In der Ausgabe Politisches Lernen 1-2|2019 setzte sich Kurt P. Tudyka mit dem Verhältnis von Theater und Politik auseinander. Er gelangte zu dem ernüchternden Resümee: „Der Anspruch, Theater sei die Schule der Nation, – soweit er überhaupt noch besteht –, müsste aufgegeben werden.“ (S. 32) In Tudykas Einführung hieß es bereits: „Eine politisierende Wirkung auf das Publikum wird bestritten.“ (S. 30) Vor diesem Hintergrund könnte bei Lehrerinnen und Lehrern der Politischen Bildung der Eindruck entstehen, ein Besuch im Theater mit Schülerinnen und Schülern sei didaktisch nicht sinnvoll. Dagegen wird im folgenden Beitrag die Auffassung vertreten, dass ein Theaterbesuch mit den Lernenden durchaus mit Erkenntnisgewinnen, seien sie politisch oder über das Politische hinausweisend, verbunden sein kann. Der Beitrag stellt eine gekürzte Fassung des Textes „Theater und politische Bildung“ dar, der in Markus Gloe / Tonio Oeftering (Hrsg.): Politische Bildung meets Kulturelle Bildung, Baden-Baden (Nomos) 2020, erscheinen wird.
Eigentlich leben wir heute im Holozän, dem Erdzeitalter, das mit dem Ende der letzten großen Eiszeit vor etwa 12.000 Jahren seinen Ausgang nahm. Doch seit geraumer Zeit ist in Wissenschaft und Öffentlichkeit die Rede vom Anthropozän als der vom Menschen bestimmten gegenwärtigen Epoche. Mit der Begriffsschöpfung soll der gravierende Einfluss des Menschen auf die Umwelt zum Ausdruck gebracht werden, der sich nicht zuletzt in der Versauerung der Meere, im Artensterben und Klimawandel äußert. Doch wie spiegelt sich diese Erkenntnis in der Politischen Bildung wider?
Zur Jahreswende 1959/60 sorgten Hakenkreuzschmierereien an jüdischen Einrichtungen in Köln und anderswo für Entsetzen und Empörung. Diese Vorkommnisse machten bewusst, was im Verlauf der 1960er Jahre zu einem Politikum für die jüngere Generation werden sollte: Die mangelnde Aufarbeitung der nationalsozialistischen Vergangenheit. Diese Thematik sowie der von den USA in Vietnam geführte Krieg stellten mobilisierende Faktoren für die Herausbildung einer außerparlamentarischen Opposition (APO) in der Bundesrepublik dar, die sich in der zweiten Hälfte der 1960er Jahre verbreitert. Prof. Ingo Juchler beschreibt den Weg der Politischen Bildung durch die 60er Jahre und die Entwicklung hin zur sog. „didaktischen Wende“.
Using a novel agent-based model, we study how US withdrawal might influence the political process established by the Paris Agreement, and hence the prospects for reaching the collective goal to limit warming below 2 degrees C. Our model enables us to analyze to what extent reaching this goal despite US withdrawal would place more stringent requirements on other core elements of the Paris cooperation process. We find, first, that the effect of a US withdrawal depends critically on the extent to which member countries reciprocate others' promises and contributions. Second, while the 2 degrees C goal will likely be reached only under a very small set of conditions in any event, even temporary US withdrawal will further narrow this set significantly. Reaching this goal will then require other countries to step up their ambition at the first opportunity and to comply nearly 100% with their pledges, while maintaining high confidence in the Paris Agreements institutions. Third, although a US withdrawal will first primarily affect the United States' own emissions, it will eventually prove even more detrimental to other countries' emissions.
