New energy (NE): also known as unconventional energy. Refers to various forms of energy other than traditional 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.
New energy generally refers to renewable energy developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy and tidal energy, as well as the thermal cycle between the ocean surface and the deep layer.
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.
The new energy sources that can form industries in China 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.
The significance of new energy:
The rapid growth of energy demand in China has broken the long-term self-sufficient energy supply pattern in China. Since 1993, China has become a net oil importer, and its oil imports have increased year by year, enabling China to compete in the world energy market. As China's fossil energy, especially oil and natural gas, is relatively insufficient, China's energy supply will depend more and more on the international market in the future.
There are many uncertainties in international trade. The international energy price may tend to be stable with the improvement of the international peaceful environment, but it may also fluctuate with the turmoil of the international situation.
In the future, the instability of the international oil market and the fluctuation of oil prices will seriously affect China's oil supply and have a great impact on the economy and society. Vigorously developing renewable energy can relatively reduce the proportion of fossil energy in China's energy demand and its dependence on imported energy, and improve China's energy and economic security.
