HVDC in the US

 "HVDC lines are cheaper to build and require less land area than equivalent AC lines.  About 500 miles of HVDC lines operate in the U.S. today and have proved efficient.  No major advance seems to be needed... TransCanada, Inc. is proposing 2,200 miles of HVDC lines to carry wind energy from Montana and Wyoming south to Las Vegas and beyond"  (Scientific American, Jan. 2008).
