Federal states can learn from one another in different areas of action
“With this fifth federal state comparison of renewable energy sources, we can make developments in the energy revolution comparable at a federal level and thus rate who is especially successful and where there are still potentials for optimization,” explained Professor Claudia Kemfert, head of the Department of Energy, Transportation, Environment at DIW Berlin. “The current study shows new highs for many indicators, for example with regard to the share of renewable energy in the federal states and a progressive expansion of various technologies. Generally, most states are on the right path, even if they are developing at different paces,” said Kemfert.
Baden-Württemberg leading, Mecklenburg Western Pomerania second
Baden-Württemberg received the most points overall, putting the state in the lead for the first time. Second place went to Mecklenburg Western Pomerania. Both states have improved by one position compared to the last ranking in 2014. The previous leader, Bavaria, received the third highest number of points.
Professor Frithjof Staiß, managing director of ZSW, commented on the results: “The variety of indicators enables us to classify each federal state's strengths and weaknesses in detail. The top three states alone are clearly different: Baden-Württemberg received a lot of points for its political input on the use of renewable energy. Mecklenburg Western Pomerania is strong in the field of structural change, and Bavaria continues to show high levels of expansion in the area of renewables.”
“However, not everything is bad in the Saarland just because it’s in last place, and nor is Baden-Württemberg leading in all areas and able to sit back and take it easy,” continued Staiß. “There is still potential to improve, for example in terms of using wind energy potential or economic indicators. In the latter area, however, the Saarland scores points for developing revenues with renewable technologies. In the indicator for solar energy storage, as well, this overall low-ranking federal state is at the top.”
A need for action, even with previous successes
While progress has been made in most of the individual indicators in all federal states, there are also developmental regressions in different areas, such as in the share of renewables in district heating or the development of energy-related CO2 emissions, in various states. Philipp Vohrer, the managing director of AEE, comments: “The transformation of the system is far from over, even where excellent ratings can be established. This study clearly demonstrates where there are misdevelopments and where there is a pressing need for action. There are potentials for improvement everywhere - you can look where each federal state scored highly and learn from them. Further efforts are needed, especially in the federal states, to successfully implement the energy transition and achieve climate goals.”
