  • Siemens has installed a “market-ready” version of its 6 MW gearless wind turbine at SSE’s test site in Hunterston, Scotland. They will carry out final testing of the turbine, which uses direct drive technology, before it goes into production. [reNews]
  • India’s Welspun Energy, which will commission the world’s second-largest solar power plant and two other projects by December, will invest an additional $1.6 billion in new solar and wind projects over three years. [Business Spectator]
  • Global investment in clean energy fell to roughly $46 billion to $47 billion in the third quarter of this year as project finance for renewables stalled owing to policy uncertainty, overcapacity and cheap natural gas. [South China Morning Post]
