Opportunities and challenges for a sustainable energy future   总被引:6,自引:0,他引:6  
S Chu  A Majumdar 《Nature》2012,488(7411):294-303
Access to clean, affordable and reliable energy has been a cornerstone of the world's increasing prosperity and economic growth since the beginning of the industrial revolution. Our use of energy in the twenty-first century must also be sustainable. Solar and water-based energy generation, and engineering of microbes to produce biofuels are a few examples of the alternatives. This Perspective puts these opportunities into a larger context by relating them to a number of aspects in the transportation and electricity generation sectors. It also provides a snapshot of the current energy landscape and discusses several research and development opportunities and pathways that could lead to a prosperous, sustainable and secure energy future for the world.  相似文献

Sustainable development is a concept, which involves social, ecological and economic objectives, and requires to sustain the integrity of resources exploitation, the direction of investments, the orientation of technological development and institutional change. Although there is still much confusion and conflict about exact meaning of sustainable development, many agree that sustainable development is about satisfying social, environmenta l, and economic goals. While th e concept is generally accepted and relatively easy to comprehend, the difficulty arises in trying to apply the principles of sustai nable development in practice. One of the difficulties is need to measure the “level of sustainability”. The desirable characteristics for sustainability indicators have to include: simple to calculate, useful for decision making, and robust in indicating progress towa rd sustainability. The exergy analysis a pproach based on full life cycle assessment (LCA) of the materials and technologies is a useful metrics to evaluate mitigation of green house gas (GHG) emissions associated with industrial eco materials and technologies. The metrics is used for reducing dimensionality on the input side by combining material and energy streams and out put side reducing different characterisation factors to a single “unsustainability” indicator in a theoretically rigorous manner. The adopted approach has been illustrated on a few examples associated with Australian aluminium industry.  相似文献

地理学的终极关怀本质上是一个人文关怀,从地理学的角度看,人类的可持续发展问题,事实上就是人作为类存在物在地球表面这个空间系统中的可持续发展问题,正是由于地理学的独特的研究对象使其在人类可持续发展问题上具有独特的价值,这不仅可使可持续发展问题被包含在地理学的终极关怀之中,而且也将为可持续发展提供一个重要的地理学的科学图景。  相似文献

Neoproterozoic magmatic activity and global change   总被引:36,自引:10,他引:26  
Neoproterozoic is a very important time in the history of the Earth, during which occurred supercontinent breakup, low-latitude glaciation, and biotic diversification.These concern a series of interdisciplinary studies involving ancient plate motion, climate change and life evolution, resulting in many forefront topics of general interest in the earth sciences. These include exact ages bracketing the Cryogenian System and glaciations, initial age and lasted duration of supercontinent breakup, dynamic reconstruction of China continents in supercontinental configurations, the nature of rift magmatism and extent of hydrothermal alteration, paleoclimatic implication of water-rock interaction and Iow-^18O magmatism, and relationship between supercontinental evolution and global change. A number of outstanding advances in the above aspects have being made by Chinese scientists, leaving many important issues to be resolved: (1)did the Cryogenian start at either 800 to 820 Ma or 760 to 780 Ma? (2) was South China in the supercontinental configuration located in either southeast to Australia or north to India? (3) are Paleoproterozoic to Archean ages of crustal rocks a valid parameter in distinguishing North China from South China? Available observations suggest that Neoproterozoic mantle superwelling occurred as conspicuous magmatism in South China but as cryptical magmatism in North China. Mid-Neoproterozoic mantle superplume event and its derived rift-magmatism would not only result in the supercontinental demise, but also play a very important role in the generation and evolution of the snowball Earth event by initiating the global glaciation, causing the local deglaciation and terminating the snowball Earth event.  相似文献

尽管可持续发展的概念已被世界普遍接受,但可持续发展的实践成效不大,因此,考究可持续发展的提出及其精神要义,对当今社会的可持续发展实践具有重要的意义,首先,可持续发展观念亘古有之,源远流长,是一个古老常新的话题,其次,可持续发展是在生态危机日益严重的状况下提出的,是人类面对自身生存危机的积极选择,最后,可持续发展观念对消除传统发展观的缺陷具有积极的意义,体现了人类一种全新的伦理精神。  相似文献
