Power saving speech 1 We can enjoy the convenience brought by electricity every day, and almost all activities in the evening can't be separated from electricity. At present, electricity, whether from hydropower, nuclear energy or thermal power generation, is bought at a huge environmental and resource cost.
Hydropower facilities have changed the ecological conditions of rivers; Nuclear power plants export nuclear waste; Burning coal in thermal power plants produces a lot of harmful gases and dust, which pollutes the atmosphere, endangers human health, leads to acid rain, intensifies the global greenhouse effect and triggers a series of ecological and social crises. So the electricity we consume is not clean, nor endless, but limited, which has caused great pressure on the environment.
In recent years, most parts of our country are short of electricity, and power production can't keep up with the demand for electricity for production and life. We are very dependent on electricity, so we should save electricity and avoid unnecessary waste. So, how can we save electricity? Here, for some electrical appliances that we often use at ordinary times:
1. TV. When you use a TV set, whether it is a color TV set or a black-and-white TV set, the brightness should not be too bright and the volume should be as low as possible without affecting the viewing. In addition, do not switch frequently. Frequent switching not only wastes electric energy, but also shortens the service life of TV sets. For the vast majority of remote control color TV sets, some devices of the TV set are still working after being turned off, which consumes some electric energy, so we have to unplug the power supply after being turned off. Newspapers and TV have reported the news of TV explosion and burning several times. In addition to the quality problem of the TV, there is another important reason that the TV has not been unplugged.
2. Radio, tape recorder and DVD player. The most important way to save electricity is to stop the machine when people leave and unplug it when not in use, because these machines usually don't cut off the power when they are turned off, which will consume some electricity.
3. refrigerator. Be careful not to accumulate too much food in the refrigerator, otherwise it will hinder the circulation of cold air and lead to the refrigerator not cooling. There shouldn't be too little food in the refrigerator. If there is too little food in the refrigerator, it will lose air conditioning and waste electricity. Refrigerators should try to reduce the number and time of opening doors, and ordinary refrigerators should be defrosted in time except frost-free refrigerators. Pay special attention to dust the condenser regularly, so as not to affect the refrigeration effect and waste electricity.
4. washing machine. Try to concentrate on washing clothes. The clothes washed in the washing drum should be close to the maximum laundry amount, so as to reduce the number of laundry and improve work efficiency.
5. air conditioning. When the temperature is not too high, try to use natural ventilation without turning on the air conditioner. When using the air conditioner, the temperature can be adjusted to 27℃-28℃, which will consume electricity if the temperature is too low; Clean the filter regularly at ordinary times to keep the filter clean; Air conditioning is the most power-consuming, so don't turn it on and off frequently; According to the room area, the model to be purchased is determined, and the large cooling capacity causes power waste; Due to the principle of "cold air goes down and hot air goes up", the installation position of air conditioner should be high rather than low. In addition, air conditioners generally do not need to be equipped with a voltage regulator, because the voltage regulator is connected day and night, and the air conditioner is also quite power-consuming when not in use.
6. rice cooker. Electric cooker is a kind of electric cooking appliance with high power consumption. Because of its excellent heat preservation performance, when cooking food in the rice cooker, when the water in the pot boils, the power supply can be cut off and the waste heat can be used for heating for a period of time. If the rice is not cooked, you can turn on the power again. In this way, intermittent power supply can save electricity by about 20% to 30%.
7. electric fan. The larger the blade diameter, the higher the speed of the electric fan and the greater the power consumption. Under the condition of meeting the air volume, try to choose an electric fan with smaller blade diameter, and adjust the medium or low speed operation to save electricity.
8. electric light. Household electric lamps should use energy-saving lamps with high brightness and low power as much as possible. At present, the energy-saving lamps promoted generally can save electricity by about 20% to 70%. But we must use qualified high-quality energy-saving lamps produced by regular manufacturers. The existing incandescent lamps at home should be reasonably selected according to the use situation. For example, a smaller light bulb can be used in bathrooms and the entrance of buildings. We should also get into the habit of turning off the lights and not turning on unmanned lights.
In addition, some electrical appliances, such as computers, have standby function and can be set to standby state when not in use. All electrical appliances should be turned off and unplugged in time when not in use, which is both energy-saving and safe.
