" The energy required to dissociate the atoms of a water molecule in this way is still more than the energy recovered by recombining them back into water"

The energy required to drill for oil and transport oil and refine oil is still more than the energy recovered
by burning it in your automobile.

That is generally incorrect (barring occasional miscalculation) with relation to the oil that is currently being extracted.  It is correct with respect to some very expensive-to-drill locations that are not yet being tapped, hence why they are not being tapped yet.  Oil companies are in it to make money.  It if costs more money in terms of energy (oil companies do not get free energy) than they can sell the oil for, they would be losing money.  Yet they are not losing money.  Draw your conclusions.
