As a technological society we have become spoiled by the concentrated energy
layed down millions of years ago by plants and microscopic
photosynthesizers. Over the course of just a few centuries we are quickly
using energy that was collected over a period of millions of years. Sensible
replacements may not be forthcoming.
One thing that would help transportation would be to allocate all petroleum
and coal solely to the use of transportation. Don't use these two
nonrenewable resources to produce electricity, which can be better done
using nuclear, geothermal, and ect.
Second, more efficient internal combustion engines and vehicles.
Third, keep researching more technologies for when the stop gap measures are
