Recently, the national large-scale continuous haze people worried. A time when the two sessions held, the haze "lucky" topped the two representatives of the most top topic of concern. Haze governance imperative.
Wuhan Research Institute of Posts and Telecommunications, deputy chief engineer of Cheung Kong Scholars, Huazhong University of Science and Technology Liu concerned about the haze has been a long time. Governance haze is much more than just control the impurity content in gasoline is so simple. "Liu said, control petrol impurities can only play" Yang boiling soup "effect, in order to" backing off "on the need to vigorously develop new energy economy In particular, the solar economy.
"Governance haze must control the proportion of thermal power, substantial adjustments in the structure of energy production, focus on the development of a new solar-based energy economy." Liu told reporters, in fact, from 1990 to 2011, China's installed power generating capacity has grown from 150 million kilowatts to 1.06 billion kilowatts of thermal power installed capacity accounted for 70%, but power generation accounts for 80%. "This could be a main reason nationwide haze increasingly serious."
Liu said, the development of electric vehicles is one of the measures of governance haze. However, electric vehicles and high-speed rail, urban rail only "burn" solar cell and other clean energy generated power have environmental significance, if you still rely on thermal power, may not as directly burning gasoline.
Faced with questions from reporters, Liu analysis, in addition to the limited resources of hydro, the current development of China's new energy ideas mainly wind energy, nuclear energy, solar energy. He said, China's installed capacity of wind power has been ranked first in the world, but because the grid and wind turbine performance and reliability factors, still have not received the desired effect, need to make great efforts to rectify. Nuclear energy density, the use of high efficiency, energy output power stability, but risky, especially after the Fukushima nuclear power plant accident in Japan, many of the world's nuclear power developed countries, more and more attention to the development of alternative energy, especially solar energy industry.
The data show that the sun Earth Hour energy sufficient to all mankind year energy consumption, can be said to be inexhaustible. There is no doubt that the development of solar and other new energy economy has become the best choice of the present and future.
"Investment in solar and other new energy economy is to invest in a beautiful ecological building beautiful China must rely on the development of a new energy economy." In Liu's view, Tibet, Qinghai, Xinjiang, northern Sichuan, Inner Mongolia, Ningxia, Gansu and other regions, sparsely populated , very rich in solar panel energy resources, occupied 01,000 square km of land resettlement 100GW of solar power generation equipment, peak power equivalent to five Three Gorges Power Station.
China's vast territory, the development of solar energy resources owned by different regions of Qinghai, Gansu, Xinjiang has a large number of high irradiance conditions; Mainland has the photovoltaic industry R & D and the foothills of the construction of water storage power station advantages; East China and China Southern Power Grid has formed over long distances The high-voltage transmission grid operator experience. "If harmonization, give full play to the advantages of high-tech talent and vast geographical advantages, China conditionally accelerated development on the road to the development of solar technology and applications."
Talking about how the development of solar energy in the technological innovation efforts, Liu said, condenser and multi-junction cells, the third generation of solar photovoltaic technology has the photoelectric conversion efficiency is raised to 44%, and the production process has little pollution, energy consumption the advantages of low cost, it is recommended that the relevant departments attach great attention to this important development direction.
High-power condenser, multi-junction photovoltaic material production efficiency is high, can be less than the cost of nuclear and thermal power generation cost of power generation of high-power condenser enters the large-scale application.Concentrating photovoltaic technology commonly used high bracket and automatic tracking technology, not only does not affect the installation of ground vegetation growth to absorb most of the sun in the summer, making the installation area originally barren because of drought and water shortage, gradually become a prairie oasis, is conducive to the improvement of the local ecological environment.
