2015 was a record year for global investment in clean energy, with $ 329 billion invested in wind, solar panels, biomass plants and more around the world. Fully one-third of the 2015 clean energy investment occurred in China. That country saw investments of $ 110.5 billion last year. The United States was second with $ 56 billion.
But in spite of these investments some RE companies are struggling.  SunEdison, one of the big players, filed for bankruptcy in late April. The Spanish multinational solar & biofuel giant, Abengoa, is in “restructuring” proceedings.
