Loser: U.S. factories
When Democrats in 2022 created and expanded a slew of federal tax breaks for electric vehicles, solar panels, wind turbines, batteries,
they designed them to encourage companies to use components made in the United States.
That spurred a manufacturing boom, including solar-panel glass recyclers in Georgia and electric-vehicle assembly lines in Kentucky.
The new law could derail many of those factories.

Climate change could make ‘droughts’ for wind power 15% longer, study says - Carbon Brief
Extreme “wind droughts” that reduce power output from turbines for extended periods could become 15% longer by the end of the century

Toward Sustainable Rare Earth Element Production: Key Challenges in Techno-Economic, Life Cycle, and Social Impact Assessment
Rare earth elements (REEs) are 17 critical minerals used in many clean energy technologies like wind turbines and electric vehicles. Conventionally, we produce REEs from mining in few, geopolitically restricted regions. Developing systems that utilize new technologies and unconventional feedstocks provides an opportunity to meet increasing demand while improving sustainability. Techno-economic analysis (TEA), life cycle assessment (LCA), and social LCA (sLCA) are commonly used tools to assess t…

How to craft a deep reinforcement learning policy for wind farm flow control
Within wind farms, wake effects between turbines can significantly reduce overall energy production. Wind farm flow control encompasses methods designed to mitigate these effects through coordinated turbine control. Wake steering, for example, consists in intentionally misaligning certain turbines with the wind to optimize airflow and increase power output. However, designing a robust wake steering controller remains challenging, and existing machine learning approaches are limited to quasi-sta…

Condition Monitoring with Machine Learning: A Data-Driven Framework for Quantifying Wind Turbine Energy Loss
Wind energy significantly contributes to the global shift towards renewable energy, yet operational challenges, such as Leading-Edge Erosion on wind turbine blades, notably reduce energy output. This study introduces an advanced, scalable machine learning framework for condition monitoring of wind turbines, specifically targeting improved detection of anomalies using Supervisory Control and Data Acquisition data. The framework effectively isolates normal turbine behavior through rigorous prepro…

Active flow control of vertical-axis wind turbines: Insights from large-eddy simulation and finite-time resolvent analysis
Active flow control is applied to improve the aerodynamic performance of a NACA0018 airfoil operating as a single-bladed vertical axis wind turbine (VAWT). Results computed by wall-resolved large-eddy simulations (LES) highlight the detrimental effects of the dynamic stall vortex (DSV) and trailing-edge vortex (TEV) on turbine efficiency, primarily through increased drag and energy loss. The proposed flow control strategy effectively delays flow separation and suppresses large-scale vortex form…

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 …

Decarbonizing Mongolia's Energy Sector: A Techno-Economic Analysis of Hybrid Energy Solutions
To achieve carbon neutrality and enhance energy security, Mongolia is exploring a transition toward hybrid energy solutions integrating small modular reactors (SMRs) and renewable energy sources. This study assesses the feasibility of a grid-connected hybrid energy system that combines coal, solar photovoltaic (PV), wind turbines, battery energy storage systems (BESS), and SMRs to reduce greenhouse gas emissions and improve energy reliability.

China has suspended almost all exports since April 4 of seven kinds of #rare #earth metals,
as well as very powerful magnets made from three of them.
