Is the electric vehicle “going green”?
For several years, electric cars have been touted as a greener solution to reducing greenhouse gas emissions and fine particulate matter in the air. However, some experts argue that the electric car is simply a greening that does not solve environmental problems.
In order to determine whether electric vehicles are truly an environmental solution, this article will explore the question by examining their advantages and disadvantages.
Energy efficiency of electric vehicles
Electric vehicles are very efficient at converting energy into motion. Depending on the information provided, it may be converts 77% of electrical energy into kinetic energy. However, it should be noted that this efficiency depends on the energy source used to charge the batteries.
If 100% of the electricity used to charge electric vehicles comes from fossil fuels, the environmental impact of electric vehicles will be similar to that of combustion vehicles.
Advantages of electric cars in terms of energy consumption
Electric vehicle powertrains are more efficient than conventional car engines and transmissions. However, there are energy losses associated with the use of electrical accessories such as headlights, windshield wipers, navigation systems and entertainment systems. Moreover, electric vehicles use energy recovery during braking, which makes them more efficient in urban driving situations that thermal vehicles cannot do.
Environmental impact of battery production
The production of batteries for electric vehicles is an important point to consider when talking about their environmental impact. Batteries use rare materials and require large amounts of energy to produce. It is estimated that the production of an electric vehicle battery requires approx 150-200 GJ of energy (ie the equivalent of the annual consumption of a house) and It emits 150-200 kg of CO2.
In addition to the environmental impacts associated with battery manufacturing, there are the issue of availability of raw materials. Recent research suggests that there will likely be a shortage of lithium to support the growth of the electric vehicle market.
Alternatives to lithium-ion batteries, such as cobalt and nickel batteries, are being developed, but they also pose environmental risks, e.gresource depletion and impacts related to mining. Therefore, it is important to continue to research and develop more sustainable battery technologies as well as a proper recycling channel to reduce the environmental impact of electric vehicles.
Economic value of electric vehicles
Electric cars are more expensive to buy than conventional cars. However, the cost in use is generally lower due to savings in gasoline and mechanical maintenance. It’s important to consider these long-term costs when considering whether an electric car is an environmentally friendly solution. It should also be noted that the cost of electric vehicles is expected to decrease as technology and production improve.
Need for adequate infrastructure and renewable energy sources
For electric cars a an effective environmental alternative, the development of suitable charging infrastructure is crucial. In order for electric vehicles to function optimally, charging stations need to be easily accessible. It is therefore important that governments and companies invest in charging infrastructure to facilitate the transition to electric vehicles.
It is also important to note that achieving the Sustainable Development Goals also requires investment in renewable energy sources to power electric vehicles. Companies like Tesla have already started developing solutions that integrate renewable energy such as electric cars and solar panels into charging stations.
Solar energy and electric vehicles
There is strong growth in solar energy production worldwide, especially in China, India and the European Union. The cost of solar panels continues to drop, allowing electric vehicles to be charged when excess power is available on the grid, allowing for more efficient use of electrical resources.

The German startup has exactly that in mind Sound Engines developed If we, a family car completely covered in solar panels. It should be mass produced in the second half of 2023 distance 305 km and the final price was announced €25,000. This car is an example of an efficient combination of electric vehicles and solar energy.
At the end, electric vehicles have clear advantages in terms of energy efficiency and energy use. However, it is important consider the environmental impact and long-term economic costs of battery production. In addition, for electric vehicles to be a viable green solution, it is necessary to have adequate charging infrastructure and prioritize renewable energy sources.
In general, an electric car is a solution that can help reduce greenhouse gas emissions and fine particles in the airBut it should not be seen as a silver bullet. important for continue to explore and invest in other green technologies Achieving the Sustainable Development Goals.
