What will be the future energy era It is best to connect from the past to the future

Human ancestors in primitive societies used natural fire, and later gradually learned to make fire from flint; After a period of time, mankind discovered the first fossil fuel--- coal, and then used the most sought-after fossil fuel --- oil, and mankind entered the fossil fuel energy era; With the continuous progress of society, human beings will develop in the direction of clean and efficient, and wind energy, tidal energy, nuclear energy, solar energy, and bioenergy have the most development potential. However, wind energy and tidal energy are random and should not be controlled; Nuclear energy and solar energy are now the focus of energy and will occupy an important position in the future; The continuous improvement of biotechnology has made bioenergy have a lot of room for development, but there are also great challenges. (One additional word:.)

Electricity is a secondary energy source. ）

In the past, the wood, stone, and iron ages can be said to be the age of tools, and the feudal society began to use water energy, wind energy, and then the steam engine drove the age of thermal energy. In the era of electric energy, oil I think belongs to bioenergy, (the result of paleontology) and then the 20th century, nuclear energy, morning energy, solar energy, so to speak, the energy we need is inseparable from the sun. So the energy of the future should also be related to the sun.

I myself think that it is from particles (molecules, atoms, neutrons, electrons, etc.).) to get energy. It's a bit like the atomic energy of now!

In the long run, nuclear fusion is a promising and almost endless source of energy for the future. Building on the future achievements of nuclear physics, mechanical engineering, together with other engineering technologies, to complete the development and diffusion power plant in the 21st century may completely solve the world's energy problems. The use of this new energy source can also reduce carbon dioxide emissions to the atmosphere.

Metal deposits in the earth's crust and seawater are extremely abundant. As long as the mining and beneficiation technology is improved and the performance of mining and beneficiation machinery is improved, so as to reduce the ore grade that can be economically utilized, and fully improve the metal waste, under the condition of sufficient energy, the metal material resources are not scarce. After coal, oil, natural gas, etc. are no longer used as fuels in large quantities and are mainly used as raw materials for synthetic materials, the quality of non-metallic materials can also be guaranteed in the long run.

Problem description: Please, please! ~~

I really don't understand! ~~

Analysis: The ocean – the energy treasure trove of the future.

With the progress of science and technology and the development of the times, a new era of ocean exploitation has arrived. Covering nearly two-thirds of the total surface area, the ocean contains a huge amount of energy that will be transformed into the energy of the future of humanity. The gorgeous volcanoes under the sea have become our thermal power plants.

Look at! Robots are collecting the tremendous energy emitted by volcanoes, allowing volcanoes, which were once natural disasters, to live in harmony with us, thanks to the great wisdom of humans.

Wind power line.

Wind energy as an efficient and clean energy source is getting more and more attention, human beings have a long history of using wind energy, many countries have a long history of windmills, wind mills and other equipment to use wind energy. The wind-powered special line I designed is a future form of urban transportation built using wind energy, and the special line is a transparent tunnel, with an air outlet not far away, forming an air flow, and people in the future can drive wind-powered vehicles in a clean tunnel, which is really refreshing. Without the use of fuel, there will be no exhaust gases, and our cities will be free from pollution and become more beautiful.

Our homeland.

The earth is our home, look at the house we live in, it is the moon, the palace, the apple, the tree, ......The energy needed for electricity, heating and cooling in these buildings comes from geothermal energy from the Earth's interior.

Geothermal energy is the heat energy stored in underground rocks and fluids, according to scientists' calculations, the reserves of geothermal energy are equivalent to 100 million times the thermal energy of the earth's coal reserves, which can be consumed by human beings for tens of billions of years.

Energy is a topic that the whole world is concerned about, it is related to the survival and development of human beings, and the continuous development of energy will provide great impetus for human progress. However, we know that the whole world is facing such a problem: non-renewable energy sources are limited, we cannot rely on these can not always rely on them to ensure the survival of human beings, what energy energy will human beings rely on in the future to survive?

So we need to understand the resources that might be leveraged in the future.

In my opinion, the most likely energy sources to be used in the future are nuclear power and combustible ice, and although their extraction technology is still not very mature, they will definitely come in handy if one day the technical support is sufficient.

We enjoy the light and heat of the sun every day, and the sun is far away from us, so you can see how great the energy released by nuclear fusion is. Now, many countries are trying to collect this kind of energy, trying various methods, and building nuclear power plants in different ways, but the danger of this energy source is really great, and the damage caused by a nuclear leak is incalculable. So, its development is a technical problem, and if this problem is solved, it will be just around the corner to take advantage of it.

The same problem is also with the development of another energy source, which is combustible ice on the seabed. We know that it is also called a natural gas and water mixture, and if it is used, it will cause much less pollution than coal and oil, and its reserves on the seabed are also very large. If the technical problem is solved, it will certainly benefit humanity as well.

After all, the energy that can be used now is limited, and the development of new energy is our way out in the future, and we should use our own knowledge and technology to make our own efforts for this cause.

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 resources that have just begun to be developed and utilized or are being actively researched and to be promoted, such as solar energy, geothermal energy, wind energy, marine energy, biomass energy and nuclear fusion energy.

All forms of energy come directly or indirectly from the heat generated by the sun or the Earth's interior. These include solar, wind, biomass, geothermal, fusion, hydro and ocean energy, as well as energy derived from renewable energy sources from biofuels and hydrogen. It can also be said that new energy sources include various renewable energy sources and nuclear energy.

Compared with traditional energy, new energy generally has the characteristics of less pollution and large reserves, which is of great significance for solving the serious environmental pollution problem and resource (especially fossil energy) depletion 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 assertions, the reduction of oil, coal and other resources will accelerate.

Nuclear energy and solar energy are about to become the main energy sources. The United Nations Development Programme (UNDP) divides new energy sources into the following three categories: large and medium-sized hydropower; New renewable energy, including small hydropower, solar, wind, modern biomass, geothermal, ocean (tidal energy); Penetrates biomass energy.

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 researched and developed. Therefore, coal, oil, natural gas, and large and medium-sized hydropower are all regarded as conventional energy sources, while solar energy, wind energy, modern biomass energy, geothermal energy, marine energy, nuclear energy, hydrogen energy, etc. 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 waste, which has been regarded as garbage in the past, has been re-recognized, and has been deeply researched and developed as a material for energy resource utilization, so the resource utilization of waste can also be regarded as a form of new energy technology.

The energy resources that have recently been developed and utilized by human beings and need to be further researched and developed are called new energy, and 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, etc. According to the category, it can be divided into:

Solar energy, wind power, biomass energy, biodiesel, fuel ethanol, new energy vehicles, fuel cells, hydrogen energy, waste-to-energy, building energy efficiency, geothermal energy, dimethyl ether, combustible ice, etc.
