Specific consumption

  • The specific energy consumption of the different modes of transport has been decreasing until 2019. However, there was an increase in 2020 and 2021, especially for public transport, due to lower occupancy rates.  
  • In 2019, cars required almost 2.2 times more energy per passenger-km than buses, and 7.3 times more than rail transport. Domestic air transport is more than twice more energy intensive than cars and 15 times more intensive than rail.
