The IEA has updated estimates since 2009, but the overall trends are the same. We hope that with the implementation of demand-side efficiency measures worldwide, long-range estimates will prove to be overestimated. According to the US Department of Energy (Energy Information Administration), the world consumption of energy in all of its forms (barrels of petroleum, cubic meters of natural gas, watts of hydro power, etc.) is projected to reach 678 quadrillion Btu (or 715 exajoules) by 2030 – a 44% increase over 2008 levels (levels for 1980 were 283 quadrillion Btu and we stand at around 500 quadrillion Btu today in 2009). I wonder what surface area would be required and what type of infrastructural investment would be required to supply that amount of power by using only solar panels. So to find this out we start with the big number 678,000,000,000,000,000 Btu.
Psykt og folkelig | STUDVEST.no «How I met my therapist» er underholdende og energisk hele veien, men skjemmes noe av mangel på originalitet og rød tråd. I utgangspunktet har de gjort det lett for seg ved å ha et konsept som kan inneholde alt: En mor i fremtiden forteller sine barn om hvordan det var å leve og være student i Bergen i 2012. Revyen beveger seg hovedsaklig innenfor dette triangelet: Psykologistudenten, Bergen og medier. Åpningsnummeret, i musikalstil, er eksplosivt og omhandler den forvirrende følelsen man kan få av å være ny student i Bergen. Revyen skrider videre med artige og gjenkjennelige sketsjer i et høyt tempo, om studentøkonomi, kollektivtilværelse iscenesatt som et realityshow og lesesalsproblemer. Det høye tempoet er en kvalitet, og noen av de korteste sketsjene er faktisk blant de mest originale og gode. Skuespillerne gjør en god jobb, og de er flinke til å parodiere kjente folk på en treffende måte.
Fossil fuels Fuels such as coal, oil and natural gas were formed over millions of years from organic matter like plankton, plants and other life forms. Over time, sand, sediment and rock buried the organic matter and it eventually formed large quantities of fuels. These underground resources, known as fossil fuels, are still the primary fuel source for electricity, heating and powering vehicles around the globe. Five main fossil fuels Coal is a combustible black or brown organic sedimentary rock. It’s mostly carbon and is typically found as layers (coal beds) or veins (coal seams). Natural gas is a combustible mix of hydrocarbon gases. Oil is mostly known as crude oil or condensate, but includes all liquid hydrocarbon fossil fuels. Petroleum is a liquid fuel made of hydrocarbons and other liquid organic compounds. Liquefied petroleum gas or LPG is heavier than natural gas.

Climate Change comic I intend to come back to this strip and rewrite some of the first half, in order to make the science clearer. I'm sure there will be a few spelling errors and suchlike. Feel free to point them out, but keep in mind that I've been staring at many of these pages for weeks, to the point where even the word 'and' looks funny to me. I shall be adding on references to this strip over the coming few days. Thanks to Albert the Knowledge Penguin for his help. Note: added Jan 2012. A few references. Superb New Yorker piece about the Koch Brothers and their involvement with the far right. That Proceedings of the National Academy of Science paper, which I mention in the strip, on the numbers of climate researchers who believe that science points to the truth of man made climate change, compared to those researchers who don't. Excellent book that does what it says on the tin. NASA's climate change evidence page. Scott Mandia's research into the media's deplorable Climategate coverage.
