prospect of new energy
Despite the short-term coal, oil, natural gas and other traditional energy sources are still the main force of China’s energy supply, but in the long term, low-carbon energy structure is the trend of development. 2009 Central Economic Work Conference stressed that the current Chinese economy, “Paul growth” has achieved remarkable results, and are in a critical time of structural adjustment, for the future long-term development, to improve the quality and efficiencyDell Inspiron 6000 battery， Dell Inspiron 6400 battery，Dell Inspiron 700m battery， Dell Inspiron 8500 battery of economic growth will do more. Thus, hydropower, nuclear, solar, wind and other new low-carbon energy is the development direction of China’s energy future.
The new rich in energy resources and huge potential for
From a resource perspective, many of China’s new energy resources are very rich, future development potential.
According to a 2003 review of the outcome of water resources, China’s installed capacity of hydropower resources in technology development for the 542 million kilowatts, the economy can be developed installed capacity of about 400 million kilowatts. According to the economic exploitable annual power output re-use 100-year period, water resources accounting for the total of China’s energy remaining recoverable reserves of 40% of conventional energy resources in China ranks second only to coal.
According to “China’s Energy Development Report 2009,” the statistics, China’s land, 10 meters above ground height of the wind energy resource theory calculation of reserves of about 43 million kilowatts. Technology can be developed is about 380 million kilowatts, technology development area of about 20 million square kilometers. Coastal 5-20 m deep in the vast sea area, 10 meters of available wind energy resources is about more than 700 million kilowatts. View from our wind energy resources, wind power may well become the thermal power, hydro power after the third-largest.
Similarly, China’s abundant solar energy resources. The total amount of solar radiation in the 120 ~ 280 W / m, between 2 / 3 of the land area and the number of annual sunshine hours in more than 2200 hours, the annual total amount of solar radiation 5,000 trillion joule per square meter than, equivalent to 170 kilograms of standard coal .
Biomass energy in China has great development potential. According to “report” to statistics, China’s annual energy use can be used as crop straw resources of approximately 150 million tons of standard coal, forest residue resources of approximately 200 million tons of standard coal, Jatropha curcas, jatropha, rapeseed, castor-oil plant energy crops such as oil-bearing plants and the potential acreage to meet the annual output of 50 million tons of raw materials of biological liquid fuel requirements. Industrial organic waste water and livestock farm waste to produce methane gas each year the amount of resources theory, nearly 80 billion cubic meters, equivalent to 60 million tons of standard coal.
My Government attaches great importance to the development of new energy sources not only a clear strategic positioning and put forward specific development goals, but also established a system-wide policy and institutional framework to enable rapid development of new energy industries. By the end of 2008, cumulative total installed hydropower capacity of 172 million kilowatts, the annual generating capacity reached 563.3 billion kilowatts hours, accounting for 16.3% of total electricity generation capacity. 2008 new wind power installed capacity of about 600 million kilowatts, cumulative wind power Dell Inspiron 8600 battery， Dell Inspiron 9200 battery， Dell Inspiron 9300 battery capacity reached 12.17 million kilowatts. Solar photovoltaic cells significantly increased production capacity has reached an annual output of 4 million kilowatts capacity of photovoltaic cells to become the world’s largest producer of solar photovoltaic cell products. Annual production capacity of solar water heaters has reached 40 million square meters, the cumulative use of solar water heaters more than 125 million square meter, representing the world’s total use of solar water heaters more than 60%. 2008 nuclear power generation capacity of 68.4 billion kilowatts hours, an increase of 11.6%. Had a greater development and utilization of biomass energy development, including household biogas digesters to reach about 140 billion cubic meters.
Speed up the development of R & D breakthroughs in bottleneck
Hydropower is currently the most mature new energy in China, most large-scale development of conditions for renewable energy. With the national economic development and growing electricity demand and the increasing power quality requirements, hydropower’s role in the power system will be gradually strengthened, and our next step must be to speed up the process of development and utilization of hydropower. According to statistics, in 2008 China’s new approval of nine hydropower installed capacity reached 9.668 million kilowatts.
