Alpha Natural Resources Inc., is one of the biggest coal companies in America, and recently the company has decided to file for bankruptcy. The company's filing comes just as the president of the United States is about to unveil new measures that are aimed at cutting greenhouse gas emissions that are produced from coal-fired power plants.

The company has blamed regulatory standards that favor renewable energy as the reason why it has decided to file. Not only that, but the price for its coal has been tumbling, and that too has contributed to the decision to file bankruptcy.

When it comes to metallurgical coal that is used to create steel, Alpha is the third largest supplier of it. However, a slowdown in China has also affected Alpha's business.
