Ever heard of future alternative fuels such as hydrogen fuel cells?
How do you produce the compressed hydrogen required to run hydrogen fuel cells? "Currently, global hydrogen production is 48% from natural gas, 30% from oil, and 18% from coal; water electrolysis accounts for only 4%."-Wikipedia
That is, we produce hydrogen by extracting it from hydrocarbons AND we do it using energy we obtain from burning similar hydrocarbons.
Before we crack that particular solution as an 'alternative' to fossil fuels we would need to reliably produce cheap electricity from renewable sources.
Even then, do we really want to use water to fuel our cars? As harmless as it sounds we would essentially be sucking out oxygen from street-level in industrial amounts and converting it into water vapour (which would act as a greenhouse gas and produce large amounts of cloud cover). We would need to ideate a complex system to make this sustainable.
Further engaging in this discussion would be off-topic, but it's fair to say that unless we find or refine a source of cheap energy sometime soon, suburban living will continue to rise in price as a function of energy values.
