Zusammenfassung
This communication presents a first attempt at making a life cycle assessment of prospective electricity production
scenarios which were designed in the EnerGEO project. We start by a basic review of system (in this case, scenario)
modelling expectations in today s LCA study. We then review some of the challenges of implementation due to the
lack of detailed description of present and future electricity production systems. The importance of a detailed description
is then shown with an evaluation of uncertainty of life cycle impact assessment results for three scenarios
of German electricity production in 2030. The significant uncertainties we found, prevent us from detecting a relevant
trend or making any comparison between the three chosen scenarios. We finally come to the conclusion that the
LCA methodology will become relevant for the environmental assessment of electricity production scenarios when
many more detailed information are accounted to describe future technologies, structures and sources of energy.
