The story opens with an extended scene-setting lead. Notice the descriptive "telling details" in the first two paragraphs, and how the first four graphs use long, mostly complex sentences. Then comes a change of pace. The writer uses a transition word, "but," and a short sentence to get the reader's attention:
But LNG generates as much emotion as energy.
In this one short sentence, the reporter, Paul Rogers, not only gives readers a "heads up" that he's changing gears, he also introduces them to the conflict that drives this story: the state's need for more sources of energy vs. a local community's protests against these proposals.
Good technique, good story.
