UrduThe cost effectiveness of wind farms could be significantly improved by reducing the speed of wind turbines that are clustered together, which could improve their longevity and also reduce noise pollution. A team of researchers from the University of Adelaide led by Dr Rey Chin looked at the operation conditions of wind turbines, investigated those conditions relative to power output and performance, and how turbines interact with each other.

The difference is even greater if copper and aluminium recovered during mechanical pre-treatment are included.
Smart Devices to Schedule Electricity Use May Prevent Blackouts
Power plants generate electricity and send it into power lines that distribute energy to nodes where it can be used. But if the electricity load is more than the system’s capacity, transmission can fail, leading to a cascade of failures throughout the electric grid. In the journal Chaos, researchers show demand side control may be an effective solution to stabilizing the reliability of power grids that use a mix of energy generation sources.

New Investments and Research Indicate Multi-Trillion Dollar Market for Climate Restoration Through Carbon-Capture
Climate restoration is the global movement to remove the trillion tons of excess CO2 from the atmosphere to restore our air to preindustrial levels of carbon dioxide and to preserve the Arctic ice. Given the climate emergency, climate restoration is a critical third pillar of climate action, complementing ongoing mitigation and adaptation efforts. New technologies and natural solutions for reducing CO2 levels in the next 30 years already exist and the costs for global-scale implementation are projected to be less than 1-3% of the global annual GDP.
