Building a solar energy city is a creative work that meets the requirements of the development of the times, implements the scientific development concept, and builds an environment-friendly and resource-saving society. It is a strategic decision made by the municipal party committee and the municipal government based on the current and long-term vision. It is a concrete action to promote scientific development, speeding up development, and harmonious development. It is also an important measure to enhance the image of the city and improve its comprehensive competitiveness.
First, building a solar city is an active exploration in keeping with the trend of the times. In the 21st century, human beings entered the era of ecological civilization, and the energy revolution must be accompanied by it. At present, the world's new energy industry is developing at a rate of more than 30% per year. Some scientists predict that by 2010, the world's photovoltaic industry will reach 10,000 megawatts. In 2030, photovoltaic power generation will account for 30% of the world's total power generation, 2050. Solar energy will replace more than 50% of conventional energy sources worldwide. If the 20th century is the oil century, then the 21st century is the century of solar energy. With the accelerated development of the solar industry, the pace of solar energy applications, especially solar lighting applications, has significantly accelerated. In recent years, many countries and regions have vigorously implemented the “Sunshine Plan†and have developed LED lighting plans (LED is the abbreviation of Light Emitting Diode), which is an internationally recognized next-generation solid-state lighting source with energy saving and high efficiency. Long life, environmental protection, no radiation and other significant features, its power consumption is only one-tenth of the traditional light source, life expectancy of up to 100,000 hours, the life of ordinary incandescent lamps is only 10,000 hours), such as: the United States "next-generation lighting "Light source plan", Japan "21st Century Lighting Research and Development Plan", EU "Rainbow Plan", South Korea "Solid State Lighting Plan" and so on. LED production applications represented by Japan, Europe, and the United States are growing at a rate of more than 40% per year. According to the US Department of Energy, by the year 2010, 55% of incandescent and fluorescent lamps in the United States will be replaced by semiconductor LEDs, saving $35 billion in annual electricity bills. China has officially launched the "National Semiconductor Lighting Project", and listed semiconductor lighting as a major project of the National Science and Technology Research Program of the "10th Five-Year Plan" and "Eleventh Five-Year Plan". Beijing plans to install 100,000 solar lights in one year, and solar lights in Shitai Express. In a sense, LED is the third revolution in human lighting after kerosene lamps and lamps. There is also a growing use of solar thermal energy into human production and life. The United States is implementing a solar "million roof" plan. 80% of households in Israel use solar water heaters. China's Texas, Hangzhou and other places have reached international advanced level in solar heating applications, and so on. We propose to build a city of solar energy, in order to comply with the trend of the times, take advantage of the trend, seize new opportunities, and create new advantages of Baoding.
Second, building a solar city is a concrete action to implement the scientific development concept. With the further development of the economy and society, the contradiction between our country's resources, environment and economic development and population growth has become increasingly acute, energy supply has become increasingly tight, and environmental quality has been declining. Experts have inferred that China's underground proven oil and raw coal reserves are only enough to be used for 30-50 years. China has become a major oil importer, endangering national security in the future and restricting the sustainable development of the economy and society. Not a solution to the point. Last year, the state also included the rate of decline in energy consumption per unit of production as a binding indicator in the 11th Five-Year Plan. To implement the scientific development concept and build an environment-friendly and resource-saving society, the first problem to be solved is how to develop and use renewable new energy sources and protect the ecological environment. This is a strategic issue that affects the sustainable development of a country and region. In the effective use of renewable energy, whether from the quantity of resources, the universality of distribution, or the reliability of cleanliness and technology, solar energy is superior to other renewable energy sources, and it is inexhaustible. Inexhaustible, pollution-free, cheap, energy that humans can use freely (the sun's energy per second is equivalent to 5 million tons of coal, and the energy projected onto the Earth's surface in 40 minutes is equivalent to the annual consumption of the world. The sum of energy. The solar radiation energy received by China is equivalent to the power generation of tens of thousands of Three Gorges projects. In fact, all the energy we use on the earth comes from the sun. Coal and oil are solidified solar materials. Direct use of solar energy is also a return to nature. The city of solar energy construction is to explore the feasible strategies for comprehensive utilization of solar energy, explore the feasible way to build an environment-friendly and resource-saving city, and pursue the harmony of economic development, social progress and ecological protection, human and nature. Reciprocal symbiosis, this is also the inherent requirement of building a conservation-oriented, ecological, livable and harmonious city.
