  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 ...

    Marine Energy Basics: Ocean Thermal Energy Conversion Basic information about ocean thermal energy conversion. Marine Energy Projects Database A database that provides up-to-date information on marine energy deployments in the U.S. and around the world.

  4. Marine current power - Wikipedia

    en.wikipedia.org/wiki/Marine_current_power

    Ocean thermal energy conversion – Extracting energy from the ocean; Tidal power – Technology to convert the energy from tides into useful forms of power; Tidal stream generator – Type of tidal power generation technology; Wave power – Transport of energy by wind waves, and the capture of that energy to do useful work

    An ocean current is a continuous, ... On their journey, the water masses transport both energy (in the form of heat) and matter (solids, dissolved substances and ...

  6. Thermohaline circulation - Wikipedia

    en.wikipedia.org/wiki/Thermohaline_circulation

    Computer models of ocean circulation increasingly place most of the deep upwelling in the Southern Ocean, associated with the strong winds in the open latitudes between South America and Antarctica. [28] Direct estimates of the strength of the thermohaline circulation have also been made at 26.5°N in the North Atlantic, by the UK-US RAPID ...

  7. Wave power - Wikipedia

    en.wikipedia.org/wiki/Wave_power

    Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations, and other factors.

  8. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.

  9. 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 ...