Wind power in China’s rapid development in recent years has been to double the installed capacity for five consecutive years. However, generally speaking, China’s wind power technology research and development capability is relatively weak, the lack of independent development of new technologies and new products, ability to rely mainly on foreign technology. The next step China should continue to strengthen basic research in wind power technology, wind power for China’s own development efforts. At the same time, we should strengthen the construction of wind power management, and adhere to the way of wind power concession to build large wind farms, according to “integrate into the bulk power system and building a big base” requirements, and strive to use more than 10 years time in Gansu, Inner Mongolia, Hebei, Jiangsu, to the formation of a few on the 10 million kilowatts of wind power base level.
China is the world’s few nuclear industry has a relatively complete system in the world. Nuclear power plant is most similar thermal power generation method is different is that it is based on nuclear reactors to replace the power plant boilers. For a long time, China’s coal-fired electricity generation accounted for 80% of the total generating capacity over to the coal production, transportation and environmental protection has brought great pressure. Therefore, the next step China should continue to foster domestic production of nuclear energy capabilities, and strive to quickly develop a large-scale batch of Chinese brand-building ability of nuclear power plants.
Solar energy is the world’s most resource-rich energy resources, China should be utilization of solar energy technology as a strategic energy technology, steady development, and actively promote. On the heat consumption, an area of large government buildings, commercial buildings to gradually promote the installation of solar water heaters. Start solar power demonstration projects to carry out urban rooftop solar photovoltaic power generation application demonstration projects to promote solar silicon materials technology R & D and industrialization.
The use of biomass energy development, can improve the quality of life for farmers, improving rural production and living environment, and accelerate the process of urbanization in rural areas. If China is to carry out bio-energy resource assessment, organizational development of biomass energy development and utilization planning. Speed up the upgrading of rural biomass energy utilization technologies, development of efficient direct combustion technology, power generation technology, gasification and liquefaction technology, the development focused on aquaculture plant gas to generate electricity and improve the formation of biomass industry service system.
Also beware of the rapid development of overcapacity
Along with the increased investment in new energy sources, repeated construction, excess capacity and other issues began. September 26, the State Council approved and transmitted the National Development and Reform Commission and other departments “on the curb overcapacity in some industries and redundant construction and guide the healthy development of industry, a number of views.” In the “opinions” are listed in six categories overlap construction, industry overcapacity, the polysilicon, wind power equipment, two new energy-related industries and ranked them impressively.
According to “opinions” of the statistics, in 2008 China’s polysilicon capacity of 2 million tons, output of 4,000 tons or so, under construction production capacity of about 8 million tons, production capacity has been a marked excess. Polysilicon is a high energy-consuming and high pollution products, from production of industrial silicon solar cells to the whole process of integrated power consumption of about 2.2 million kilowatts hours / MW. However, the slow profile development of China’s photovoltaic power generation market, the domestic solar cell 98% for export, equivalent to export large amounts of domestic shortage of energy.
In recent years, the rapid development of wind power industry, there has been wind power equipment investment rush into mass action, repeat the phenomenon of the introduction and redundant construction. At present, China’s wind turbine manufacturing machine has more than 80, there are many companies ready to enter the wind power equipment manufacturing industry, 2010, China’s wind power equipment, production capacity of more than 20 million kilowatts, and the annual wind power installed capacity of 10 million kilowatts so, if not timely regulation and guidance, excess capacity will be inevitable.
The present stage, China should intensify efforts to expand domestic photovoltaic market, support the use of domestic raw materials to produce polysilicon solar cells in order to meet the domestic demand-driven. At the same time, we must strictly control the energy shortage, high price areas of new polysilicon projects, the lack of supporting comprehensive utilization, environmental protection and non-compliance of polysilicon projects not approved or filed, encourage production of polycrystalline silicon solar cell manufacturing enterprises and downstream enterprises to enhance joint and co-operation, extend the industrial chain.
China would also like to seize the great efforts to develop wind power and other renewable energy historic opportunity to China’s wind power equipment manufacturing industry has developed into independent innovation capability and international competitiveness of emerging industries. Strictly control the wind power equipment, the blind expansion of production capacity, optimize the industrial structure, and maintaining market order. We should actively promote large-scale wind power equipment industry and international, foster international competitiveness of wind power equipment manufacturing industry.
From this year’s “guarantee growth” into next year’s “promoting change”, a new change in our economy will inevitably put forward new demands on the energy sector. In such a situation, the new energy will become the focus of future development, support to achieve long-term development of China’s energy.
