In the deep oceans the environment is perpetually dark ..then what is the source of energy their?

The deep ocean environment where sunlight cannot reach, energy sources are available from

  • The organic matters present in the upper photic zones sediments at the deep ocean beds providing source of energy for the organism present there.
  • After the death of fishes and other aquatic organisms the dead bodies sediment at the bottom to provide huge amount of organic matters to the deep sea levels.
  • There are several hydro thermal vents present at the bottom of the sea that emit chemicals. Some chemosynthetic bacteria are present that can use those chemicals as source of energy.

The movement of water in the world’s oceans creates a vast store of kinetic energy, or energy in motion. This energy can be harnessed to generate electricity to power homes, transport and industries.

The term marine energy encompasses both wave power — power from surface waves, and tidal power — obtained from the kinetic energy of large bodies of moving water. Offshore wind power is not a form of marine energy, as wind power is derived from the wind, even if the wind turbines are placed over water.

The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential of providing a substantial amount of new renewable energy around the world
