From domestic energy security and environmental impact of two considerations, science and technology have been carried out mostly in developed countries for renewable energy research and market development. The United States has also invested funds to establish a special government fund to promote domestic renewable energy industry.
Renewable energy is sustainable use of energy resources, such as water, wind turbines, solar, biomass and ocean energy, there is no resource depletion problems. In addition to China’s exploitable hydropower installed capacity and annual power generation volume ranking first in the world outside, solar, wind and biomass and other renewable energy resources are also very rich. China’s solar-rich regions than the land area accounts for 2 / 3 of the above, the annual amount of radiation over 6000MJ / ㎡, the surface absorption of solar energy per year is roughly equivalent to 1.7 trillion tce of energy; wind energy resource of about 3.2 billion kW, preliminary estimates of wind energy development and utilization of available resources of approximately 1 billion kW, according to Germany, Spain, Denmark, the rapid development of wind power experience of countries that analogy analysis, China’s volume of resources available for development of wind energy may be more than 3 billion kW; Ocean Energy Resources Technology on the available resources is estimated at about 400 million -5 100 million kW; vision of geothermal resources reserves of 135.3 billion tce, proven reserves of 3.16 billion tce; the existing biomass energy include: straw, firewood, organic waste and industrial organic waste, resources, reached a total of 700 million tce, through variety improvement and expansion of cultivation, the amount of bio-energy resources at this level could be doubled again. In short China’s renewable energy resource-rich, with large-scale development of the resource conditions and technical potential for future social and economic development to provide adequate energy, development and utilization of renewable energy promising.
By the end of 2006, China’s renewable energy consumption Facilitation total 200 million tons of standard coal, (not including the traditional use of biomass), China’s primary energy consumption accounts for about 8% of the total compared to 2005 increased by 0.5 percentage points , which for the 2010 renewable energy accounted for 10% of the national goal of a one-time energy taken a solid step forward.
As more and more countries have taken to encourage renewable energy policies and measures, renewable energy production scale and scope of use is expanding in 2007, the world’s renewable energy generating capacity of 24 megawatts, more than in 2004 by 50%.
In 2007 there are at least more than 60 countries have developed to promote sustainable energy development policies, the EU has been established by 2020 to achieve sustainable energy accounted for 20% of all energy goals, while China also established by 2020 renewable energy the proportion of total energy to 15% target. In 2007, the global grid solar power-generating capacity increased by 52%, wind generators generating capacity increased by 28%. Worldwide there are about 50 million households use solar water heater placed in the roof for hot water, 250 million households use solar lighting, 25 million households using methane for cooking and lighting.
Increase the proportion of renewable energy to pass the “green economy” emerging information, in 2012 “Kyoto Protocol” after the expiry of a new mechanism for greenhouse gas emissions will further promote the green economy’s overall development.
According to China’s long-term energy plan, by 2020, China basically rely on conventional energy sources to meet the economic development and improved living standards in the energy needs by 2020, renewable energy will become increasingly prominent strategic position, when the need for renewable energy to provide hundreds of millions of tons as well as more than 1 billion tons of standard coal energy. Therefore, China’s development of renewable energy strategic objective would be: the ability to maximize the energy supply, improve energy structure, diversify our energy resources to effectively protect the security of energy supply.
