May 28, Department of Commerce in Nanjing International Symposium on low-carbon industries. Many domestic and foreign experts, entrepreneurs in the spotlight on wind power, photovoltaic solar energy, geothermal energy, LED lighting and other "green energy" at the same time, calls for low-carbon industries to orderly development, beware of blindly throw excessive investment, excess capacity.
Global invest five $ 100 billion per year
The international financial crisis broke out, so that the "low carbon" overnight hot all over the world. Vice Minister Jiangyaoping pointed out that entry after the financial crisis, the times, because Europe and the United States and other developed countries are looking for stimulating the economy of new growth points, and put the focus on the low-carbon economy, low-carbon technologies.
Experts, global 3 trillion economic stimulus funds, more than one third of the vote in the green technology field. Some developed countries have a low-carbon industries and products as the main export directions. For example, Denmark, 1992 to 2005, exports of energy technology product and services revenue by 50 billion Denmark kroner increased to nearly $ 40 billion kroner, 13 8 times a year.
The same low-carbon industries in China in the ascendant. Chinese renewable energy professional Committee Executive Director, Ma-ling-Juan said, "our country has published more than 30 supporting policies to encourage the development of low-carbon industries. Wind power installed size for the fourth consecutive year, double the growth rate of solar water heaters more than 30%. "2020, China's clean energy to account for 15% of total energy, the layout is about 6000 million kilowatts of nuclear power, 1.2 — 1.5 billion kilowatts of wind power, 30 million — 5000 million kilowatts of solar power. If you plan to fruition, will reduce the 10 billion tonnes.
According to the forecast of World Economic Forum 2009, the next 40 years, the global investment in low carbon industry each year in more than five billion, the prospects are very broad. "Low-carbon will become China's economic development, new impetus and fuze, will also be leading the industry in system, consumption patterns of reconstruction of the new wind vane. "Chinese architectural glass and industrial glass Association Vice President Zhang Jing Tao said.
The practice of "low carbon" not sticking
The "low carbon" warming, path.
Ma-ling chuan, wind power, photovoltaic, biomass, etc. in the rapid development within the context of globalization. These years, the average annual growth rate of wind power generation in China are about 30%.
No air conditioning, no boiler, continue on foot to make the urban architecture of geothermal energy in winter heating, us science and technology General Manager shengheng highlights of this new type of heating. The "shallow ground can exist in a constant temperature underground within several hundred meters of soil, sand and ground water, the enormous widely distributed, energy, and fast regeneration. Use ground-source heat pump technology exploitation to be shallow, energy saving and environmental protection effect is very significant. ”
Experts, will resources in shallow ground, nearly a hundred meters of soil each year acquisition of low-energy 1.5 trillion kW, 100 m in annual acquisition of groundwater low energy or up to 2 million kilowatts. While each of the 10 million square meters of ground source heat applications save 56 000 tonnes, 205 million tons of carbon dioxide emissions.
Solar power not only to the heating, refrigeration. A new stadium in Rushan, Shandong in the installation of this warm in winter and summer clothes of solar air conditioning. "The solar system and building integration concepts for solar energy utilization has opened up space, making use of relevant technology, solar energy can achieve full-year supply of hot water, winter heating and summer air conditioning for medicine. "Professor Zhiqiang, Tsinghua University, said that by 2050, China's only in low temperature solar thermal utilization of a can of emission 5.4 billion tons of carbon dioxide.
Energy is the energy-saving emission reduction of focus areas, modern city "glass box"-nice but not saving.
