1.What is bioenergy? Bioenergy is not ethanol.
什么是生物能源？生物能源不是乙醇。
2.Bioenergy isn’t global warming. Bioenergy is something which seems counterintuitive. Bioenergy is oil. It’s gas. It’s coal. And part of building
生物能源也不是全球变暖。生物能源 与很多人想象的东西不是一回事。生物能源 石油，是煤炭，是通向
3.that bridge to the future, to the point where we can actually see the oceans in a rational way, or put up these geo-spatial orbits that will twirl or
未来的桥梁的一部分。在那个彼岸，我们终于能够 理性地看待我们的海洋，或者 建立这些地理空间轨道，让它们能高速旋转或者
4.do microwaves or stuff, is going to depend on how we understand bioenergy and manage it. And to do that, you really have to look first at agriculture.
小幅度地波动，这些都将取决于 我们如何理解并管理好生物能源。要做到这些， 你必须首先了解农业。
5.So we’ve been planting stuff for 11,000 years. And in the measure that we plant stuff, what we learn from agriculture is you’ve got to deal with pests,
人类种植农作物的历史已经有11000年了。 在种植的过程中，我们学会了 如何对付害虫，
6.you’ve got to deal with all types of awful things, you’ve got to cultivate stuff. In the measure that you learn how to use water to cultivate, then
还要面对各种各样的麻烦， 培育出新的作物。了解到 如何用水来灌溉农田后，
7.you’re going to be able to spread beyond the Nile.
你还要能够把尼罗河水抽取上来。
8.You’re gonna be able to power stuff, so irrigation makes a difference.
你需要有动力设备，才能实现灌溉 产量就会大不相同。
9.Irrigation starts to make you be allowed to plant stuff where you want it, as opposed to where the rivers flood. You start getting this organic
灌溉使你能够随心所欲地种植农作物， 而不是只能种在 河水能够流到的地方。你可以开展这种有机农业，
10.agriculture, you start putting machinery onto this stuff. Machinery, with a whole bunch of water, leads to very large-scale agriculture.
你开始使用机械设备进行生产。 机械化，结合大量的水， 使大规模的农业生产成为可能。
11.You put together machines and water, and you get landscapes that look like this. And then you get sales that look like this. It’s brute force. So
运用机械及水，得到了 现在这样一幅图景。然后这样的一些 产品就能够销售出去。这是巨大外力的作用。
12.what you’ve been doing in agriculture is you start out with something that’s a reasonably natural system. You start taming that natural system. You
这样一个发展农业的过程，是从 一个原本相当自然的体系起步， 最终去驯服这个自然体系。
13.put a lot of force behind that natural system. You put a whole bunch of pesticides and herbicides — (Laughter) — behind that natural system, and you
你把很多外力施加于这个自然体系。 你使用了大量的杀虫剂和除草剂 （笑声）在这个自然系统中。
14.end up with systems that look like this.
你最终把这个系统改造成这个样子。
15.And it’s all brute force. And that’s the way we’ve been approaching energy. So the lesson in agriculture is that you can actually change the
这是在蛮干。这也是我们 取得能源的方式。应此 农业给我们带来的教训是，你可以
16.system that’s based on brute force as you start merging that system, and learning that system and actually applying biology. And you move from a
在使用大规模外力作用于一个体系的时候 融入这个体系，研究这个体系并将 生物学运用于其中。你从遵循
17.discipline of engineering, you move from a discipline of chemistry, into a discipline of biology. And probably one of the most important
机械的原理，运用化学的原理，转为 遵循生物学的原则。 这个世界上最重要的人之一，
18.human beings on the planet is this guy behind me.
就是我身后的这个人。
19.This is a guy called Norman Borlaug. He won the Nobel Prize. He’s got the Congressional Medal of Honor. He deserves all of this stuff. And he
他的名字叫Norman Borlaug。 他得到了诺贝尔奖。还获得了国会荣誉奖章。 这一切都是他应得的。
20.deserves this stuff because he probably has fed more people than any other human being alive because he researched how to put biology behind
因为他的贡献是让更多的人吃饱饭。 对此他做出的贡献比任何其他人都大。 他把生物学理论用于育种。
21.seeds. He did this in Mexico. The reason why India and China no longer have these massive famines is because Norman Borlaug taught them how to grow
他在墨西哥完成这项研究。这就是为什么 印度和中国不再有那么多人挨饿。 Norman Borlaug教他们如何用更高效的
22.grains in a more efficient way and launched the Green Revolution. That is something that a lot of people have criticized. But of course, those are
方法种植粮食作物，掀起一场 绿色革命。很多人对此 持批评的态度。当然，那是因为，那些人
23.people who don’t realize that China and India, instead of having huge amounts of starving people, are exporting grains.
