Renewable energy: how to "vases energy" to the dominant energy

First post by: www.itbattery.com

At present, the international oil prices continued to rise, energy supply growing tensions, the deteriorating environmental conditions, many countries have begun to attach Toshiba Satellite A10 Series Battery importance to research and development of renewable energy. In China, with the rapid socio-economic development, energy and the environment for sustainable development has become increasingly serious constraint. In light of these problems, the reporters here at Toshiba Satellite A100 Battery the General Assembly on an interview with academicians of the Chinese Academy of Engineering, Energy and Mining Engineering academician of Huang Lai. Academician Li Huang, to energy conservation, demand total control, development of clean energy technologies, accelerate the development and utilization of renewable energy, optimizing energy structure, to fill the gap of conventional energy, environmental protection and reduction of greenhouse gas emissions an important way to the achievement of China's economic and social The only way to sustainable development. The development of the road map Although coal and oil and gas in the future is still quite a long time, major energy Toshiba Satellite A70 Battery, but China's oil and gas "reserve-production ratio" has reached the Toshiba Satellite A75 Battery warning line, coal, "reserve-production ratio" is also far lower than the level in most countries. In response, Huang Li academicians, on China's renewable energy development need to establish a more positive goals, he will this goal can be summed up as the road map renewable energy development, renewable energy will gradually be added by upgrading to energy alternative sources of energy, The mainstream of energy and one of the leading energy. Huang Li-academician of the road map to the specific details were described: the recent (around 2010), non-hydro renewable energy strategic positioning is to add energy, can provide 060 million tons of Toshiba Tecra 8000 Battery standard coal equivalent of energy demand, accounting for the proportion of the total energy demand 2%: the medium-term (before and after 2020), non-hydro renewable energy is the strategic positioning of alternative energy sources, can provide 180 million -3.3 million tons of standard coal equivalent, the country's total energy demand of 5% -10%; long-term ( Before and after 2030), non-hydroelectric renewable energy strategic Toshiba Tecra 8100 Battery positioning is one of the mainstream of energy, to meet the 400 million -8 100 million tons of standard coal equivalent of energy demand, the country's total energy demand of around 10% -19%; long-term ( Before and after 2050), renewable energy is of strategic positioning one of the leading energy, to meet the 880 million -17.1 million tons of standard coal equivalent of energy demand, the country's total energy demand of 17% -34%. Weak "vases energy" Although the Government has to recognize that forward-looking development of renewable energy resources and strategic significance, and January 1, 2006 promulgation and implementation of the "People's Republic of China Renewable Energy Law," a number of other laws and regulations have also introduced, but some industries and regions Unclear in resources, industrial and other issues remained to be resolved weak circumstances, a quick success and disorderly development of symptoms, the need for scientific guidance. In addition, as the future direction of energy development, renewable energy in the early stage of development there are still some inadequacies, through economic and technological development so that it gradually rationalized. To solar energy as an example, Huang said Academician Li, solar cells in the production process will emit silicon tetrachloride, environmental pollution and, using solar energy is much higher than the cost of coal-fired electricity; In addition, from solar energy to supply patterns That the lack of stability. Again, bio-energy in the production process, the diversified technology will cause the diversification of products, some technologies such as methane gas produced only a low utilization rate of resources products, comprehensive utilization efficiency is not high compared with coal, bio-energy production Scattered distribution of raw materials, mining and use of high cost of transport. The development and use of water involved immigration, environmental protection and watershed issues such as distribution of economic benefits. "Every may Toshiba Tecra 9000 Battery foster a lack of new projects," Huang Li said. Development should have focused on Academician Li Huang, a family of renewable energy in hydro, wind, solar, biomass and other claims, and should be a clear development of their strategic focus. For example, wind power should be "land-based and network-based, pay attention to the development of distributed, speed up industrial building" solar energy should be "mandatory to promote the construction and use of the thermal technology, solar photovoltaic industry chain on the balanced development "Hydropower should be in protecting the environment and ecology on the basis of active and orderly development. For the current concern to the international community of higher bio-energy development model, Huang Li academicians believe that we should "not with the people for grain, and grain is not in dispute" and "not an agricultural land and water, not fight with livestock feed to ensure that food Security "under the premise of multi-start, with the passage of time, non-grain liquid fuels and alternative oil-based products will become of strategic focus. Specifically, the recent can use more mature type of non-food starch and sweet sorghum production of ethanol, a large-scale production, promote long-term study can be considered second generation of bio-liquid fuel technology, agriculture, forestry, waste utilization in the production of cellulose Bioethanol and biodiesel, the scale of alternative fuel oil to protect the security of energy supplies to contribute. "Fossil energy is the sun yesterday to give our mothers, renewable energy is the sun today to give our mother. A new energy revolution will occur, we can better use of renewable energy, fossil energy left to future generations." Huang Lai Academician said.
