"China vaulted past competitors in Denmark, Germany, Spain and the United States last year to become the world's largest maker of wind turbines, and is poised to expand even further this year." - The New York Times
This lead introduces the topic of the article fairly well. The story discusses how China is "vaulting past" other countries in green technology, but it also focuses on how the United States is falling behind.
However, the lead is a little misleading as it makes the reader believe Denmark, Germany and Spain would be discussed more in depth, but they aren't even mentioned.
Additionally, because China and the U.S. are the only ones mentioned, perhaps the lead is just aiming to be specific instead of just "China is vaulting past other countries..." It's good to be specific, but in this instance, I think it misleads the reader about the topic of the story.
When isolated, the lead works great. It flows well, entices the reader and gives good information according to the elements of news.
The words, "this year" give immediacy and "United States" proximity. Most importantly, it also gives impact. "World's largest maker of wind turbines" should bring about relevancy for Americans worried about the environmental issues and it also incites curiosity of how this title effects other countries.