没有意识到，中国和印度 不仅不再挨饿， 并且在出口粮食。
24.And the irony of this particular system is the place where he did the research, which was Mexico, didn’t adopt this technology, ignored this
具有讽刺意味的是，这个方法 在他进行这项研究的地方——墨西哥 这项技术没有得到应用，反而是被忽视。
25.technology, talked about why this technology should be thought about, but not really applied.
有人认为这项技术还有欠考虑的地方， 而没有真正去应用它。
26.And Mexico remains one of the largest grain importers on the planet because it doesn’t apply technology that was discovered in Mexico. And in
墨西哥仍旧是世界上最大的 谷物进口国，因为他们没有应用 在他们的国家发明的这项技术。
27.fact, hasn’t recognized this man, to the point where there aren’t statues of this man all over Mexico. There are in China and India. And the
事实上，他们并不认同这个人， 墨西哥没有这个人的塑像。 而在中国和印度都有。
28.institute that this guy ran has now moved to India. That is the difference between adopting technologies and discussing technologies.
这个人设立的研究机构现在搬到了 印度。这就是谈论一项技术和应用 这项技术二者之间的区别。
29.Now, it’s not just that this guy fed a huge amount of people in the world. It’s that this is the net effect in terms of what technology does, if you
现在，不仅仅是这个人的技术让世界上大量 的人有饭吃，而且，这示范了 科学技术所能起到的作用。如果
30.understand biology.
你懂得生物学的话。

31.What happened in agriculture? Well, if you take agriculture over a century, agriculture in about 1900 would have been recognizable to somebody
农业发生了怎样的变化？如果你回头看 一个世纪以前的农业， 1900年的农业跟一千年前的
32.planting a thousand years earlier. Yeah, the plows look different. The machines were tractors or stuff instead of mules, but the farmer would have
种植方法没有很大的区别。是的，看起来，犁的样子 有些不同。人们用上了拖拉机等机械 而不是骡子，但是农民们
33.understood, this is what the guy’s doing, this is why he’s doing it, this is where he’s going. What really started to change in agriculture is when
知道，这仍是人在操作， 他还是要这么做，没什么太大的不同。 农业真正开始改变
34.you started moving from this brute force engineering and chemistry into biology. And that’s where you get your productivity increases. And as
始自从使用大规模的 机械和化学力量转为运用生物学。并且 从此生产力大大提高了。
35.you do that stuff, here’s what happens to productivity.
自从你那么做以后，产量 这样的变化：
36.Basically, you go from 250 hours to produce 100 bushels, to 40, to 15, to five. Agricultural labor productivity increased seven times, 1950 to 2000,
基本上，产量从每250个小时生产100蒲式耳， 变为40、15，甚至5个小时就可以生产这么多。农业劳动力 的生产效率提高了7倍，从1950年到2000年间，
37.whereas the rest of the economy increased about 2.5 times. This is an absolutely massive increase in how much is produced per person.
其他的经济活动提高的程度是 2.5倍。这样的提高真是突飞猛进， 人均产出大大增加。
38.The effect of this, of course, is it’s not just amber waves of grain, it is mountains of stuff.
当然，这种效果，看上去 不仅是麦浪滚滚，而是堆积如山了。
39.And 50 percent of the EU budget is going to subsidize agriculture from mountains of stuff that people have overproduced.
结果是欧盟百分之五十的预算用于 对农业的补贴，补贴给人们生产出的这些粮食， 无疑已经是过度生产。
40.This would be a good outcome for energy. And of course, by now, you’re probably saying to yourself, “Self, I thought I came to a talk about
能源要是也有这样的局面就好了。 当然，听到这里，你也许会对自己说， “嘿，我想我是来听有关能源的演讲，
41.energy and here’s this guy talking about biology.”
