Year 2000

Over the last decades, the discussion on climate change, together with catastrophic events in the power sector, has raised global interest for radical policy changes. Since the year 2000, Germany´s Renewable Energy Sources Act (EEG) has been a forerunner in triggering large-scale decentralized deployment of renewable energy. Although built on a relatively large social consensus, the consequences of the German ‘Energiewende’ have also raised conflicts between communities and investor-oriented project developers. This chapter reviews the increasing role of energy co-operatives as means to involve civil society, mitigate conflicts in planning, and distribute subsidies more evenly among a variety of often rural stakeholders.

Abstract Background The study presented here systematically examines the potential involvement of dental, oral and maxillofacial centres (ZMK) in the management of pandemia or in large-scale emergencies. It looks at available material and infrastructural resources and how they can be brought to bear in such incidents or situations. The aim was to gain an initial scientific overview of how ZMK can potentially contribute to the handling of a pandemia or mass casualty (MASCAL) situation in terms of available resources as well as their location within the hospital as a whole and their integration into the existing infrastructure. The study was conducted on the basis of a questionnaire consisting of 70 individual questions, which was sent to all universities in Germany that offer a course of study in dental medicine. The responses were then statistically evaluated. Results The study outlines the current status of ZMK and discusses what could be an important component of emergency medical care in the overall hospital context. Conclusion The involvement of ZMK—with their own resources and existing infrastructural links to the hospital as a whole—could lead to faster and more effective patient treatment in the event of a pandemic or MASCAL situation.

The Given

This chapter starts with an introductory part, explaining the role of business models and analyzing the different financial models of ownership. It has been concluded that in renewable energy projects, ownership business models center in specialized complexity, economies of scale, capital costs, and financing perspectives based on its own characteristics. It has many favorable features including the ability to provide power to local communities and create jobs. However, business models include several decisive financing, service, and monitoring characteristics. Business models should be dynamic, while being adjusted to the special conditions, features, and risks of the given project. In renewable energy projects, ownership business models center on the specialized complexity, economies of scale, capital costs, and financing perspectives. The public-private partnership (PPP) is usually the optimum business model option for medium- to large-scale or grid-connected renewable energy projects, and is usually applied with a structure of a built-own-operate-transfer or multiparty ownership.

Air Capture

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.

Collective Navigation

The mass migration of animals is one of the great wonders of the natural world. Although there are multiple benefits for individuals migrating in groups, an increasingly recognized benefit is collective navigation, whereby social interactions improve animals’ ability to find their way. Despite substantial evidence from theory and laboratory-based experiments, empirical evidence of collective navigation in nature remains sparse. Here we used a unique large-scale radiotelemetry dataset to analyse the movements of adult Pacific salmon ( Oncorhynchus sp.) in the Columbia River Basin, USA. These salmon face substantial migratory challenges approaching, entering and transiting fishways at multiple large-scale hydroelectric mainstem dams. We assess the potential role of collective navigation in overcoming these challenges and show that Chinook salmon ( O. tshawytscha ), but not sockeye salmon ( O. nerka ) locate fishways faster and pass in fewer attempts at higher densities, consistent with collective navigation. The magnitude of the density effects were comparable to major established drivers such as water temperature, and model simulations predicted that major fluctuations in population density can have substantial impacts on key quantities including mean passage time and fraction of fish with very long passage times. The magnitude of these effects indicates the importance of incorporating conspecific density and social dynamics into models of the migration process. Density effects on both ability to locate fishways and number of passage attempts have the potential to enrich our understanding of migratory energetics and success of migrating anadromous salmonids. More broadly, our work reveals a potential role of collective navigation, in at least one species, to mitigate the effects of anthropogenic barriers to animals on the move.
