The story swirling around our media is that the discovery of gas under the sea across from Haifa last year (at the Tamar field) is about to be dwarfed by the next findings, at the Leviathan field. The numbers in this item are a bit opaque, at least to me, so we'll need to wait and see, I suppose.
The Tamar finds are apparently large enough to supply all our needs for 15 years. The Leviathan, if you believe the hype, are a game-changer. More ruminations on that when the picture clears.
