According to the latest data from the National Bureau of Statistics, China's crude oil imports in April reached a year-on-year growth rate of 14.7%, with an average daily import of 1.315 million tons, a record high, and natural gas imports maintained a high growth rate of more than 30% for seven consecutive months.

The Chinese economy has entered a period of transition, but the international energy market has entered a rising cycle, which is very stressful for China's energy supply. Russia, the United States and other big countries are rich in oil and natural resources, and renewable energy development is also very effective, so energy can be independent and can be exported; Denmark, Norway and other Western European developed countries, although the local coal oil and natural gas is less, but based on the local development of renewable green energy The proportion of energy in the country is getting higher and higher, and it is gradually embarking on the road of energy independence.

How China combines its own resource characteristics and development characteristics, and seeks truth from facts to embark on a road of energy independence and green sustainable development. It is a strategic issue that all energy workers and energy companies seriously consider.

The first point is building energy efficiency and reducing energy consumption. One of the reasons for the huge total energy consumption in China is that buildings are not energy-efficient, building walls and doors and windows are of average quality, and the heat insulation effect is poor. The winter is very cold and the summer heat needs to consume a lot of heat and electricity generated by fossil energy to meet winter heating and summer cooling. In order to make people more comfortable for the summer and winter.

Passive buildings can solve this huge energy consumption well, that is, use good windows and doors with high cost but good quality and good sealing. When the wall is insulated and equipped with a fresh air system, it can be done without heating in winter. In summer, there is no need to open air conditioners, constant temperature and humidity and constant oxygen, which not only can greatly reduce energy consumption, but also enable people to live a more comfortable and beautiful life.

If passive buildings are fully promoted in municipalities with rich financial resources, provincial capitals, cities with separate plans, and other cities with financial resources and willingness, new buildings cannot meet the requirements of building energy conservation, and old buildings that can carry out energy-saving renovation, especially rural buildings, Government subsidies and encourage energy-saving renovations are far less than the annual subsidies for subsiding coal to electricity and coal to gas.

The second point is that energy conservation is one of the most important measures for China's energy independence. The Chinese economy is undergoing a transition from high-speed development to high-quality development. The protection of large rivers and clean urban environmental protection activities has been widely spread. The heavy chemical industry structure system that consumes a large amount of coal and oil will be rapidly adjusted. The total energy consumption of energy-consuming households such as coal de-capacity, steel de-consumption, and low-value-added petrochemical (chemical) de-capacity will also decline. It can greatly reduce the dependence of China's oil imports on foreign countries.

At the same time, the city strictly controls the development of fuel vehicles, increases the cost of parking fees, congestion fees, etc., and advocates green modes such as subways, city rails, high-speed rails, buses, and shared bicycles, and vigorously develops electric vehicles to replace buses and taxis. These vehicles, such as garbage trucks, can also significantly reduce the consumption of oil.

The third point is to fully develop green energy with other power flexibility, which can fully meet the needs of people. China lacks oil and gas, but it does not lack the resources for renewable energy development such as wind, sunlight, water, geothermal, biomass and garbage. In particular, all kinds of distributed energy sources, such as distributed wind power, distributed photovoltaics, and distributed gas energy stations, which are closer to users and more easily meet user needs, work closely with the microgrid and can complement each other, which can greatly reduce the concentration on large scale. Energy and the dependence of large power grids.

Offshore wind power and geothermal, which have great potential for renewable energy, have just been put into development. Large enterprises that need financial strength, especially energy central enterprises, have invested in renewable energy and led the rapid development of China's domestic renewable energy.

If it can cancel the main business restrictions of energy central enterprises, especially coal companies and oil companies, encourage more capital investment in the field of renewable energy with strong correlations - for example, the oil and gas wells on land in China will be used for shallow geothermal resources. Re-development, the exploration of geothermal resources using old oil wells, can be considered very cost-effective and valuable; can also transform the concept, increase the exploration and development of geothermal fields, geothermal heat can meet the energy demand system without burning Zhongfeng Valley has a huge difference in clean heating demand.

The wind power on the sea is large, it does not need to occupy the cultivated land, and it is close to the power load center of the eastern coastal city. The offshore oil and gas field and the offshore wind farm are integrated and developed. The comprehensive construction capability of the marine engineering can be fully utilized, the human and material resources can be fully utilized, and the economic benefits can be greatly improved. improve.

Biomass, garbage, etc. have not been used to the fullest, but have become a source of pollution in the field burning and garbage. If we actively encourage various capital investments to build biomass thermoelectricity and waste-to-energy, we will accumulate the natural growth of plants and people in China. When the garbage is used, it can produce more green energy such as heat and electricity, and meet the demand for energy.

Solar photovoltaics and light and heat are inexhaustible. At present, the rapid development of distributed photovoltaics is to turn the roof of every household into an energy production site, which can meet the energy demand of people and reduce the energy consumption of conventional electricity.

Fossil energy, based on the local. China's coal resources are abundant. It is the main energy source in China. Under the premise of keeping up with all aspects of green energy, if it is forbidden to import coal with serious pollution, China's domestically increased coal production can also meet the demand. China should also introduce policies to encourage various capitals to explore and develop oil and natural gas in China, because the strategic value of local oil and gas fields is higher than that of overseas oil and gas fields, which not only can generate profits, but also ensure China's energy security. It should even allow for greater risk to invest in the exploration of oil and gas resources, especially in the difficult exploration of the South China Sea and the desert.

In view of the fact that China's energy system and industrial system have established an economic system with oil as an important pillar, de-petroleumization is a relatively long process, but burning more gas is more clean than burning more than one liter of oil. Therefore, moderately increase natural gas outside the country. Or the import of LNG is better than imported oil, and the replacement of refined oil by LNG for long-distance buses, heavy trucks and inland vessels is more conducive to reducing pollution from mobile sources.

To sum up, as long as China's energy conservation and consumption reduction and vigorous development of local renewable energy are done well, it can greatly reduce the dependence of oil on foreign countries. The reduction of coal can match the increase of renewable energy, and it can also reduce oil and gas imports. Vigorously investing in the development of local oil and gas resources will directly reduce imports. As long as we conscientiously implement the spirit of the 19th National Congress, change the concept of energy investment development, and promote China's energy as soon as possible, and embark on the road of green renewable energy development is fully achievable.
