We use that for other things

Post #309,530 by drook 6/9/09 12:31:11 PM Reply	Pretend I don't know how to read that chart And add in the fact that it talks about supplies, but doesn't break down usage. What are you trying to show me? -- Drew
Post #309,533 by boxley 6/9/09 12:49:35 PM Reply	maybe this one http://www.eia.doe.g...ecss_diagram.html 27.8 of all energy sources is supplied to transportation via oil we would have to not quite double current gas extraction to replace gasoline completely provided the money is spent on delivery infrastructure. A tax structure for roads would need to be factored into the ng price to be collected at delivery points. Wouldnt be terribly cheaper than gas but would be incredibly cleaner on the atmosphere. that is a huge benefit thanx, bill
Post #309,536 by drook 6/9/09 1:10:14 PM Reply	How are you doing the math? The way I read it, petroleum makes up 96% of all transportation inputs, and natural gas 2%. To completely replace petroleum with ng, you'd have to increase by 48 times the amount of ng provided to transportation. And since 3% of current production is going there, you'd have to have 144% of current ng production just for transportation. Add back the 97% of current production going to industrial, residential/commercial and electric, and you need 241% of current ng production to replace petroleum. Even assuming you could produce that much, and distribute it, and cars could be modified to run on it ... what would that do to the depletion curve? -- Drew
Post #309,539 by boxley 6/9/09 1:39:46 PM Reply	Re: How are you doing the math? differently than yourself petroleum makes up 39.8% of all energy sources 70%of which goes to transportation 39.8*.7=27.86 of all energy sources are provided by petroleum to the transportaton sector now Natural gas supplies 23.6% of all energy extraction and delivery would need to be doubled+3% to replace oil in the transportation sector without affecting other usage. Now according to naturalgas.org there is a 75year domestic supply so slicing that in 1/2 because of increased usage is 35years plus Canada has huge supplies. Of course we could import from elsewhere or develop stuff locally that isnt in the current accessable reserves does that help? thanx, bill

Estimates of likely but as yet undiscovered gas resources extend that projection to about 200 years. But when the natural gas thought to lie buried deep under the ocean in methane hydrates is added in, the potential is mind-boggling. Hydrates, ice crystals that trap methane molecules, form below a depth of 300 meters as a result of methane-producing bacteria. Very little is known about how much gas is bottled up in these crystals or how to get it out, but best guesses are that the reserves could, even with natural-gas consumption rates doubling over the next several decades, last tens of thousands of years. Using natural gas for transportation will drive up the cost of the conventional stuff. As usual, there are issues with methane clathrate, too... http://en.wikipedia....Methane_clathrate Cheers, Scott.
