In real life or work and study, when it comes to composition, everyone is certainly familiar with it. According to different genres, composition can be divided into narrative, expository, practical and argumentative. Do you know how to write a standardized composition? The following is the first day of the new energy composition compiled by Bian Xiao. Welcome to read the collection.
The first new energy composition 1
Walking on the streets of the 22 nd century, you will feel that this is a brand-new era. The development of new energy has promoted the further development of science and technology in the world.
Energy is the guarantee for the survival of mankind and the earth, but oil and other energy sources are becoming less and less, so finding new energy sources has become an important way out for mankind. The sea area on the earth is vast, accounting for the total area, so scientists focus on the ocean that can extract new energy. So what new energy can be extracted from the ocean to maintain human survival?
The development of this new energy has effectively alleviated the greenhouse effect and smog weather, which is very environmentally friendly, but everything has advantages and disadvantages, so this kind of energy should avoid high temperature. In the era of school newspaper, this new energy has replaced oil and become the most widely used resource in human life. Can you guess what this is?
Some people think it is coal-iron ore resources, but this kind of energy is natural gas. Yes, the new energy is marine hydrogen, that is, hydrogen extracted from the ocean. People use electrolytic water to extract hydrogen, which is more practical. Hydrogen from the ocean can produce metals, chemicals and daily necessities to serve the whole society. The density of hydrogen is very small, and the reaction with oxygen will generate heat.
In the new era, new energy, science and technology are constantly improving and society is constantly developing. We should also make full use of energy to serve the society and the world. Let's cheer together!
New energy constitutes the first part 2
Nowadays, environmental pollution exists all over the world, which is the result of human abuse of petroleum products. This consequence has become the focus of close attention of mankind all over the world. Now the living environment of human beings is getting worse and worse. Saving energy is the first and premise of environmental protection, and human beings should start from this aspect.
After investigation, I learned that all countries are studying a new energy source ―― environmental protection fuel cell. As far as I know, Germany is temporarily ahead of the world in this technology. This technology was originally used for military purposes, but now it is ready to be applied to aviation and civil use. Environmental protection fuel cell is characterized by no noise, no pollution and no radiation, and belongs to clean energy.
If this new type of environmental protection energy can be popularized in the world, it will be applied in all directions: vehicles, ships, airplanes and other similar means of transportation, construction machinery, lighting and so on. Therefore, pollution to air and water can be reduced. In addition, environmentally friendly fuel cells are easy to use and have many excellent characteristics, which will make great achievements in the field of environmental protection.
Although the environmental protection fuel cell has not been fully developed, once this technology is mature, we will promote it, so that all walks of life can use it, so that the environment we live in can reduce environmental pollution and benefit our mother earth, as well as ourselves and future generations! Let's look forward to the birth of environmentally friendly fuel cells in the future and our beautiful living environment.
Composition of New Energy Chapter 1 3
People can't live without electricity, which can be used for lighting, production, electricity, cars and trains. Electricity is widely used in life and production.
Electricity and water are called hydropower, coal is called thermal power and uranium is called nuclear power. But what should we do when water, coal and uranium are all used up? So people are looking for new energy sources.
1 0 June1day, my uncle came to my house. He is a graduate student in the Physics Department of Zhejiang University, majoring in new energy. What new energy? According to him, it is nuclear fusion. If the research is successful, we humans will have inexhaustible new energy. But I still didn't understand, so I looked it up on the computer. It turns out that all forms of new energy come directly or indirectly from the heat energy generated by the sun or the earth. Including solar energy, wind energy, biomass energy, geothermal energy, nuclear fusion energy, water energy and ocean energy, as well as energy generated by biofuels and hydrogen from renewable energy.
It can also be said that new energy includes all kinds of renewable energy and nuclear energy. Compared with traditional energy sources, new energy sources generally have the characteristics of less pollution and large reserves, which is of great significance to solve the serious environmental pollution and resource depletion problems 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.
It turns out that new energy has such a great effect on human beings that I will study hard and study hard in the future.
New energy synthesis Part I 4
I read an article today, only to know that there is a clean and pollution-free new energy-combustible ice.
This kind of combustible ice is formed by natural gas (methane) wrapped in water molecules and crystallized at low temperature and low pressure on the seabed. This white solid can release 64 cubic meters of methane gas and 3 cubic meters of fresh water at room temperature, and hardly produces any pollution. Now we are fully exploiting this combustible ice.
However, in the process of popularization, difficulties will follow. The first is the difficulty of excavation. At present, there are pyrolysis, depressurization and replacement methods, but these methods are time-consuming and inefficient. Secondly, the development of this new energy will inevitably encounter some resistance. How can those oil-rich countries watch their interests suffer in vain? Once this new energy source is successfully exploited, it will soon replace oil, so countries that started from oil will lose their main source of wealth, so they will definitely try their best to stop it. To say the least, even if this kind of energy is successfully developed, it will certainly become the goal of all countries out of bounds. Whoever grasps the new energy will grasp the lifeblood of the future world. How can this not cause competition? But this will certainly have many negative effects: national rebellion, war and so on. These hidden dangers cannot be ignored.
Nevertheless, developing new energy sources is our only way out in today's decreasing energy sources. I hope that new energy can spread to the whole world as soon as possible and open up a new road for the world!
New energy composition Chapter 1 5
The car condition can't satisfy my idea now. For example, it can't purify the air and protect the environment, let alone the car I imagined. It can purify the air and protect the environment. Next, let me introduce my car!
The bottom of the car is triangular and has stability; The car is semi-circular (slightly irregular) with transparent windows all around. The windshield wiper in front of the car is a hundred times faster than before. If it rains cats and dogs, it will be out of sight and will not affect the line of sight. There is also an automatic car wash function in front of the car, so you don't have to go to the car wash shop in the future; The tires of the car are also ten times harder than the previous tires.
The function of the car has also changed a little. There is an "automatic air sheet production machine" in the trunk of the car. Just put the "air sheet" into the "small cylinder", and the "small cylinder" will lead to the exhaust port along the pipeline, and then the air can be purified! There is a "water storage machine" next to the back window, and there are some dots next to the "water storage machine" to water the flowers when the water is full; In fact, these "waters" are not water, but rain. Whenever cats and dogs rain, the "water storage machine" will store rainwater, so this "water" is pure natural! There is an "oxygen tank" next to the skylight, and its exhaust port is at the front of the car. When oxygen comes out of the exhaust port, people can breathe fresh air.
It was my idea. You can also invent some interesting things in life. It may be different, it may be fun, it may bring happiness to people-come on!

