There's a clear consensus that it's time for a greater push toward renewable energy. But some nations have been much faster out of the gate than others. What models are evolving in different parts of the world? Here in the U.S., shale gas has emerged as a cheap and relatively clean resource, but environmental concerns are mounting; meantime, renewables remain dependent on government subsidies. China has focused on building large, competitive producers, while the U.S. has concentrated more on making deployment more cost effective for end users. Europeans, suffering through fiscal challenges, are increasingly resentful of high prices. Who will solidify leadership in this sector? Which regions and technologies look most promising to investors? Which are closest to achieving maturity and critical mass?
