According to the different classification methods of energy, what kind of energy do electrical, nucl

In terms of the classification of energy generation, which can be classified as primary energy.

and secondary energy. among othersElectrical energy is a secondary energy source; Nuclear energy and solar energy are both primary energy sources. That is, electrical energy is an energy product that needs to be converted from primary energy processing.

Primary energy can be obtained directly from nature.

Classified according to the nature of the energy, which can be divided into fuel-based energy and non-fuel-based energy. among othersElectricity can be either fuel-based or non-fuel-based, depending on how it is generated. Nuclear energy and skylight energy are both non-fuel energy sources.

In terms of the classification of energy pollution, which can be divided into polluting energy and clean energy. Electricity can be either clean or polluting, depending on how it is generated. Nuclear energy and solar energy are both clean energy sources.

Conversion between energy generation:

1. Various forms of energy can be converted into each other, in the primary energy, wind, water, ocean currents.

and waves, etc., are based on mechanical energy.

kinetic energy and potential energy) can be utilized by various wind machinery (e.g., wind turbines) and hydraulic machinery (e.g., hydro turbines).

Converted to power or electricity.

2. Conventional energy sources such as coal, oil and natural gas are generally burned through combustion.

Converted into heat energy.

3. Thermal energy can be used directly, but a large amount of thermal energy is passed through various types of thermal machinery (such as internal combustion engines, steam turbines and gas turbines.

etc.) to convert into power to drive all kinds of machinery and transportation to work; Or drive the generator to send electricity to meet the needs of people's life and industrial and agricultural production.

4. The energy required for power generation and transportation accounts for a large proportion of total energy consumption. According to **, by the end of the 20th century, the energy demand for electricity generation alone will be greater than 40% of the primary energy development. The greater the proportion of the primary energy converted into electricity, the higher the degree of electrification, the more advanced the productivity, and the higher the standard of living.

The above content refers to Encyclopedia - Energy.

There are many ways to classify energy, and it is divided into conversion processing.

Primary energy. And.

Secondary energy. Nuclear energy and solar energy are directly obtained from nature and belong to primary energy, while electrical energy is obtained through processing and conversion, which belongs to secondary energy.

The energy sources on Earth can be broadly divided into the following categories:

Energy type: Energy is classified by period, form, characteristic, or level of conversion and utilization. World Energy Council recommended categories: Solid fuels, liquid fuels, gaseous fuels, hydro and nuclear energy, electrical energy, solar energy, biomass energy, wind energy, marine energy and geothermal energy.

Primary energy: energy obtained from nature without any change or conversion, such as **, raw coal, natural gas, biomass energy, hydropower, nuclear fuel, as well as solar energy, geothermal energy, tidal energy, etc.

Secondary energy: The energy obtained by processing or converting the primary energy, such as gas, coke, gasoline, kerosene, electricity, hot water, hydrogen energy, etc.

Conventional energy: energy that has been produced and widely used on a large scale under the current economic and technological conditions, such as coal, oil, natural gas, hydropower, and nuclear fission energy. Compared with new energy, new energy refers to the systematic development and utilization of energy in new technologies, such as solar energy, marine energy, geothermal energy, biomass energy, etc. Most new energy sources are natural and renewable, and are the foundation of a lasting energy system in the world of the future.

Commodity energy: energy consumed in large quantities as a commodity circulation. At present, there are five main types: coal, oil and gas, hydropower, and nuclear power.

Non-commodity energy:

On-site use of fuelwood, agricultural waste and other energy sources. Usually renewable.

Environmental energy: The energy flow stored in the earth's environment, solar energy, radioactive sources within the earth, and the operation of the solar galaxy are the initial energy sources for all environmental energy in the world.

From the mode of generation, it can be divided into renewable energy and non-renewable energy.

Renewable energy sources include wind, solar, geothermal, nuclear, tidal, bioenergy, etc., and non-renewable energy sources are fossil fuels!

