Global Model on Very Long Term Energy Environment.
VLEEM has been designed under a EU research project
to support R&D policy decisions in the field of
energy, in relation with sustainability objectives in
the very long term. Addressing energy and environment
issues over one century, VLEEM fills a gap in the existing
energy models which are designed and calibrated to address
much shorter time horizons.
The demand module of VLEEM, so called “BASES”,
addresses more specifically all issues related to energy
services and energy demand, with fundamental drivers
linked with demography, time-budgets and to information
embodied in technologies, organisations and skills.
The demand/supply technology module of VLEEM, so-called “TASES”, addresses more specifically all
issues related to the overall supply/demand equilibria
at regional and world levels on the very long term,
which meet sustainability criteria in the field of environment.
For policy and strategic purposes, VLEEM is used in
- First to produce pictures of sustainable world and
regional energy systems in the very long term (up
to 2100) corresponding to different technology paradigms.
- Second, to evaluate the trajectories between this
end-points and the present, and to identify key milestones
in R&D, industrial context, economic conditions
and social acceptability.
