Alternative drives have an increasing share in the global, European and Polish market. The city authorities support primarily the de-velopment of electromobility. Progress in these issues is also noticeable in Poland. The increasing number of battery electric vehicles (BEVs) requires increasing energy costs of the country. Therefore, it is necessary to increase energy production. This work estimates how large this energy surplus should be. For this purpose, it was necessary to deter-mine the average energy consumption of an electric vehicle in real traffic conditions, and then to calculate the average energy demand for a selected number of vehicles. Obtained results were related to pollutant emission considered in the well-to-wheel perspective (in-cluding generation of electricity). In the article, the authors also referred to the minimum number of charging stations for electric vehicles on the Trans-European Transport Network (TEN-T) in Poland. This is a necessary condition on which depends the use of BEV vehicles not only on the territory of cities, but also throughout the country.
