The U.S. is making concerted effort to revive plans for a 3,300 km long natural gas pipeline that stretches from the Caspian sea through Turkey to Austria. This Nabucco pipeline is still very much in its infancy, lacking adequate supply of natural gas as well as lacking transit rites through intermediary countries in order to become viable enough to start building. This pipeline could potentially provide energy from Central Asia, and the Caucasus to Europe, diversifying Europe's supplies of natural gas.
