Hmmm... let’s think about this...
28 billion gallons - population 300 million - works out to 93-1/3 gallon per year for every man woman and child in the country.
For family of 4 - 373 gallons per year - more than 1 gallon per day... JUST in resturants.
That’s a lotta deep-fat-fryin goin on.
I doubt this is correct...
You are spoiling my fun ^^, but that's OK. What you pointed out is interesting because even if it was true (which it obviously isn't) it would only supply a fraction of our energy needs.
