New energy classification
1. New energy sources are classified according to their formation and source:
(1) Energy from solar radiation, such as solar energy, water energy, wind energy, and bioenergy.
(2) Energy from the interior of the Earth, such as nuclear energy and geothermal energy.
(3), celestial gravitational energy, such as: tidal energy.
2. New energy is classified according to development and utilization status:
(1) Conventional energy sources such as water energy and nuclear energy.
(2) New energy sources such as bioenergy, geothermal energy, ocean energy, solar energy, and wind energy.
3. New energy is classified by attribute:
(1) Renewable energy sources such as solar energy, geothermal energy, hydro energy, wind energy, bioenergy, and ocean energy.
(2) Non-renewable energy sources such as nuclear energy.
4. New energy is classified according to the conversion process:
(1) Primary energy, directly from the energy of nature. Such as: water energy, wind energy, nuclear energy, ocean energy, bioenergy.
(2) Secondary energy sources such as biogas, steam, thermal power, hydropower, nuclear power, solar power, tidal power, wave power generation, etc.
