse.it and go on the menu bar under Tasks, browsing Photovoltaics, Services and finally Request Incentives.

Most of the bulbs that we have at home is incandescent, or has an inner filament that, current flowing, it heats up (Joule effect) becomes incandescent and illuminating the surrounding area.

This type of light bulbs are now an old design, they consume a lot of power, must be replaced frequently (medium lifetime: 1000 hours of operation) but have the advantage of costing little (usually less than 1 euro).

A few years ago are easy to find on the market other types of bulbs called low-energy or Compact Fluorescent: they are generally more expensive (can reach 20 euro) but have the advantage of lasting much longer (about 10-12 times a bulbs) and consume much less electricity (up to 75% less).

The total cost of the electricity bill is made up of a few main factors: energy quota, quota related to network service, general system charge and all taxes and fees attached.

The energy accounts for 60 percent on your electric bill

The energy quota, or the price of energy, is the component that has the greatest impact on the total amount of the bill. The incidence for an average user is about il60 per cent of the total. In particular, the cost refers to the costs incurred by the seller for the purchase and sale of electricity to the end user.

Currently, the potential energy savings achievable through energy efficiency is much greater than the contribution from the use of any alternative source. We believe that in a scenario where the priorities be given to energy efficiency and the reduction of waste the global energy demand would be significantly less than the estimate, and only in this perspective renewables would bring a significant improvement in economic and environmental terms. We emphasize that this will still be a forced and without a quick turnaround we would be faced with short periods of energy blackout.

As early as 15 October, in some parts of Italy come back on plants and central heating. In Italy there are almost 27 million domestic users interested in the use of gas fuels (natural gas and LPG) for heating, hot water and cooking food. The issue of security is always so topical as the statistics of gas accidents more recent 2008 data, the distribution of gas channeled to civilian use, they did detect 175 accidents, 16 of which mortals have caused 19 deaths. The injured were 374. For LPG cylinders distributed in 142 accidents were recorded, of which 19 are mortals who have caused 24 deaths. The injured were 145.

Insurance. Not everyone knows it yet, but in the unlikely event of accidents related to the use of gas there is insurance which is beneficiary to take place automatically, just for the fact that they used the gas distributed through networks. The insurance policy was established by resolution of the Authority for Electricity and Gas and signed by the ICG - Italian Gas Committee, UNI federated entity. The LPG cylinders or distributed in small tanks not covered under this insurance policy.

In these months of inevitable discussion on nuclear energy, we propose a study on the open question of clean and renewable energies. We also recommend you take a look at the site sources-rinnovabili.it

What is renewable energy? Are considered renewable forms of energy generated from sources which by their intrinsic nature regenerate or are not "finite" in the scale of "human" time and, by extension, the use of which does not affect the natural resources for future generations. While from a purely scientific point this definition is not rigorous, since according to the postulates necessary to define the first law of thermodynamics (for which nothing is created or destroyed), all forms of renewable energy would have to be considered, from a point the social, political, and therefore, it creates the distinction between in use today considered renewable energy sources (sun, wind, etc ...), whose current use does not affect the availability in the future, and non-renewable resources, the which is to have long periods of training are far superior to those of current consumption (particularly fossil fuels such as oil, coal, natural gas), and to be present in reserves not inexhaustible on the human time scale (in particular the isotope 235 uranium, the element most commonly used to produce nuclear energy), are limited in futuro.La classification of the different sources is therefore subject to many factors, not necessarily scientific, effectively creating situations of non-uniformity of opinion among the various stakeholders .

Energy savings in condominiums. Upon application of thermostatic valves combined with contacaloria will ensure reduced consumption of heating in old buildings (70% of the total) with centralized

A large part of the condos built in recent years have heating systems designed according to outdated rules and obsolete. These buildings have common systems of heating vertical risers, were built in a time when there was no talk of an energy crisis, are buildings whose heating and 'unbalanced: the occupants on the upper floors are cold, the lower floors and intermediates, open the windows.

The term photovoltaic cogeneration is used to indicate those systems that are able to use a portion of the solar energy is not exploited in photovoltaic processes. It is known that the photovoltaic cells (PV modules or photovoltaic panel) convert into electricity only a small fraction of the solar radiation (between 6% and 15%), the rest is dispersed or is again re-radiated into space. It is therefore of thermal energy that can be recovered. We can distinguish three types of systems:

Daylighting: transparent cells which constitute an integral part of the roof or facade of the building, allowing daylight illumination environments (light radiation is recovered).

PV ventilated: very simple systems in which the rear side of the photovoltaic module is affected by a flow of air that absorbs heat from the module (by cooling and also improving the efficiency), and which is then used for the heating of buildings.