可是这家伙在这里大谈生物。”
42.So where’s the link between these two things?
那么，这两个事物间的联系是什么呢？
43.One of the ironies of this whole system is we’re discussing what to do about a system that we don’t understand. We don’t even know what oil is. We
整个体系中具有讽刺意味的一点是， 我们在讨论对一个我们所不了解的体系要做点什么。 我们甚至都不知道石油到底是什么。
44.don’t know where oil comes from. I mean, literally, it’s still a source of debate what this black river of stuff is and where it comes
我们不知道石油是从哪里来的。 事实上，这至今都是有争议的， 这流动着的黑色物质到底是什么，是从哪里
45.from. The best assumption, and one of the best guesses in this stuff, is that this stuff comes out of this stuff. That these things absorb
来的。最靠谱的假说和猜测， 这种物质来自于这些东西。 这些东西吸收
46.sunlight, rot under pressure for millions of years, and you get these black rivers.
阳光，在压力的作用之下腐烂 经过了上百万年，变成了这黑色河流。
47.Now, the interesting thing about that thesis — if that thesis turns out to be true — is that oil, and all hydrocarbons, turned out to be
那么，这个理论有意思的地方在于， 如果这个理论是成立的，那么石油 以及所有的碳氢化合物，都是
48.concentrated sunlight. And if you think of bioenergy, bioenergy isn’t ethanol. Bioenergy is taking the sun, concentrating it in amoebas,
浓缩的阳光。如果你再来看 生物能源，生物能源不是乙醇，生物能源是 来自于太阳，（太阳的能量）浓缩在变形虫中，
49.concentrating it in plants, and maybe that’s why you get these rainbows.
浓缩在植物里，可能那就是 为什么有这些彩虹（一般的东西）。
50.And as you’re looking at this system, if hydrocarbons are concentrated sunlight, then bioenergy works in a different way. And we’ve got
你在审视这个体系的时候，如果 碳氢化合物是浓缩的阳光， 生物能源是以不同的方式起作用的。我们必须
51.to start thinking of oil and other hydrocarbons as part of these solar panels.
把石油和其他碳氢化合物看作是 太阳能板的一部分。
52.Maybe that’s one of the reasons why if you fly over west Texas, the types of wells that you’re beginning to see don’t look unlike those pictures
也许这就是其中的一个原因，当你飞过得克萨斯西部时， 看到那些油井的景象 似曾相识，
53.of Kansas and those irrigated plots.
它们与堪萨斯的灌溉图景大同小异。
54.This is how you farm oil. And as you think of farming oil and how oil has evolved, we started with this brute force approach. And then what did
这就是如何“收获”石油的景象。当你想象 石油可以这样收获以及它们是如何演化来的，我们开始 使用采用这种大规模外力的做法。然后，我们
55.we learn? Then we learned we had to go bigger. And then what’d we learn? Then we have to go even bigger. And we are getting really destructive as
学到了什么呢？我们学到了必须更大规模地干。 然后又学到什么呢？那就是还要干的 更大。我们变得破坏性越来越大，
56.we’re going out and farming this bioenergy.
在以这种方式收获生物能源的过程中。
57.These are the Athabasca tar sands, and there’s an enormous amount — first of mining, the largest trucks in the world are working here, and then
这是阿萨巴斯卡油砂田，油井 星罗棋布，第一步是开采， 世界上最大的卡车在这里工作。
58.you’ve got to pull out this black sludge, which is basically oil that doesn’t flow. It’s tied to the sand. And then you’ve got to use a lot of steam to
然后人们把这些黑色泥沙拉走， 这些黑泥基本上就是不流动的石油。 因为石油跟泥沙结合在一起了。下一步就要用
59.separate it, which only works at today’s oil prices.
大量的蒸气使它们分离，其成本之高 只有在现在的高油价下才有可能。
60.Coal. Coal turns out to be virtually the same stuff. It is probably plants, except that these have been burned and crushed under pressure.
煤炭事实上是差不多同样的 东西。其来源也是植物，不同之处在于 这些植物曾被焚烧，再被高压压碎。

61.So you take something like this, you burn it, you put it under pressure, and likely as not, you get this. Although, again, I stress: we don’t know.
