Energy transition: a super-model to guide policy makers

A team from the University of Geneva has modelled projections for the spread of green energy at local level. Switzerland will have to step up its efforts to achieve zero net carbon emissions by 2050.

However, these models have a number of limitations, including the fact that they are not very effective for generating projections on a regional scale. A team from the University of Geneva has designed a super-model to simulate the spread of three green technologies in Swiss municipalities by 2050. It is based on available statistics and combines twelve existing models of technology growth, while testing their relevance. The results, published in the journal PNAS Nexus , could help inform political decision-making.
