盖茨称赞特斯拉汽车很棒!但离“零排放”还有距。.据Teslarati报道,微软联合创始人、慈善家比尔·盖茨(Bill Gates)最近接受YouTube技术评论员马克斯·布朗利(Marques Brownlee)专访,谈到他对特斯拉等电动汽车以及交通领域碳排放的看法。在简短的专访中,盖茨称赞特斯拉的电动汽车很棒。但他也承认,要使交通变得更加环保,还有许多工作要做。


盖茨称赞特斯拉汽车很棒!但离“零排放”还有距离


盖茨对特斯拉汽车并不陌生。早在2016年,他就被拍到与科幻小说《七夏娃》(Seveneves)的作者尼尔·斯蒂芬森(Neal Stephenson)共同驾驶特斯拉Model X的场景。盖茨在最近的采访中提到了这家总部位于硅谷的电动汽车制造商,称特斯拉的汽车“令人惊叹”,同时表示该公司仍有很长的路要走。盖茨还指出,购车者不久将有更多电动汽车可供选择。

盖茨说:“特斯拉电动汽车堪称是令人惊叹的产品,当前非常流行,但它仍然只占相当小的市场份额。这是一款高价汽车,而且没有了联邦政府的7500美元税收抵免优惠,因此这让特斯拉的处境变得更加艰难。现在,大批汽车制造商正加入进来,部分是因为加州施行的零排放政策,部分是因为电动汽车已经成为流行趋势。很快,将有许多更好的电动汽车可供选择。”

不过,盖茨补充说,在电网完全摆脱化石燃料之前,电动汽车无法实现零排放目标。

盖茨表示:“乘用车所需的电力输出比卡车低。所以,即使卡车最终也使用电池供电,其面临的挑战也更困难,因为卡车的重量要比乘用车高得多。而对于电动乘用车来说,它们仍然是碳排放的源头,因为它使用的电力间接需要排放碳。因此,只有在把电动汽车比例提高到相当高的水平,才能得到零排放的电力来源,这样乘用车的碳排放才能说接近于零。”

尽管盖茨对电动汽车的担忧有其正当理由,但应该指出的是,电动汽车比燃烧化石燃料的汽车更环保,即使用来为它们充电的电力主要来自煤炭发电。彭博社最近的一项研究强调了这一点,该研究得出结论认为,电池驱动的汽车二氧化碳排放量比内燃机汽车低40%,即使是在那些依赖煤炭的地区也是如此。

盖茨似乎也低估了特斯拉等公司在电池技术方面取得的进展。过去一年,埃隆·马斯克(Elon Musk)暗示,特斯拉已经接近每千瓦时电池组成本100美元的目标,这将帮助该公司的电动汽车实现与汽油动力汽车驾驶成本持平。特斯拉的电池技术也取得了进展,该公司即将推出的全电动半挂卡车Semi的续航里程已接近960公里。电池技术的改进如此引人注目,甚至连尼古拉汽车(Nikola Motor)这样的公司也决定推出电池驱动的卡车。

盖茨在接受采访时称,他似乎还需要一段时间才能完全接受这样的理念,即电池动力汽车将成为世界向可持续能源过渡的潜在催化剂。考虑到特斯拉多年来取得的进步,盖茨完全接受电动汽车可能只是个时间问题。
