Der schnell fortschreitende Digitalisierungs- und Automatisierungsprozess ist heute schon ein wichtiger Wegbegleiter für die Transformation des aktuellen Energiesystems. Im vorliegenden Beitrag werden sechs Anwendungsbeispiele vorgestellt, die deutlich machen, dass die Energiewende ohne Digitalisierung nicht denkbar ist.
Today more than 45 % of all energy-related CO2 emissions come from burning coal. Thus, reducing CO2 emissions from coal use is a necessity for reaching the targets of the Paris Agreement. This will not only pose challenges for coal consumers (restructuring of the energy system), but also for countries whose economy is strongly depending on the production of coal. This paper examines the role of coal in three countries, which are or were in recent years among the top coal exporters: Indonesia, Colombia and Vietnam. Understanding challenges and possible transition pathways in these countries will help to develop global strategies to reduce CO2 emissions from coal in the short to mid-term.
In der Dissertation wird eine Methodik entwickelt, welche die Berechnung des Redispatcheinsatzes im deutschen Übertragungsnetz ermöglicht. Dabei wird die Auswirkungen einer Integration der Flexibilität aus dezentralen Anlagen in das elektrische Energiesystem dargestellt. Durch die Integration von dezentralen Flexibilitäten können geringere Brennstoff- und CO2-Zertifikatskosten bei relativ konstanten CO2-Emissionen erreicht werden. Bei einem Redispatcheinsatz, welcher die Leistungserhöhung aus konventionellen thermischen Kraftwerken weitgehend vermeidet, kann bei der Berücksichtigung dezentraler Flexibilitäten bis zu 99 Prozent der benötigten Redispatcherhöhung aus konventionellen Kraftwerken mit Hilfe dezentraler Alternativen ersetzt werden. Diese Übernahme der Redispatchaufgaben durch dezentrale Anlagen ist allerdings mit einer signifikanten Erhöhung der Redispatchkosten verbunden.
On 26 January 2019, the Commission on Growth, Structural Change and Employment recommended that no more coal-fired power plants would be operated in Germany by 2038 at the latest. In this paper the Wuppertal Institute comments on the results of the Commission and makes recommendations for the current necessary steps for the climate and innovation policy in Europe, Germany and North Rhine-Westphalia.
Research on sustainability transitions has expanded rapidly in the last ten years, diversified in terms of topics and geographical applications, and deepened with respect to theories and methods. This article provides an extensive review and an updated research agenda for the field, classified into nine main themes: understanding transitions; power, agency and politics; governing transitions; civil society, culture and social movements; businesses and industries; transitions in practice and everyday life; geography of transitions; ethical aspects; and methodologies. The review shows that the scope of sustainability transitions research has broadened and connections to established disciplines have grown stronger. At the same time, we see that the grand challenges related to sustainability remain unsolved, calling for continued efforts and an acceleration of ongoing transitions. Transition studies can play a key role in this regard by creating new perspectives, approaches and understanding and helping to move society in the direction of sustainability.
