Electric cars less environmentally friendly than diesel cars

Japanese company Mazda has limited the power of its first electric car, the MX-30, and installed a small battery on the car.

According to Autocar, this was done by the automaker specifically for several reasons, including increasing the environmental friendliness of the new electric car.

Explaining the need for restrictions, Mazda executives referred to a study at a Japanese university. According to this study, electric vehicles with 95 kilowatt-hour batteries in Europe will be less environmentally friendly than diesel cars. This is due to the peculiarity of generating electricity — a significant number of power plants are thermal.

It is assumed that an increase in the number of electric vehicles will increase the load on power plants. This in turn will lead to an increase in emissions of harmful substances, including soot, carbon dioxide and sulfur compounds.

It should be noted that experts have not yet agreed on the environmental friendliness of electric vehicles. In particular, in 2017, the Belgian research organization Transport & Environment conducted a study, which concluded that electric cars are in any case more environmentally friendly than cars with internal combustion engines.

Belgian researchers concluded that over the entire period of their existence, from production to disposal, electric cars, for example, in Poland, the country with the largest share of thermal power plants in the European Union, will still produce almost 25 percent less harmful emissions.

According to researchers, over the course of their entire life cycle, a diesel car emits an average of 206.1 grams of carbon dioxide per kilometer. For comparison, emissions of an electric car in Poland over the same period will amount to 159.1 grams per kilometer, and in Sweden — only 30 grams per kilometer. On average, an electric vehicle in the European Union will emit 89.1 grams of carbon dioxide per kilometer during its life cycle.

However, Mazda holds the view that when charging from thermal power plants, electric vehicles will be less environmentally friendly than diesel cars. At the same time, replacing the battery in the middle of the life of an electric vehicle will make it even less environmentally friendly.

To solve this problem, Mazda installed a rechargeable battery with a capacity of only 35.5 kilowatt-hours on the MX-30 electric car. For comparison, Tesla Model 3 electric cars, depending on the configuration, are equipped with batteries from 54 to 75 kilowatt-hours.

Mazda believes that it is precisely because of the small battery capacity that their MX-30 has the best mileage of 1 kilowatt-hour of battery capacity among electric vehicles. This, in particular, is achieved due to the small mass of the battery — less energy is consumed during acceleration.
