Either no one noticed or they thought it wasn't very important.
There are several gas pipelines in the planning stages and there are several major gas fields that could be so huge as to be a game changer in world energy consumption. One newly discovered field is the Leviathan off shore field Israel has. Enter the new technology of fracking and the potential natural gas production (6,000 trillions of cubic feet)could far out strip oil as the preferred energy source.
How could cheap clean abundant natural gas effect oil prices and the petrodollar?
