It's been a tough summer and fall for the world's biggest renewable energy developer. 

Since SunEdison announced its acquisition of Vivint Solar in July, the company's stock price has fallen by 70 percent. Just this week, executives announced they are laying off 15 percent of the company's workforce -- amounting to a cut of around 1,000 people.

How did a leading renewable energy company riding so high earlier in the year reverse course so quickly?

In this week's podcast, we'll discuss the factors behind SunEdison's recent woes and look at its new plan to get back on track.

Later in the show, we'll provide updates on Exelon's bid to buy up Pepco, Shell's decision to abandon Arctic drilling, and some energy bills making their way through Congress.

The Energy Gang is produced by The show features weekly discussions between energy futurist Jigar Shah, energy policy expert Katherine Hamilton and Greentech Media Editor Stephen Lacey.
