Technacy predicts that a change in one part of the technological dynamic creates or forces a shift in the other elements. So, if a change in the Eco-resource is forced upon a technology system both the; tools instuments and devices and The Knowledge, values and organisation of Agency must necessarily experience a shift and adaptation.
The video below cited on a Post Carbon institute site article, discusses oil as a dominating eco-resource. Special mention is made of the way trade [a purpsoe.context factor] is organised, operated and fuelled [ie. the economy]. If our whole technological civilization is fueled on oil, and oil becomes more and more expensive- what can we expect to give in the agency, tools, instruments devices, and what purpose/context factors need to be re-evaluated.
