Is the German energy transition on track?
To reach climate neutrality in 2045, the German energy system needs to be transformed at an unprecedented pace. The Transformation Tracker takes a look at a variety of indicators for the progress of the energy transition (e.g. the number of e-cars or the share of renewables in the electricity mix) and compares actual data with target paths from the Ariadne scenarios.

How is the assessment done?
For each indicator, we measure the progress of the transformation. To do this, we set the actual development of the indicator - latest available value (current value) minus value in the reference year 2019 (reference value) - in relation to the development of the lead model in the Ariadne target path (model value) over the same time period.

Each indicator at a glance: How is the indicator developing? How does the corresponding target path in the Ariadne scenario compare to this? How is the current progress of the indicator assessed? Is it developing within the target corridor set out by all scenarios and models?
