Jevons paradox

Jevons paradox
The Jevons paradox has been used to argue that energy conservation may be futile, as increased efficiency may increase fuel use. Nevertheless, increased efficiency can improve material living standards. Further, fuel use declines if increased efficiency is coupled with a green tax or other conservation policies that keep the cost of use the same (or higher).[3] As the Jevons paradox applies only to technological improvements that increase fuel efficiency, policies that impose conservation standards and increase costs do not display the paradox. History[edit] The Jevons paradox was first described by the English economist William Stanley Jevons in his 1865 book The Coal Question. Jevons observed that England's consumption of coal soared after James Watt introduced his coal-fired steam engine, which greatly improved the efficiency of Thomas Newcomen's earlier design.

Kalundborg Eco-industrial Park Industrial symbiosis network in Kalundborg, Denmark View from around the Asnæs power station. Kalundborg Eco-Industrial Park is an industrial symbiosis network located in Kalundborg, Denmark, in which companies in the region collaborate to use each other's by-products and otherwise share resources. History[edit] The Kalundborg Industrial Park was not originally planned for industrial symbiosis. The park began in 1959 with the start up of the Asnæs Power Station. Since then, the facilities in Kalundborg have been expanding, and have been sharing a variety of materials and waste products, some for the purpose of industrial symbiosis and some out of necessity, for example, freshwater scarcity in the area has led to water reuse schemes. A timeline of the creation of the industrial park: The Symbiosis[edit] The relationships among the firms comprising the Kalundborg Eco-Industrial Park form an industrial symbiosis.

Are Market GM Plants an Unrecognized Platform for Bioterrorism and Biocrime? James J. Kay James J. Kay (June 18, 1954 – May 30, 2004) was an ecological scientist and policy-maker. He was a respected physicist best known for his theoretical work on complexity and thermodynamics. Biography[edit] James Kay held a BS in physics from McGill University and a Ph.D. in systems design engineering from the University of Waterloo. His Ph.D. thesis was entitled Self-Organization in Living Systems.[1][2] Much of his work relates to integrating thermodynamics into an understanding of self-organization in biological systems.[3] For example, when water in a pot is heated, it will spontaneously form convection currents such as Bénard_cell. Kay was an associate professor of environment and resource studies at the University of Waterloo, with cross-appointments in systems design engineering, geography, management sciences, and the School of Planning.

Kalmička zajednica u Beogradu Beogradski Kalmici. Iz foto-arhiva Politike. Opis života društvene grupe koja se raspala pre više desetleća i zatim se skoro bez tragova zagubila povezan je, bez sumnje, sa posebno vrućim problemima metodološke i metodičke prirode. Za etnološku struku beogradska kolonija Kalmika, zapadnomongolskog naroda sa područjeg donjeg toka Volge, zanimljiva je kao primer male zajednice u kosmopolitskom velegradu, kao doprinos etnološkom izgledu Beograda i, konačno, kao fragment istorije Kalmika u emigraciji. Većina Kalmika došla je u Jugoslaviju decembra 1920. sa grupom od 22.000 vojnika, u pratnji članova porodice. Tako su u novoj sredini nastavljali tradiciju uzgoja konja, kojim su se bavili na donskim stepama. Neki Kalmici stigli su u Jugoslaviju 1922. godine, kad su iz Vladivostoka morale da se povuku i poslednje protivboljševičke jedinice. Glavnina ruskih iseljenika u Jugoslaviji živela je u Beogradu.

Life-cycle assessment Methodology for assessing environmental impacts Illustration of the general phases of a life cycle assessment, as described by ISO 14040 Life cycle assessment or LCA (also known as life cycle analysis) is a methodology for assessing environmental impacts associated with all the stages of the life cycle of a commercial product, process, or service. An LCA study involves a thorough inventory of the energy and materials that are required across the industry value chain of the product, process or service, and calculates the corresponding emissions to the environment.[2] LCA thus assesses cumulative potential environmental impacts. Widely recognized procedures for conducting LCAs are included in the 14000 series of environmental management standards of the International Organization for Standardization (ISO), in particular, in ISO 14040 and ISO 14044.

