5 thoughts on “What new energy includes?”

  1. Solar energy, wind energy, geothermal energy, ocean energy, etc.
    The new energy is obtained from the use of new technologies and new materials compared to conventional energy sources. Such as solar energy, wind energy, ocean energy, geothermal energy, etc. Compared with conventional energy, new energy production scale is small and the range of use is narrow. The division of conventional energy and new energy is relative.

  2. 1. Nuclear energy is divided into nuclear cracks and composite energy. The former has been used by humans to generate electricity, and the nuclear fuel containing the fissure -changing pile is extremely limited. The problem of headache. In contrast, nuclear aggregation has very little radiation, and the fuel of nuclear aggregation can be said to be inexhaustible and inexhaustible.
    nuclear fusion is new energy, but nuclear cracks are not new energy.
    2. Biomass can be the energy provided by plants with life in nature. These plants use biomass as the medium to store solar energy. It is renewable energy. According to calculations, the energy stored in biomass is 27 billion kilowatts, which is two times larger than the current total energy consumption in the world. The earliest energy in human history is biomass energy. Before the second half of the 19th century, the energy used by humans was mainly paid firewood.
    The method of using biomass energy is: (1) to make biogas. Mainly use urban and rural organic waste, straw, water, and human and animal manure to produce flammable gas methane through anaerobic digestion for life and production. (2) Use biomass to make alcohol. In the current world energy structure, the proportion of biomass energy is small.
    3. The use of ocean energy refers to the use of certain methods and equipment to convert various oceans into electrical energy or other available forms. Because the ocean can have the advantages of renewable and non -pollution environment, it is a strategic new energy source that needs to be developed.
    4. Geothermal Energy [Energy] is a natural thermal energy extracted from the crust. This energy comes from the lava inside the earth and exists in the form of thermal force. It is the energy that causes volcanic eruption and earthquake.
    The temperature inside the earth is as high as 7000 ° C, and at the depth of 80 to 100 miles, the temperature will drop to 650 to 1200 ° C. Through the flow of groundwater and lava to a crust from 1 to 5 kilometers from the ground, thermal force was transferred to a place closer to the ground.
    The high -temperature lava heats nearby groundwater, and these heated water will eventually seep the ground. The simplest and most cost -effective way to use the thermal energy of the land is to directly use these thermal sources and extract its energy
    5. Solar Energy refers to the three ways of heat radiation (see thermal energy transmission (see thermal energy transmission, which : Radiation), the main manifestation is the sunlight that is often referred to. In modern times, it is generally used as power generation or provides energy for water heaters.
    since the birth of life on the earth, it has mainly survived with thermal radiation energy provided by the sun. Since ancient times, human beings have also understood that it has been dried with sunlight and used as a way to make food, such as salt and salted fish.
    In the increasingly reduced fossil fuel, solar energy has become an important part of human energy use, and has continuously developed. The use of solar energy has two ways: light thermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in the broad sense also includes wind, chemical energy, and water energy on the earth.
    6. The kinetic energy generated by wind energy flow. A form of transformation of solar energy. Due to the uneven heating of the surface of the earth due to solar radiation, the pressure distribution in the atmosphere is unbalanced. Under the action of the horizontal air pressure gradient, the air forms wind along the horizontal direction.
    The total reserves of wind energy resources are very huge, and the energy developed in the year is about 5.3×10^13 kWh. Wind energy is renewable clean energy, with large reserves and wide distribution, but its energy density is low (only 1/800 of water energy), and it is unstable. Under certain technical conditions, wind energy can be developed as an important energy source.

    The definition of new energy

    1980 The “United Nations New Energy and Renewable Energy Conference” held in the United Nations in the United Nations: The foundation allows traditional renewable energy sources to be modernized and utilized, and the use of renewable energy replacement resources with limited renewable energy replacement resources and pollution of the environment are used for the development of solar energy, wind energy, biomass energy, and tidal energy energy for the environment. , Geothermal energy, hydrogen energy and nuclear energy.

