Energy companies here in the states are already putting R&D into alternative fuels. The hope is they aren’t too late.

Fuels are only one aspect. As has been mentioned, Nuclear Power, Solar Power, (all those renewables)… increasing their efficiencies.

Also finding effective alternatives to common industrial materials/synthesizing new materials… etc etc.

(From this point the rest is just speculation… but) Changing the type of fuel that powers our Cars seems a little half-assed.
