Specific energy consumption by transport mode

The specific energy consumption of the different modes of transport has been decreasing or stable until 2019. However, there was an increase in 2020 and 2021, especially for public transport, due to lower occupancy rates. In 2022, it has almost returned to 2019 levels except for buses, whose specific energy consumption remains 26% higher than 2019 level.
In 2019, cars required almost 2.1 times more energy per passenger-km than buses, and 7.4 times more than rail transport. Domestic air transport is more than twice more energy intensive than cars and 16 times more intensive than rail.
