Global warming: Does it take MORE energy to create hydrogen than PROVIDED in hydrogen fuel cell cars?

Jack Stone asked:
The round trip is a net loss isn’t it? We use electricity to convert H2O into H and O.
The round trip is a net loss isn’t it? We use electricity to convert H2O into H and O.
Then in a hydrogen fuel cell car, we RE-convert the H and O back into H2O again.
So it is a round trip.
But since every mechanical device LOSES energy through friction and heat and waste, the round trip from H2O to H & O and back to H2O LOSES energy.
Isn’t this right? So how will a hydrogen economy run the country or replace oil-burning cars?
