Energy saving and environmental protection my first composition 800 words

Chapter 1: energy conservation and environmental protection, I always thought that 'energy conservation and environmental protection' is far away from me. What can I do as a child? It was not until my uncle gave me a lesson on saving electricity that I learned that energy conservation and environmental protection are not only for adults, but also for children. Last summer vacation, I went back to my hometown in Hunan with my mother and stayed at my grandmother's house for half a month. It's hot, but it's good to have air conditioning. I'm blowing cool wind, eating ice cream and watching TV. It's really beautiful. Because of the hot weather, the air conditioner is on almost all day and all night. Only between 6:00 and 9:00 in the morning, grandma will turn off the air conditioner and open the window. One morning, I woke up hot enough to find that the air conditioner was off, so I lost my temper to my grandmother. The grandmother said, "silly child, if you turn on the air conditioner all day, you will get sick easily. You should open the window to have a breath of fresh air. Besides, we should also save electricity! 'I'm still not happy. I say grandma is a cheapskate. I turned on the air conditioner again, and my grandmother followed me. At noon, I play computer for a long time, so sleepy! Thought, take a nap first, then continue to play in the afternoon. The animation presses the 'pause' button and goes to bed. The computer doesn't turn off. It's only an hour or two anyway. After several times like this, my grandmother criticized me for not saving electricity, but I know that my grandmother loves me very much and won't be too fierce. One day, I was watching a cartoon. Suddenly, the screen was black. It turned out that there was a power failure. It's really inconvenient. It's hot and I don't have TV. The water has stopped. I'm so bored! In the evening, when my uncle came back from work, I asked him, "uncle, why do you have to cut off the power? "My uncle is an electrical engineer and works in the electric power bureau, so I asked as soon as he came in. My uncle said to us, "because the electricity consumption is too large, Zhuzhou has to limit the power supply, and each district turns off the electricity for several hours. 'I asked again:' is there little electricity? How does electricity come from? "My uncle worked in an electrical appliance factory in Hainan Province before he was a graduate student. It's a good question to ask him. He patiently told me a lot of knowledge, and gave me a 'thinking class'. It turns out that electricity can only be generated by burning coal and using water. The power plant can automatically adjust the power generation according to the size of the user's electricity. Electricity can't be stored. If a user turns on an extra lamp, a certain generator in the power plant will increase some power generation. The power consumption is too large for the power plant to generate so much power, so it has to supply power within a limited time. That's why we need to save electricity. There is also the need for coal, oil and water for power generation, so saving electricity means saving coal, oil and water resources. After listening to my uncle's words, I blushed. I used to waste too much electricity. However, from now on, I will certainly save water and electricity and do my part. From then on, I not only turned off the lights and computers in time, but also tried to persuade others to save water and electricity. One day, a little brother pressed every floor of the elevator, sat down from the first floor to the top floor, and then came down, and wanted to go up again. It was very interesting. When I saw it, I said, "Xiaoyi, it's a waste of electricity. It's also a waste of other people's time. I can't do this in the future! Let's play other games. "He took Xiao Yi to ride a bicycle. I went home and told my mother about it. My mother praised me and praised me for growing up. I thought to myself: This is what I should do, it's my responsibility, I don't need praise. Later, I will tell my classmates that we must save resources, because these resources are not much. Chapter 2: energy conservation and environmental protection I first sound that the word "environmental protection" seems very far away from us, but the decreasing of natural resources does happen around us. We must make some contributions to the earth, the mother who nurtures us. Zeng Jin, this beautiful planet is like a blue gem dotted in the vast space, so that all people who have seen her are proud of it. Now, the chimneys everywhere spit out black 'poisonous dragons', and the blue and clear river water has become very dirty. And the sky, once washed by water, is as clean as a spotless sky. Now, it is gray, like being one A layer of dirty plastic is covered; are we going to ignore it? Are we going to watch this once beautiful planet get dirty? Are we going to let the mother continue