Abstract:
This paper suggests that a system dynamics approach is best suited to assess the sustainability of
technologies, with a specific emphasis on policy interventions for renewable energy in the African
context. A bioenergy technology sustainability assessment (BIOTSA) model is subsequently demonstrated
by analysing the outcomes of a proposed biodiesel production development on selected
sustainability indicators for the Eastern Cape Province of South Africa. In addition, some scenarios are
tested to compare how they may improve the selected indicators. The BIOTSA model results are useful
to compare dynamic consequences that may result from the proposed biodiesel production development
and the respective policies and decisions that may arise from such a development. Nevertheless,
recommendations are made to improve the usefulness and practicability of this type of model for
technology assessment purposes.
