    Ono tak pro porovnani neni dulezite pri jakem tlaku se to skladuje, ale pri kterem se udava ta jednotka. Zajimala by me vyhrevnost 1m3 vtom clanku abych mohl porovnat ty spotrby.

    RAGNAROK: LPG je asi pod 10x mensim tlakem, CNG by na 200 atmosfer

    "Spotreba auta na CNG v m3 a na benzin v litrech se zhruba rovna"

    Nevim nekde pisou 1 m3 CNG =1 dm3benzinu.
    zalezi pri jakem tlaku se udava 1 m3 CNG. Jak je to doopravdy by me zajimalo. Kdysi sme meli auto na LPG dokud nam ho neukradli tak sezkusim zeptat.

    MESK: no v Thajsku jiny autobusy nez diesely predelany na CNG nejezdej. :-) A videls v Praze autobusy "Jezdim na Zemni Plyn"? :-)

    E2E4: tudiz, prejde-li treba polovina dopravy na CNG - predelat diesel je moc drahy a nerentabilni - vydrzi evropske zasoby mene nez 30 let. Predpokladam, ze doprava spotrebuje daleko vic energie nez ostatni spotreba.

    E2E4:
    A to jako kdyz vsichni prejdou na CNG tak to taky vydrzi 60 let? Nebo je to odhad z BAU kdy na CNG jezdi 1%?

    BIDAK: jojo, CNG je hodně.. :) holt když dochází konvenční, přejdeme na nekonvenční, a když je nekonvenční ropa obtížně získatelná, tak na plyn.. Peak Oil se stane Peak LOL. :))

    Jinak v Barmě (jedna z nejchudších zemí na světě) předělávají na CNG i ta jejich 20+ let stará auta..

    E2E4: Zajímavý. Takže si nakonec mám koupit auto na CNG, hm.

    The peak oil crisis: peak oil elasticity
    http://www.postcarbon.org/article/325600-the-peak-oil-crisis-peak-oil

    In the years prior to the recession that began in roughly 2008 US summer demand for gasoline was about 9.6 million b/d and slowly increasing. For the last two summers however, demand has peaked at about 9.3 million b/d suggesting that the recession has cut about 300,000 b/d off peak driving season demand. Some of this drop in demand, of course, is from business. With the economy limping along on the federal stimulus spending and housing construction way below the highs of five years ago, the use of gasoline is down. High gasoline prices and widespread un/under-employment have forced many to reduce gasoline consumption. Anecdotal evidence suggests that driving by the large numbers of unemployed teenagers is way below what it once was. In short, the weaker hands cut their gasoline consumption over the last few years. The average U.S. personal vehicle (cars, trucks and SUVs) consumes about 700 gallons of fuel a year. At $4 a gallon this is now about $2800 a year to fuel the average passenger vehicle. Each dollar a gallon increase adds only $60 a month to the gasoline bill, an amount manageable by many given the “essential” of personal transport.

    This analysis suggests that at least for the immediate future we are not likely to see much of a drop in the demand for gasoline. If the economy slows further, then commercial demand for fuels by industry, business, airlines, etc. is likely to drop. Detroit is already expressing concern that $4.50 gasoline will cut into sales of large vehicles much as $4 gasoline did three years ago. For most there is currently no ready substitute for gasoline. When it comes to food, chicken or pasta can readily be substituted for beef, and restaurants bypassed. But for the mobility which is essential to our lifestyles few have an acceptable ready substitute. While U.S. gasoline consumption may fall by hundreds of thousands of barrels due to higher prices in the next few years, it is difficult to foresee it falling by millions.
