The term was popularized through Sustainable Development Goal 14 which is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording of the goal is to " Conserve and sustainably use the oceans, seas and marine resources for sustainable development ".
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
Offshore energy is the generation of electricity using ocean-based resources. This includes using wind, thermal [clarification needed], wave, and tidal movement to convert to energy. [56] Understanding the seafloor and geological features can help develop the infrastructure to support these renewable energy sources. [57]
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 ...
The water current can be used to turn turbines for hydroelectric generation. The ocean is an example of a natural resource. Ocean waves can be used to generate wave power, a renewable energy source. Ocean water is important for salt production, desalination, and providing habitat for deep-water fishes. There is biodiversity of marine species in ...
This compound is a major energy source, forming the basis of the sulfur cycle in hydrothermal vent ecosystems. In the colder waters surrounding vents, sulfur-oxidation can occur using oxygen as an electron acceptor ; closer to the vents, organisms must use alternate metabolic pathways or utilize another electron acceptor, such as nitrate.
Ocean thermal energy conversion (OTEC) is a renewable energy technology that harnesses the temperature difference between the warm surface waters of the ocean and the cold depths to run a heat engine to produce electricity. It is a unique form of clean energy generation that has the potential to provide a consistent and sustainable source of power.
Water undergoes electrolysis at high temperatures to form hydrogen gas and oxygen gas. The energy to perform this is extracted from renewable sources such as wind power. Then, the hydrogen is reacted with compressed carbon dioxide captured by direct air capture. The reaction produces blue crude which consists of hydrocarbon.
