The study What Will the Energy Transformation Cost? – Pathways for Transforming the German Energy System by 2050 also finds that a higher CO2 reduction target would dramatically increase the volume of renewable energy capacity necessary to provide sufficient power.
"Assuming that the price of fossil fuels remains constant up to 2050 and the penalties on carbon emissions remain low, simulations show that the extra costs for transforming the energy system based on the least expensive scenario are about €1.1trn
