1. It is urgent to save electricity

Students in the journalism department of a university conducted a survey on wasteful behavior on campus. According to incomplete statistics, the amount of electricity wasted in schools in a year is 133,682 kilowatt-hours, which is enough for an ordinary family to use for 58 years. Colleges and universities are the units with the largest population. For such a large unit, the utilization of resources in all aspects is quite high, especially electricity consumption, which is quite staggering. For this reason, colleges and universities should include electricity conservation in their long-term development plans. The school's leadership organization and relevant departments should first strengthen their own awareness of saving electricity, understand the various methods and approaches of saving electricity, and strive to make the right choice for the long-term development of the school. Saving energy is not something that happens overnight. The problem of saving electricity in schools must be viewed from a long-term perspective.

As an educational base for cultivating higher talents, colleges and universities should cultivate the quality of students in an all-round way. Energy saving and consumption reduction is a real educational example.

A. Choice of electricity.

For now, although mains electricity is no longer as expensive as before, it is still overwhelming for large electricity consumers. Compared with various ways of using electricity, solar power generation systems have considerable advantages in systems with huge power consumption, such as university factories.

Take solar lamps for example. First of all, solar lamps use solar photoelectric conversion to provide electrical energy, which is inexhaustible and inexhaustible. Secondly, solar energy is a green energy, environmentally friendly and pollution-free, which is in line with my country's current development theme of promoting green environmental protection. Third, the electricity generated by solar energy is low-voltage direct current, so safety accidents such as electric shock and fire will never occur. Fourth, solar energy installation is convenient and simple. There is no need to set up additional wires. It can be used spontaneously on the spot, avoiding unsafe and inconvenient factors caused by construction. Fifth, a one-time investment is equivalent to a long-term investment in AC power. A one-time investment can be used in the long term. Generally speaking, solar power generation has a 25-year warranty, which reduces labor costs, maintenance costs and expensive electricity bills compared to AC power.

In view of the long-term development of colleges and universities, bringing solar energy into colleges and universities is the best way to save electricity. First of all, it can be changed from street lights. All school street lights can be changed to solar street lights. Solar street lights have high luminous efficiency, high brightness, long service life, energy saving, economy, environmental protection and practicality. It can be used for 3-7 days on a single charge, which solves the problem of electricity consumption caused by rainy days. You only need a one-time investment in solar street lights, and you can sit back and relax for 25 years. In addition, you can try to build a solar power station. According to the design, the electricity generated can be used for normal lighting and daily electricity consumption of the entire school.

B. Selection of light source.

All the light sources in the school can be changed to high-efficiency LED green light sources, which can effectively save a lot of power resources. LED light source is a light-emitting device made of semiconductor chips. It has significant advantages such as high luminous efficiency, low power consumption, long service life, low operating temperature, strong safety and reliability, fast response speed, and green environmental protection. After testing, under the same brightness, the power consumption is only one-tenth that of incandescent lamps, but the lifespan is 50 times that of incandescent lamps and 20 times that of fluorescent lamps.

C. Mobilization of teachers and students across the school.

To carry out comprehensive education on electricity conservation, every student and teacher is required to start from themselves and start from small things around them to save every kilowatt hour of electricity: turn off lights when people leave, turn off lights in time and cut off the power supply. Integrate electricity conservation into the comprehensive quality evaluation of students and teachers, and fundamentally change the situation of students and teachers wasting electricity. All teachers and students in the school are called on to mobilize and collectively contribute their share to save electricity and build a green and sustainable society.

2. Save water and prevent water pollution, start from scratch

In teaching buildings and dormitory buildings, we can often see trickles of water flowing. Our investigation shows that if the average amount of water wasted in a teaching building is 2945.2 tons, based on this calculation, if there are 13 teaching buildings in the main campus, 38287.5 tons of water will be wasted; the average amount of water wasted in dormitory buildings is 571.7 tons. If there are 29 dormitories on the main campus, the total waste amount is 16,578.7 tons. If one ton of water costs 6 yuan, the school wastes as much as 320,000 yuan in water bills a year.

Saving water resources and preventing pollution should start from every step in life:

1. Turn off the faucet as soon as you use it to avoid long running water

2. Check the faucet in time Maintenance to avoid water waste caused by equipment damage

3. Use water for multiple purposes, use water for washing clothes to flush toilets; use water for washing face to water flowers, etc.

4. Use water for washing clothes without water Phosphorus washing powder to reduce pollution

5. Keep the rinsing water to use as washing water for the next batch of clothes

6. Use detergents with caution and use soap as much as possible to avoid water pollution.

7. According to statistics, sanitary water accounts for about 70% of everyone’s water consumption. Schools can change water equipment in bathrooms, boiling rooms, etc. to water-saving types

8. The faucet is changed from a full-turn type to a 1/4-turn type. By shortening the time of turning the faucet on and off, the amount of water loss can be reduced

9. The school bathroom can use a low-flow nozzle or add a new one to the original nozzle. The slow-flow water device effectively ensures water demand and reduces the flow of water

