"Eleventh Five-Year Plan" Renewable Energy Development Target is Expected to Be Realized Next Year
Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.
Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.
Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The packaging must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.

Li Junfeng said that of the 10% of renewable energy, mainly hydropower, wind power, and solar energy are all included. The main one is hydropower, and hydropower will account for more than 8 percent.
Li Junfeng reminded that China has installed 150 million square meters of solar water heaters, which is equivalent to reducing the consumption of several million tons of standard coal, but this has not received enough attention. In addition, nearly 30 million households in China use biogas. This figure is also quite large.
In September of this year, President Hu Jintao proposed at the UN Climate Change Summit that China will vigorously develop renewable energy and nuclear energy, and strive to achieve a 15% share of non-fossil energy in primary energy consumption by 2020. Li Junfeng pointed out that the goal set by Europe in the same period was 20%. It is much harder for China to achieve the 15% target than the 20% target for Europe, because China has set this goal on the premise of continuous growth in total energy consumption, while Europe’s energy consumption has been declining.
The 2009 China Clean Energy International Summit was sponsored by the China International Chamber of Commerce and the British "Financial Times" and was held in Beijing from November 2nd to 3rd. The theme of this summit is "Clean Energy - The Future of Mankind, Shared Responsibility". It aims to promote international exchanges and cooperation in the field of clean energy and promote China's transition to a green economy.
