What would use more fuel, a full 747 flying from New Yoek to chicago, or each passenger driving an SUV instead
Answer:
A 747 gets about 100 miles per gallon per passenger. The SUVs would use about 10 times as much fuel, at 10 MPG. At 20 MPG it would only (!) be five time as as much. Details:

Each passenger driving a SUV! I got it. But it does seem like more pollution than a car when you see the steam coming out of those engines.
Individual drivers would consume far more fuel, even if they were all driving hybrids! Fully loaded 747 = 80 miles per passenger per gallon.
"While this difference seems very small, remember that the Concorde can only carry a maximum of 100 passengers, whereas the 747 is typically configured to carry about 400 passengers. In terms of fuel use per passenger carried, one gallon of fuel on Concorde will take one passenger 16.7 miles, but on a 747 one passenger can travel 80 miles. The 747 is 4.8 times more fuel efficient than a Concorde (and more fuel efficient than two people sharing a private car, too!)."
A 747 gets about .20 miles to the gallon.
A SUV gets about 20 miles to the gallon.
Therefore 100 SUVs would get the same mileage. So if each SUV was full it would be about equal. If there were only 1 or 2 passengers then the 747 would be cheaper.
SUV, but a train uses much less than the 747 .
As Bob showed, the SUVs would use far more fuel.
The reason airplanes are an environmental problem is because they make travelling long distances relatively easy. You're probably not going to drive across the country, but if you can fly across in a few hours, that might be acceptable. Thus even though flights are relatively fuel efficient, they go such long distances that they create a lot of emissions.
