Oil is the blood of survival in modern society. Since 1996, China has changed from an oil exporting country to an importing country. In 2004, China's oil demand was around 300 million tons, but its production capacity was only 100-700 million tons. In 2005, China's oil demand reached about 300 million tons, surpassing Japan and becoming the world's second largest oil consumer after the United States. However, China's oil production has not increased significantly. From net imports of 40 million tons in 1999 to more than 100 million tons now, China's dependence on oil reached 47.3% in the first half of this year. In 2010, China's oil demand may reach 300-800 million tons, and in 2020 it will reach 500 million tons. By then, oil imports will reach 300 million tons, and imports will exceed half of domestic demand. With the rapid increase in China’s oil imports, how to ensure that the entire * * energy security? Suggestions are flying around to speed up the exploration and development of domestic oil and gas resources, carry out oil diplomacy, and develop overseas oil fields... But now the call for developing alternative fuels and alternative technologies is rising again. From a global perspective, fossil energy is facing depletion. As the world’s largest developing * * my country's energy situation is even less optimistic. The imminent depletion of fossil energy and severe pollution will soon or have already become a nightmare for mankind. Especially in our country, it has restricted our country's economic and social development, led to the deterioration of people's health, and caused our country to pay a huge political cost for this.: The competition with Japan for Russia’s Antai Line, the failure of CNOOC’s acquisition of Unocal, the security of the Malacca Strait, etc. All these show that China's energy is still insecure and has become a bottleneck for China's development. If this situation is not effectively contained, it will become a nightmare that worsens China's development environment. In addition to tight energy supply, another problem is the serious environmental pollution caused by massive domestic carbon dioxide emissions. According to relevant data, my country's energy structure is characterized by being rich in coal, poor in oil, and low in gas. Energy consumption is mainly dependent on coal. my country is rich in coal resources. Domestic mining has reached 2.1 billion tons. With increased technology, large quantities of coal can be mined. This coal-dominated energy structure is the main cause of serious environmental pollution. “Although international regulations have been issued to limit carbon dioxide emissions. However, this provision currently only applies to developed countries * * , and our country is currently not a developed country * * , there is no obligation to limit carbon dioxide emissions, but according to my country's economic development trend, our country will be included in the scope of limiting carbon dioxide emissions in a few years. At present, my country's carbon dioxide emissions rank second in the world, second only to the United States and higher than Japan and Europe. * * . Suppose my country's carbon dioxide emissions are limited, and domestic coal mines account for about 70% of the country's total, oil accounts for about 20%, and accounts for about 90% of the country's total energy. Due to heavy use, mining and utilization cannot be stopped immediately, and corresponding emission fees must be paid in accordance with international law. The unit price of the emission fee is US$15 per liter of carbon dioxide, which is another burden on the Chinese economy. ”Wu Chuangzhi analyzed. China's economy is developing rapidly, and some experts predict that: Energy supply will double in 15 years, and there will be a contradiction between tight energy supply and air pollution. Renewable energy has attracted the world's attention with its unique charm. Renewable energy, with its infinite cycle, can fundamentally meet the endless needs of mankind. At the same time, renewable energy is also a green and environmentally friendly energy, which is crucial to improving people's quality of life. many * * Especially developed * * They have invested heavily in the research and development of renewable energy and have achieved amazing results in a short period of time. China did not stop and accelerated its pace of catching up. In the 1980s, it formulated a 16-character policy for the development of renewable energy.: “"According to local conditions, complementing multiple energy sources, comprehensive utilization, and focusing on efficiency", positioning renewable energy as an auxiliary and supplementary energy source. Renewable energy sources include wind energy, solar energy, hydrogen energy, ocean energy, biomass energy, etc. Biomass energy is diversified and widely used around the world. Only biomass energy resources can be converted into liquid fuel and are the only renewable energy sources that can be transported and stored. In 2004, the production of ethanol, biodiesel and other biofuels exceeded 33 billion liters, and 3% of