Electricity supply emerges as prime cyber attack target – German security agency

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.

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…

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.

Birds vs. Wind Turbines: New Research Aims to Prevent Deaths
Window collisions and cats kill more birds than wind farms do, but ornithologists say turbine impacts must be taken seriously. Scientists are testing a range of technologies to reduce bird strikes — from painting stripes to using artificial intelligence — to keep birds safe.

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.
The halt has caused increasingly severe shortages that threaten to close many factories in the United States and Europe.

What to Know About China’s Halt of Rare Earth Exports
Since early April, China has stopped almost all shipments of critical minerals that are needed for cars, robots, wind turbines, jet fighters and other technologies.
