Data
Open Energy Tracker
The Open Energy Tracker is an open platform for energy data that has been developed and maintained by DIW Berlin since 2022. It continuously collects and visualizes publicly available data on key technologies of the energy transition and selected market trends. Current trends are compared with key energy policy targets.
The data platform focuses on Germany, particularly at the federal level. Currently, data is provided on various technologies in the areas of renewable electricity, energy storage, renewable heat, electromobility, and hydrogen, as well as on energy consumption, greenhouse gas emissions, and energy prices. This data also forms the basis for the DIW Energiewende-Monitor.
In addition, selected data is also collected for France and Australia, which is updated at irregular intervals. Other countries may follow in the future.
The data and all scripts for its collection and visualization are made available open source under a free license. The data platform is available in German, English, and French.

DIW Energiewende-Monitor
Based on selected indicators from the Open Energy Tracker, the DIW Energiewende-Monitor provides an overview of the and trends in three key areas of the energy transition: renewable electricity, sector coupling and flexibility for the energy system. The focus is on developments over the past six months. The DIW Energiewende-Monitor is updated at least twice a year, typically in conjunction with a DIW Weekly Report.

Transport in Figures
“Transport in Figures” is the standard reference work on transport statistics in Germany. The transport statistics database “Transport in Figures,” compiled on behalf of the Federal Ministry of Transport (BMV) by the DLR Institute of Transport Research and DIW Berlin, has been published every fall for more than 50 years. It contains the latest figures and time series on all relevant topics in the fields of mobility and transportation. Until now, “Transportation in Figures” has been published as a paperback with a statistical appendix on CD-ROM and was available from the Federal Ministry of Transportation (BMV). Starting in 2027, the data will be published digitally.
The content ranges from annual figures on infrastructure investments to data on transport infrastructure, accidents, and traffic volume, as well as information on the mobility behavior of Germans, emissions, and a comparison with other European countries. Specifically, the contents are as follows.
-
Mode of transport used by the working population and schoolchildren
-
Length of transport routes, road area
-
Vehicle density, road load
-
Transportation expenditures, transport balance
-
Vehicle fleet, new registrations, mileage
-
Road traffic accidents
-
Cross-border traffic, transit
-
Passenger transport: volume and performance, purposes of travel
-
Freight transport: volume and performance
-
Freight rates, consumer price indices, cost trends
-
Energy consumption, environmental impact
Energy Balances
DIW Berlin was a founding member of the Working Group on Energy Balances (Arbeitsgemeinschaft Energiebilanzen e.V., AGEB) in 1971 and was involved in compiling the energy balances for the Federal Republic of Germany until 2023. The energy balances provide an overview of energy sector interdependencies in the form of a matrix. They provide data on the consumption of energy sources in the individual sectors and detail their flow from production to use across the various production, conversion, and consumption sectors. The energy balances are compiled by AGEB based on data from the Federal Statistical Office and industry associations. Among other things, they serve as a basis for determining energy-related greenhouse gas emissions. The final energy balance is published annually in February/March for the year before last (reporting year t-2). In addition, the AGEB compiles a so-called “preliminary energy balance” for the previous year (t-1) in June of each year.