Save electricity from now on, from small things, each of us should form a good habit of saving electricity. Students should pay attention to observation and thinking, find out where electricity can be saved in daily life, and use their brains to think about how to save electricity. Each class can carry out thematic activities in this area, such as collecting electricity-saving methods and experiences, making handwritten newspapers, putting forward reasonable electricity-saving suggestions and sending a proposal to the society. Electricity is related to thousands of households, save electricity and benefit the country and the people! Let each of us start from me, save every kilowatt hour for common interests, and be the small master of an economical society.
Speech on saving electricity 2 Teachers and students:
Good Morning, everyone!
The electricity that brings us light and electricity is transmitted to the electric water heater, so that we can have hot water in winter or when we are tired. Let's have a good bath. What a pleasant thing! But we must not forget to save electricity. Let me talk about it.
In hot summer, we are all very hot, but when eating ice cream, we should not forget the air conditioner. It is the air conditioner that brings us coolness and enables us to fall asleep quickly at night. However, don't forget that air conditioning is one of the most harmful appliances. The temperature of the air conditioner is one degree lower, but it is cool, but it consumes a lot of electricity. Every time you turn it on, you save some electricity. So I suggest that the most suitable temperature for turning on the air conditioner is around 26 degrees, which is economical and cool, so go to sleep.
Lamps are also the most expensive. When I am free at home, I always turn on two headlights, but my father or mother always wants to turn off one light, so it doesn't consume electricity. I can't do this well. I want to learn from my parents. Another time, I left the light on until dawn, but I forgot to turn it off after school. Later, I kept the light on until school was over in the afternoon. Alas, the energy-saving lamp has become. Also, use incandescent lamps and energy-saving lamps as little as possible. If you have the conditions at home, you can use new LED lights, which will save a lot of electricity. Our family has already used it first. If you haven't used it yet, try it! And the refrigerator. When children go to the store to buy cold drinks or ice cream, they should watch carefully before opening the refrigerator. Don't open the freezer before choosing, so the air conditioner will run and use more electricity. Don't do this for the children.
Start with me and save electricity. Start with the little things around you and actively participate in the earth's light-off for one hour!
Speech on saving electricity dear teachers and students,
Hello everyone!
From kerosene lamps to electric lights, from abacus to computers, electricity plays an important role in the process of creating modern civilization. Electricity has brought light, brilliance and hope to mankind.
Electricity comes from coal, oil, water and other resources. At the same time, electricity itself is also a resource. Even resources need to be saved. After all, we can't leave an empty living space for future generations.
"It's easy to turn off the lights at will, and many a mickle makes a mickle"; "Save one minute, one more minute." Power saving has become the focus of social attention, and it is also an important breakthrough in building a conservation-oriented society. The Design Standard for Energy Efficiency of Public Buildings clearly requires that all-glass curtain walls should not be built in new public buildings, and the glass curtain walls can only account for 70% of the walls at most, and the consumption of energy such as coal and electricity should be reduced during the use of buildings.
On the one hand, there is an extreme shortage of power resources, on the other hand, it is common for electricity to be wasted. Look at our daily life: do people turn on the lights, air conditioners and computers all night every day?
Saving electricity is the most important thing, so we should start from the details: turn off the computers and televisions that are dormant and let them "rest" completely; Choose energy-saving lamps to protect eyes and save energy; Adjust the temperature of the air conditioner to above 26 degrees, or turn off the air conditioner and enjoy the cool outdoors; Let your hair dry naturally after shampooing, instead of using a hair dryer; Reduce the number of times the refrigerator is opened, and don't put hot food in the refrigerator; The refrigerator should store a proper amount of food, 80% of the volume, to reduce power consumption; Wash clothes by hand, without or with less washing machine; Soak the washed rice for 10 minute, and then put it into a pot to cook; When watching TV, turn on 5 watt energy-saving lamp to avoid eye fatigue; Use more rechargeable batteries, less disposable batteries ... In fact, as long as you have the heart, you can save electricity instantly, and you can achieve it in the details!
The electrolytic crisis saved the earth. I believe that there will be one of you in the army of saving electricity!
Speech on saving electricity dear teachers and students,
Hello everyone!
