电动车充电效率与可持续能源

字幕原文

So, 那么，

in effect, even if you take transmission into account 实际上，即使你把输电损耗也考虑进去，

and everything, even using the same source fuel, you're at least twice 甚至所有一切都考虑进去，即使使用相同的燃料来源，你给电动汽车充电，也至少比在发

as better off charging an electric car than burning it at the power 电厂燃烧燃料划算两

plant. 倍。

That scale delivers efficiency. 这种规模带来了效率。

Yes, 是的，

it does. 确实如此。

And then the other point is we have to have sustainable means of 另外一点是，我们无论如何都需要可持续的

power generation anyway, electricity generation. 发电方式，也就是电力生产。

So given that we have to solve sustainable electricity generation, 既然我们必须解决可持续电力生产的问题，

then 那么，

it makes sense for us to have electric cars 我们拥有电动汽车就很有意义了，

as the mode of transport. 作为交通方式。

So we've got some video here of 所以我们这里有一些关于

the Tesla being assembled, 特斯拉组装的视频，

which if you could play 如果你能播放

that first video. 第一个视频。

So what is innovative about this process in this vehicle? 那么，这个过程和这辆车有什么创新之处呢？

Sure. 当然。

So 那么，

in order to accelerate the advent of electric transport, 为了加速电动交通的到来，

and I should say that I think 我应该说，我认为

actually 实际上，

all modes of transport will become fully electric, with the ironic exception of 除了一个讽刺的例外，所有交通方式都将完全电动化，

rockets. 那就是火箭。

So there's just no way around Newton's third law. 所以牛顿第三定律是无法规避的。

The question is, how do you accelerate the advent of electric transport? 问题是，你如何加速电动交通的到来呢？

And in order to do 而为了做到

that for cars, you have to come up with a really 这一点，对于汽车来说，你必须设计出一款真正

energy efficient car. 节能的汽车。

So that means making it incredibly light. 所以这意味着要让它极其轻巧。

And so what you're seeing here is the only all-aluminum 所以你在这里看到的是唯一一款全铝

body and chassis car made in North America. 车身和底盘的北美制造汽车。
