Thanks for the note, and for the quick fact the check. I've corrected that line to read "Part of the challenge is that global electricity demand is rising faster than renewable electricity output..."
RE Coal and China: Yergin did spend time talking about the rise of China and the importance of global shifts in energy demand to the emerging economies, as I noted in the post. He was less clear about the recent continued global growth of coal, likely reflecting the US-centric bias of his remarks. While touching on global trends, he really was talking about the major energy trends in the US from 2005-2014, and here, coal has been on the decline, even as it continues to grow rapidly abroad. Thanks for adding in that critical global perspective. Cheers,
