The IC engine is only about 25% to 30% efficient so even generating
with say, 85% efficient fuel use may help overall.

Apart from fuel cells which can be higher than ICEs, what fuel did
you have in mind to have 85% efficiency?

Not so much the fuel but what burns it to power the generator.* Some
boilers can be that efficient.

Lets stop there. Are we talking of boilers or fuel used in association
with prime movers? They are world apart.

I can also assure you some boilers are far higher than that.

No ****, this is just a crude comparison for conversation, not a
comparison of boiler types.


What has a boiler got to do with this?

Boilers make steam that turns generators to make electricity.


the car may be operating at 80% of the energy instead of 25%.

I really suggest you lookup Carnot and the Second Law of Thermodynamics
before mentioning boiler and transmission in the same sentence. This
might assist in a more complete understanding of thermal engines:

Not interested in the fine details. The numbers are just to show that
electricity has the potential to be more efficient. If you want to do a
full analysis, be my guest, I'll at least look at it.

Since we are looking at transmission efficiency be sure to look at the
losses in gasoline too. It may be roughly 25% in an ICE but still has
to be transported using fossil fuel in ships, tankers, and pumping so
for every BTU of energy extracted from the earth there are losses along
the way to refine and move it to the point of use.