As we all know, saving water and electricity is also an indispensable resource in our life, so we need to save. Now every household has electricity. Because of its popularity, many people don't know that saving electricity is also very important. At present, there are two mainstream power generation methods. One is to burn coal mines to generate electricity, and the other is to require us to use water conservancy to generate electricity, which will consume resources.
When you don't use electricity at ordinary times, turn off the power in time and don't waste it at will. For example, when there is no need to use electricity during the day, turn off the power without reminding, because everyone can do it. It's simple. Just raise your hand.
No matter at school or at home, we should pay attention to saving electricity, and don't think that we can spend money indiscriminately if we have already paid the money. Power resources are limited, and it takes a lot of equipment and manpower to supply so many people. If we waste it at will, it is the loss of resources, but when someone needs electricity, it will be gone, affecting many people. Power resources are as limited as water resources. Never think that these resources are endless.
There are no inexhaustible resources. If one day our coal is burned out and we can't generate electricity, if we encounter some other things that lead to insufficient power supply, then we will waste it at ordinary times and there will be no available power resources at critical times. I hope all students can learn to save money and don't waste it at will. When the last person left the classroom, we turned off the power switch conveniently. When we don't need electricity during the day, we should turn it off actively. No need to remind. Since you can do it, you should do it in time and cherish your own resources.
Although electricity is a renewable resource, it cannot be wasted at will. Waste means consuming funds, increasing the burden on society and the country, saving electricity and cherishing power resources. We will save a lot of renewable resources, and we can't be unwilling to do it just because it is a trivial matter. We should form the habit of saving electricity, cherish these resources, and don't waste or consume them at will. Only by using these resources in key areas can we show stronger strength.
If each of us uses electricity at will every day, think about how many people there are in our country and how much electricity we need to waste every day. We need to save electricity, not only for ourselves, but also for our family and friends to know how to save electricity. From now on, start with us, and then lead people around us to be prepared to save electricity instead of wasting resources. Let's learn to save electricity and let everyone know the benefits of saving electricity.
Thank you!
Speech on saving electricity 5 students:
We cannot live without electricity every day. With electricity, machines can rotate, weave and irrigate; With electricity, the lights will light up, the radio will ring and images will appear on the TV screen; With electricity, you can make phone calls and send telegrams ... electricity is so useful, do you know where it comes from?
Electricity comes from a generator. Take thermal power generation as an example. Coal miners dig coal from underground, and trains and ships transport coal to power plants. Workers in power plants grind coal into pulverized coal, and then send the pulverized coal to a high boiler, which burns the water in the boiler into steam, and the steam drives the turbine, which drives the generator, thus generating powerful electricity. You see, how many workers' uncles' painstaking efforts are condensed by each degree of electricity!
Do you know the function of primary electricity? The demand for primary electricity is increasing. Although the power industry has developed rapidly and the power generation has increased significantly, it still cannot keep up with the demand. So how to solve this problem? On the one hand, electric workers fight day and night to generate more electricity and supply more power, on the other hand, they should vigorously save useful electricity.
How do students save electricity? First of all, we should form the good habit of turning off the lights at home or at school. On the other hand, we should pay attention to the safety of electricity use: don't shake poles and wires; Don't fly kites near high-voltage lines; Don't throw anything on the wire; Don't pick up the fallen wires; Don't touch electrical appliances with wet hands. Otherwise, it may cause serious accidents, waste a lot of electricity and endanger life.
Students, let's take practical actions to save electricity and support socialist construction!

Hello everyone!
We have no electricity every day. With electricity, machines can rotate, spin and irrigate; With electricity, the lights will light up, the radio will ring and images will appear on the TV screen; With electricity, you can make phone calls and send telegrams ... electricity is so useful, do you know where it comes from?
Electricity is sent by the sender. Take thermal power generation as an example. Coal miners dig coal from the ground and then transport it to the power plant by train/ship. Workers in power plants grind coal into pulverized coal, and then send the pulverized coal to a high boiler, which burns the water in the boiler into steam, which drives the steam turbine, which drives the generator to generate powerful electricity. You see, every degree of electricity embodies the hard work of many workers' uncles!

Save electricity speech 7 teachers and students:
Hello everyone!
