舊車換新 油需大跌?

上個禮拜,有個讀者寄電郵畀孫柏文問:「美國政府動用30億美元去推舊車換新計劃,會否令石油需求減少,繼而令油價下跌?」

正式嚟講,個計劃係想達致減少用油,減少花旗國依賴進口石油嘅目標。之前我喺公仔箱都有從多角度講過花旗國舊車換新計劃,不過就真係計漏咗究竟會用少幾多油,今日補番。

依家啲估計,如果行駛里數等不變(ceteris paribus)每架新車比舊車每年會慳大約280加侖油,即大約1060公升。如果以特區13.5港元零售價計,慳萬四蚊。

日慳萬四桶油成效存疑

因平均每架新車有4000美元補貼,30億美元補貼就會有75萬架新車,即係每年總共慳2.1億加侖。

一桶石油有42加侖,即啲新車總共每年慳大約500萬桶石油,即每日用少13700桶。

每日13700桶多定少?全球每日用超過8000萬桶油,淨係花旗國都2000萬。

而花旗國嗰2000萬中,大約950 萬桶係用嚟開車。950萬比13700,相信大家都知成效有幾多。

今時今日,每5個喺花旗國有駕駛執照嘅人,就有6架車,花旗政府仲走去補貼買新車,真係典型凱因斯主義嘅政策。即係完全違反常智,不過有如王帝的新衣,「聰明人」先睇到點解要咁做。

今次真係要挺下啲反對分子,大家知唔知邊啲人最反對呢個計劃?就係啲踩單車嘅花旗國人。

  1. I think you miss a point that
    Crude oil cannot be 100% change to car used oil.
    Which have many light oil use in Airplane, some other heavy oil. use for road and ship.

  2. Anon,

    That was the world before cracking was invented.

    With high enough prices. All oil can be made into Octane for cars.

    But! I agree with Michael Moore on this, one day human will look back and be shocked by us BURNING oil for fuel... because plastic is so useful.

    Kinda like us looking back 100 years at people back then hunting whale for lighting.
