At the national energy conference that was reopened 17 years later, the country proposed to vigorously develop new energy resources in the future. However, the current situation of new energy development is not optimistic. What kind of problems are there in the promotion of new energy? Check the reporter's investigation.
This is the westernmost tip of Hexi Corridor in Gansu Province, Yumen Pass in Gansu, and it is also one of the regions with the most abundant wind resources in China. Through the lens, we can clearly see that the huge wind power generating units in the thousands of miles of the Gobi are everywhere, according to the design and planning, the wind here. Once the generator set is in normal operation, it can effectively ease the power shortage in North China and East China. However, it is regrettable that these Gobi windmills, which were built with huge investments, can now only stand quietly in the desert.
Director of Northwest Power Grid Technology Center Yi Lidong
The network is too weak to withstand the impact
Lidong Li told reporters that due to the influence of wind power on the wind power generation, the amount of power generation is not stable, and the capacity of the northwest power grid is relatively small. Therefore, there is a mismatch between wind power and the power grid. Until now, wind power in Xinjiang has still not been connected. Into the national grid system, a huge investment in the construction of the Gobi windmill, can only be in a stagnant state.
Not only is wind energy experiencing development difficulties, but another major factor in new energy is the development of the solar energy industry in China. Dezhou City, Shandong Province, is a major production base for solar energy products in China. The reporter noticed such a detail. Many residential buildings, especially new ones, have installed solar water heaters. Not only that, but also the stores that sell solar energy products are here. Everywhere. However, when interviewed by reporters, many solar energy production companies told reporters that the days are not too good.

Lack of strict standards, encountered resistance in the promotion of rural cities.
Another important factor hindering the development of the solar energy industry is the lack of independent intellectual property rights. Many companies have equipment, raw materials, and markets that are highly dependent on foreign countries. They have no say in core technologies and value-added links. This way, the price of products cannot be controlled. It looks like a bustling, high-tech aura, actually only At the low end of the entire industry chain, one of the important reasons for this status is that the government’s corresponding subsidies and financial support for the development of the solar energy industry are still far from adequate.
New Energy Popularization Urgently Needs Policy Coordination
In the face of real problems, how should China's new energy development path go in the future? Listen to what the experts say.
Many new energy experts said in an interview with reporters that the top priority for new energy development is to establish a complete set of new energy technology roadmaps as soon as possible.
Academician of the Chinese Academy of Engineering Gu Guojun
Because a new production is subject to the perfection of process production, and then to the test of application, it is hoped that the production side will have a good consideration, including the R&D unit to further improve the production technology.
Take wind power as an example. At present, in many places in China, wind farms are often local or corporate. They lack the considerations of national overall planning. This is why the power plant cannot be accessed after it is built. Therefore, for wind power, the first thing to do is to solve the problem of matching wind power and power grids as quickly as possible. On the one hand, the capacity of the power grid must be taken into account when constructing, and on the other hand, the reform of the power grid should be strengthened as soon as possible. Try to make wind power available online sooner. In addition, experts also suggested that the state should introduce corresponding support policies as soon as possible to ensure the rapid promotion of new energy sources.

For a new thing, its development still needs policy support. If it does not have the support of the policy, it will simply get the market to compete. It is incomparable with a conventional power plant, and policy support is still more crucial.
China’s new energy vehicles have a maximum subsidy of 600,000 yuan per vehicle
As everyone is looking forward to the development of new energy sources, the reporter learned from the Ministry of Finance and the Ministry of Science and Technology today that the interim measures to encourage the use of new energy sources in the automotive industry have been introduced. Let's find out together.
The financially supported energy-saving and new energy vehicles mainly refer to hybrid vehicles, pure electric vehicles, and fuel cell vehicles. The subsidy standards are mainly based on the basic difference between energy-saving and new energy vehicles and similar conventional automobiles, and are appropriately determined by factors such as scale effect and technological progress. Specifically, among passenger cars and light commercial vehicles, hybrid vehicles are divided into five categories of subsidy standards according to the fuel-saving rate, the maximum subsidy for each car is 50,000 yuan, and pure electric vehicles can be subsidized by 60,000 yuan each; fuel cell vehicles Each subsidy is 250,000 yuan.
There are separate standards for bus buses of more than ten meters in length, of which hybrid vehicles are classified into lead-acid batteries and nickel-metal hydride batteries and lithium-ion batteries. The maximum subsidies are 80,000 yuan per vehicle and 420,000 yuan per vehicle. The subsidy standard for electric vehicles is 500,000 yuan per vehicle; the subsidy standard for fuel cell vehicles is 600,000 yuan per vehicle. New Energy Bus Promotes Commercialization of New Energy Vehicles in China
From the previous measures, we can see that the state’s largest subsidy for new energy vehicles is the new energy city bus. So why should China start with public welfare city buses? Let's listen to experts' arguments again.
China Machinery Industry Federation executive vice president Zhang Xiaoyu
Foreign practices directly subsidize the money to consumers, such as Japanese hybrid cars. I buy one for each. The government gives you a subsidy of 50,000 yen. Our new energy vehicles, energy-saving and new energy vehicles are in an initial stage / but this Why things can not be commercialized and modeled, is the cost is still high.
Zhang Xiaolu said that from the calculation of domestic new energy vehicle costs, such as the increase in the cost of hybrid vehicles at 30% to 50%, according to different configurations of traditional bus passengers, each priced at between 300,000 to 800,000 yuan, hybrid buses The price is 100-150 million. Therefore, subsidizing the public service industry such as public transportation companies is a benefit for the entire people. Reducing emissions will bring about social benefits. However, Zhang Xiaoxuan also pointed out that the current commercialization of new energy vehicles, basic research is still lacking.
China Machinery Industry Federation executive vice president Zhang Xiaoyu
The most scarce ones are basic research, such as battery research, motor research, and research on the entire control system./(0535) Countries must provide necessary funding and funding support.
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications.