the world's 1.2 trillion liters of gasoline was replaced by ethanol. Biomass energy is inexhaustible. According to statistics, global biomass resources are as high as 10 billion tons of dry matter. The biological output of forests, grasslands, and cultivated land alone is 5 billion tons of dry matter, equivalent to 2 billion tons of standard coal. Currently, the annual global biomass production is approximately 6 to 10 times the global total energy consumption. Analysis by China’s Ministry of Commerce shows: At present, the mainland's artificial forest area reaches more than 53 million hectares, with a timber storage volume of 1.505 billion cubic meters. ； In particular, there are more than 54 million hectares of barren hills and wasteland suitable for forestation in mainland China that are not suitable for farming. 20% of the land is used to plant high-yielding energy plants. Based on the annual growth rate of 20 tons per hectare, the annual biomass produced can reach 200 million tons, which is equivalent to more than 100 million tons of standard coal. At present, the main raw materials that can be used for bioenergy processing in mainland China include sweet sorghum, cassava, sugar cane, Jatropha curcas, etc. our country is in * * Under the guidance of policies, the research and development and production of biomass energy are at the forefront of the world. At present, my country has made important progress in internationally recognized key technologies such as lignocellulose hydrolysis and metabolite separation and purification. “"Biodiesel" technology has made new breakthroughs. In five years, it is expected to reach the production capacity of Daqing Oilfield and become a "green oilfield" with an annual output of 50 million tons. Perhaps many people now know that ethanol can replace gasoline as a vehicle fuel. In fact, there are already more than 5 million cars in the world using ethanol fuel. These ethanol-fueled cars are not only more economical than cars using gasoline as fuel, but also emit almost no harmful greenhouse gases to the environment. With international crude oil prices skyrocketing and the hydrogen economy in sight, economists predict that only ethanol will replace gasoline as the green fuel that humans rely on for survival in the future. Biodiesel is a clean, renewable energy source. It is a liquid fuel made from oil crops such as soybeans and rapeseed, oil forest fruits such as oil palm and Pistacia chinensis, oil aquatic plants such as engineered microalgae, animal fats, and waste cooking oil. It is a high-quality petroleum diesel substitute. Biodiesel is a typical "green energy". Vigorous development of biodiesel has important strategic significance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution. As we all know, diesel molecules are composed of about 15 carbon chains. Studies have found that vegetable oil molecules are generally composed of 14-18 carbon chains, which is similar to the number of carbon atoms in diesel molecules. Therefore, biodiesel is a new type of fuel produced by processing renewable vegetable oils such as rapeseed. According to chemical composition analysis, biodiesel fuel is a high-fat acid methane, which is obtained through the decomposition of glycerol with unsaturated oleic acid C18 as the main component. Yangxin County Party Committee and County, Shandong Province * * In order to get rid of the backward situation, based on the national conditions and county conditions, we actively and vigorously develop the sweet sorghum planting industry, which not only creates a happy road for farmers to achieve a well-off life, but also provides a strong guarantee for the development of new energy. Two biomass energy projects invested by China National Cereals, Oils and Foods (Group) Co., Ltd., BP Group and Vitol Group, a large international oil sales company, three of the world's top 500 companies, have recently settled in Yangxin County, Binzhou City, Shandong Province. This means that the construction of the country's first biomass energy demonstration county has been put on the agenda. These two projects include the sweet sorghum straw-to-fuel ethanol project jointly implemented by COFCO and BP Group, and the biodiesel project invested and constructed by Vitol Oil. Industry experts said that related projects backed by three Fortune 500 companies can strongly drive the scale and intensification of sweet sorghum planting in Yangxin and even the Yellow River Delta region, opening up huge space for Yangxin to gather industrial clusters around biomass energy and lengthen the industrial chain. We have reason to believe that biomass energy can not only bring blue skies and clear water to China, reduce energy shortages, provide a strong driving force for China's development, but also provide a shortcut for farmers to become rich. We also have reason to believe in our economic scale, our technological strength, our * * Cohesion is not what it used to be. In the face of such opportunities, as long as we increase investment and devote ourselves to development, China will be the leader in renewable energy.
