I am not sure. I was hoping someone else would answer that question.
I don't think so.

NOTES

The following conversion rates were used:

Jet fuel = 135,000 Btu/gallon

Compressed natural gas = 138,700 Btu/gallon

Aviation gasoline = 120,200 Btu/gallon

Distillate fuel = 138,700 Btu/gallon

Automotive gasoline = 125,000 Btu/gallon

Residual fuel = 149,700 Btu/gallon

Diesel motor fuel = 138,700 Btu/gallon

Natural gas = 1,031 Btu/ft3

Electricity 1kWh = 3,412 Btu, negating electrical system losses. To include approximate electrical
system losses, multiply this conversion factor by 3.
