  2. Marine current power - Wikipedia

    en.wikipedia.org/wiki/Marine_current_power

    Marine currents can carry large amounts of water, largely driven by the tides, which are a consequence of the gravitational effects of the planetary motion of the Earth, the Moon and the Sun. Augmented flow velocities can be found where the underwater topography in straits between islands and the mainland or in shallows around headlands plays a major role in enhancing the flow velocities ...

  3. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    Energy from fossil or nuclear power plants and renewable sources is stored for use by customers. Simplified grid energy flow over the course of a day. Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid.

  4. 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 ...

  5. North American power transmission grid - Wikipedia

    en.wikipedia.org/wiki/North_American_power...

    In 1975 the AC ties were disconnected, because DC ties were found to work more reliably. [1] The Energy Policy Act of 1992 required transmission line owners to allow electric generation companies open access to their network [3] [4] and led to a restructuring of how the electric industry operated in an effort to create competition in power ...

    en.wikipedia.org/wiki/Okinawa_Yanbaru_Seawater...

    The Japan Society of Civil Engineers presented the company an Outstanding Civil Engineering Achievement Award on May 26, 2000 for its construction of the plant. [7] The operator could not put the power station into practical use because the demand for electric power in Okinawa had not grown as predicted, and the plant was not profitable as a ...

  7. Submarine power cable - Wikipedia

    en.wikipedia.org/wiki/Submarine_power_cable

    A submarine power cable is a transmission cable for carrying electric power below the surface of the water. [1] These are called "submarine" because they usually carry electric power beneath salt water (arms of the ocean, seas, straits, etc.) but it is also possible to use submarine power cables beneath fresh water (large lakes and rivers).

  8. Hydro-Québec's electricity transmission system - Wikipedia

    en.wikipedia.org/wiki/Hydro-Québec's_electricity...

    After the power outage was over, Hydro-Québec made numerous upgrades to its system in order to improve the power grid. Examples include the strengthening of electrical towers and power poles, and increasing the power supply. This was done to enable the utility to restore power more rapidly in the case of a massive ice striking Quebec again.

  9. Ocean general circulation model - Wikipedia

    en.wikipedia.org/wiki/Ocean_general_circulation...

    Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans. The oceanic general circulation is defined as the horizontal space scale and time scale larger than mesoscale (of order 100 km and 6 months).
