Ein CO2-Preis ist ein zentrales Instrument, um eine umfassende Dekarbonisierung der Wirtschaft zu ermöglichen und zu erleichtern. Sie kann durch verschiedene Instrumente umgesetzt werden, insbesondere in Form einer CO2-Steuer. Es ist jedoch wichtig, dass ein CO2-Preis allein - aufgrund der vielfältigen Hindernisse (einschließlich nicht ökonomischer Hemmnisse) - die sektoralen Ziele und Instrumente nicht ersetzen kann. Vielmehr muss er komplementär zu sektorspezifischen Klimaschutzinstrumenten eingeführt werden. Der Artikel gibt Auskunft darüber, wie ein CO2-Preis konkret und angemessen ausgestaltet werden kann.
Derzeit befindet sich der zweite Entwurf zum Gebäudeenergiegesetz (GEG) des Bundeswirtschaftsministeriums und Bundesbauressorts zur Vereinheitlichung des Energieeinsparrechts für Gebäude in den Ressorts in der Abstimmung. Doch der Entwurf fällt weit hinter dem aktuellen klimapolitischen Aufbruch der Großen Koalition zurück und die Vorgaben der Europäischen Union erfüllt er nicht.
A significant reduction in greenhouse gas emissions will be necessary in the coming decades to enable the global community to avoid the most dangerous consequences of man-made global warming. This fact is reflected in Germany's 7th Federal Energy Research Program (EFP), which was adopted in 2018. Direct Air Capture (DAC) technologies used to absorb carbon dioxide (CO2) from the atmosphere comprise one way to achieve these reductions in greenhouse gases. DAC has been identified as a technology (group) for which there are still major technology gaps. The intention of this article is to explore the potential role of DAC for the EFP by using a multi-dimensional analysis showing the technology's possible contributions to the German government's energy and climate policy goals and to German industry's global reputation in the field of modern energy technologies, as well as the possibilities of integrating DAC into the existing energy system. The results show that the future role of DAC is affected by a variety of uncertainty factors. The technology is still in an early stage of development and has yet to prove its large-scale technical feasibility, as well as its economic viability. The results of the multi-dimensional evaluation, as well as the need for further technological development, integrated assessment, and systems-level analyses, justify the inclusion of DAC technology in national energy research programs like the EFP.
Weltweit trägt die Industrie direkt und indirekt etwa über ihren Bezug von Strom und Wärme rund 30 bis 40 Prozent zu den Treibhausgasemissionen bei. Auch in Deutschland liegt ihr Beitrag in einer ähnlichen Größenordnung1. Dabei sind insbesondere die Grundstoffindustrien (Stahl, Zement, Grundstoffchemie, Glas, Aluminium, Papier und andere) besonders energie- und emissionsintensiv. Gleichzeitig basiert der Energieeinsatz dieser Industrien bisher noch überwiegend auf fossilen Energien (und Müll). Zu den energiebedingten Emissionen kommen prozessbedingte Emissionen hinzu, die sich bei den heute üblichen Verfahren selbst bei Einsatz vollständig "grüner" Energien nicht vermeiden lassen. Grundstoffindustrien stellen Materialien für die Herstellung und Verarbeitung von Produkten zur Verfügung. Sie sind daher kein Selbstzweck, sondern tragen letztlich damit dazu bei, vielfältige Bedürfnisse abzudecken.
German energy transition : targets, current status, chances and challenges of an ambitious pathway
(2019)
With the "Energiewende", the German term for the transformation of the national energy system, the German government pursues ambitious goals, primarily but not only to reflect the climate change challenge and to react to the risks associated with the use of nuclear power plants. After launching the energy concept in mid-2011, which describes the "Energiewende" goals, Germany was perceived as an international pioneer in energy transition for many years and has been acknowledged for its braveness to combine ambitious greenhouse gas (GHG) mitigation targets with a phase out program for nuclear power plants. In this context, this article asks where Germany’s energy transition currently stands, what is planned next and how far the set targets have been achieved or where more action is required to stick to this pathway.
Im Energiesektor hat die Digitalisierung bereits viele Abläufe der Wertschöpfungskette verändert. Es besteht jedoch weiterhin erhebliches Potenzial zur Nutzung von digitalen Anwendungen. Insofern ist mit weiteren tiefgreifenden Veränderungen zu rechnen. Neben den zahlreichen Nutzen bestehen auch potenzielle negative Auswirkungen. Die so entstehenden Spannungsfelder müssen frühzeitig analysiert werden, um Lösungsoptionen für potenzielle Hindernisse zu erarbeiten um somit den größtmöglichen Nutzen der Digitalisierung erzielen zu können.
In recent years, most countries in the Middle East and North Africa (MENA), including Jordan, Morocco and Tunisia, have rolled out national policies with the goal of decarbonising their economies. Energy policy goals in these countries have been characterised by expanding the deployment of renewable energy technologies in the electricity mix in the medium term (i.e., until 2030). This tacitly signals a transformation of socio-technical systems by 2030 and beyond. Nevertheless, how these policy objectives actually translate into future scenarios that can also take into account a long-term perspective up to 2050 and correspond to local preferences remains largely understudied. This paper aims to fill this gap by identifying the most widely preferred long-term electricity scenarios for Jordan, Morocco and Tunisia. During a series of two-day workshops (one in each country), the research team, along with local stakeholders, adopted a participatory approach to develop multiple 2050 electricity scenarios, which enabled electricity pathways to be modelled using Renewable Energy Pathway Simulation System GIS (renpassG!S). We subsequently used the Analytical Hierarchy Process (AHP) within a Multi-Criteria Analysis (MCA) to capture local preferences. The empirical findings show that local stakeholders in all three countries preferred electricity scenarios mainly or even exclusively based on renewables. The findings demonstrate a clear preference for renewable energies and show that useful insights can be generated using participatory approaches to energy planning.
Urban energy systems have been commonly considered to be socio-technical systems within the boundaries of an urban area. However, recent literature challenges this notion in that it urges researchers to look at the wider interactions and influences of urban energy systems wherein the socio-technical sphere is expanded to political, environmental and economic realms as well. In addition to the inter-sectoral linkages, the diverse agents and multilevel governance trends of energy sustainability in the dynamic environment of cities make the urban energy landscape a complex one. There is a strong case then for establishing a new conceptualisation of urban energy systems that builds upon these contemporary understandings of such systems. We argue that the complex systems approach can be suitable for this. In this paper, we propose a pilot framework for understanding urban energy systems using complex systems theory as an integrating plane. We review the multiple streams of urban energy literature to identify the contemporary discussions and construct this framework that can serve as a common ontological understanding for the different scholarships studying urban energy systems. We conclude the paper by highlighting the ways in which the framework can serve some of the relevant communities.
