ReutersYou may have heard that SunEdison, the world's largest renewable energy firm, has filed for bankruptcy. There are a few fairly obvious ways it could have avoided this fate. It could have grown more slowly (but of course, then it wouldn't have attracted Wall Street's attention in the first place). It could have taken on less debt (but of course, without its $11 billion debt pile it wouldn't have grown as fast). It could have been more transparent with its shareholders and creditors as disaster unfolded (but then its demise would most likely have occurred even more rapidly). Could've, should've, would've — this is the hindsight story everyone has been writing. But in the jargon-filled world that is renewable energy, there are nuances in that narrative that investors — and anyone concerned with the health of this burgeoning industry and its impact on the environment — need to understand.
