In recent years, car registrations in Italy bifuel (petrol / LPG and petrol / methane) have been substantially increased, so as to reach in 2009 record level of 21.7% of the market. Until 2004 the percentage of clean cars sold in the Bel Paese not exceeding 1% ¬ rava and the following years the growth was not exciting at all: in 2005, +1.08%, +1.17% in 2006. Only in 2009, in fact, deliveries of LPG and CNG cars are growing by 357% and 61.5% over the previous year. These data are largely the result of the massive campaign to encourage implementation by the government and local authorities in order to raise awareness among drivers using cars with low environmental impact, but also stems from the increased availability of ecological models by the car manufacturers , enlargement - even the content - the network of distributors, and by the growing attention of motorists to the economic and environmental benefits resulting from the use of such cars.
Compared to traditional gasoline and diesel, in fact, LPG and CNG fuels are cheaper. In particular, for the same mileage, the use of methane saves up to 65% compared to gasoline and up to 45% compared to diesel fuel, while LPG can save up to 50% compared to gasoline and up to 30% compared to a diesel engine. Not negligible are also economic benefits from lower vehicle operating costs due to elongation of the intervals that the use of these fuels can be obtained.
Extremely interesting are also beneficial for the environment. For their characteristics, natural gas and LPG are considered the cleanest fuel among those currently in use. In methane, in fact, as well as in GPL, are completely absent substances such as benzene, lead, particulate matter, sulfur compounds and polycyclic aromatic hydrocarbons, known carcinogens. Natural-gas engines also produce up to 80% fewer compound promoters of ozone (irritant to eyes and respiratory tract ¬ operators) and produces 21% less CO2 emissions compared to gasoline engines (- 10 % with LPG) and 11% less CO2 emissions than a diesel engine.
After observing the data, of course one wonders what are the reasons why the gasoline and diesel powered cars are still almost all (95%) of the Italian fleet. The main reason is surely represented by the presence of a network of LPG and CNG is not yet widespread, particularly as regards the latter (currently open only 756 of methane in plants across Italy, as against over 2500 distributors of GPL). The other reasons are also detectable in the reduced autonomy of gas cars, primarily those of methane (often overlooked), and in my opinion, in the prejudices that still exist on the safety and performance of the same.
In conclusion, notwithstanding the need for a strong and significant increase of the distribution of alternative fuels, it is imperative for increased and continued attention by all to environmental issues and sustainable mobility. The institutions in the first place must be the engine of change and the Municipality of Salento Fields can no longer avoid the use of vehicles with low environmental impact. There is no excuse: distributor of natural gas is located 4 kms from the city and several distributors of LPG are at a similar distance. The distances covered by municipal vehicles are not likely to create problems for autonomy. In addition, the savings achievable with alternative fuels is substantial and would allow funds of the City to breathe a small breath of fresh air (even healthy for our lungs). Unfortunately, so far you do not see signs of change in this regard. Quite the contrary. Our managers love the traditions and therefore the end of 2009 spend about € 13,700 to add to 18 vehicles existing (all strictly gasoline or diesel fuel and some of which are also obsolete) a brand new Fiat Punto Evo 1.4 petrol, in the face of ecology and saving!
