Energy efficiency of a range of domestic appliances covered by the labelling and ecodesign directives has improved significantly over the last 15 years. However, the power consumption of the German residential sector has remained relatively constant over this period. Besides other factors, such as decreasing average household size, the main reasons for this development were the increases of the types, features, size, equipment stock and usage times of appliances and devices in private households.
The project "Energy Sufficiency - strategies and instruments for a technical, systemic and cultural transformation towards sustainable restriction of energy demand in the field of construction and everyday life" investigates how the complementation of energy efficiency with energy sufficiency could lead to more user adequate domestic products and product-service systems and thereby result in an absolute reduction of power consumption.
In this project, energy sufficiency is defined as a strategy to reduce energy consumption by three approaches:
1. Quantitative reduction of sizes, features, usage times of devices etc.
2. Substitution of technical equipment in households by e.g.urban services.
3. Adjustment of technical services delivered by appliances toutility needed and desired by users.
The energy saving effects of an application of these approaches were modelled for different types of households and the energy saving potentials of energy sufficiency quantified. Innovative approaches for user adequate products and services were developed in open innovation workshops by the Design Thinking method. The paper summarizes some of the intermediate results of theoretical and transdisciplinary investigations of the project that runs until May 31, 2016. Furthermore, a first set of design criteria for user adequate appliances enabling energy sufficiency are developed based on these results. The paper concludes with suggestions for the future development of energy labelling and ecodesign derived from the design criteria and supplemented by examples of existing requirements according to the voluntary environmental label "Blauer Engel".
The paper presents the results of an ex-ante evaluation of the economy-wide benefits that may be achieved through the implementation of the 20-year Energy Efficiency Action Plan (EEAP) in Thailand. The objective of the EEAP is to reduce energy intensity by 25 % in 2030 compared to 2010. This is to be reached by reducing the projected energy consumption by 20 % or 38 Mtoe until 2030. We have specified an analytical framework, which allows for a calculation of the overall energy cost savings, energy import cost reductions and reduced CO2 emissions. Moreover, we calculated the induced energy efficiency investments, employment effects and impacts on governmental budget. The evaluation shows that an effective implementation of the plan may lead to a reduction in energy expenditure of 37.7 billion EUR by 2030. Moreover, the EEAP-induced energy savings will significantly reduce the greenhouse gas emissions as well as Thailand’s energy import costs and generate private investment in energy efficiency of about 5 billion EUR annually in 2030, which in turn may lead to about 300,000 new jobs. The size of the net impact of the plan on Thailand’s governmental budget is uncertain due to positive and negative effects on corporate and income tax revenues, expenses for unemployment benefits, governmental energy consumption, expenses for energy subsidies and energy tax income.
Die Energiewende in Deutschland ist ein seit Jahren viel diskutiertes Thema. Neben dem Wandel der Energieerzeugungssysteme hin zu regenerativen Energiequellen muss auch eine Steigerung der Energieeffizienz stattfinden. Nur durch Adaption beider Seiten der Erzeugung als auch des Verbrauchs, lassen sich die Herausforderungen meistern.
Energieeffizienz weltweit : energieeffiziente Gebäude als Schlüssel für eine nachhaltige Entwicklung
(2015)
Rund ein Drittel der weltweiten energiebezogenen CO2-Emissionen sind auf den Verbrauch durch Gebäude zurückzuführen. Ohne eine sogenannte Gebäudewende sind die notwendigen CO2-Einsparungen nicht zu ereichen. Eine Internetplattform bündelt das weit verstreute Wissen zu diesem Thema und bietet Orientierung.
Estimating the sufficiency potential in buildings : the space between underdimensioned and oversized
(2019)
The emission reduction potential of energy efficiency and energy supply in buildings is estimated in various energy and climate action plans, scenarios, and potential analyses. But the third pillar of sustainability - sufficiency - is neglected in most studies.The increasing demand of space per person in the residential sector is a trend in most European countries. Its implication on energy use, demand for resources like land, building material, equipment, and waste production is enormous. Next to the ecological impact, the distribution of space has social and societal effects. Thus, sufficiency policies in the building sector complementing efficiency and energy policy are needed for a sustainable development of the European building stock.
But how can a sufficiency potential in the building sector be estimated? How much space and equipment is needed for a decent living and how much is too much? The paper proposes four areas of sufficiency in buildings: space, design and construction, equipment, and use. It presents a set of indicators, a quantitative estimate of energy savings from reduced per capita floor area, and visualises the sufficiency potential in European countries in an experimental approach. The final discussion focuses on the question: What does this mean for policy making?
