A new database of historical energy balances (PFUDB) has been developed by TNT’s Simon de Stercke in collaboration with Arnulf Grubler in order to
PFUDB covers data series over the period 1900 to 2010, thus adding important new information to the portfolio of historical data sets that are an important feature of TNT research.
By applying standard emission factors, the database also allows historical CO2 balances to be reconstructed by type of economic activity, for which previously long-run time series have not been available.
The historical data sets are used within TNT’s own research into the dynamics of change of large, complex systems. First research findings suggest that the traditional view of century-long time scales in technological transitions might be an artefact arising from input-derived measures, with an output-oriented perspective suggesting the possibility of much faster systems transitions. The new tool has generated considerable external interests with emerging collaborative research projects instituted with colleagues in China, Germany, and the USA.
The PFUDB adds to the portfolio of TNT online research tools of models and data bases with a particular emphasis on long-term systems transformations that has become a signature feature of TNT’s research and that constitutes an effective communication strategy to assure wide global dissemination with thousands of researchers reached (Figure 1). All online tools have been developed and are maintained by Peter Kolp.

Tools include the LSM2 model, and the ECDB (energy and carbon emissions inventories and their uncertainties), SD-ET (growth and scaling of energy technologies) and PFUDB (historical resource balances) data bases with historical data capturing major technological transitions that can be described using LSM2 (click on image to enlarge).
