1. There are broad and narrow definitions of new energy industry. New energy in a broad sense mainly realizes the effect of greenhouse gas emission reduction, including the efficient and comprehensive utilization of energy and resources, as well as renewable energy, alternative energy, nuclear energy, energy conservation, etc.
2. In a narrow sense, new energy refers to the common conventional energy excluded, which mainly refers to the assembly of wind energy, solar energy, biological energy, geothermal energy, marine energy, small hydropower and nuclear energy other than large-scale hydropower. At present, China's use of wind energy, marine energy, small hydropower and nuclear energy is mainly in the conversion of electric energy, while the use of solar energy, biological energy and geothermal energy should not only be converted into electric energy, but also be developed into the conversion of heat and gas. In general, the utilization of new energy mainly converts various energies into electric energy.
The new energy industry is a series of processes engaged by the units and enterprises that develop new energy. The new energy industry mainly stems from the discovery and application of new energy.
(1) Energy from solar radiation, such as solar energy, water energy, wind energy, biological energy, etc.
(2) Energy from the earth's interior, such as nuclear energy and geothermal energy.
(3) Celestial gravitational energy, such as tidal energy.
(1) Conventional energy, such as hydropower and nuclear energy.
(2) New energy, such as bioenergy, geothermal energy, marine energy, solar energy and wind energy.
3. New energy is classified by attributes:
(1) Renewable energy, such as solar energy, geothermal energy, water energy, wind energy, biological energy and marine energy.
(2) Non-renewable energy, such as nuclear energy.
4. New energy is classified according to conversion and transmission process:
(1) Primary energy, directly from natural energy. Such as: hydropower, wind energy, nuclear energy, marine energy, biological energy.
(2) Secondary energy, such as biogas, steam, thermal power, hydropower, nuclear power, solar power generation, tidal power generation, wave power generation, etc.
At present, under the dual-carbon goal, energy cooperation has become the main direction of cooperation among countries. China proposes to strive to reach the peak of carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. To achieve this goal, China will strengthen the construction of ecological civilization and accelerate the adjustment and optimization of industrial structure and energy structure.
