What are the classifications of new energy?

The various forms of new energy are directly or indirectly derived from the heat generated by the sun or deep inside the earth. These include solar, wind, biomass, geothermal, nuclear fusion, hydro and ocean energy, and the energy produced by biofuels and hydrogen derived from renewable sources. It can also be said that new energy sources include various renewable energy sources and nuclear energy. Compared with traditional energy sources, new energy sources are generally characterized by less pollution and large reserves, which are of great significance for solving the serious environmental pollution problems and the depletion of resources (especially fossil energy) in today's world. At the same time, due to the uniform distribution of many new energy sources, it is also important to solve the war caused by energy.

According to the world's assertion, resources such as oil and coal mines will accelerate. Nuclear energy and solar energy are about to become the main energy sources.

New Energy The United Nations Development Programme (UNDP) divides new energy into three broad categories: large and medium-sized hydropower; new renewable energy, including small-hydro, solar, wind, and modern biomass. Modern biomass, geothermal, ocean (tidal energy); traditional biomass (Traditional biomass).

Generally speaking, conventional energy refers to energy that is relatively mature in technology and has been used on a large scale. New energy usually refers to energy that has not been widely used and is being actively researched and developed. Therefore, coal, oil, natural gas, and large and medium-sized hydropower are regarded as conventional energy sources, and solar energy, wind energy, modern biomass energy, geothermal energy, ocean energy, nuclear energy, and hydrogen energy are used as new energy sources. With the advancement of technology and the establishment of the concept of sustainable development, industrial and domestic organic waste, which has been regarded as garbage in the past, has been re-recognized and intensively researched and exploited as a material for energy resource utilization. The resource utilization of waste can also be seen as a form of new energy technology.

The energy resources that are newly developed and utilized by human beings and need further research and development are called new energy sources. Compared with conventional energy sources, new energy sources have different contents in different historical periods and technological levels. In today's society, new energy usually refers to nuclear energy, solar energy, wind energy, geothermal energy, and hydrogen.

Classified by category: solar energy, wind power, biomass, biodiesel, fuel ethanol, new energy vehicles, fuel cells, hydrogen, waste-to-energy, building energy, geothermal energy, tidal energy, dimethyl ether, combustible ice, etc. .
