推荐理由
Skip to 6 minutes in the video for when he starts showing compiled data of when its better to buy a new car vs keep old.
说明
这是2021年由Engineering Explained发布的一部讲解，主题归在Cars, EVs & motorcycles。它讲的是car lifecycle emissions这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：Engineering Explained compares the lifecycle emissions of keeping an old car with those of buying a new, more efficient one. It weighs manufacturing emissions against emissions from driving, and covers gas versus electric cars.这些读者给出的理由，核心是：HN commenters cite it in EV and emissions debates for its numbers on when replacing a car pays off.讲法不绑某一条新闻，过几年仍然可以当材料看。从2021年到2025年，有2位不同的读者在2个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比，比背公式重要。如果已经会了基本定义，就把注意力放在它怎么把car lifecycle emissions变成能跟着复述的例子。
