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.

Are Market GM Plants an Unrecognized Platform for Bioterrorism and Biocrime? 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.

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

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.

South-East Europe is burning: how temperatures have risen for the last 117 years / Balkans / Areas / Homepage - Osservatorio Balcani e Caucaso Transeuropa Demonstrations in Sofia (photo: Francesco Martino) The effects and risks of climate change are felt in the Balkans too, but dealing with the issue is often "left behind". EDJNet analysed the increase of temperatures in the cities of South East Europe since 1900 In December 2015, with the signing of the Paris agreement, 195 countries committed to "limiting the increase in temperature to 1.5°C compared to pre-industrial levels". However, for many cities in Europe, this threshold has already been reached, as shown by the data gathered, analysed, and published by the European Data Journalism Network (EDJNet). The most affected cities are mainly found in Spain, in the Nordic countries, and in Romania. EDJNet analysed the data provided by the European Centre for Medium-term Weather Forecasts (ECMWF), which calculates meteorological data by combining inputs from various sources (meteorological stations, meteorological balloons, buoys, and satellite observations). The most affected cities

It is Time for Action on Climate Risk in the Balkans As countries in the Western Balkans continue to grow, so too does their exposure to risk from climate change and natural disasters. Over the last twenty years, living standards have increased six-fold in Bosnia and Herzegovina, nearly three-fold in Albania and in Serbia. More people are finding jobs and wages are rising. The region’s future, according to the latest World Bank projections, is bright. However, there are clouds gathering on the horizon. In 2014 we saw historic flooding that caused over €2 billion in damages and losses in Bosnia and Herzegovina (nearly 15 percent of the country’s gross domestic product) and over €1.5 billion in damages in losses in Serbia (nearly 5 percent of Serbia’s GDP). Linda Van Gelder Weather extremes like these are fast becoming the new normal – by the end of the century, in fact, average regional temperatures could rise by as much as 4 degrees Celsius or more above pre-industrial levels. This is simply too high a cost.
