Electric cars are still quite expensive and charging stations are not often found, but this kind of mobility offers an advantage that perhaps not many people know about. Given the recent increases in oil and therefore petrol, in fact, at the moment fully recharge an electric vehicle costs 14 times less in Italy than a full tank of petrol: 0,0084 against 0,1176 euros per kilometre. If we project the figure over a year considering an average distance traveled of 10 thousand kilometres, the savings for motorists exceed one thousand euros.
Attention, however: these calculations are valid only if the electric car is recharged using not the columns found in the city, but a domestic installation for the collection of solar energy. The numbers, in fact, are contained in a study carried out by the Norwegian company Otovo, which takes care of installing photovoltaic systems on the roofs of houses.
The analysis took into consideration seven countries and ours was the one in which the savings would be greater (the decisive factor, in the Italian case, is the tax burden on petrol, which provides for particularly heavy excise duties). “Follow the Spain, where solar energy has a cost of 12 times less than fossil fuel - reads the Otovo press release - while in France and Germany the ratio in favor of the electric car drops to 11. The ranking closes Poland, in which the saving of electric cars is 9 times higher than petrol and, on an equal footing, Norway e Sweden, where recharging is 8 times cheaper than a full tank of petrol”.
The study "confirms the role of energy self-consumption as a sustainable solution for the environment as well as a profitable one - says Fabio Stefanini, General Manager of Otovo Italia - The benefits become even more tangible by associating a storage system with the photovoltaic system, capable of store energy. Thus it can be taken when needed and, in the case of an electric vehicle, allows it to be recharged even in the hours without light".