I am a classmate of XXX class, Chen Moumou. I read the news the other day that Haojiang District Education Bureau and Haojiang Power Supply Bureau jointly held a series of activities with the theme of saving electricity, using electricity safely and science of electricity. As the flowers of the motherland, we should also respond to the spirit of the district leaders' instructions and save electricity in our daily life.
So, how can we save electricity?
In fact, the practice is very simple. If you turn on the fan for one hour, watch TV for one hour and use the refrigerator air conditioner with high power consumption less every day, then every family can save 1 kwh, ten families can save1kwh and one hundred families can save1kwh. There are tens of millions of families in our country, which can save tens of millions.
What are the benefits of saving electricity?
I have studied the data and found that power generation consumes 400 grams of coal at a time, 100 degree power generation consumes 4000 grams of coal, and 100 degree power generation consumes 40 kilograms of coal. In this way, if every family saves electricity once a day, our country can consume many tons of coal less a day, which can save a lot of resources and will not cause great damage to the environment and ecology.
Therefore, saving electricity should start from me and every family.
Speech on saving electricity 8 Teachers and students:
Good Morning, everyone!
Water is the source of life and electricity is the messenger of light. Protect water resources, benefit future generations, save electricity once, save water tomorrow, start from me, save electricity, everyone is responsible!
Although the total amount of resources in China is huge, China is short of water and electricity due to people's waste of resources. Faced with this situation, as primary school students, have we considered what we should do to save resources?
The situation of school electricity consumption is also not optimistic: after class, when doing exercises, the fluorescent lamps in some empty classrooms are "on". After washing your hands, forget to turn off the tap switch; When washing the mop, the water flows into the river. Students, do you know how much electricity and water will be wasted and how much burden will be added to the school and the country? How many billions should the country invest behind the seemingly endless water flow? With the development of society and economy, the national electricity consumption is rising, and the power shortage has become a heavy burden that hinders the progress of China. Do we students have to add weight to the already heavy burden?
As future builders of the motherland, we should establish the concept of saving energy and cultivate the good habit of saving electricity and water from now on. To this end, the following initiatives were issued to all students:
1. Don't waste disposable electricity: go to a special classroom in class, and turn off the lights and fans in time when there is no one in the classroom. Usually, students are assigned to special places to take care of them. Take a look, which class has the strongest consciousness!
Don't waste a drop of water: after washing your face, hands and brushing your teeth, you must form the good habit of turning off the tap. If you see that the tap is not turned off, turn it off actively.
Let's create an environment-friendly and energy-saving life together!
Speech on saving electricity 9 students:
I believe everyone is familiar with electricity! It is inseparable from our life: household appliances need electricity, industrial production needs electricity, and neon lights on the street can't do without electricity ... we just live in a kingdom of electricity! Everyone should also know that in our populous country, if everyone wastes 1 kwh, we will waste more than one billion kwh. At present, many places are short of electricity, so saving electricity should be the code of conduct that each of us consciously abides by!
In real life, the phenomenon of wasting electricity is everywhere. Some students may say, "My family has plenty of money, and 1 kWh is only a few cents. Don't haggle over it." This idea is all wet, because every kilowatt hour we use is the result of hard work of workers. Electricity, through a series of special power generation equipment, converts various energy sources, such as coal, water power, wind power and atomic energy. Turn it into electricity, and then send it to every corner through various transmission and distribution lines. In order to build and maintain these electrical equipment and make it work normally, the workers have paid a lot of hard work. If electricity is wasted, it is not only the loss of national resources, but also the trampling on the achievements of electric workers.
Speaking of saving electricity, I think of one thing. One weekend morning not long ago, my mother went to the office to look up some information, so I followed her to the office building. I saw the whole building was quiet, but the hall was brightly lit. I took the elevator to the floor where my mother's office was located, and all the lights in the corridor were on. I asked my mother, "Why don't you turn off the light?" Mom said, "After so many years, nobody cares." I felt a little uncomfortable, so I said angrily, "You don't want to waste our electricity, so you don't care about the electricity here?" ""it's public anyway. " Mom said absently. That day, I ran up and down and turned off all the lights in the corridor on 1 1. My mother, who has worked in the office for many years, is amazed at what I have done.
In fact, if everyone can do these little things within reach, such as turning off the lights and not turning on the air conditioner, the electricity saved is a lot of wealth.
Students, from now on, let's work together to save electricity!
