3.3.8. Metro Energy Use per PKT

Metros are very often the least-energy-consuming mode in cities. Stockholm, the only Swedish city with a metro, consumes only 0.39 MJ/PKT, even a little lower than the European average of 0.42 and only a little higher than the Asian average of 0.34 MJ/PKT. Globally, metros average 0.52 MJ/PKT, but in the auto-dependent cities in the US, Australia and Canada, they average higher energy use (0.69, 0.75 and 0.64 MJ/PKT, respectively).

#### 3.3.9. Suburban Rail Energy Use per PKT

Suburban rail is generally the third least-energy-consumptive public-transport mode in cities, after metros and LRT. In Asian cities, however, suburban rail averages only 0.27 MJ/PKT. Swedish cities acquit themselves well here, by averaging 0.59 MJ/PKT (0.55 and 0.64 MJ/PKT in the larger and smaller cities, respectively). This is very like the other European cities (0.60) and Freiburg (0.65) and significantly better than the US and Canadian cities (1.29 and 1.17 MJ/PKT, respectively), due in no small part to the use of diesel fuel in some of their systems. In no case is suburban rail energy use more than that used in buses and is sometimes less than metros (e.g., in Linköping, Australian and Asian cities).
