“12,000 watts per gallon.”

We know that the author of the above failed 9th grade science!

This is the chart I used to make my comparison.
Gasoline has about 13,000 MJ/kg in energy and lithium ion batteries about 0.46-0.72 MJ/kg.

The figure I used was just the top of my head

I thought E=MC(sq) means energy and mass are the same thing?

Any mass can also be expressed in terms of electrical energy or heat.

Is that not correct?

The refining of gas uses a lot of energy and must be considered when gauging the energy one gets from burning it. This article is from a lefty source, but it is interesting.
