Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

open access: yesSustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

Regulation, Taxation, and Resources: Unpacking Greenhouse Gas Emission Drivers Across G7 Economies

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT Advanced economies are under growing pressure to downscale greenhouse gas (GHG) emissions without undermining growth, yet G7 (Group of Seven) nations, representing almost 10% of the world's population, still generate one quarter of global GHGs.

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

open access: yesWildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Evaporitic Chert Provenance: Evaluating Petrographic and Geochemical Workflows for Source Discrimination

open access: yesArchaeometry, EarlyView.
ABSTRACT Chert tools were widely used in prehistory by human societies due to their knapping suitability and availability, but their relatively uniform composition, especially in evaporitic cherts, complicates sourcing, requiring specialised analytical methods.
