That's what makes a great mobile source of energy, lots of energy in a light weight.
It seems that Tesla has new, much more powerful batteries; both from the Roadster 2 (with 2X the battery capacity of their current batteries) and the Semi, with its reported 1MwH battery in a $180,000 vehicle.

Electricity is about 90% efficient, and it doesn't need to be transformed from liquid to heat to mechanical. And mechanically, an electric motor is nearly perfect, while a reciprocating piston engine is poor. Imagine driving a semi - with no shifting!