3. Save paper and protect forest resources

Nowadays, college students waste an alarming amount of paper. During the job search process, a large amount of paper was turned into thick resumes. According to statistics, the paper that can be produced by cutting down a 5-year-old poplar tree is only enough for 3 students to apply for jobs. In addition, only one side of the paper is used now, and a large amount of paper will be thrown into the wastebasket after writing and scratching on one side. Students' homework and graduation thesis now need to be printed out. , and they are all single-sided. If one sheet is crooked or slightly unclear, it will need to be reprinted, thus doubling or even more paper is wasted. We can save paper from the following aspects:

1. Advocate multiple uses of one sheet. You can accumulate single-sided papers with printing errors or a little content and bind them into a book for drafting. Use;

2. When teachers assign homework, if it can be expressed in documents, try not to print it, and promote the widespread use of electronic documents;

3. Waste materials can be used Sort the paper, or use it for secondary use, or sell scrap to reduce waste;

4. Save every grain of food and develop a good habit of diligence and thrift

"College students themselves The investigation exposed the shocking waste of campus canteens, which dumped an acre of grain a week." Faced with these shocking figures, everyone needs to ask themselves: "Why should we waste it?" Because after spending money, we can do whatever we want? The money is yours, but the resources belong to everyone! No one has the right to waste! When you dump the food into the trash can, it constitutes disrespect for other people's labor, and it is a waste of your parents' hard work.

In just one week, rice equivalent to one acre of land was thrown away, indicating widespread waste. However, what is more terrifying than the phenomenon is the students' indifference and extreme lack of awareness of conservation. As a contemporary college student, as the leading force in the future development of the motherland, high-quality talents who have received the education since childhood that "it is noon on the day of hoeing, and the sweat is dripping on the soil, but who knows that every grain of rice on the plate is hard work", are actually ignorant And numb to such an extent!

First of all, schools need to formulate practical rules and regulations to conserve resources, put conservation into action, and include it in the ideological and moral evaluation of students.

Secondly, the school can organize a special "Thrift Group" to conduct powerful graphic publicity or artistic performances on campus waste and conservation.

Third, various lively and interesting slogans about "Thrift is a virtue, waste is a shame" and related slogans can be hung in the canteen to remind students and teachers who come to dine at all times: labor Results cannot be wasted.

Fourth, as a college student, we cannot regard saving as a trivial matter. Zhuge Liang said: "Quietness is used to cultivate one's moral character, and frugality is used to cultivate virtue." Diligence and frugality are the necessary conditions for a person to cultivate one's moral character and cultivate virtue. This is especially true for college students.

Finally, commend and reward classes and individuals who are thrifty and effective, and call on all teachers and students to establish a sense of thrift and develop a good habit of thrift.

Thrift has always been a traditional virtue of the Chinese nation.

Saving to get rid of poverty is a kind of instinct; saving to form a habit is a kind of perseverance; saving to form a culture is a virtue; saving to build a civilization is a kind of character; saving to promote social development is a kind of character. Such an unshirkable responsibility!

5. Eliminate the use of disposable items and reduce white pollution

Disposable items bring short-term convenience to people, but bring disaster to the ecological environment; they accelerate the development of the earth The depletion of resources also brings environmental pollution to the earth. Schools can adopt the following methods to eliminate disposable items and reduce white pollution:

1. The school’s supermarkets or stores should strengthen control over the use of plastic bags. Plastic bags may not be provided or provided for a fee to a certain extent. to reduce white pollution.

2. When dining in canteens, you must bring your own tableware. Canteens are prohibited from providing plastic bags, disposable chopsticks, lunch boxes, etc. to diners.

3. Now in college campuses, Walkmans, CDs, MP3s, Wenquxing, etc. have become essential items for college students, and the battery consumption is also very large. Usually, students throw used batteries directly into the trash can, which sometimes leaks toxic liquid and causes potential pollution to the environment. Rechargeable batteries can be used instead of ordinary batteries, so the pollution caused by batteries can be easily reduced.

4. Use handkerchiefs instead of paper towels, porcelain cups and glass cups instead of paper and plastic cups, and mechanical pencils instead of wooden pencils.

5. Each class will establish a small garbage point in the class, and the garbage will be collected according to five categories: paper, plastic, metal (such as cans, etc.), batteries, and other categories. Due to the large amount of paper and plastic, they can be cleaned once a day. In addition, considering the harm of batteries to the environment, it is recommended that students recycle used batteries.

6. The school has set up several large trash bins to recycle the garbage in the classified trash bins of each class, and set up more small classified trash bins on campus. The school is responsible for contacting social recycling units and sending out recycled garbage in a timely manner.

7. The school should set up a scoring system to encourage classes that perform well in garbage recycling. Recycled revenue can also be returned to each class for use.

It should be noted that if we want to fundamentally eliminate white pollution on campus, we must establish the concept of environmental protection in the minds of students

. Therefore, it is recommended that schools strengthen environmental education, such as collecting environmental protection materials logo, carry out environmental protection writing contests, hold environmental protection singing competitions and other activities to make environmental protection awareness deeply rooted in the hearts of the people.

The purpose of strengthening environmental education for students is also to promote environmental protection knowledge to the whole society. Therefore, it is recommended that schools carry out public welfare activities to the society in various aspects
