1. An energy storage system, comprising:
a first in-ground fluid storage tank defining a first chamber;
a second in-ground fluid storage tank defining a second chamber;
a first fluid disposed in the first chamber;
a second fluid disposed in the second chamber;
a heating unit operably connected to the first in-ground fluid storage tank and adapted to heat the first fluid;
a cooling unit operably connected to the second in-ground fluid storage tank and adapted to cool the second fluid; and
a thermoelectric generator exposed to the first fluid and the second fluid and adapted to convert a temperature difference between the first fluid and the second fluid directly to electrical energy.
