Wouldn't it be a lot easier to reduce our consumption of carbon-based fuels?

Do we really need to burn up 75 kilowatts of hydrocarbon fuel energy just to
visit a friend in the next city? Electricity or hydrogen fuel seem to make
more sense.


Electricity and hydrgogen fuel cells are not energy sources in the
macro context. they are energy transfer, just like springs.
They do not solve the problem you seem to think they solve.

(They do solve a DIFFERENT problem, which is why they're a good
idea, anyway.)
