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,
