Der hier vorliegende Report ist das Ergebnis des Teilprojekts "Transformation und Vernetzung städtischer Energieinfrastrukturen", welches Teil des "Rahmenprogramms zur Umsetzung der Energiewende in den Kommunen des Ruhrgebiets - Energiewende Ruhr" ist.
Die Transformation der Energieinfrastruktur, in einer Region die noch immer überwiegend auf zentrale Erzeugung und entsprechende Versorgungssysteme ausgerichtet sind, zählt zu den großen Herausforderungen einer gelungenen Energiewende - auch wenn nur ein Teil dieser Herausforderungen in der Region selbst beeinflusst werden kann.
Im Rahmen des Teilprojekts wurden zentrale technologisch-infrastrukturelle Herausforderungen im Kontext der Umsetzung der Energiewende im kommunalen Bereich analysiert. Insbesondere war hierbei von Interesse, wie das gezielte Vernetzen unterschiedlicher Infrastrukturbereiche (Strom, Wärme, Verkehr) einen Beitrag dazu leisten kann, Effizienzpotenziale zu heben und damit ein nachhaltiges und zukunftsfähiges Infrastruktursystem zu schaffen. Inhaltlich fokussierten die Analysen auf die Bereiche Kraft-Wärme-Kopplung (KWK) und Wasserstoff.
Bislang wurden solche mittel- und langfristigen Transformationsprozesse häufig allein durch technologiebezogene Szenarien und Strategien beschrieben. Der Ansatz erweist sich zunehmend als nicht zielführend, da er sich zu sehr auf einzelne Technologiebereiche beschränkt und das systemische Zusammenspiel zu wenig beleuchtet. Zudem werden weitere Faktoren (Nutzerverhalten, Investitionsentscheidungen, finanzielle Handlungsspielräume auf der Verbraucherseite, Akteursnetzwerke etc.) zumeist nur marginal betrachtet. Im Rahmen des Projekts wurde daher der methodische Zugang einer Cross-Impact-Bilanz gewählt, um diskursiv und partizipatorisch qualitative Zukunftsbilder für die Technologiebereiche zu entwerfen.
Technological breakthroughs and policy measures targeting energy efficiency and clean energy alone will not suffice to deliver Paris Agreement-compliant greenhouse gas emissions trajectories in the next decades. Strong cases have recently been made for acknowledging the decarbonisation potential lying in transforming linear economic models into closed-loop industrial ecosystems and in shifting lifestyle patterns towards this direction. This perspective highlights the research capacity needed to inform on the role and potential of the circular economy for climate change mitigation and to enhance the scientific capabilities to quantitatively explore their synergies and trade-offs. This begins with establishing conceptual and methodological bridges amongst the relevant and currently fragmented research communities, thereby allowing an interdisciplinary integration and assessment of circularity, decarbonisation, and sustainable development. Following similar calls for science in support of climate action, a transdisciplinary scientific agenda is needed to co-create the goals and scientific processes underpinning the transition pathways towards a circular, net-zero economy with representatives from policy, industry, and civil society. Here, it is argued that such integration of disciplines, methods, and communities can then lead to new and/or structurally enhanced quantitative systems models that better represent critical industrial value chains, consumption patterns, and mitigation technologies. This will be a crucial advancement towards assessing the material implications of, and the contribution of enhanced circularity performance to, mitigation pathways that are compatible with the temperature goals of the Paris Agreement and the transition to a circular economy.
Corporate energy and material efficiency ... makes good business sense : WISIONS of sustainability
(2006)
In this brochure, WISIONS focuses on corporate strategies for improving energy and material efficiency. WISIONS presents projects from Slovakia, Germany, the UK and Peru that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the projects was energy and resource efficiency, but social aspects were also of relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Will climate change stay below the 2 degree target in the 21st century on the basis of the COP 21 results? Looking into challenges and opportunities, this paper answers: To stay below the global 2dt is neither a real choice for the world society nor for businesses and civil societies in specific countries. It is a global guideline, scientifically developed for global negotiations, which should be broken down to national interests and actors. Key questions concerning the energy sector from the perspective of national interests are how to create and sustain a momentum for the inevitable energy transition, how to encourage disruptive innovations, avoid lock in effects, enable rapid deployment of energy efficiency and renewable energies etc. Or in other words: how to get to a competitive, economically benign, inclusive, low carbon and risk minimising energy system. With this background the paper argues that "burden sharing" is a misleading perception of strong climate mitigation strategies. It is more realistic to talk about "benefit sharing", using the monetary benefits and co-benefits of climate mitigation (e.g. energy cost savings, revenues from CO2-tax or emission trading systems) to help vulnerable national and international actors to adapt to the unavoidable climate risks. It has to be demonstrated on country level that the technologies and policy mix of strong climate mitigation and risk-minimising actions are indeed "benefit sharing" strategies which should be chosen anyhow, even if there was no climate change. For China and Germany this paper includes basic findings supporting this view.