Third, building a city of solar energy is a project to benefit the people. Building a solar city, promoting and using solar energy products in the whole society can directly reduce energy consumption, save expenses, reduce pollution, and beautify homes. Every unit, enterprise, family and individual are beneficiaries. Not only economically, but also greatly improving the living environment. According to experts' tests, the use of one square meter of solar water heaters is equivalent to saving 180 kilograms of standard coal per year. The annual use of solar cells is 10 megawatts, which is equivalent to reducing carbon dioxide emissions by 10,000 tons per year, which can effectively reduce coal, straw and firewood. The dust caused by the burning, and the blue sky above our heads. Especially for an old industrial base like the city, for a city with a strong environmental protection pressure in the city, the promotion and use of solar energy products in the city will undoubtedly play a role in saving resources and protecting the environment. . In this sense, building a city of solar energy is an environmental revolution and a moral act for the benefit of the people.
Fourth, building a solar city is a need to enhance the image of the city. The city's distinctive image is the best business card in the city and a valuable resource and wealth. For example, Kunming is the spring city, Hangzhou is the leisure capital, Dalian is the romantic capital, Qingdao is sailing the sea, and so on. Every special city card is a microcosm of urban culture and an important image productivity. We Baoding proposed to build a garden-style, ecological, modern and livable city with unique cultural characteristics in northern China. The current municipal government's key plan is to work hard on “waterâ€, “ancient†and “brightâ€. "Water" is to start the construction of urban water system, and strive to achieve urban river clearing and bring aura to the city. "Ancient" is to restore the historical features of the West Street and other neighborhoods, to do a good job in repairing cultural relics such as the Guangyuan and Huaijun Military Offices, and strive to make the old city reproduce the "history rhyme" of the ancient city. “Bright†is to speed up the construction of the city of solar energy and dress up the night of Baoding more beautifully. We must not only let the sun illuminate the daytime of Baoding, but also store it and illuminate the night of Baoding. It can be said that the construction of solar energy city is not only an important part of urban construction, but also an important content of urban cultural image shaping. It is a new business card for building Baoding city image, which is of direct significance for the overall improvement of Baoding image.
At present, there are still some comrades on the issue of building a solar city. There are three main aspects. The first is the cost issue. Some people think that the one-time investment in solar energy products is too high, and the economic pressure is great. Compared with traditional coal, oil, electricity, gas and other energy sources, solar energy products have a higher cost of one-time investment, but it is very economical and cost-effective to calculate from a certain time span. I have an example here: a 5 km long section, symmetrical installation of street lamps on both sides, using 10 m cone rods, double lamp heads. In the case of ensuring that the road illumination is basically the same, the cost is calculated by using 66W solar LED street lamps and 400W high pressure sodium lamps, respectively. The installation cost of solar lamps is 6.5 million, the average lamp is 3.8 million; the life of solar lamps is 10 years, and the average lamp is only 1 year; if it is calculated for 8 years, the total cost of solar lamps is 688.78 million, while ordinary lamps plus The cost of power-on and lamp replacement is 8.744 million yuan. It does not include the annual maintenance and maintenance of traditional street lamps, the investment in control equipment and facilities, and the salary and office expenses of employees. In this way, the use of solar lights saves more than 1.8 million yuan and saves 25% compared to the use of traditional street lamps. From this it can be inferred that after 4.78 years of use of solar lights, the overall cost is the same as the overall cost of traditional street lamps for 8 years. In other words, in the next three years, solar lights will save 600,000 yuan per year. If coupled with the factors of high efficiency, energy saving, environmental protection and rapid technological advancement of solar lamps, this account will show the advantages of solar lamps. Look at the water heater: According to estimates, each square meter of solar collectors can output an average of 400,000 kilocalories per year, equivalent to 517 degrees of electrical energy. If a household installs 2 太阳能 of solar collectors, it can save 1034 degrees per year and save about 537 yuan in electricity costs. According to the current purchase of a solar water heating system, the price of 1,600 yuan is equivalent to only 3 years of electricity, while the solar water heating system generally has a service life of more than 15 years. Nowadays, rural