FAQ

What is a one-time energy

Primary energy, also known as natural energy, refers to the use of natural resources that have not been changed or changed. Such as coal, crude oil, natural gas, water, wind energy, solar energy, ocean energy, tidal energy, geothermal energy, natural uranium, etc.. Primary energy is divided into renewable energy and non renewable energy, the former refers to the repeated generation of natural energy, the latter with a little less, mainly all kinds of fossil fuels, nuclear fuel.

Mainly for PetroChina, Sinopec, the state-owned monopoly enterprises to discuss

So, what is "energy"? About the definition of energy, there are about 20 kinds. For example: the "Encyclopedia" of science and technology, said: "energy is from the heat, light and power and energy resources"; the "Encyclopedia Britannica" said: "energy is a include all fuel, water, sunlight and wind terms, humans can use appropriate means to make it provide the required conversion the energy for themselves"; "Japan encyclopedia" said: "in various production activities, we use energy, mechanical energy, energy and energy to work, can be used as the carrier of these various sources of power in nature, called energy"; China's "energy encyclopedia" said: "energy can be converted directly or by providing light, heat and power in any forms can be contained in energy resources needed for the human." It can be seen that energy is a source of energy in various forms.To be exact and simple, energy is a kind of material resources that can provide some form of energy for human beings.It is often referred to as sources of energy that can be used by humans to obtain useful energy.

State approved products called new energy foods

The difference between new resource food and health food:1 health food refers to food with specific health functions, and approval must also be clear that what has a health care function, and the need for a health care function marked and defined on the product packaging, the new food resource has one or more functions are not on the product introduction mark in detail.2 new resources of food and health food for the application of the crowd is different, the former applies to any population, while the latter is suitable for specific populations.

How to solve the energy problem

Market economy is open, China should vigorously develop the international energy market, make full use of the international and domestic two kinds of resources, and expand the way and quantity of energy imports

What are the new energy sources?

Generally there:Superconductive material, solar cell material, hydrogen storage material, solid oxide battery material intelligent material, magnetic material, nano material.Several new energy and new materials in the futureWave energy: ocean wave energy. This is an inexhaustible, renewable energy without pollution. It is speculated that the earth's Shanghai ocean wave energy stored up to 9 x 104TW. In recent years, the utilization of wave energy has occupied a place in the country's new energy development plan. Despite the high cost of wave energy generation, the need for further improvement, but the current progress has shown the potential commercial value of this new energy. A wave power plant in Japan has been running for 8 years, although the cost of generating electricity is higher than that of other power generation methods, it can save the cost of power transmission and so on. Currently, the United States, Britain, India and other countries have built dozens of wave power stations, and are running well.

New energy technology applications, including the professional

New energy related to the following basic professional:1. Machinery, all kinds of mold, product development;2 HVAC (solar thermal power) heat pump system;3 Analysis and test of thermal analysis finite element analysis and the like;

What are the economic operating standards for energy equipment and systems?

Ten measures to build a resource-saving societyThe party's the fourth Plenary Session of the 16th CPC Central Committee through the "CPC Central Committee on strengthening the party's ruling ability construction decision" to "pay attention to family planning, to save resources, protect the environment and production safety, vigorously develop the circular economy and building a conservation minded society", as the important content of the party continuously improve the ability to control the socialist market economy, to further strengthen the party's ruling of our party capacity building, pointed out the direction. This is to accelerate the construction of resource-saving society, promote the development of circular economy, taking a new road to industrialization, to ease the bottleneck of resources, solve the well-off society facing resource constraints and environmental pressures, to ensure that major initiatives continued rapid and healthy development of the national economy, far-reaching significance.

What is the comprehensive calculation of energy production?

In order to comprehensively reflect the total energy production, various energy products must be calculated according to the different calorific value of the common conversion standards. In China, the standard coal is calculated, and the calorific value per kilogram of standard coal is 7 million.
