Wind energy: On the grid, off the checkerboard

Researchers have developed a new way to study wake effects that includes the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output.

Using mines as pumped storage power plants

Pumped storage power plants are firmly established in the German power grid: surplus electricity can be stored for a moment and then quickly supplied during a demand peak. The BINE Projektinfo brochure 'Storing wind energy underground' presents a concept of how to reuse abandoned ore mines as pumped storage power plants.
