So, let&#39s just take a closer look at nuclear.所以，让我们好好研究一下核能。The United Nations Intergovernmental Panel on Climate Change has looked at the carbon content of all these different fuels,联合国气候变化政府间协商组织调查了不同燃料的碳含量，and nuclear comes out really low -- it&#39s actually lower even than solar.结果表明：核能有比太阳能还

So what about the other reactors? There&#39s a reactor that&#39s coming online now, they&#39re starting to sell it.换作反应堆呢？现在有一款即将完成的反应堆，它即将开始售卖。It&#39s a high-temperature gas reactor. It can&#39t melt down.这是一个高温气体反应堆。它不会融化。But it&#39s really big and bulky, that&#39s part of the safety,但是为了安全性考虑，它的体

And what about the waste? Everyone worries about the waste.那来自核能的废物呢？每个人都在担心废料。Well, the interesting thing about the waste is how little of it there is. This is just from one plant.但是有趣的是，产生的废物其实只有一点儿。这就是由一个核电站产生的废料。If you take all the nuclear waste we&#39ve ever made in the United States,如果你把美国核电站产

We did a report: &quotHow to Make Nuclear Cheap.&quot我们做了一个报告：《如何降低核能价格》。In particular, the thorium reactor shows a lot of promise.具体来说，钍反应堆带来了光明的前景。So when the climate scientist, James Hansen,所以当环境科学家詹姆斯·汉森asked if I wanted to go to China with him and look at the Chinese advanced nuclear program, I

So when we went through the numbers, and just added that up当我们查看这些数据的时候，把它们加起来，how much nuclear do we see China and India bringing online over the next 15 years,未来15年内，中国和印度会建多少核电站呢？how much do we see at risk of being taken offline -- this was the most startling finding.又有多少面临被报废的风险呢？答案令人震惊。What we

Let&#39s take a closer look in the United States.让我们来看看美国。Over the last couple of years -- really 2013, 2014 -- we prematurely retired four nuclear power plants.在过去的几年里，尤其是2013、14年，我们过早报废了四个核电站。They were almost entirely replaced with fossil fuels,它们的发电量几乎全部被化石燃料发电取代了，and so the consequence was that

That&#39s why when, in California, we try to deal with all the solar we&#39ve brought online这就是为什么在加州，我们正在尝试太阳能的完全使用，we now get about 10 percent of electricity from solar我们现在能够从太阳能获得大约10%的电力，when the sun goes down, and people come home from work and turn on their air conditioners and their TV sets,当

Have you heard the news? We&#39re in a clean energy revolution. And where I live in Berkeley, California,你们看新闻了吗？我们正在进行清洁能源革命。我住在加利福尼亚州伯克利市，it seems like every day I see a new roof with new solar panels going up, electric car in the driveway.几乎每天我都会看到新的太阳能板被装在屋顶上，电动汽车停在车道上。Germany sometimes gets hal

Now, you might wonder, &quotCome on, how much could five percentage points of global electricity be?&quot现在你可能会问，“拜托，全球5%的电力能有多少？”Well, it turns out to be quite a bit.事实证明还蛮多的。It&#39s the equivalent of 60 nuclear plants the size of Diablo Canyon, California&#39s last nuclear plant,这些电力等价于60个核电站的产量，每

As I was leaving China, the engineer that brought Bill Gates there kind of pulled me aside, and he said,当我离开中国的时候，那个请来比尔·盖茨的工程师曾把我拉到一边，然后他说，&quotYou know, Michael, I appreciate your interest in all the different nuclear supply technologies,“你知道吗，迈克尔，我很欣赏你能对不同核电技术感兴趣。but there&#39s this more basic is
