The transformation of energy systems is influencing economic policy agendas all over the world, particularly in industrialized countries. In this process, Germany has taken a pioneering role, and hence the technical innovations, legal frameworks, and business models established there are also of interest for other countries trying to achieve broader use of renewable energies. Energy cooperatives have been an important building block in the energy transition in Germany, although their practical importance is neither quantitatively nor qualitatively reflected in the academic literature. Drawing on recently collected data, this paper presents an overview of German energy cooperatives in terms of organization, financing, and membership. We then review literature from economics and the social sciences that has been used to analyze cooperatives on various levels in other fields. We discuss how these theories could be applied to create a better understanding of energy cooperatives, and we derive a preliminary research agenda for their analysis. We also assess the scope for interdisciplinary work among economists, sociologists, and other disciplines.
Consumption-based CO2 emissions, which are commonly calculated by means of environmentally extended input-output analysis, are gaining wider recognition as a way to complement territorial emission inventories. Although their use has increased significantly in the last years, insufficient attention has been paid to the methodological soundness of the underlying environmental extension. This should follow the internationally agreed accounting rules of the System of Environmental-Economic Accounting, which addresses the activities undertaken by the residents of a country, independent from where these take place. Nonetheless, some footprint calculations use extensions that account for all the activities within the territory, which leads to methodological inconsistencies. Thus, this article introduces the most relevant conceptual differences between these accounting frameworks and shows the magnitude of the gap between them building on the data generated for the EXIOBASE model. It concludes that the differences are high for many countries and their magnitude is increasing over time.
Achieving a truly sustainable energy transition requires progress across multiple dimensions beyond climate change mitigation goals. This article reviews and synthesizes results from disparate strands of literature on the coeffects of mitigation to inform climate policy choices at different governance levels. The literature documents many potential cobenefits of mitigation for nonclimate objectives, such as human health and energy security, but little is known about their overall welfare implications. Integrated model studies highlight that climate policies as part of well-designed policy packages reduce the overall cost of achieving multiple sustainability objectives. The incommensurability and uncertainties around the quantification of coeffects become, however, increasingly pervasive the more the perspective shifts from sectoral and local to economy wide and global, the more objectives are analyzed, and the more the results are expressed in economic rather than nonmonetary terms. Different strings of evidence highlight the role and importance of energy efficiency for realizing synergies across multiple sustainability objectives.
Although a substantial economic energy saving potential exists in the residential sector of the European Union, the energy efficiency service (EES) market is much less developed in this market segment than in other demand sectors (e.g. the industry or the public/service sector).
This paper presents an analysis of the current situation and existing potentials for future expansion. A specific analysis methodology has been developed and applied by a research consortium in 18 EU countries. This methodology has mostly built upon an extensive review of the existing literature and on interviews of a large number of acknowledged experts. Its application has allowed identifying encouraging development trends in specific market segments where the possibility of aggregating the EES demand or of exploiting good relationships with customers have created interesting investment opportunities. These trends have been observed in particular in Germany, Denmark, France, Flanders (BE), Hungary, Romania and UK. The assessment performed has also allowed discussing a series of strategies and policy measures that can be adopted to overcome existing barriers to market development. The general conclusion drawn in the paper is that energy efficiency policies supporting EES markets in the residential sector are highly needed. Although EU policies have typically a limited direct impact, they can increase trust into EESs and EES providers. At the national level, a stronger collaboration of governments or local administrations with banks to finance EESs is still very necessary in many EU countries.
