A gasoline car must drop 4.6 liters to beat the electric in emissions

For gasoline vehicles emit less greenhouse gases than electric vehicles, the average global consumption of the former should be less than 4.6 liters per hundred kilometers (equivalent to 51 miles per gallon), according to a study released today by the University of Michigan (USA).

Washington, Nov 8 (EFE) .- For gasoline vehicles emit less greenhouse gases than electric vehicles, the global average consumption of the former should be less than 4.6 liters for every one hundred kilometers (equivalent to 51 miles per gallon), according to a study released today by the University of Michigan (USA).

Although they established this figure as an average level globally, the researchers pointed out that different ways of obtaining energy for electric vehicles cause levels to vary greatly depending on the country.

The study, conducted by Michael Sivak and Brandon Schoettle, is based on the comparison of emissions generated by cars powered by electricity and those they do it for fossil fuels in 143 countries.

"The reasons for carrying out a comparison of this type, country by country, is that the indirect emissions of the electric they depend on the mix of fuel sources used to generate electricity and countries differ widely in the fuel source combination, "Sivak said.

In Cuba, For example, the mark from which the consumption of gasoline should decrease so that emissions are lower than those of electric vehicles is 7.5 liters per hundred kilometers, far from the 4.2 The United States, the 3.5 from Argentina or the 2.9 from Spain.

At the other extreme is Paraguay, whose conditions set the efficiency ratio to be exceeded by 0.05 liters per hundred kilometers, four times less than Costa Rica, with 0.2.

To know the equivalents of the consumption values ​​by kilometers, they used data from various sources of electricity of the Union of Concerned Scientists and of the specific data of each country in terms of electric power production.

Regarding the analysis of electric cars, considered the emissions derived from the extraction and transport of raw materials to the electricity production plants, those from the burning of fuel in the generation of this energy, the losses during the distribution process and the efficiency of the ships.

In the case of gasoline, the extraction of crude oil, transportation and refinement of the same, as well as its subsequent delivery and combustion in the vehicle.

At work only the emissions and consequences of the driving itself are taken into account, but not those aspects derived from the manufacture of the own means of transport.
