Riding an electric vehicles does not save the earth

Although talking about everything that is green is currently attracting attention, always attracting funds, and teasing the feelings of the public a lot, especially with regard to their future, which should be the color of pure green trees. However, the discussion went far beyond that to saving the planet, and the extent of your contribution to that by purchasing an electric vehicles.

And you can imagine sitting in your green cars – without carbon emissions – and the road on either side of it, recovering new types of trees and flowers that you revived as a result of riding an electric vehicle.
However, recent studies and analyzes point to shocking results in this regard.

Shocking results

An economic analysis said Tuesday, that electric vehicles are not always necessarily more environmentally friendly than other vehicles powered by internal combustion engines.

Reuters Analyst Paul Lennert from Detroit says that buying a new Model 3 electric vehicle from the American electric vehicle maker Tesla seems good in terms of its features and ride comfort, as well as for the planet, but he suddenly stopped to explain the following:

  • You need to drive 13,500 miles (21.725 km) before an electric vehicle is less environmentally harmful than a gasoline-powered vehicle. This is the result of a Reuters analysis of data from the Argon model, which calculates emissions over the life of a vehicle.
  • Developed by Argonne National Laboratory in Chicago, this model contains thousands of criteria, from the type of metal in an electric vehicle’s battery to the amount of aluminum and plastic in the vehicle.

This is an issue that draws attention as governments around the world work to promote environmentally friendly transportation to achieve their climate goals.

Carbon production

Argonne’s lead energy systems analyst, Jarrod Cole Kelly, says EVs produce more carbon than internal combustion engine vehicles, by extracting and processing minerals in EV batteries and producing power cells.

However, estimates of the size of the carbon gap when the vehicle is first sold, and where the “break-even point” will appear over the life of the electric vehicle, can vary greatly, depending on the assumptions.
According to Kelly, this duration depends on factors such as the size of the electric car’s battery, the fuel economy of petrol vehicles, and the method of electricity generation used to charge the electric vehicles.

Many answers, one question

The answers are increasing day by day to one question: Should I buy an electric vehicle in order to reduce carbon emissions and contribute to saving the planet?

Reuters came up with several answers by plugging in a set of variables into the Argonne model, which has more than 43,000 users as of 2021.

The Argonne model compared an electric vehicle to a gasoline-powered vehicle. The first is a Tesla Model 3, which works in the United States where 23% of the electricity comes from a coal-fired power plant, a 54 kWh battery, and a cathode (electrode) made of variables such as Nickel, cobalt and aluminium.

The second it competed was a 2,955-pound Toyota Corolla that was gasoline-powered with a fuel efficiency of 33 miles per gallon. Both vehicles were expected to drive 173,151 miles in their lifetime.

According to a Reuters analysis, a midsize electric saloon produces 47 grams of CO2 per mile during extraction and production, producing more than 8.1 million grams by the time it reaches its first customer. By comparison, a similar gasoline vehicle produces 32 grams per mile, or more than 5.5 million grams.

But if the same Tesla was running in Norway, which produces nearly all of its electric power from renewable hydropower, the break-even point would be just 8,400 miles away.

Analysis of data generated by Reuters shows that power plants for recharging electric vehicles come from coal, reaching the same level of carbon as a gasoline Toyota Corolla when most of the energy is produced in countries such as China and Poland. You must drive 78,700 miles. According to the Argonne model.

12 years

Electric vehicles typically emit less carbon over a 12-year lifespan, says Michael Wang, director of the Center for Systems Assessment in the Argonne National Laboratory’s Division of Energy Systems.

According to a Reuters analysis, even in a worst-case scenario where an electric vehicle is charged from only a coal-fired power plant, an additional 4.1 million grams of carbon is produced annually, and a gasoline-equivalent vehicle produces more than 4.6 million grams.

The ratio appears similar between the two vehicles, and the difference is the charging stations and how they depend on the generation source.

The results of the Reuters analysis are similar to those of the European automobile and internal combustion vehicle life cycle assessment conducted by research group IHS Markit.

The typical break-even point for carbon emissions varies from country to country, but some put it at around 20,000 miles, according to a survey.

The US Environmental Protection Agency said it has developed an online program that allows US consumers to estimate emissions from electric vehicles, based on the fuel used to generate electricity in the region.

Electric model vehicle

A typical electric vehicle would need to travel 700,000 kilometers before it emits less carbon dioxide than a similar petrol vehicle, said Damien Ernst, researcher at Li├Ęge University. But he later revised his numbers down.

It is currently estimated that the break-even point can be higher.