Energy is the substance that provides energy conversion to nature There are five categories (mineral energy, nuclear physical energy, atmospheric circulation energy, geographic energy, bioenergy)!

The new energy state mill sources include nuclear energy, solar energy, biomass energy, marine energy, geothermal energy, hydrogen energy and wind energy.

New energy is also known as unconventional energy. It refers to various forms of energy in addition to traditional energy sources. It refers to the energy that has just begun to be developed and utilized or is being actively researched and promoted.

New energy generally has the characteristics of less pollution and large reserves.

Answer C Nuclear energy, hydrogen energy, and solar energy are all new energy sources, so item C is in line with the topic

Energy can be divided into renewable energy and non-renewable energy according to whether it is renewable or not.

Renewable energy refers to non-fossil energy sources such as wind, solar, hydro, biomass, and geothermal, which are clean energy. Renewable energy is a green and low-carbon energy source and an important part of China's multi-wheel drive energy system, which is of great significance for improving the energy structure, protecting the ecological environment, responding to climate change, and achieving sustainable economic and social development.

Non-renewable energy refers to the energy that has been formed in nature for hundreds of millions of years, cannot be restored in the short term, and with large-scale development and utilization, the reserves are getting smaller and smaller, and there is always a day of depletion. Including coal, **, natural gas, oil shale, nuclear energy, etc.

Definition of energy:

Energy source, also known as energy resources or energy resources, is an important material basis of the national economy, and the future fate of the country depends on the control of energy. The degree of development and efficient use of energy and per capita consumption are important indicators of production technology and living standards. (Encyclopedia of China, Mechanical Engineering Volume).

In the Energy Conservation Law of the People's Republic of China, the term "energy" refers to coal, oil, natural gas, biomass energy, electricity, heat and other resources that obtain useful energy directly or through processing and conversion.

Energy development:

Over the years, China's energy market-based pricing reform has made significant progress, and price adjustment has gradually become transparent. It is expected that in 2013, the new mechanism of refined oil pricing will be launched, the pilot reform of natural gas will be expanded or pushed to the whole country, and the linkage of coal and electricity is expected to be further promoted.

Over the years, the National Development and Reform Commission has repeatedly emphasized that the new refined oil pricing mechanism is expected to be "introduced at the right time". Market participants generally believe that when international oil prices and domestic inflation are low, it is a good time for the new mechanism to be introduced.

3. In addition, the opportunity for coal prices to merge has come. The National Development and Reform Commission has set the tone for the convergence of coal production and transportation needs in 2013, and the core policy package includes three points: the first cancellation of key coal contracts; For the first time, the allocation of railway capacity was liberalized; We will continue to improve the coal-electricity linkage mechanism.

4. At the same time, the report on canceling key contracts and promoting the integration of thermal coal led by the National Development and Reform Commission has been reported. In addition, for the 2013 coal-fired power contract negotiations, the National Development and Reform Commission has solicited opinions on the "Guiding Opinions on Deepening the Market-oriented Reform of Coal and Doing a Good Job in Connecting Coal Production and Transportation Demand".

According to the technical status of energy utilization, it can be divided into conventional energy and new energy.

Conventional energy refers to energy that has been used for many years and is still being used on a large scale. Such as oil, coal, hydropower, bioenergy, etc.

New energy refers to energy sources that have only begun to be used by human beings in recent years, such as nuclear energy, solar energy, and marine energy; Or it has been used in the past, and then it has been replaced, and now there is a new way of using energy, using wind energy to generate electricity.

With the exception of geothermal, tidal and nuclear energy, all other energy sources on Earth come from solar energy;

Water is evaporated by heat because of the sun's irradiation, water vapor follows the movement of the atmosphere, condenses and falls to a high place, and then flows from a high place to a low place to form a water flow, which produces water energy in the process, so its essence also comes from the energy of the sun, so b is in line with the topic

Therefore, choose B
