About conserving fuel

Heard some say that navigating surfaced and submerged in turn can conserve fuel, but I wonder why. Of course it doesn't consume diesel when below water, but the battery still must be recharged by burning it, based on conservation law of energy, how come this way be more cost-effective? And I still haven't taken into account the energy loss due to the energy conversion efficiency of the generators.