This report was prepared by the Wuppertal Institute in cooperation with the German Economic Institute as part of the SCI4climate.NRW project. The report aims to shed light on the possible phenomenon that the availability and costs of "green" energy sources may become a relevant location factor for basic materials produced in a climate-neutral manner in the future.
For this purpose, we introduce the term "Renewables Pull". We define Renewables Pull as the initially hypothetical phenomenon of a shift of industrial production from one region to another as a result of different marginal costs of renewable energies (or of secondary energy sources or feedstocks based on renewable energies).
Shifts in industrial production in the sense of Renewables Pull can in principle be caused by differences in the stringency of climate policies in different countries, as in the case of Carbon Leakage. Unlike Carbon Leakage, however, Renewables Pull can also occur if similarly ambitious climate policies are implemented in different countries. This is because Renewables Pull is primarily determined by differences in the costs and availability of renewable energies. In addition, Renewables Pull can also be triggered by cost reductions of renewable energies and by changing preferences on the demand side towards climate-friendly products. Another important difference to Carbon Leakage is that the Renewables Pull effect does not necessarily counteract climate policy.
Similar to Carbon Leakage, it is to be expected that Renewables Pull could become relevant primarily for very energy-intensive products in basic materials industries. In these sectors (e.g. in the steel or chemical industry), there is also the possibility that relocations of specific energy-intensive parts of the production process could trigger domino effects. As a result, large parts of the value chains previously existing in a country or region could also be subjected to an (indirect) Renewables Pull effect.
For the federal state of NRW, in which the basic materials industry plays an important role, the possible emergence of Renewables Pull is associated with significant challenges as climate policy in Germany, the EU and also worldwide is expected to become more ambitious in the future.
This report aims to enable and initiate a deeper analysis of the potential future developments and challenges associated with the Renewables Pull effect. Thus, in the final chapter of the report, several research questions are formulated that can be answered in the further course of the SCI4climate.NRW project as well as in other research projects.
The German federal state of North Rhine-Westphalia (NRW) is home to important clusters of energy-intensive basic materials industries. 15% of the EU's primary steel as well as 15% of high-value base chemicals are produced here. Together with refinery fuels, cement, lime and paper production (also overrepresented in NRW) these are the most carbon-intensive production processes of the industrial metabolism. To achieve the ambitious regional and national climate goals without relocating these clusters, carbon-neutral production will have to become standard by mid-century. We develop and evaluate three conceptual long-term scenarios towards carbon-neutral industry systems for NRW for 2050 and beyond:
* a first scenario depending on carbon capture and storage or use for heavy industries (iCCS),
* a second scenario sketching the direct electrification of industrial processes (and transport) and
* a third scenario relying on the import of low carbon energies (e.g. biomass, and synthetic fuels (like methanol) for the use in industries and transport. All scenarios share the assumption that electricity generation will be CO2-neutral by 2050.
For all three scenarios energy efficiency, primary energy demand for energy services and feedstock as well as the carbon balance are quantified. We apply a spatial-explicit analysis of production sites to allow for discussion of infrastructure re-use and net investment needs. Possible symbiotic relations between sectors are also included. The robustness of the three conceptualised future carbon-neutral industry systems is then analysed using a multi-criteria approach, including e.g. energy security issues and lock-ins on the way to 2050.
In recent decades, better data and methods have become available for understanding the complex functioning of cities and their impacts on sustainability. This review synthesizes the recent developments in concepts and methods being used to measure the impacts of cities on environmental sustainability. It differentiates between a dominant trend in research literature that concentrates on the accounting and allocation of greenhouse gas emissions and energy use to cities and a reemergence of studies that focus on the direct and indirect material and resource flows in cities. The methodological approaches reviewed may consider cities as either producers or consumers, and all recognize that urban environmental impacts can be local, regional, or global. As well as giving an overview of the methodological debates, we examine the implications of the different approaches for policy and the challenges these approaches face in their application on the field.
Especially in the arid areas of the Middle East and North Africa (MENA), water availability plays an important role in the expansion planning of industrial-scale solar power plants. Although power plants may account for only a very small portion of local water demand, competition for water with other sectors is expected to increase when water resources are insufficient for meeting local needs. This can lead to conflicts between different users (such as communities, farmers, tourism, businesses and utilities). Despite the increasing attention on the water-energy nexus, comprehensive studies analysing the interdependencies and potential conflicts between energy and water at the local level are absent.
To examine the linkages between water resources and energy technologies at the local level, this case study was selected because Morocco is one of the countries most affected by water scarcity and, at the same time, it is also one of the most promising countries in North Africa for the development of renewable energies and offers excellent conditions for solar and wind power plants. Nevertheless, the country's electricity system is still largely based on conventional energy sources, and the country is more than 95% dependent on energy imports. To strengthen the country's energy security and reduce the financial burden associated with energy imports, Morocco is pursuing an ambitious renewable energy expansion strategy: by 2020, around 42% of the national electricity demand should be met by renewable energies. In view of Morocco's ambitious plans, it is particularly important to identify the potential conflicts and synergies resulting from the expansion of renewable energies in relation to the water sector.
