Thought you all might be interested to see it.
Assuming an average of 294,000 gallons.
1 gallon = 131.76 MJ ofEnergy
294,000 * 131.76 = 38,737,440 MJ
Homes that could power a year = 29,480
Miles you could go in a 30 mpg car = 8,820,000 (18 round trips to the moon)
Actual trips to the moon = 1+ [Saturn V 36,880,00 MJ of energy used]
Explosive power = 9.28KT
So yeah, it may be small in percent, but still a shitton of lost energy.
