Wind power installed five years doubled
At present, energy security, environment pollution and climate warming has attracted more and more widespread concern in the international community, and actively promote the energy revolution, vigorously develop new energy and renewable energy, has become a significant strategic choice for countries around the world to seek way to sustainable development and foster new economic point of growth. Since China’s reform and opening up, to achieve rapid economic growth at the same time, also paid a very high cost of resources and environment.
First, the development of wind power is an inevitable choice for China to implement sustainable energy strategy
1, the reduction of energy resources to seek new energy sources
Energy global energy crisis, energy is indispensable to the existence and development of human society. Expected by 2025, global energy consumption than in 2001 increased by 54 percent, the national industrial energy consumption to grow at a rate of 1.2% per year, including China and India, Asian developing countries in energy consumption will than the current growth doubled, the share of global energy demand growth of 40% of the amount and the developing growth of 70%. In the face of global economic and population growth of energy demand, traditional energy exhaustion, the deterioration of the environment for human survival, development of clean and renewable energy is the only way for the sustainable development of mankind.
2, the current status and potential of conventional energy
Coal is the most important energy resource in China, which occupies an absolute dominant position in China’s energy resources. According to 10 million tons of coal production in 2000 calculation, China coal resources proved maintain assurance level of reserves of up to 10 years, the economic development of remaining recoverable reserves, the level of assurance for 114 years.
China’s total oil resources in the amount of about 10 billion tons of proven reserves, of which 160 million tons; 38.14 trillion cubic meters of natural gas, the amount of the total resources in proven reserves, of which 2.06 trillion cubic meters. Oil and natural gas proved reserves in the energy resources in the total proven reserves structure respectively accounted for 2.8% and 0.3%, in the world of similar oil and gas reserves accounted for 2.0% and 0.5%.
The rapid increase in the demand for energy consumption, so that the conventional energy is facing the depletion of the crisis. If the 2009 energy proved reserves, production and consumption as the basis, China’s proven reserves of conventional energy sources can only mining and insufficient consumption of 35 years, and the figure of the world average is only less than 80 years. No major energy found or energy consumption structure without major changes in the, conventional energy around the world within the next 100 years consumed, while the oil may is the first depleted of energy.
3, the most commercial potential of new energy – wind power
According to the International Energy Agency estimates that wind power growth are in more than 30%, to 2020, the world’s wind power installed capacity will reach 12 million kilowatts, annual generating capacity will reach the world power to 12% of the total demand.
This shows that China’s wind energy resources have a great potential for commercialization and scale development. The most important thing is to break the bottleneck of industrial development and utilization of wind energy, carefully nurture and care market. Wind energy cost is relatively low, has become the first choice for each country competing for the development of new energy.
Two, China’s wind resource distribution
On the regional distribution, China’s wind energy is mainly distributed in the following areas:
1, the southeast coast and its islands, for China’s largest wind resource area
2, Inner Mongolia and Northern Gansu, China’s second large wind energy resource area
3, Heilongjiang and Jilin and the eastern coast of Liaodong Peninsula, wind energy is also larger
4, the Tibetan Plateau, and the coastal areas of the northern North Wind, large area
5, Yunnan, Guizhou, Sichuan, Gansu, southern Shaanxi, Henan, Hunan western, mountainous areas of Fujian, Guangdong, Guangxi, and the Tarim Basin, the smallest wind area.
6, in the vast areas outside the 4 and 5 areas, for the wind energy seasonal utilization
Three, China vigorously develop wind power barriers and measures
With the constant expansion of wind power installed capacity, wind power development has encountered new contradictions and problems.
First of all, from the view of market demand, to the difficult problem of grid connected wind power.
Especially rich in wind energy resources of the “Three North” (northeast, North and northwest) regions generally appear serious abandoned wind phenomena. Especially in the winter heating period, in order to meet the needs of heating, priority should be given to the security operation of the cogeneration units, occupying the nighttime load space, wind forced a large number of abandoned wind, some places abandoned wind power has more than 50%.
Abandoned wind problem, does not mean that China’s wind power construction, but exposes the contradictions and problems in the management of our country electric power. In the construction of wind power concentrated in the “Three North” area with good wind resources, electricity load in these areas is relatively small, in the local consumptive difficulties; intermittent of wind energy resources and stochastic characteristics, operation and management to power system increased difficulty; affected by the generation scheduling management system restricts and local protectionism, and online examination and approval system of electricity price constraints, greatly affected the area between the electric power and the reasonable exchange.
Secondly, the policy of supporting the development of wind power has also exposed some problems.
First, the wind power tariff subsidies. The wind power tariff concessions is common practice in the world, but part of the preferential price subsidy funding and management are different. Adopted in the United States is tax deductible policy provisions give subsidies 2.1 cents per kWh of wind power generating capacity, by the wind power investors the tax deductible; Australia is the quota system, the provisions of the sale of electricity enterprises in the sale of electricity must have a certain proportion of renewable energy generating capacity, by the sale of electricity companies to renewable energy power generation enterprises to buy