households in Spain and Germany use solar cells and water heaters in almost every household. In Japan, the unique advantage of using solar power in the home is that electricity is not used during the day, but electricity is sold to the power company or the government, and the latter is actively acquired, so that the income can be used to offset part of the electricity bill. There is also the “Electric Valley Building†under construction in the high-tech zone of our city. The facade of the Chaoyang building is all solar panels. After it is completed, it will become a small power station, and the electricity generated can directly enter the urban power grid. With solar energy, the initial investment may be a little bigger, but after a few years, it is equivalent to saving money and making money. The second is technical issues. Dongfeng Bridge of our city is the first pilot section to install solar street lamps. It has caused widespread concern of the media and the general public. The Yanzhao Metropolis Daily also made relevant reports. However, during the use, some people reflected that the solar street lights were “not bright enoughâ€. This is mainly a technical issue. First, there is a gap between the current level of LED lighting and ordinary lighting. In our country, there is no uniform standard for the parameters of LED lighting products, so we can't simply measure whether it is bright or not. In addition, the market is not standardized, and the quality of the products is uneven. Therefore, during the promotion and use. There is a problem of irregularity. Second, the solar streetlights we currently use have already met the national lighting requirements for urban roads. The brightness of traditional lighting used in the past has generally exceeded the brightness standards set by the state, so it is now felt that the solar street lights are not bright enough. The brightness problem of LED lighting is the key technology that is being researched and tackled by countries all over the world, and is constantly improving in application. According to experts' prediction, by 2010, China's LED lighting technology level will far exceed the fluorescent lamps and energy-saving lamps we use now, becoming the most economical, convenient and practical solid-state lighting technology. It can be said that any problem that hinders the use and promotion of solar technology is not a problem and can be solved in the near future. The third is the concept of ideas and understanding. This is the question of how to understand this new thing in solar energy application. This is the core and most critical issue. On this issue, we must not only count the economic accounts, but also the accounts of quality of life, the accounts of environmental protection, and the accounts of energy conservation. It is a long-term account rather than an account, and it is a big account rather than a small account. We must not look at the input in front of us. We must pay attention to the establishment of the city image, the improvement of the living environment, the enhancement of environmental awareness, and the cultivation of awareness of conservation. We are promoting this work by promoting civilization, which is to cultivate the next generation's awareness of saving resources and protecting the environment. To build a city of solar energy, it is also necessary to establish a kind of orientation, that is, to take the lead in promoting the development and utilization of new energy products, and strive to build an energy-saving and environment-friendly city to realize the harmonious development between man and nature.
Building a city of solar energy, the city has a good foundation, especially the industry base. At present, the "China Power Valley" construction momentum is very good, signed a strategic cooperation agreement with North China Electric Power University, and the provincial bank has initially reached 6 billion yuan. A loan-backed agreement, a large batch of projects such as Tianwei Yingli 500 MW solar cells with an investment of 3 billion yuan, was successfully promoted. AVIC Huiteng signed a production contract of 3.7 billion yuan this year and next year. The country's largest wind power producer, Guodian Group, etc. Well-known companies have rushed to Baoding, and Tianwei Yingli has also reached the world's largest 62 MW solar power plant agreement with Portugal, the world's largest solar energy company, and so on. The development prospects are very broad. Since last year, the city's LED lighting companies have grown from scratch to more than 10, and have a good start in the field of solar lighting industry. The construction of solar energy city in our city is also a major measure to build "China Power Valley". It and the "China Power Valley" rely on each other and promote each other. One is industrial support, and the other is application of results. The purpose is to achieve mutual leverage. And benign interaction. In addition, the city has excellent climatic conditions and good sunshine conditions, and the annual solar energy utilization rate can reach 80%. We should have the confidence and determination to do a good job in this pioneering work that is related to the progress of social civilization.
