  This paper presents an assessment of global economic energy potentials for
all major natural energy resources. This work is based on both an extensive
literature review and calculations using natural resource assessment data.
Economic potentials are presented in the form of cost-supply curves, in terms
of energy flows for renewable energy sources, or fixed amounts for fossil and
nuclear resources, with strong emphasis on uncertainty, using a consistent
methodology that allow direct comparisons to be made. In order to interpolate
through available resource assessment data and associated uncertainty, a
theoretical framework and a computational methodology are given based on
statistical properties of different types of resources, justified empirically
by the data, and used throughout. This work aims to provide a global database
for natural energy resources ready to integrate into models of energy systems,
enabling to introduce at the same time uncertainty over natural resource
assessments. The supplementary material provides theoretical details and tables
of data and parameters that enable this extensive database to be adapted to a
variety of energy systems modelling frameworks.