to haggard? no We should take action to help the earth return to the blue water and blue sky, let her skin - the earth no longer dry, let her blood - rivers and lakes no longer dirty, let our common mother - the earth rejuvenate. However, some people will say, how can we do it only by our own strength? But although one person's power is small, then all people together to protect this planet, our power is undoubtedly huge. Environmental protection is not a slogan on the lips, but everyone's responsibility and obligation. Environmental protection is not difficult. We just need to pick up the garbage on the ground, use more cloth bags, use less disposable items, and plant more trees & hellip; & hellip; only in this way, can our earth be cleaner, more beautiful and more comfortable. However, we can do more than that for mother earth. We also need to save energy. As we all know, the earth's energy is not inexhaustible. If we waste it like this, our future generations will have to face a resource exhausted earth. However, there are always so many people who are obsessed with the desire for profit and are blinded by the little interests. If we do not drain the resources of the earth, we will never give up. Think about it, do we save more for our children? Moreover, saving energy is also for our own sake! Take water resources as an example. From the perspective of the universe, the earth is a blue planet. The earth's water storage is very rich, with a total of 1.45 billion cubic kilometers, and 72% of its surface area covers water. But in fact, 97.5% of the earth's water is salty and bitter. It can't be drunk or irrigated, and it's difficult to be used in industry. There is only 2.5% fresh water that can be directly used by people for production and living. In the fresh water, nearly 70% is frozen in the ice sheet of Antarctica and Greenland, and most of the rest is the water in the soil or deep groundwater. Chapter 3: energy conservation and environmental protection first. Now our earth has been artificially damaged, and the earth is also facing the threat of 'death'. In this way, water sources are increasingly polluted, no longer beautiful, and human beings are no longer happy,. So we have to protect the earth from now on. Dianchi Lake is a beautiful scenic line and a symbol of Kunming. Every year, the gull flies from Siberia to Kunming to escape the cold. At this time, when you wander around the Dianchi Lake, you will hear the clear cry of seagulls and the happy and harmonious scene of people dancing with gulls, which is filled with every inch of air here. But now, Dianchi Lake is no longer as clear as it used to be. When you get here, you can only smell the stench. Although there are seagulls, there are not as many as before, and the human gulls no longer resonate with each other. Only the stench and the floating garbage on the water are left behind, which is the result of people's not caring for the environment. There are not a few of them today. In my hometown, there is a stream, the water is not as clear as people think, on the contrary, it is so turbid. Listen to grandma, once this stream was very clear, and the river channel was very wide. Under the sunlight, the stream water would like to sprinkle silver. Quietly, you can see the fish and shrimps in the water playing happily. Under the breeze, the water surface swings layer by layer Ripples, so calm, how wonderful the scene is! People in the village take him as drinking water. It is said that it is sweet. In summer, the land is covered with heat. Children often swim in the river and fight water wars. Laughter spreads all over the village. However, there was a time when people regarded this as a 'washing factory of nature'. Washing their clothes here, washing powder and stains washed into the river; at the same time, people also regarded it as' the garbage dump of nature ', constantly pouring domestic garbage into the river, filling up the river with accumulated garbage over time, making the originally broad river channel narrow. From then on, the village can no longer hear the beautiful "singing" of the stream, and no longer see the happy scene of fish and shrimp playing in the water. The merciless destruction of nature by human beings has made people no longer see the calm lake in the past. The charming scenery in the past is no longer a reality, but can only become a kind of beautiful memory for people. We can't continue to destroy the earth in this way. We should try our best to protect it. If we don't resist 20XX, it will become a reality. The earth has given birth to countless lives. This is the more beautiful earth. We want to think that the world without human beings was so peaceful and beautiful before, and then look at the present, so we should now Protect the earth, let countless creatures grow up happily, protect the earth is everyone's responsibility, do not let 20XX become the earth's wood day, at the same time, this is the extinction of human beings and all things.
