  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. Environmental impact of electricity generation - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Hydropower, biomass, geothermal and ocean power may generally be low-carbon, but poor design or other factors could result in higher emissions from individual power stations. For all technologies, advances in efficiency, and therefore reductions in CO 2 e since the time of publication, have not been included.

  4. North American power transmission grid - Wikipedia

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

    There are three minor power grids in North America: the Alaska Interconnection, the Texas Interconnection, and the Quebec Interconnection. The Eastern, Western and Texas Interconnections are tied together at various points with DC interconnects allowing electrical power to be transmitted throughout the contiguous U.S., Canada and parts of Mexico.

  5. PJM Interconnection - Wikipedia

    en.wikipedia.org/wiki/PJM_Interconnection

    From 1996 to 1999, the FERC made a series of decisions which resulted in the restructuring of the U.S. electric utility industry. The FERC's intention in doing so was to open the wholesale power market to new players, with the hope that spurring competition would save consumers $4 to $5 billion per year and encourage technical innovation in the industry.

  6. 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 ...

  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. Geomagnetically induced current - Wikipedia

    en.wikipedia.org/wiki/Geomagnetically_induced...

    The complexity of power grids, the source ionospheric current systems and the 3D ground conductivity make an accurate analysis difficult. [7] By being able to analyze major storms and their consequences we can build a picture of the weak spots in a transmission system and run hypothetical event scenarios.

  9. 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.