Because people have exploited most of the energy in 2 1 century, there will be no energy available in the 23rd century. Fortunately, scientists have long predicted this result, and people can only use and have made full use of wind and solar energy to generate electricity.
Almost every city has the shadow of wind power and solar energy. On both sides of the street, people can often see the fragments of solar panels hanging on telephone poles. People can't look directly at high-rise buildings and houses with naked eyes, otherwise they will hurt their eyes, so they should wear protective glasses. Because the external walls of buildings are curtain wall glass that can store solar energy, most houses are flat, just like a hat. In order to better absorb solar energy, the glass on the roof can store solar energy and convert it into electric energy.
As soon as the sun rises, the solar washing machine starts to operate, and people's kitchens become clean. On rainy days, people can use the stored electric energy to cook rice and vegetables in the induction cooker. Cars don't use gasoline, but use solar energy to convert into electric energy and then into kinetic energy. The streets will never become smoky again because of exhaust gas. Our blue sky becomes blue and deep, the stream is crystal clear, and our shoes won't get dirty for a week. We all know that their present life was unexpected by their old ancestors, because in the previous videos, the blue sky was gray and there was always a black tail behind the car. At that time, we will cherish and cherish the world more.
New energy composition, top 7
On Saturday morning, I participated in a small class activity of photovoltaic power generation held by Hefei Evening News, and explored the mystery of new energy with my friends.
After an hour's drive, we came to a company called Sunshine Power. The staff said that their company is mainly engaged in new energy power generation, that is, using equipment to convert wind, sunlight, water and other energy into electricity. When it comes to electric energy, we can't help mentioning a machine called a sunlight reflector. The staff said that the electricity converted by solar panels cannot be used directly, and it is necessary to use a solar reflector to convert alternating current into direct current. Another most practical equipment is the new energy battery, which is mainly used in our current new energy vehicles, so that cars can run without refueling and use electricity to reduce the pollution to the atmosphere.
After visiting the company's small power station, the last link is that I have done experiments for a long time. At the teacher's command, we immediately sat down in our seats, and the experimental tools were already on the table. Don and I connect the solar panel, switch and light bulb with wires, so that the electric energy on the solar panel can be transferred to the light bulb, which makes the light bulb light up. Later, I also completed the machine assembly of wind power generation by myself. What is particularly happy is that the staff also prepared a small machine as a gift for us.
This activity is so interesting. I really came on a whim and had a good time. I will definitely attend next time.

In today's society, we mainly use oil and coal as energy sources. Oil and coal are non-renewable energy sources, so use a little less. In addition, using coal and oil will pollute the air and destroy the ecological environment.
Now we humans have realized this problem, so we have developed many high-clean new energy sources. Such as ocean energy, wave energy, tidal energy and wind energy.
Ocean energy is produced by the temperature difference of the ocean. Because the water temperature at the bottom of the ocean is very low, ammonia vapor is cooled back to liquid, and the high water temperature on the sea surface can make ammonia boil into steam, drive the turbine to rotate and start the generator. Wind energy is generated by the wind blowing the blades on the windmill. Because there is a generator in the windmill, the generated electricity can be transmitted to the power plant, which can also transmit electricity to everyone.
But if there is less water on the earth, the efficiency of ocean energy, tidal energy and wave energy is not high. The wind is very light in summer, so wind power generation is impossible. What shall we do? So, I thought of nuclear energy, which is very useful for human beings. We can use nuclear energy to generate electricity, because a very small amount of nuclear fission can release amazing energy. Because the metal shaft is a kind of nuclear fuel which is prone to fission reaction. The metal axis contains an axis atom, and the axis atom contains a nucleus. When the nucleus splits, it releases more energy. So we convert nuclear energy into the electricity we need.
Nuclear energy can replace ocean energy, tidal energy and wave energy. So it is the future "green energy" for mankind!

