Japan 2012

Moving from principles to action for energy supply that mitigates against climate change requires a long-term perspective. Energy infrastructure takes time to build up; new energy technologies take time to develop. Policy shifts often also need many years to take effect. In most world regions the transformation from fossil to renewable energies will require additional investment and higher supply costs over about twenty years

1.8 japan: transport

In the transport sector, it is assumed under the Energy [R]evolution scenario that an energy demand reduction of 1,791 PJ/a can be achieved by 2050, saving 50% compared to the Reference scenario. This reduction can be achieved by the introduction of highly efficient vehicles, by shifting the transport of goods from road to rail and by changes in mobility-related behaviour patterns. Implementing attractive alternatives to individual cars, the car stock is growing slower than in the Reference scenario.

A shift towards smaller cars triggered by economic incentives together with a significant shift in propulsion technology towards electrified power trains and a reduction of vehicle kilometres travelled by 0.25% per year leads to significant final energy savings. In 2030, electricity will provide 8% of the transport sector’s total energy demand in the Energy [R]evolution, while in the advanced case the share will be 16% in 2030 and 49% by 2050.