Effects of pesticides on our wildlife | Policy and insight We know pesticides harm bees – the evidence is compelling. What about other wild species? When I searched for the effect of pesticides on wildlife, I couldn’t find a good summary so I produced this one. In our new report 'Problems with Pesticides' I’ve pulled together the main findings of recent scientific studies and reviews of evidence from the UK and beyond. From butterflies, beetles, damselflies and hoverflies to earthworms, hedgehogs, frogs and fish – not forgetting the impact on our water and soils – the evidence shows that problems with pesticides go well beyond bees. ...many species have struggled as their habitats have shrunk and climate change and pesticide use have taken their toll. Bees and beyond It’s well known that bees are in trouble and their exposure to pesticides isn’t helping. Pesticides include chemicals that kill insects (insecticides), plants (herbicides) and fungi/moulds (fungicides). They may be unintended victims but are affected because: Key findings: Earthworms

ISASMELT Smelting process The installed feed capacity of Isasmelt furnaces has grown as the technology has been accepted in smelters around the world. Graph courtesy of Xstrata Technology. The ISASMELT process is an energy-efficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines (a subsidiary of MIM Holdings and now part of Glencore) and the Government of Australia’s CSIRO. ISASMELT technology has been applied to lead, copper, and nickel smelting. Smelters based on the copper ISASMELT process are among the lowest-cost copper smelters in the world.[2] The ISASMELT furnace[edit] An ISASMELT furnace is an upright-cylindrical shaped steel vessel that is lined with refractory bricks.[3] There is a molten bath of slag, matte or metal (depending on the application) at the bottom of the furnace. Cut-away view of an Isasmelt furnace. The products are removed from the furnace through one or more "tap holes" in a process called "tapping". AGIP Australia[edit]

Idemo 200 na sat ili i dalje „jurimo 30“ - dokle je sve trebalo da se stigne „brzom prugom Srbije“ - BBC News na srpskom Image copyright Getty Images Od Beograda do Budimpešte već više od godinu dana stiže se brzom prugom za dva i po sata. Voz se kreće prosečnom brzinom od 200 kilometara na sat, a Beograd i Novi Sad udaljeni su svega 30 minuta. Rekonstrukcija pruge Beograd - Bar uveliko je u toku, a i vagoni od Sente do Subotice putuju obnovljenim kolosecima. Ovo nije alternativna istorija za ljubitelje vozova u Srbiji. Šta je sve obećano u železničkom saobraćaju, do kad je trebalo da bude gotovo i da li je nešto počelo i da se ostvaruje? Od Beograda do Budimpešte 200 na sat Predsednik Srbije Aleksandar Vučić je 2015. bio premijer i jedno od obećanja dato građanima je da će moći da koriste modernizovanu brzu prugu Beograd - Budimpešta od 2018. Skoro četiri godine kasnije, ministarka saobraćaja Zorana Mihajlović je u oktobru odredila novi rok - jesen 2021. godine. „Radovi bi trebalo da počnu krajem marta ove godine i rok je 33 meseca", navodi se u odgovoru. Nije samo Srbija usporila sa obećanjima. Nema kašnjenja

Famous Edgar Allan Poe Stories Read by Iggy Pop, Jeff Buckley, Christopher Walken, Marianne Faithful & More In 1849, a little over 167 years ago, Edgar Allan Poe was found dead in a Baltimore gutter under mysterious circumstances very likely related to violent election fraud. It was an ignominious end to a life marked by hardship, alcoholism, and loss. After struggling for years as the first American writer to try and make a living from his art, and failing in several publishing ventures and positions, Poe achieved few of his aims, barely getting by financially and only managing to attract a little—often negative—notice for now-famous poems like “The Raven.” But of course, as we know, a countercurrent of Poe appreciation took hold among writers, artists, and filmmakers interested in mystery, horror, and the supernatural—to such a degree that in the previous century, nearly every artist even passingly associated with darker themes has interpreted Poe as a rite of passage.

Life-cycle engineering Life-cycle engineering (LCE) is a sustainability-oriented engineering methodology that takes into account the comprehensive technical, environmental, and economic impacts of decisions within the product life cycle. Alternatively it can be defined as “sustainability-oriented product development activities within the scope of one to several product life cycles.”[1] LCE requires analysis to quantify sustainability, setting appropriate targets for environmental impact. The application of complementary methodologies and technologies enables engineers to apply LCE to fulfill environmental objectives. Quantifying environmental sustainability[edit] An example of planetary boundaries The first step in completing LCA or LCE is determining the appropriate sustainability thresholds to use as environmental targets for the product system. Complementary methodologies and technologies[edit] Modern technology provides innovative new opportunities for LCE: Key themes in life cycle engineering[edit]