There are many energy sources in the world, such as solar energy, hydro energy, wind energy and electric energy. Now, every country needs energy. You see, some countries are arguing endlessly about energy, and some countries are ready for war for energy and want to plunder energy by force. This shows how important energy is. Because most of the TV universities we use now are developed and utilized with coal as energy; Most of the cars running on the street are driven by gasoline or diesel, which are extracted from underground oil; Most cooking at home uses gas and natural gas.
However, these energy sources are not infinite, and they will be exhausted one day, and this day is coming. If there is no energy, we can't take high-tech products such as cars, trains and planes; We can't watch TV, play computer or play games. What a terrible thing it is not to use lamps, lights and gas, so I want to invent a "micro-energy device". This energy device can collect all the energy of nature at any time and anywhere, and release it for everyone to use when we need it, so that with this energy device, there is no need for some countries to have wars over energy issues; Will not destroy the ecological balance between urban environment and nature; I won't see those wires as ugly as cobwebs in the street. And this energy device is very compact, easy to carry and very practical!
This is the "micro-energy device" I invented, which allows me to plug in the wings of imagination and generate infinite reverie.
Nowadays, vehicles cannot do without oil as fuel. They emit carbon dioxide every day, which not only destroys the ozone layer of the earth and raises the temperature of the earth, but also affects people's health and makes people lose many friends in nature. With the development of social economy, people's demand for all kinds of energy will increase. One day, they will be exhausted, and then we will not be able to survive. Therefore, I hope to use air as our new energy source in the near future.
I want to invent an engine that uses air as fuel. No matter any vehicle is equipped with this advanced engine, it can run without any fuel or electricity. Cars don't have to refuel anymore. Ships can sail at sea at will. After the plane flies into the sky, it suddenly finds that the fuel leaks or runs out, and there is no need to worry about accidents. There is no need for so many wires on the train.
Then everyone must think that they emit toxic waste gas, but they don't. They give off oxygen. The more oxygen they release, the fresher our air, the better our environment, the purer our sky, and many of our natural friends will thrive. In a word, with it, our earth will become more and more beautiful and the human body will become more and more healthy. I must study hard, work hard and try to realize this beautiful wish!

19 at 9: 00 am, the reporter of Mianyang Evening News arrived at the meeting place outside Hall A of the Expo on time. Although it has just opened, there is an endless stream of citizens and students who come to visit. Under the guidance of the teacher, we walked into the exhibition area of the World Expo with excitement.
A group of us interviewed in the new energy vehicle exhibition area, and the teacher told us that these new energy vehicles are all driven by electricity. Before we came to a bus made in Luzhou, the staff introduced it to us as a hybrid of oil and electricity. Power is used when the speed is less than 30 kilometers per hour, and it can travel 100 kilometers or more when it is over 30 kilometers, with a maximum speed of 69 kilometers per hour.
Then I visited a pure electric car, which can be charged directly with the plug-in board at home. It takes 8 hours to fully charge, while it only takes 2 hours to charge with a special charging pile.
A mini leisure scooter in the exhibition area attracted our attention. It has no door, probably because it is convenient to get on and off when going out to buy food and shopping. Its chassis is very low, and it is said to be modified according to go-karting. According to the staff, this car is very popular with the elderly.
New energy vehicles are powered by electricity, which not only saves gasoline, but also does not pollute the air with exhaust gas. Very low-carbon and environmentally friendly. If we all use new energy vehicles in the future, our sky will be bluer and the environment will be better.

Since I have a car at home, my father often takes me out to play, but as a teenager who loves environmental protection, the exhaust emitted by cars always worries me.
One day, my father said happily, "Finish your homework early today and take you for a ride tomorrow!" " "After hearing the news, I danced with joy, but-it's really convenient to drive out to play, but the emitted pollution gas is really annoying. Thinking about it is like a deflated ball, you can only refuse your father. Dad smiled and said, "it won't pollute the environment, because I changed to a green energy car!" "Take you to the garage!" As soon as my voice fell, I regained my vitality and ran quickly to the garage.
The car my father bought looks similar to the usual car, and the silver-white body shines in the sun. I opened the car door and sat in the co-pilot position. I felt left and right and asked my father, "Why do you say this car is a green energy car?" Dad answered me patiently: "In the past, the car at home burned engine oil, and there was always polluting gas when driving. This car is powered by electricity, just like a battery car. Although it doesn't run as far as before, it is environmentally friendly! " I nodded, thinking that this is the car I want!
Dad's energy car has become the baby of the family. With it, you don't have to worry about polluting the environment when driving! I hope more and more people can use this green energy car, so that we can all contribute to environmental protection.

Now there is environmental pollution all over the world, which is the result of the disadvantages of gradually popularizing the use of petroleum products. This consequence has become the focus of people all over the world. Nowadays, the environmental conditions in which people live are getting worse and worse.
