Physical science, energy research question

I found this article in the magazine, Science World. It was published in the December 10th issue 2012. What inferences can you make about how natural gas is used to generate electricity? What inferences can you make about the environmental impact of using natural gas to generate electricity? Why do you think this crater is still on fire? What does this say about the availability of natural gas in this part of the world?

Respond to these questions and share any information you think is helpful from your research.
