Experts agree that the increasing demand for EV is going to result a significant reduce of globa oil use in approximately 5 years. Some EV antagonists often say that the electric cars, batteries and energy production generates even more pollution than cars with internal-combustion engines. The Institute of Energy-Efficient Technologies director Vladimir Sidorovich tells why such statement is far from true. Read further for main insights of his opinion with supporting facts.


Electricity in terms of the final product in this case is ecologically clean

Electric vehicles do not produce any kind of greenhouse emissions. It means that a widespread use of EVs will reduce the amount of pollution in big cities.


Opposite opinion claims that the ‘carbon footprint’ of EVs is many times higher than the amount of gas occuring from internal combustion vehicles due to the ‘dirty’ energy production.

Indeed, natural gas and coal (which is the biggest source of greenhouse gas) are the main energy sources for the electricity production. A popular conclusion out of this fact suggests that the increasing number of electric vehicles would obviously result the electric energy production increase, that would have a harmful effect on atmosphere. However, according to the expert’s view, even if we admire that in some region all electricity is being produced only from coal, electric vehicles would whatever be better for ecology in cities. The thing is that the exhaust fumes accumulate near the ground surface – right in the air we breathe. However, powerplant’s tubes are always high enough to enlarge the emissions dispersion area making far lower concentration of those by the ground.


In reality, electric vehicle carbon footprint is even smaller because of various energy sources.

Moreover, the wider use of sustainable energy cuts the footprint even more till the zero in case when 100% of energy in the country comes from renewable sources. For example, Norway (that is actually leading in terms of EVs for 1 citizen) gets most of its energy from hydropower.


PJSC ‘MOESK’ (Moscow United Electric Grid Company) conducted the independent research of the impact EVs have on air in one of the most polluted cities on Earth – Moscow. The result of estimations showed far less pollution from electric vehicle than from internal combustion one considering all activities of energy and gasoline production: CO2 emission made by Mitsubishi i-MiEV is 2,2 times less than the same of Mitsubishi Colt with 1,1 litre engine with 70 hp.


Electric cars are better for the ecology even considering the batteries production, as well as the vehicles production and utilization.

The Union of Concerned Scientists in USA have also conducted a research estimating the carbon footprint of electric vehicles considering the extraction, transportation and processing the raw materials, the delivery of energy to consumers and the efficiency of the vehicles using various types of fuel. The work concluded ecological preference of electric vehicles in any state of North America, even though natural gas and coal still take 33% in energy structure. Final amount of CO2 produced by an EV equals 154 grams per mile, while the gasoline-powered cars produce about 381 grams per mile on average. EVs are even more advantageous in states with higher part of sustainable energy. Furthermore, even though electric batteries manufacturing is still quite energy-consuming, their part in total pollution is very low throughout the EV lifetime.


Electric vehicles are going to become ‘greener’ in the nearest future

And that would be a result of rising sustainable sources in the world energy balance. Dynamic green energy development is already spotted – wind and solar energy production part increases, while the coal burning drops significantly. For instance, coal share in USA decreased from 49% in 2006 to 33%, UK plans to refuse the coal production completely by 2025, followed by China. All of these means rising EVs advantages over internal combustion from year to year.
