  2. Marine energy - Wikipedia

    en.wikipedia.org/wiki/Marine_energy

    Marine energy, also known as ocean energy, ocean power, or marine and hydrokinetic energy, refers to energy harnessed from waves, tides, salinity gradients, and temperature differences in the ocean. The movement of water in the world's oceans stores vast amounts of kinetic energy , which can be converted into electricity to power homes ...

  3. Ocean thermal energy conversion - Wikipedia

    en.wikipedia.org/wiki/Ocean_thermal_energy...

    An ocean thermal energy conversion power plant built by Makai Ocean Engineering went operational in Hawaii in August 2015. The governor of Hawaii, David Ige, "flipped the switch" to activate the plant. This is the first true closed-cycle ocean Thermal Energy Conversion (OTEC) plant to be connected to a U.S. electrical grid.

  5. Tidal power - Wikipedia

    en.wikipedia.org/wiki/Tidal_power

    Tidal energy has a high initial cost, which may be one of the reasons why it is not a popular source of renewable energy, although research has shown that the public is willing to pay for and support research and development of tidal energy devices. [63] [64] [65] The methods of generating electricity from tidal energy are relatively new ...

  6. Pelamis Wave Energy Converter - Wikipedia

    en.wikipedia.org/wiki/Pelamis_Wave_Energy_Converter

    The Pelamis Wave Energy Converter was a technology that used the motion of ocean surface waves to create electricity. The machine was made up of connected sections which flex and bend as waves pass; it is this motion which is used to generate electricity.

  7. Osmotic power - Wikipedia

    en.wikipedia.org/wiki/Osmotic_power

    Osmotic power, salinity gradient power or blue energy is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO). Both processes rely on osmosis with membranes. The key waste product is brackish water ...
