Ecosystems and other self-organizing systems develop system designs and mathematics that reinforce energy use, characteristically with alternate pulsing of production and consumption, increasingly recognized as the new paradigm. Insights from the energetics of ecological food chains suggest the need to redefine work, distinguishing kinds of energy with a new quantity, the transformity (energy of one type required per unit of another). Transformities may be used as an energy-scaling factor for the hierarchies of the universe including information. Solar transformities in the biosphere, expressed as solar emjoules per joule, range from one for solar insolation to trillions for categories of shared information. Resource contributions multiplied by their transformities provide a scientifically based value system for human service, environmental mitigation, foreign trade equity, public policy alternatives, and economic vitality.
生态系统和其他自组织系统发展出强化能源利用的系统设计和数学方法,其特点是生产和消费交替脉动,这日益被视为新范式。生态食物链能量学的见解表明,有必要重新定义功,用一个新的量——能值(每单位另一种类型的能量所需的一种类型的能量)来区分不同种类的能量。能值可用作包括信息在内的宇宙层级的能量缩放因子。生物圈中的太阳能值,以每焦耳的太阳能焦耳数表示,范围从太阳辐射的1到共享信息类别的数万亿。资源贡献乘以它们的能值,为人类服务、环境缓解、对外贸易公平、公共政策选择和经济活力提供了一个基于科学的价值体系。
