Record Decline in Driving, Record Level of Conservation

carlosz,

10 mile per gallon seems low, i'd like to check the math; where did you get the 20 mil. barrels/day on the EIA site? Is that only for transportation use, or does it include all uses? I found on the EIA site motor gasoline sales to be about 180 x 10^6 gallons per month, for all grades of gasoline sold in the US. Dividing that into 245 x 10^9 miles/month gives about 175 miles/gallon! so something is off in my calculations. One thing you didn't address; is the 245 billion miles traveled per month for passenger traffic, or does it include over the road truck traffic. ORT average mileage is about miles per gallon of diesel. What is the calculation if you divide passenger traveled miles by gasoline useage? Then i'd be interested to see what a 5 mpg improvement would do to our useage.

let me know if this makes sense.