Electricity for kids - and everyone else: A simple introduction! Advertisement by Chris Woodford. Last updated: April 14, 2016. If you've ever sat watching a thunderstorm, with mighty lightning bolts darting down from the sky, you'll have some idea of the power of electricity. A bolt of lightning is a sudden, massive surge of electricity between the sky and the ground beneath. The energy in a single lightning bolt is enough to light 100 powerful lamps for a whole day or to make a couple of hundred thousand slices of toast! Electricity is the most versatile energy source that we have; it is also one of the newest: homes and businesses have been using it for not much more than a hundred years. What is electricity? Electricity is a type of energy that can build up in one place or flow from one place to another. Static electricity Static electricity often happens when you rub things together. Have you ever walked across a nylon rug or carpet and felt a slight tingling sensation? Lightning is also caused by static electricity. How static electricity works
Kunsten å si nei : Ny Tid PRISET: Jarle Bernhoft fikk denne uka én million kroner fra Statoil. Han må dermed stille opp for oljeselskapet flere ganger. Avtalen innebærer gjensidig respekt, opplyser Statoils informasjonssjef. Foto: wikicommons 18. februar mottok Jarle Bernhoft (35) Statoil-stipendet på én million kroner fra oljeselskapets informasjonsdirektør. 23.02.2012 17:28 – Av Torbjørn Tumyr Nilsen torbjorn@nytid.no Pris. Brando er borte i protest. Francis Ford Coppolas Gudfaren gir Brando en Oscar-statuett han ikke ønsker motta. SA NEI I: Sacheen Littlefeather sa 27. mars 1973 nei til Oscar-statuetten, på vegne av Marlon Brando. Og i Brandos sted går den 26 år gamle apache-kvinnen Sacheen Littlefeather opp på podiet, ikledd tradisjonelle apacheklær. En sjokkert verden ser på i vantro. Marlon Brandos Oscar-avslag blir historisk, og det får følger for hvordan Hollywood framstilte og behandlet urfolk. Bylarm-splittelsen Henne eller Statoil-stipendnominasjonen. Vi møter henne på en helt annen café i hovedstaden.
Fossil Fuels Fossil fuels: Energy from fossilised organic materials Custom Search How it works: Coal is crushed to a fine dust and burnt. Oil and gas can be burnt directly. The main bit to remember: More: More details on 'clean coal technology' from BBC News web site... Other fossil fuels are being investigated, such as bituminous sands and oil shale. As far as we know, there is still a lot of oil in the ground. Find out more at www.eia.doe.gov/emeu/cabs/canada.html Disadvantages Basically, the main drawback of fossil fuels is pollution.
Norway’s Greatest Vulnerability Is Also Its Greatest Strength The unspeakable horror of this weekend’s massacre in Norway is exaggerated exponentially by terrorist Anders Breivik’s abuse of one of civil society’s most distinctive features: the trust that the public places in law enforcement. And Norway may be particularly vulnerable to such a breach, as a country with a particularly deep faith in its the integrity of its institutions. Norway’s best civil qualities, in this case, also made it most vulnerable to the worst impulses of this killer. Like its fellow Scandinavian countries, Norway is near the top of the world’s charts in many enviable ways: high standard of living and productivity, high levels of happiness, impressive longevity, low levels of economic inequality and corruption and in general, extremely low levels of violent and other crimes. Countries with this profile tend to have the highest levels of trust in their fellow citizens and institutions. PHOTOS: Anders Behring Breivik, the Extremist Behind Norway’s Tragedy
Welcome! | Oresome Resources - Minerals and Energy Education Islamofobi og antisemittisme - tvillingideologier I denne artikkelen vil jeg vise hvordan den ideverdenen som selverklært kalles ”islamkritikk” sammenfaller med antisemittismens ideverden. Men først vil jeg grunngi hvorfor det å sammenstille disse ideene ikke bare er legitimt men også nødvendig. Aldri mer Holocaust Etter 2. Verdenskrig lovte alle verdens stater at den formen for menneskelig grusomhet som utspilte seg gjennom Holocaust aldri mer skulle kunne gjentas. De aller fleste elever kjenner både begrepet Holocaust og hovedtrekkene i hvordan dette artet seg i form av konsentrasjonsleire, gasskamre og forbrenningsovner. Empati og moralsk avstandtakelse er nødvendig men ikke tilstrekkelig som politisk vaksinering mot nye Holocaust. Forståelsen av hvorfor jødehatet kunne blomstre så sterkt i store deler av Europa i denne tida er også svært begrensa. Nå er jeg heller ikke av den oppfatninga at slik detaljkunnskap bør forutsettes fra elevene når de går ut av ungdomsskolen. Fra religionskritikk til rasisme Overtakelse av Europa