Understanding and accounting for the effect of exchange rate fluctuations on global learning rates
(2020)
Learning rates are a central concept in energy system models and integrated assessment models, as they allow researchers to project the future costs of new technologies and to optimize energy system costs. Here we argue that exchange rate fluctuations are an important, but thus far overlooked, determinant of the learning-rate variance observed in the literature. We explore how empirically observed global learning rates depend on where technologies are installed and which currency is used to calculate the learning rate. Using global data of large-scale photovoltaic (>= 5 MW) plants, we show that the currency choice can result in learning-rate differences of up to 16 percentage points. We then introduce an adjustment factor to correct for the effect of exchange rate and market focus fluctuations and discuss the implications of our findings for innovation scholars, energy modellers and decision makers. <br /> Learning rates are a measure of reduction in costs of energy from technologies such as solar photovoltaics. These are often estimated internationally with all monetary figures converted to a single currency, often US dollars. Lilliestam et al. show that such conversions can significantly affect the learning rate estimates.
The European potential for renewable electricity is sufficient to enable fully renewable supply on different scales, from self-sufficient, subnational regions to an interconnected continent. We not only show that a continental-scale system is the cheapest, but also that systems on the national scale and below are possible at cost penalties of 20% or less. Transmission is key to low cost, but it is not necessary to vastly expand the transmission system. When electricity is transmitted only to balance fluctuations, the transmission grid size is comparable to today's, albeit with expanded cross-border capacities. The largest differences across scales concern land use and thus social acceptance: in the continental system, generation capacity is concentrated on the European periphery, where the best resources are. Regional systems, in contrast, have more dispersed generation. The key trade-off is therefore not between geographic scale and cost, but between scale and the spatial distribution of required generation and transmission infrastructure.
The history of concentrating solar power (CSP) is characterized by a boom-bust pattern caused by policy support changes. Following the 2014-2016 bust phase, the combination of Chinese support and several low-cost projects triggered a new boom phase. We investigate the near- to mid-term cost, industry, market and policy outlook for the global CSP sector and show that CSP costs have decreased strongly and approach cost-competitiveness with new conventional generation. Industry has been strengthened through the entry of numerous new companies. However, the project pipeline is thin: no project broke ground in 2019 and only four projects are under construction in 2020. The only remaining large support scheme, in China, has been canceled. Without additional support soon creating a new market, the value chain may collapse and recent cost and technological advances may be undone. If policy support is renewed, however, the global CSP sector is prepared for a bright future.
In order to achieve the temperature goals of the Paris Agreement, the world must reach net-zero carbon emissions around mid-century, which calls for an entirely new energy system. Carbon pricing, in the shape of taxes or emissions trading schemes, is often seen as the main, or only, necessary climate policy instrument, based on theoretical expectations that this would promote innovation and diffusion of the new technologies necessary for full decarbonization. Here, we review the empirical knowledge available in academic ex-post analyses of the effectiveness of existing, comparatively high-price carbon pricing schemes in the European Union, New Zealand, British Columbia, and the Nordic countries. Some articles find short-term operational effects, especially fuel switching in existing assets, but no article finds mentionable effects on technological change. Critically, all articles examining the effects on zero-carbon investment found that existing carbon pricing scheme have had no effect at all. We conclude that the effectiveness of carbon pricing in stimulating innovation and zero-carbon investment remains a theoretical argument. So far, there is no empirical evidence of its effectiveness in promoting the technological change necessary for full decarbonization.

Friends or foes?
(2020)
Energy efficiency measures and the deployment of renewable energy are commonly presented as two sides of the same coin-as necessary and synergistic measures to decarbonize energy systems and reach the temperature goals of the Paris Agreement. Here, we quantitatively investigate the policies and performances of the EU Member States to see whether renewables and energy efficiency policies are politically synergistic or if they rather compete for political attention and resources. We find that Member States, especially the ones perceived as climate leaders, tend to prioritize renewables over energy efficiency in target setting. Further, almost every country performs well in either renewable energy or energy efficiency, but rarely performs well in both. We find no support for the assertion that the policies are synergistic, but some evidence that they compete. However, multi-linear regression models for performance show that performance, especially in energy efficiency, is also strongly associated with general economic growth cycles, and not only efficiency policy as such. We conclude that renewable energy and energy efficiency are not synergistic policies, and that there is some competition between them.
