Solar power can complement gap?

Solar power can fill gaps in 2010 once the total energy consumption in China is 32. 500 million tons of standard coal, the coal proportion is 76%, higher than the world average of about 40%. Thermal power coal accounts for about half of the total coal consumption, the power structure is not

solar power can fill gaps in 2010 once the total energy consumption in China is 32. 500 million tons of standard coal, the coal proportion is 76%, higher than the world average of about 40%. Thermal power coal accounts for about half of the total coal consumption, the power structure is unsustainable. From the point of energy, the solar energy resources can achieve 1 development potential. 7 trillion tons of standard coal, is the only can meet the future energy demand of China's energy forms. This thesis, from the Chinese Academy of Sciences institute of Ma Shenghong electrician more than once in various occasions. According to his idea, the western China with rich resources of light, solar electricity prices in recent years the pace of decline, and the feasibility of uhv dc transmission, solar energy can be competent for the role to solve the problem of power shortages in China. Concrete plans for in the Midwest of Inner Mongolia, the hexi corridor in gansu, ningxia, shaanxi and other desert zone, planning capacity of 60 million kilowatts, covers an area of 2000 square kilometers, transmission through uhv dc transmission channels from 1000 to 2000 kilometers, the electricity to east China, north China, central China, such as electricity shortages exist area. At the same time, he also demonstrates the feasibility of this scheme on the economy. , he thought, with the large-scale application of solar photovoltaic power generation system and the technical progress, the cost will reduce further, unit must invest calculated according to 10000 yuan, the total capacity of 60 million kilowatts, with a total investment of 600 billion yuan. And transmission cost, transmission capacity of 60 million kilowatts, unit km investment reference existing case, the average transmission distance of 1500 km, with a total investment of 171 billion yuan. As a result, solar power base and transmission project total investment 771 billion yuan, less than a year for lack of electricity caused by the economic loss of 800 billion yuan GDP. Two big questions unanswered in the history of the photovoltaic power planning in our country, also have never from the Angle of the layout planning of the country's precedent. Even for solar products prices down price to solve problems, the photovoltaic (pv) power 'China send proposal is still faced with many practical problems. First of all, how to draw in the west, 2000 square kilometers of land used for construction of photovoltaic power station on the ground. Land problem has always been a project developers in the development of photovoltaic power station one of the biggest headaches in China. Because our country did not form a mature system of photovoltaic power plant development, LED street lamp, examination and approval procedure complex, there is no law provision to this provision, even the gobi and desert, life is still unknown, which makes investors. Second, photovoltaic power station grid encountered problem in China is not only technical, but also policy. How to make in the field of traditional energy sources has to enjoy the interests of the state power group and power grid company for photovoltaic 'net' side, allocating more resources and funds to help photovoltaic power station to realize interconnection is also a big problem. In addition, with wind power due to the unstable and called 'junk' electricity photovoltaic power how to implement effective access to the Internet problem has not been fully resolved. Conclusion: although the proposal has many, but it is for us to solve the problem of power shortages and the Chinese photovoltaic industry overcapacity provides a solution to the problem. However, the general direction of development of domestic pv market can't be wrong, xd to east direction will not wrong, more can't go wrong direction for the development of green energy. Such a scheme, is worth us to call for and support.