In spite of differences in energy policies and supply, Japan and Germany have to master similar challenges: To reorganize the energy supply system towards - in the long term - being reliable, affordable, low in risks and resource use, and climate-neutral. At the same time, the ecological modernization should maintain or even strengthen international competitiveness. To better address these challenges, a bi-national expert council has been established between the two high-tech countries in 2016 - the GJETC.
The aim of the GJETC is to show that despite different starting points, a national energy transition can be more successful, if both countries learn from their strengths and also weaknesses, to avoid the latter. If the implementation of an energy transition in the two countries is socially and economically sound and advances technology innovation and deployment, it may not only double success, but can also serve as blue prints for other countries, especially due to learning from similarities and differences. For example: Why is per capita energy consumption higher in transport in Germany, but energy intensity higher in Japan's building sector? How can variable renewable energies be integrated in an efficient energy system at lowest costs?
The Council meets twice a year, holds stakeholder dialogues and outreach events, and prepares policy papers on strategic topics of mutual interest. Four comprehensive studies, each in cooperation of a German and a Japanese research institute, have been the basis for 15 joint key recommendations during the 1st phase. The 2nd phase to 2020 will study the role of hydrogen and digitalisation for the energy transition, as well as other topics. The paper presents the findings and recommendations of the GJETC of the first phase 2016-18 as well as first results of the second phase. It also reviews the setup of the GJETC and the way it works, to assess if and how it can serve as a role model of bilateral cooperation on the energy transition.
Dieses Wuppertal Paper dient dazu, a) die mögliche Klimaschutzwirkung eines CO2-Preises zu analysieren, allein und im Gesamtpaket von Instrumenten zum Klimaschutz, b) die Möglichkeiten der Mittelverwendung zu analysieren und zu bewerten, c) dadurch den Dschungel der Argumente und Motivationen in den bestehenden Vorschlägen zu lichten und d) aus der Analyse ein Modell zu skizzieren, das den Anforderungen von Klimaschutz und sozialer Gerechtigkeit sowie Erhalt der Wettbewerbsfähigkeit am besten gerecht wird und damit der Bundesregierung als Anregung bei der Entscheidung über Einführung und Ausgestaltung eines CO2-Preises dienen kann.
In dem Papier werden diese Fragen anhand von neun Thesen mit einem abschließenden Fazit ergründet. Daraus wird deutlich:
Ein CO2-Preis kann sektorale Ziele und Instrumente nicht ersetzen. Seine volle Wirkung kann er nur entfalten, wenn er komplementär zu sektorspezifischen Klimaschutzinstrumenten eingeführt wird. Nur wenn für diese Instrumente ein guter Teil der Einnahmen aus der CO2-Steuer eingesetzt wird, sind die Klimaziele erreichbar. Die Ziele werden dadurch mit weitaus geringerem CO2-Preis bei gleichzeitig höheren Kostenentlastungen für Verbraucherinnen und Verbraucher, Unternehmen und sogar die öffentlichen Haushalte erreichbar, als wenn die Politik allein auf einen CO2-Preis setzen würde.
Die Wirtschaftsleistung von Deutschland ist durch die Corona-Pandemie stark beeinträchtigt. Um die Wirtschaft zu beleben, einigten sich die Regierungsparteien am 3. Juni 2020 in ihrem Koalitionsausschuss auf ein "Konjunktur- und Krisenbewältigungspaket" sowie ein "Zukunftspaket" in Höhe von insgesamt 130 Milliarden Euro. Für 2020 und 2021 sind fast 60 Maßnahmen vorgesehen, die von steuerlichen Vergünstigungen bei der Mehrwertsteuer bis hin zu konkreten Investitionen in Zukunftstechnologien reichen. Mit Blick auf den Klimaschutz beinhaltet das Maßnahmenpaket der Großen Koalition zwar gute Ansätze und viele wichtige Impulse, die allerdings zu verpuffen drohen, wenn sie nicht durch eine konsequente und nachhaltig ausgerichtete Klimapolitik flankiert werden. Zudem fehlen für den Klimaschutz wichtige Bereiche, wie Investitionen in die Kreislaufwirtschaft. Außerdem werden Maßnahmen zur Steigerung der Energieeffizienz nur unzureichend berücksichtigt. Gerade in diesen Bereichen hätten sich konjunkturbelebende Effekte und Klimaschutz in idealer Form ergänzen können, kritisiert das Wuppertal Institut. Dieses Diskussionspapier reagiert auf die vorliegenden Vorschläge und fasst zusammen, welche Maßnahmen im Rahmen der jetzt anstehenden Umsetzungsphase nachgebessert werden sollten und wo Ergänzungen notwendig sind.
