Abstract: History of society is strongly influenced by the energy supply available and energy is an important economic production factor. It's coupled with extraction of natural ressources and the emission of pollutant particles and heat, surpassing the ability for regeneration of our ecosystems. Society has to face the question how to reduce energy demand. Transition engineering offers a roadmap for engineers how to re-focus the inventive and the facilitative intent of the professional engineers in every field to the problem of re-designing and re-developing all fossil fuel consuming systems to use less fuel. The goal is to “make things work” on long timescales and to offer feasible alternatives and a strong impetus towards change.
