You are here. Geothermal energy is heat derived below the earthâs surface which can be harnessed to generate clean, renewable energy. This vital, clean energy resource supplies renewable power around the clock and emits little or no greenhouse gases -- all while requiring a small environmental footprint to develop.
  Geothermal energy is energy produced using the heat from under the earth.     Hydrothermal is energy produced by using the different temperatures of water. Pl â¦ aces in the Tropics with warm surface water but also deep cold water are most suitable.  Both geothermal and hydrothermal are renewable and clean.  Geothermal sources of hot water can be used to heat buildings.  Hot water is pumped through pipes located in the building walls to  heat the building.  Geothermal hot water can also be used as a household hot water  source.
