Rajendra Pachauri was ousted as chief of The Energy and Resources Institute (TERI) on Thursday amid an investigation into a sexual harassment case. Pachauri will be replaced by Ajay Mathur, who heads the government's Bureau of Energy Efficiency. Pachauri had headed TERI for over 30 years, and headed the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change for 13 years.
