第四次能源变革与生态文明建设

能源在人类发展进程中起着举足轻重的作用。人类文明发展史上已经实现的三次能源变革在加速人类技术进步的同时,使得能源消费出现几何级数的增长,并带来了能源安全、能源贫困、环境污染、气候危机等一系列问题。本文提出,第四次能源变革最大的难点和挑战是解决经济增长与可持续发展的两难问题,同时实现能源生产和能源消费的变革。与以往不同的是,实现新的能源变革不仅要依靠市场经济和技术,更重要的是要通过人类主动选择的新的文明形态来实现。本文同时分析了我国能源消费总量的快速增长和长期以煤为主的能源结构带来的严重问题,提出我国亟需实现能源清洁化、低碳化变革。通过分析我国实现能源变革的机遇和条件,提出了建设生态文明和实现能源变革的相关建议。

促进生态文明建设是国有企业的重要责任

党的“十八大”报告提出“大力推进生态文明建设”,首次把生态文明建设提升到与经济建设、政治建设、文化建设、社会建设相并列的高度,“五位一体”地建设中国特色社会主义.从环境保护到建设生态文明的转变,为国有企业一直肩负的责任增加了新的内涵,国有企业必须成为建设生态文明的主力军、引领者和推动者.国有企业需要通过走生态文明科学发展之路,来满足人民群众日益增长的生态诉求,否则将失去企业生存和发展的基础.同时,走生态文明科学发展之路,也是国有企业在新一轮国际竞争中赢得主动的法宝.国有企业要把生态文明建设贯穿于企业生产始终,抓住契机促进企业技术创新,把生态文明建设作为提升国企形象的重要途径,将生态文明寓于企业文化之中,以实实在在的行动推进绿色发展、循环发展、低碳发展,为早日实现“中国梦”做出自己的贡献.

勇当生态文明建设的践行者

当前,可持续发展正日益成为全国、全球高度关注的热点,开始在一些地方会聚成奔涌浩荡、不可逆转的时代潮流,生态文明已成为响彻中华大地的时代最强音。建设生态文明,关系人民福祉,关乎民族未来,是一项伟大的事业,既需要理论创新,也需要实践创新。     

低碳发展的人文意蕴

阐述了大量事实说明整个地球气候的确正在变暖，地球变暖将不可逆地引起地球深度的改变，从而引发人类灾难性的生态危机，因此整个人类都要携起手来共同应对。引领和倡导低碳发展、循环发展和绿色发展。蕴含着深刻的人文文化智慧，不仅仅是人类共生共存的需要或生态文明的内在需要，也是减轻能源压力和转变生产生活方式的需要；不仅关涉到当代人的可持续发展，也关涉到子孙后代代际间的可持续发展。     

Wind energy and the hydrogen economy—review of the technology

The hydrogen economy is an inevitable energy system of the future where the available energy sources (preferably the renewable ones) will be used to generate hydrogen and electricity as energy carriers, which are capable of satisfying all the energy needs of human civilization. The transition to a hydrogen economy may have already begun. This paper presents a review of hydrogen energy technologies, namely technologies for hydrogen production, storage, distribution, and utilization. Possibilities for utilization of wind energy to generate hydrogen are discussed in parallel with possibilities to use hydrogen to enhance wind power competitiveness.

Refinement of motivity factor in comparison of transportation fuels

Hydrogen is potentially the fuel of the future, with the transition to a hydrogen economy driven by the concerns about the climate change and the depletion of fossil fuel resources. Hydrogen is better than almost all other fuels when the fuels are evaluated on the basis of several metrics, including safety and versatility of use. Hydrogen is also presumed to have a superior motivity factor, a performance measure arising out of a combination of acceleration and drag forces. The motivity factor is quantified on the basis of the gravimetric and volumetric energy densities of a fuel. The present paper offers a refinement of the motivity factor which incorporates the effects of the mass of the storage matrix in these energy densities. It is shown that other fuels may have higher motivity factors than hydrogen when quantified on the basis of these refinements.     

Solar PV energy conversion and the 21st century’s civilization

A review is given on some important roles of the solar PV technology to contribute to the sustainable developments of the 21st century civilization. Firstly, motivations of the industrial developments by energy revolutions since James Watt on steam engine in the 18th century are discussed. The transitions of natural resources from solid (coal) and liquid (oil) to gas (Liquified Natural Gas (LNG), Liquified Petroleum Gas (LPG)) are closely related to not only the economy of mass production, storage and transportation but also environmental issues. Secondly, a brief discussion is given on “the 3E-Trilemma” which is the most important issue for the 21st century’s civilization life. Thirdly, a new strategy for the renewable energy promotion—the so-called Fundamental Principle to promote New Energy Developments and Utilization—and its action planning for PV technology up to the year of 2010 are introduced.In the final part of this paper, a prospect of future industrializations of the photovoltaics is discussed, then the possible new roles to contribute to the global environmental issues by the PV system developments are introduced.     

Some thoughts about the hydrogen civilization and the culture development

Civilization is defined as an aggregate achievement of inventions for realizing lofty human ideas, and culture is defined as the intellectual side. The realization of human ideas is the sustainable development (SD), and one of these pillars is the energy system. The main current of the human energy carriers has made the transition from coal to petroleum, and from petroleum to natural gas. This trend means the transition from the fuels with a larger ratio of carbon to those with a larger ratio of hydrogen. Ultimately, the main energy current will be converged to hydrogen. The hydrogen civilization is about to emerge today. The centripetal force acting upon every fuel toward hydrogen has an intellectual analogy to Brownian motion, which is one of the main topics of the concerned complexity science. Moreover, Ashby's requisite variety law indicates that the civilization must wear the cloth of the culture in order to build up the endlessly sustainable civilization.
