Energy is the material basis of human survival, is the basic support of the national economy. Our country is a big country of energy consumption, energy supply is mainly dependent on fossil fuels such as coal, oil and natural gas, while the limited resources of fossil energy resources and the enormous pressure on the environment, which seriously restrict the sustainable development of economy and society. In this situation, the development of clean renewable energy has become an urgent issue in the field of energy in China.

To maintain and improve the economic and ecological environment, to maintain and improve the overall planning of production structure and product layout, to reduce fuel, fertilizer, feed and other raw materials, to obtain the output of the product development, ecological environment protection, energy recycling, economic benefits of the four integrated effect. The system can reduce fuel, fertilizer, feed and other raw materials.

"To strengthen the development and utilization of renewable energy is the only way to deal with the increasingly serious energy and environmental problems, but also the only way to realize the sustainable development of human society." "National economic and social development five eleventh year plan" clearly put forward to "accelerate the development of biomass energy". The CPC Central Committee and State Council on solid positive development of modern agriculture and promoting new socialist countryside construction of a number of opinions "put forward," bio energy, bio products and biomass materials as the main content of the biomass industry is to expand agriculture, promote the use of resources of sunrise industry ", start crop straw briquetting fuel processing pilot project," to encourage local conditions the use of barren hills, wasteland and other resources in the development of biomass feedstock for planting. " Since 2013, the State Council promulgated the "opinions on accelerating the development of energy-saving environmental protection industry", "energy-saving emission reduction" "Twelfth Five Year Plan", "Twelfth Five Year" energy-saving emission reduction comprehensive work plan "and other policies, covering the financial incentives, tax incentives, financial innovation and many other aspects, we should vigorously promote the contract energy management mechanism, accelerate the development of energy industry.

2014 policy support again overweight, administration of Taxation and the national development and Reform Commission jointly issued the "on the implementation of energy-saving emission reduction and enterprise contract energy management project of enterprise income tax preferential policy about management issues of the collection of the notice", No. 77 announcement). Announcement made it clear that the number of documents did not account for many of the practical operational aspects of the problem, is the document of 110 supporting regulations. 77 announcement of the introduction of the contract energy management in China's development history of another major milestone, will greatly promote the healthy development of energy management in china. The "12th Five Year" energy saving and environmental protection industry development plan "proposed in 2015, energy-saving environmental protection industry output value reached 4.5 yuan, an increase of 2% of GDP. In environmental event driven and policy support, energy saving and environmental protection industry investment growth accelerated significantly. Industry analysis, in the continuing role of good policy, is expected to continue to maintain high growth in the energy conservation and environmental protection industry in 2014, the total output value will continue to grow more than 30%. To actively implement the Party Central Committee and the State Council on the development of agricultural biomass energy, according to the "renewable energy law", the Ministry of agriculture to develop the "agricultural biomass production development plan" (2007-2015) and other policies, policies and planning are required to increase research and development efforts to accelerate the production rate of biomass energy.
