While traditional energy such as coal is still the main energy source at present, the author believes that in addition to considering renewable energy sources, energy conservation and emission reduction should be more based on national conditions and tap potential from traditional energy sources.
First, the power of renewable energy is "limited." In recent years, the development of renewable energy in China can be described as rapid progress. In 2010, the cumulative installed capacity of wind power in the country exceeded 44.7 million megawatts, the installed capacity of solar energy reached a total of 800,000 kilowatts, and the installed capacity of hydropower exceeded 200 million kilowatts. All data are among the highest in the world, and they are well-known as large renewable energy sources. Even so, in the energy structure of our country, the proportion of non-fossil energy is still less than 8%. Even if we achieve the target of 15% by 2020, the proportion of fossil fuels is still relatively small.
Experts predict that China’s energy-based energy structure will not fundamentally change for a long period of time. From this point of view, in the near future, energy-saving and emission-reduction will not be enough for the development and application of renewable energy.
Second, there is huge space for the clean and efficient use of traditional energy sources. In recent years, the energy consumption per unit of output value of our country has continuously declined. In 2010, it was 19.6% lower than in 2005. However, the energy consumption per unit of production is still high, which is three times that of the United States, four times that of the European Union, and five times that of Japan. Data shows that the gap between China's energy efficiency and developed countries is still very large. It also shows that energy-saving and emission-reducing, and relying on the efficient use of traditional energy sources have great potential to be tapped.
Again, related technologies have been initially available. As a coal-utilizing country, we have made great strides in coal processing, coal chemical and supercritical technologies, carbon dioxide capture, and storage technologies. At present, the most important issues to be solved are the unified guidance of macroeconomic policies, coordination among industries, and the promotion of new technologies in an all-round way. When these tasks are done, they will have lower costs, newer energy costs, and more significant results.
In summary, as the main energy source of coal in China, it is not only the factor that causes the pressure of energy saving and emission reduction, but also the main direction of energy conservation and emission reduction. Therefore, during the "12th Five-Year Plan" period, we must achieve a 16% and 17% target reduction in energy consumption and carbon dioxide emissions per unit of GDP. We should also use traditional energy as the "main battlefield."
Welded Wire Mesh Concrete Panel
Welded WIRE MESH Concrete Panel: A welded wire mesh concrete panel, also known as a concrete reinforcement panel, is a prefabricated panel made by welding steel wires together at their intersections. These panels are used to reinforce concrete structures, such as walls, slabs, and columns. The welded wire mesh provides strength and stability to the concrete, helping to prevent cracking and enhance structural integrity. These panels are commonly used in construction projects to improve the durability and load-bearing capacity of concrete elements.
Galvanized Brick Wire Mesh for Building: Galvanized brick wire mesh, also referred to as brickwork reinforcement mesh, is a type of wire mesh that is specifically designed for masonry applications. It is made from galvanized steel wires formed into a grid pattern. The mesh is typically embedded within mortar joints between layers of bricks or blocks to provide additional tensile strength, prevent cracking, and improve the overall stability of the masonry structure. The galvanized coating on the wire mesh provides corrosion resistance, ensuring long-lasting performance.
Welded Wire Mesh Panels for Construction: Welded wire mesh panels are prefabricated panels made by welding steel wires together at their intersections. These panels are commonly used in construction for various applications, including security fencing, partitions, enclosures, and reinforcement of concrete structures. Welded wire mesh panels offer versatility, strength, and ease of installation, making them suitable for a wide range of construction projects.
Reinforcement Wire Mesh Panel: Reinforcement wire mesh panels are specifically designed to provide reinforcement to concrete structures. These panels are typically made from steel wires that are welded or woven into a grid pattern. Reinforcement wire mesh panels are placed within the concrete slab or wall to enhance its tensile strength, control cracking, and distribute loads more effectively. They are widely used in construction projects such as flooring, walls, foundations, and precast elements to improve structural performance and durability.
These different types of wire mesh panels, including welded wire mesh concrete panels, galvanized brick wire mesh for building, welded wire mesh panels for construction, and reinforcement wire mesh panels, offer solutions for reinforcing and enhancing the strength of concrete structures. The choice of the specific mesh panel depends on the intended application, the level of reinforcement required, and the project's specifications.
