What are the new energy enterprises in China?
All forms of new energy come directly or indirectly from the heat generated by the sun or the earth. Including solar energy, wind energy, biomass energy, geothermal energy, nuclear fusion energy, water energy and ocean energy, as well as energy generated by biofuels and hydrogen from renewable energy. It can also be said that new energy includes all kinds of renewable energy and nuclear energy. Compared with traditional energy sources, new energy sources generally have the characteristics of less pollution and large reserves, which is of great significance to solve the serious environmental pollution problem and the depletion of resources (especially fossil energy) in the world today. At the same time, because many new energy sources are evenly distributed, it is also of great significance to solve the war caused by energy.
According to the world's assertion, resources such as oil and coal mines will be reduced at an accelerated rate. Nuclear energy and solar energy will soon become the main energy sources. The United Nations Development Programme (UNDP) classifies new energy sources into the following three categories: large and medium-sized hydropower; New renewable energy sources, including small hydropower, solar energy, wind energy, modern biomass, geothermal energy and ocean energy (tidal energy); Traditional biomass.
Generally speaking, conventional energy refers to energy that is technically mature and has been used on a large scale, while new energy usually refers to energy that has not been used on a large scale and is being actively developed. Therefore, coal, oil, natural gas and large and medium-sized hydropower are regarded as conventional energy sources, while solar energy, wind energy, modern biomass energy, geothermal energy, ocean energy, nuclear energy and hydrogen energy are regarded as new energy sources. With the progress of technology and the establishment of the concept of sustainable development, the industrial and domestic organic wastes that used to be regarded as garbage have been re-recognized, and have been deeply studied, developed and utilized as a material for the utilization of energy resources. Therefore, the resource utilization of waste can also be regarded as a form of new energy technology.
The energy resources that mankind has just developed and utilized and need further research and development are called new energy sources. Compared with conventional energy, new energy has different contents in different historical periods and scientific and technological levels. In today's society, new energy usually refers to nuclear energy, solar energy, wind energy, geothermal energy, hydrogen energy and so on.
According to the category, it can be divided into: solar wind power generation, biomass energy, biodiesel, ethanol, new energy, automobile fuel cell, hydrogen energy, garbage power generation, building energy conservation, geothermal energy, tidal energy, dimethyl ether, combustible ice and so on.
