In October 2014, the European Council agreed on a target of improving overall energy efficiency by at least 27 per cent by 2030. According to the European Council's conclusions, this target should not be translated into nationally binding targets. Nevertheless individual Member States are free to set higher national objectives if desired. However, it is difficult to assess the degree of ambition of a national target because so far not much light has been shed upon the exact size of the untapped efficiency potentials.
This paper provides an in-depth analysis and comparison of existing studies on energy efficiency potentials in the European Union's (EU) Member States by 2030. It includes a structured overview of the results, information on the quality of the available data and suggestions for improvement.
The review shows that comprehensive studies on national energy efficiency potentials are rare and hardly comparable. The existing studies agree on the existence of significant potentials for energy efficiency. Their outcomes, however, vary significantly in terms of national levels. Assuming low policy intensity, energy savings between 10 and 28 per cent could be realised by 2030 compared to a baseline development, in the case of high policy intensity 7-44 per cent. Technical energy efficiency potentials in the different EU Member States are estimated at 14-52 per cent. On average, energy savings of 27 per cent by 2030 appear to be feasible with significant policy effort. We conclude that the deviation in Member States' energy efficiency potentials resulting from different studies represents an indication of the so far poor quality of underlying data. In order to allow for a concretisation of efficiency potential estimates, the comparability and detail of information sources should be improved.
Für die Energiewende in Deutschland ist zeitnah ein nennenswerter Ausbau der Stromnetze auf Transport- und Verteilnetzebene erforderlich. Mittel- bis langfristig werden für die Umstellung der Strom- und Energieversorgung auf erneuerbaren Energien (EE) zusätzlich große Speicherkapazitäten benötigt. Dabei sind kostengünstige und mit minimalen Energieverlusten verbundene Speicher- und Erzeugungstechnologien anzustreben. Lösungsansätze dafür werden bisher überwiegend auf der Stromseite diskutiert. Chancen, die sich aus der Kopplung von Strom- und Gasnetzen ergeben, werden kaum wahrgenommen. Das erhebliche Lösungspotential der vorhandenen Gasinfrastruktur und -Anwendungstechnologien mittels Power-to-Gas sowie die damit verbundenen Auswirkungen auf eine nachhaltige Gestaltung der Energiewende finden zu wenig Beachtung.
Vor diesem Hintergrund hatte das Forschungsvorhaben "Integration fluktuierender erneuerbarer Energien durch konvergente Nutzung von Strom und Gasnetzen - Konvergenz Strom- und Gasnetze" zum Ziel, unter Berücksichtigung der Kopplung von Strom- und Gasnetzen, (1) die Potenziale zur Aufnahme, Speicherung und Verteilung von EE zu bestimmen, (2) die dynamischen Energieströme aus Angebot und Nachfrage in der gesamten Energieversorgungsstruktur zu modellieren, (3) die Kopplung volkswirtschaftlich zu analysieren und (4) Handlungsempfehlungen für den Ausbau der Netzinfrastrukturen und die Entwicklung eines zukünftigen Energiemarktes abzuleiten.
In dem Forschungsprojekt "Technologien für die Energiewende" (TF_Energiewende) bewertet ein Konsortium von drei Verbundpartnern und zehn Technologiepartnern unter der Federführung des Wuppertal Instituts seit Herbst 2016 den mittelfristigen Forschungs- und Entwicklungsbedarf für die zentralen Technologien, die im Rahmen der Energiewende derzeit und zukünftig benötigt werden.
Der vorliegende Bericht ist Ergebnis eines zweijährigen Forschungsprojekts im Rahmen des Virtuellen Instituts "Transformation - Energiewende NRW". Das Projekt wurde von der Stiftung Mercator finanziert. Der Bericht beschäftigt sich in mehreren Schritten mit der Transformation des Energie- und Industrielandes NRW: Er analysiert die ökonomischen Effekte der Energiewende in NRW und arbeitet Erfolgsfaktoren sowie Gestaltungsmöglichkeiten für industrielle Transformationsprozesse heraus. Nachfolgend werden zentrale Ergebnisse dieser Analyseschritte knapp zusammengefasst.
The future belongs to the youth, but do they really have a say in it? Learning processes with regard to a successful socio-ecological change must start in childhood and adolescence in order to succeed in social transformation. The youth cannot be a passive part in a changing society - they have to be actively included in its design. When allowed to participate, young people can make important and effective contributions - which should not be reduced to sub-projects and opportunity structures. In a socio-political context, participation means involvement, collaboration, and commitment. In the context of intra- and inter-generational equity, as the core part of sustainable development, participation strategies should be developed that allow for a permanent and purposeful involvement of children and adolescents. Participation of young people is an important and appropriate step in strengthening those who are so strongly affected by the planning processes but are otherwise powerless. A successful involvement and participation of non-professional actors requires a target group-oriented method, a supportive culture of participation, as well as clarity and decision latitude. Abiding by these rules leads to central results.
Decarbonisation of energy systems requires deep structural change. The purpose of this research was to analyse the rates of change taking place in the energy systems of the European Union (EU), in the light of the EU's climate change mitigation objectives. Trends on indicators such as energy intensity and carbon intensity of energy were compared with decadal benchmarks derived from deep decarbonisation scenarios for the electricity, residential, transport, and industry sectors. The methodology applied provides a useful and informative approach to tracking decarbonisation of energy systems. The results show that the EU has made significant progress in decarbonising its energy systems. On a number of indicators assessed the results show that a significant acceleration from historical levels is required in order to reach the rates of change seen on the future benchmarks for deep decarbonisation. The methodology applied provides an example of how the research community and international organisations could complement the transparency mechanism developed by the Paris Agreement on climate change, to improve understanding of progress toward low-carbon energy systems.
