Experts urge rethink on renewable energy and its environmental impact
Renewable energy has become a key part of the global energy transition, presenting itself as the clean alternative to fossil fuels. But green or renewable does not mean zero impact. Let's take a look at the fine print.

"Although the principles of international climate diplomacy suggest that poorer countries, being less responsible for climate change, have less duty to go green, many face strong economic incentives to do so anyway."

Interactions in Rare Earth Doped Nanoparticles: A Multi-Transition, Concentration, and Excitation Path Analysis
Understanding and modeling energy transfer mechanisms in rare-earth-doped nanomaterials is essential for advancing luminescent technologies used in bioimaging, optical thermometry, and solid-state lasers. In this work, we investigate the photoluminescence dynamics of Yb3+ and Er3+ ions in Y2O3 nanoparticles over a wide concentration range (0.5-17%), using both direct and upconversion excitation. Luminescence decays of green, red, and near-infrared transitions were measured and analyzed using a …

Green Transition with Dynamic Social Preferences
We examine a green transition policy involving a tax on brown goods in an economy where preferences for green consumption consist of a constant intrinsic individual component and an evolving social component. We analyse equilibrium dynamics when social preferences exert a positive externality in green consumption, creating complementarity between policy and preferences. The results show that accounting for this externality allows for a lower tax rate compared to policy ignoring the social norm …

- A statistical mechanical view of complex economies under the green transition
Filippo Marcuccini, Giacomo Livan

While the rare earth market is dominated by China, Canada also has some of the largest reserves in the world.
But new rare earth mining projects have to balance the need for these materials with the environmental impacts that mining has on the land. 
Instead of starting from scratch, the University of Alberta and Calgary-based CVW CleanTech are trying to mine these valuable substances from tailings, a waste product of open-pit oilsands mining.
Previously known as Titanium …

Rare earth elements are a key part of the transition to a green economy. From magnets in wind turbines to batteries in electric vehicles, they’re needed for technology that is increasingly in demand.

Copper Mining and Vehicle Electrification | IEF Report
Many studies have raised concerns that copper supply cannot meet the copper demands of both the green energy transition and equitable global development. This report addresses this issue by projecting copper supply and demand from 2018 to 2050 and placing both in the historical context of copper mine output.

Robin Green Function Estimates and a Model of Mammalian Lungs
The present paper establishes delicate properties of the Green function with Robin boundary conditions, in particular, elucidating the nature of the passage between the Dirichlet-like and Neumann-like behavior. This yields sharp quantifiable bounds on the corresponding harmonic measure and proves the phase transition in the behavior of the total flow earlier conjectured in physics literature in concert with the efficacy of mammalian lungs.

Twist-Tunable Spin-to-Charge Conversion and Valley-Contrasting Effects in Graphene/TMDC Heterostructures

Twist-Tunable Spin-to-Charge Conversion and Valley-Contrasting Effects in Graphene/TMDC Heterostructures
We consider graphene deposited on monolayers of such transition-metal dichalcogenides like MoSe$_2$, WSe$_2$, MoS$_2$, and WS$_2$. Our key objective is to study the impact of relative twist angle between the monolayers on the proximity-induced spin-orbital effects and orbital phenomena in graphene. To do this we used an effective model Hamiltonian for low-energy states, taken from available literature. The Green function formalism is used to calculate analytical formula for the spin Hall effect…

"the battery-electric vehicle market share is still far from where it needs to be—around 15% for cars"
A rounding off in favour of the EU automotive industry's whingeing plea – it's at 17% so far this year. If you round it up (to 20%), however, the targets have already been met.

Wind farms important to achieving net zero, says researcher
Few energy technologies divide public opinion quite like wind turbines. To some, they are elegant icons of the green transition, while others proclaim them to be monstrous eyesores that ruin the landscape. Whether you love them or hate them, one thing is clear: if the UK is to meet its net zero target by 2050, then wind power will have to play a dominant role in getting us there. Policy makers have signaled their commitment, having recently approved one of the largest wind farms in the world to…

A statistical mechanical view of complex economies under the green transition
We propose a stylized model of a complex economy to explore the economic tradeoffs imposed by the so called "green transition" -- the shift towards more sustainable production paradigms -- using tools from the Statistical Mechanics of disordered systems. Namely, we promote the parameters of a standard input-output economic model to random variables, in order to characterize the typical statistical properties of its equilibria. A central feature of our work is the explicit inclusion of a waste v…

Analytical solution of coupled self--consistency and linearised Usadel equations for the dirty finite--sized superconductor at critical temperature
In this manuscript we analytically investigate the linearised Usadel equation and the self--consistency equation, defining the critical temperature of the superconducting phase transition of a finite--sized superconductor in the dirty limit. This is a system of coupled differential and integral equations for the anomalous Green function and the order parameter of the superconductor. The formal solution of the system is found for the general case of the linearised boundary conditions, reducing t…

It is fascinating to see how Poland 🇵🇱, once an unlikely leader in the energy transition, is increasingly giving the green light to smart use of renewable energy.
Dynamic energy contracts make smart energy use attractive to consumers. Supportive optional network tariffs offer an additional boost.

What makes developments in Poland 🇵🇱 around dynamic tariffs interesting for other European countries to consider is the innovation that has also been set in motion in distribution network tariffs. Today marks exactly one year since dynamic energy tariffs became available from all major energy suppliers in Poland. This obligation stems from the EU Electricity Directive 2019, which gives consumers throughout the European Union the right to choose such a tariff (and also applies to other Eu…
