International Energy Network News: Experts said that the development of non-food bio-energy not only does not affect food security, but also can effectively use waste resources to replace traditional fossil energy, promote environmental protection and energy-saving emission reduction. At present, countries are stepping up their efforts in bio-energy, especially advanced biology. Fuel development and investment.
The non-grain bio-energy raw materials mainly come from agricultural and forestry organic waste, including straw, livestock manure, forestry residues, etc., as well as energy plants planted on marginal land, including sweet sorghum, cassava, woody oil plants, and shrubs. Shi Yuanchun, an academician of the Chinese Academy of Sciences and the Chinese Academy of Engineering, said that in the development of renewable energy alternatives to fossil energy, the use of bioenergy is the mainstream of the world.
In May 2008, the United States Congress passed a bill including the accelerated development of bio-energy, requiring that after 2018, the consumption of fuel extracted from oil be reduced by 20% and replaced by bio-fuel. According to the “2010 US Energy Outlookâ€, by 2035, the available biofuels in the United States will meet the overall increase in the demand for liquid fuels, and ethanol will account for 17% of the oil consumption, making the US’s dependence on imported crude oil drop to 45% in the next 25 years. From 2008 to 2035, non-hydro renewable energy resources in the United States will account for 41% of the growth of power generation, of which the largest proportion of biomass power generation is 49.3%.
All of Brazil’s gasoline has been forced to add 25% of ethanol. From 2010, the proportion of biodiesel in all ordinary diesel has also reached 5%, which entered the B5 era three years in advance. With the trump card of bioenergy, the Brazilian government has expressed confidence that it will achieve its goal of reducing emissions by 36% by 2020.
In 2004, India began the "silent **" in the oil and agriculture sector. It formulated a decree that a 10% ethanol must be added to the nation's transportation fuels in 2011, and offenders will be prosecuted.
In Sweden, biomass heating generates 103 billion kWh, accounting for 16.5% of the country's total energy consumption and 68.5% of total heating energy consumption. The Swedish capital Stockholm has about 100,000 clean energy cars, including cars using ethanol, biogas cars and hybrid cars, which account for 11% of the total number of cars. Sweden plans to fully use biofuels in the transportation sector by 2020 and take the lead in the post-petroleum era.
Denmark is preparing to gradually reduce and phase out coal-fired power stations in the top five cities in the country, require power stations to carry out technological transformation, use biofuels instead of coal and fuel oil, as the main source of energy for urban production and living.
China's energy supply is tight. The most important thing is oil. In 2010, the foreign oil dependence is expected to reach 55%. Li Shizhong, deputy director of the Institute of Nuclear Energy, Tsinghua University, said that although it is possible to develop electric or hydrogen-powered clean energy vehicles, they are all secondary energy; they can also be converted to liquid fuels using coal, but the energy and environmental costs are too high. . Biofuels can adjust the structure of transportation fuels, increase the proportion of clean fuels, and reduce greenhouse gas emissions. At the same time, it can be combined with agroforestry to play an important role in driving the development of agriculture, rural areas and farmers.
Shi Yuanchun said: “We must fight the banner of energy transition as soon as possible, make a determined effort to effectively speed up the substitution of clean energy for fossil energy, and take a passive and active turnaround. In renewable energy, biomass energy It has a unique position, the most abundant resources, and the greatest influence, especially for the relief of China's "three rural" dilemmas. It should become the strategic subject of China's energy transformation and clean energy, and we must eliminate misunderstandings and strengthen our confidence."