    New new energy generally refers to the renewable energy sources developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean flow and tide energy, and marine surfaces The heat circulation with the deepness, etc. In addition, there are hydrogen energy, biogas, alcohol, methanol, etc., and the energy of coal, petroleum, natural gas, and water energy that have been widely used is called conventional energy sources.
    The new energy sources that are increasingly valued by countries with environmental protection and renewable new energy with environmental protection and renewable new energy.
    The new energy sources that can form industries in China mainly include water energy (mainly referring to small hydropower stations), wind energy, biomass energy, solar energy, geothermal energy, etc. It is a clean energy that can be used. The development of the new energy industry is not only an effective supplementary method for the entire energy supply system, but also an important measure for environmental governance and ecological protection. It is the ultimate energy choice that meets the needs of sustainable development of human society.
    Generally speaking, conventional energy refers to the technology that is relatively mature and has been used in large scale, and new energy usually refers to energy that has not been used in large scale and is actively researching and developing. Therefore, coal, petroleum, natural gas, and large and medium -sized hydropower are regarded as conventional energy, and solar energy, wind energy, modern biomass energy, geothermal energy, ocean energy, and hydrogen energy are used as new energy sources.
    In the establishment of technology and the concept of sustainable development, industrial and living organic wastes that have been regarded as garbage have been re -recognized in the past. Utilization, therefore, the resource use of waste can also be regarded as a form of new energy technology.
    The energy and resources that are only developed by humans and need to be further studied and developed are called new energy sources. Compared with conventional energy sources, new energy has different content in different historical periods and scientific and technological levels. In today’s society, new energy usually refers to solar energy, wind energy, geothermal energy, hydrogen energy, etc.
    This can be divided into: solar energy, wind energy, biomass energy, hydrogen energy, geothermal energy, marine energy, small hydropower, chemical energy (such as ether -based fuel), nuclear energy, etc.

    In August 1981, after the United Nations New Energy and Renewable Energy Conference was held in August 1981, the names of such energy sources were different, but the common understanding is that except for conventional fossil energy and nuclear energy, other energy sources can be called it. For new energy and renewable energy, it mainly refers to wind energy, solar energy, geothermal energy, tidal energy, ocean energy, biomass energy, hydrogen energy and water energy.
    The “Renewable Energy Law of the People’s Republic of China” stipulates that renewable energy refers to wind energy, solar energy, water energy, biomass energy, geothermal energy, ocean energy, etc. Among them, biomass energy refers to the energy sources of transforming plants, feces and urban and rural organic wastes in nature.
    The new energy department under the National Energy Administration of China, which is responsible for solar energy, wind energy, hydropower and other affairs, and is listed with the nuclear power division.
    is the new energy sources, and there is no specific conclusion at this stage. However, the international community generally believes that nuclear energy is not new energy.
    In addition, the international community excludes nuclear energy outside the CDM transaction (clean development mechanism). The “World Energy Outlook” report released by the International Energy Agency every year also lists nuclear energy separately.
    The various forms of new energy are directly or indirectly from the thermal energy generated by the deep inside the sun or the earth. Including solar energy, wind energy, biomass energy, geothermal energy, nuclear aggregation, water energy and ocean energy, and the energy generated by biofuels and hydrogen derived from renewable energy. It can also be said that new energy includes various renewable energy and nuclear energy. Compared with traditional energy, new energy generally has the characteristics of less pollution and large reserves. It is of great significance to solve the problem of depletion of environmental pollution problems and resources (especially fossil energy) in the world today. At the same time, due to the uniform distribution of new energy sources, it is also of great significance to solve the war caused by energy. According to the world’s assertions, resources such as oil and coal mines will be accelerated. Nuclear energy and solar energy are about to become the main energy sources. New Energy
    The United Nations Development Planning Department (UNDP) divides new energy into the following three categories: large and medium hydropower; new renewable energy, including Small-Hydro, solar energy, wind energy (Wind) , Modern Biomass, geothermal energy (), Ocean (tidal energy); traditional biomass energy (biomass).
