Ocean energy is not biomass energy.
Energy is classified by source. The first category is solar energy from outside the earth, including fossil resources (coal, oil, natural gas, etc.), biomass energy, hydropower, wind energy . energy, ocean energy, etc.
The second category concerns the energy resources contained in the earth itself, mainly nuclear fission energy, nuclear fusion energy and geothermal energy resources. The third category is energy formed by the regular movement between the earth, moon, sun and other celestial bodies, such as tidal energy.
Depending on whether it can be regenerated, it is divided into renewable energy and non-renewable energy. Ocean energy refers to renewable energy linked to seawater. The ocean receives, stores and emits energy through thee through various physical processes. This energy exists in the ocean in the form of tidal energy, wave energy, temperature difference energy, salinity difference energy, and ocean current energy. , etc. .
Ocean energy utilization refers to the use of certain methods and equipment to convert various ocean energies into electrical energy or other usable forms of energy. Since ocean energy has the advantage of being renewable and not polluting the environment, it constitutes a new source of energy of strategic importance that urgently needs to be developed.
Energy characteristics
1. The amount of ocean energy contained in total ocean water is enormous, and the energy per unit volume, unit area and unit length smaller. This means that if you want to get large amounts of energy, you need to get it.hold from a large amount of sea water.
2. Ocean energy is renewable. Ocean energy comes from solar radiation and gravitation between celestial bodies. As long as the sun, moon and other celestial bodies coexist with the earth, this energy will be regenerated and will be inexhaustible.
3. Ocean energy can be divided into more stable and unstable energy sources. The most stable are the energy of temperature difference, the energy of salinity difference and the energy of ocean currents. Unstable energy is divided into two types: regular changes and irregular changes. Tidal energy and tidal current energy are unstable but change regularly.
4. Ocean energy is clean energy, which means that once developed it will have little impact on environmental pollution.
