This preview shows page 10 - 11 out of 31 pages.

e-cycling– recycling electronic waste.effective rainfall– the volume of rainfall passing into the soil; that part of rainfall available for plantuse after runoff, leaching, evaporation and foliage interception.energy efficiency- using less energy to provide the same level of energy service.effluent- a discharge or emission of liquid, gas or other waste product.El Niño- a warm water current which periodically flows southwards along the coast of Ecuador andPeru in South America, replacing the usually cold northwards flowing current; occurs once every fiveto seven years, usually during the Christmas season (the name refers to the Christ child); the oppositephase of an El Niño is called a La Niña.embodied energy- the energy expended over the entire life cycle of a good or service cf. emergy.emergent property– a property that is not evident in the individual components of an object orsystem.emergy– “energy memory” all the available energy that was used in the work of making a productdirectly and indirectly, expressed in units of one type of available energy (work previously done toprovide a product or service); the energy of one type required to make energy of another.emission standard- a level of emissions that, under law, may not be exceeded.emissions intensity– emissions expressed as quantity per monetary unit.emissions trading– see carbon trading.emissions- substances such as gases or particles discharged into the atmosphere as a result of naturalprocesses of human activities, including those from chimneys, elevated point sources, and tailpipes ofmotor vehicles.endangered species– a species which is at risk of becoming extinct because it is either few innumber, or threatened by changing environmental or predation parameters.energetics– the study of how energy flows within an ecosystem: the routes it takes, rates of flow,where it is stored and how it is used.energy- a property of all systems which can be turned into heat and measured in heat units.*available energy– energy with the potential to do work (exergy);*delivered energy– energy delivered to and used by a household, usually gas and electricity;*direct energy- the energy being currently used, used mostly at home (delivered energy) and forfuels used mainly for transport;*embodied energy- t the energy expended over the entire life cycle of a good or service OR theenergy involved in the extraction of basic materials, processing/manufacture, transport and disposal ofa product OR the energy required to provide a good or service;*geothermal energy– heat emitted from within the Earth’s crust as hot water or steam and used togenerate electricity after transformation;*hydro energy– potential and kinetic energy of water used to generate electricity;*indirect energy– the energy generated in, and accounted for, by the wider economy as aconsequence of an agent’s actions or demands;*kinetic energy- the energy possessed by a body because of its motion;*nuclear energy- energy released by reactions within atomic nuclei, as in nuclear fission or fusion
