Solar energy, land energy, thermal wind energy, tidal energy, ocean energy, bioenergy, hydrogen energy, etc. Tidal energy: refers to the energy contained in the periodic rise and fall of sea water. Solar energy: refers to the energy of thermal radiation from the sun. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Wind energy: kinetic energy generated by air flow. Wind energy is a renewable and clean energy with large reserves and wide distribution.
1. Tidal energy
Tidal energy refers to the energy contained in the periodic rise and fall of sea water. The level difference of water is expressed in potential energy and the speed of the current is expressed in kinetic energy. Both types of energy can be used and are a form of renewable energy.wheat. Because tides are the most reliable and regular among the various movements of seawater, and because they move up and down the shore, they are also the first to be recognized and used by humans. Among the various uses of ocean energy is the use of tides. the energy is the most mature.
2. Solar energy
Solar energy refers to the thermal radiation energy of the sun, which is mainly expressed in what is often called solar rays. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
3. Wind energy
Wind energy is the kinetic energy generated by air flow. Ae converted form of solar energy. Wind energy is a renewable and clean energy source with large reserves and wide distribution. Under certain technical conditions, wind energy can be developed and used as an important energy source. Wind energy utilization is a comprehensive engineering technology that converts the kinetic energy of wind into mechanical, electrical and thermal energy through wind turbines.
4. Ocean Energy
Ocean energy refers to the renewable energy attached to seawater. The ocean receives, stores and dissipates energy to through various physical processes. This energy comes in the form of tides. , waves, temperature differences, salinity gradients, currents, etc. exist in the ocean. Use technologies: tidal power generation, wave power generation, seawater temperature difference power generation, production of energy by difference in salinity, production of energy by ocean current.
5. Bioenergy
Bioenergy refers to various organisms produced by photosynthesis. Bioenergy is a form of energy stored in organisms as chemical energy from solar energy. as a support, biomass, which comes directly or indirectly from plant photosynthesis. Among various renewable energy sources, biomass is unique in that it constitutes stored solar energy and is the only renewable source of carbon that can be converted into conventional solid, liquid and gaseous fuels. Forms of use: direct combustion, thermochemical conversion, biochemical conversion of hydrogen energy.
6. Hydrogen energy
Hydrogen energy is a secondary energy because it is produced using other energy sources in a certain method, unlike coal, oil and natural gas. It can be extracted. directly from the ground. This type of energy will eventually be exhausted. If hydrogen energy can be produced from it,
this should ease the warning of the energy crisis. Form of use: direct combustion, by fuelBatteries are transformed into electricity, nuclear fusion.
