Second, expand 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, wave energy, ocean current energy, tidal energy, and thermal cycle between the surface and the deep ocean. In addition, there are hydrogen energy, biogas, alcohol, methanol and so on. The widely used energy sources such as coal, oil, natural gas and water are called conventional energy sources. With the limitation of conventional energy and the increasingly prominent environmental problems, more and more countries pay attention to new energy sources with environmental protection and renewable characteristics.
2. Recently, in China, the new energy sources that can form industries mainly include hydropower (mainly small hydropower stations), wind energy, biomass energy, solar energy and geothermal energy. , is a clean energy that can be recycled. Developing new energy industry is not only an effective supplementary means to the whole energy supply system, but also an important measure for environmental governance and ecological protection, and the ultimate energy choice to meet the sustainable development needs of human society.
3, including the following functions:
1) is rich in resources, which are generally renewable and can be used permanently by human beings.
2) The energy density is low, and more space is needed for development and utilization;
3) no carbon or low carbon content, which has little impact on the environment;
4) wide distribution, which is beneficial to small-scale decentralized utilization;
5) intermittent supply, which fluctuates greatly, is not conducive to continuous energy supply;
6) At present, except 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 comes from the discovery and application of new energy. New energy refers to the energy that has just been developed or actively studied and needs to be popularized, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, nuclear fusion energy and so on. Therefore, the new energy industry is a series of processes that units and enterprises engaged in developing new energy here.
