II. Extended information - new energy:

(1) New energy:

1. New energy generally refers to renewable energy developed and utilized on the basis of new technologies, including solar energy, biomass energy, water energy, wind energy, geothermal energy, and wave energy. , ocean current energy and tidal energy, as well as the thermal cycle between the ocean surface and the deep layer, etc.; in addition, there are hydrogen energy, biogas, alcohol, methanol, etc., and the energy sources such as coal, oil, natural gas, and water energy that have been widely used are called for conventional energy. As conventional energy sources become limited and environmental problems become increasingly prominent, new energy sources that are environmentally friendly and renewable have attracted more and more attention from various countries.

2. Currently, new energy sources that can form industries in China mainly include hydro energy (mainly small hydropower stations), wind energy, biomass energy, solar energy, geothermal energy, etc., which are recyclable clean energy sources. The development of the new energy industry is not only an effective supplement to the entire energy supply system, but also an important measure for environmental governance and ecological protection. It is the ultimate energy choice to meet the needs of sustainable development of human society.

3. It includes the following characteristics:

1) It is rich in resources and generally has renewable characteristics and can be used sustainably by humans.

2) The energy density is low and requires a large space for development and utilization;

3) It contains no carbon or very little carbon and has little impact on the environment;

4) Wide distribution, conducive to small-scale decentralized utilization;

5) Intermittent supply, high volatility, which is detrimental to continued energy supply;

6) At present, in addition to hydropower, The development and utilization cost of renewable energy is higher than that of fossil energy.

(2) New energy industry:

The new energy industry mainly stems from the discovery and application of new energy. New energy refers to energy that has just begun to be developed and utilized or is being actively researched and needs to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. Therefore, the series of processes that units and enterprises engaged in developing new energy here are called the new energy industry.
