I hope to see electricity produced from hydrolysis then burning the hydrogen and cycling back like perpetual motion. There would be no carbon in the chain. This cannot be done now on an economic scale (prototype scale?).
Hydroelectric and Geothermal can be done but that it too localized.
Burning hydrocarbons to produce electricity to power personal transportation won't work in the long run. We are just trading one kind of pollution for another. Hydrogen fuel cell technology engines have always seemed to me to be a better solution but driving around the ''Hindenburg'' is a safety issue -- they have to work that one out