你就用这一类东西，经过燃烧，把它们置于 压力之下，多半不会得到这样的 东西。尽管这样，我一再强调：我们并不知道真相。
62.Which is curious as we debate all this stuff. But as you think of coal, this is what burned wheat kernels look like. Not entirely unlike coal.
我们就这些事情进行辩论是出于好奇。 当你在考虑煤炭时，它们看起来跟燃烧过的 麦子很相似。这看起来跟煤炭没有太大差别。
63.And of course, coal mines are very dangerous places, because in some of these coal mines, you get gas. When that gas blows up, people die. So
当然，开采煤炭是非常危险的事情， 因为在一些煤矿里，你会 发现有毒气体。当这些气体爆炸时，是会死人的。
64.you’re producing a biogas out of coal in some mines, but not in others.
这些生物气体（比如沼气）存在于有些 煤矿，另外一些煤矿则没有。
65.Any place you see a differential, there’re some interesting questions. There’s some questions as to what you should be doing with this stuff. But
每个地方都有些不同之处，有些问题 很有意思。有的问题诸如 你应该如何对待这些东西。但是
66.again, coal. Maybe the same stuff, maybe the same system, maybe bioenergy, and you’re applying exactly the same technology.
仍以煤炭为例，它们可能是同样的东西，可能 是生成与同样的体系，可能就是生物能源，你都在运用 相同的技术。
67.Here’s your brute force approach. Once you get through your brute force approach, then you just rip off whole mountaintops. And you end up with
这就是施加大规模外力的方法。一旦你能够 成功地使用这种方法，结果是 整个山头被夷平。最终是
68.the single largest source of carbon emissions, which are coal-fired gas plants. That is probably not the best use of bioenergy.
造成最大单一来源的碳排放， 即燃煤燃气发电厂。这也许 并不是对生物能源的最好的利用。
69.As you think of what are the alternatives to this system — it’s important to find alternatives, because it turns out that the U.S. is dwindling in
当你试图发现还有什么更好的选择， 找到一种替代性的方法是很重要的， 因为人们意识到美国的
70.its petroleum reserves, but it is not dwindling in its coal reserves, nor is China. There are huge coal reserves that are sitting out there, and
石油储备在不断减少，但是 煤炭的储备并未减少，中国也是如此。 煤炭的储备量非常之大，
71.we’ve got to start thinking of them as biological energy, because if we keep treating them as chemical energy, or engineering energy, we’re
我们应该开始考虑把煤炭看作 生物能源，因为如果我们继续视其为 化学能源，或机械能源，我们
72.gonna be in deep doo-doo.
会陷入大麻烦。
73.Gas is a similar issue. Gas is also a biological product. And as you think of gas, well, you’re familiar with gas. And here’s a different way of
天然气也是类似的。天然气也是一种 生物产品。当你想到天然气时， 你会觉得很熟悉。开采天然气的方法

是不同于采煤的。
75.This is called coal bed methane. Why is this picture interesting? Because if coal turns out to be concentrated plant life, the reason why you may
这种气体称为煤层甲烷气。为什么 这个画面很有趣？因为如果煤炭真的是 浓缩的植物体，那么你在
76.get a differential in gas output between one mine and another — the reason why one mine may blow up and another one may not blow up — may be because
不同的煤矿发现有不同的气体 有的煤矿会爆炸 而有的又不会，可能都是因为
77.there’s stuff eating that stuff and producing gas.
有些东西吃掉了另一些东西而产生气体。
78.This is a well-known phenomenon. (Laughter) You eat certain things, you produce a lot of gas. It may turn out that biological processes in coal
这是一个广为人知的现象（大笑）。你 吃了某种东西后，会产生很多气体。 那可能也是在生物进程中煤矿中发生的
79.mines have the same process. If that is true, then one of the ways of getting the energy out of coal may not be to rip whole mountaintops off, and it
类似过程。如果这是真的， 那么从煤炭中获取能源的方法 就可以不必夷平整个山头，
80.may not be to burn coal. It may be to have stuff process that coal in a biological fashion as you did in agriculture.
也可能不必燃烧煤炭。也许可以对 煤炭进行某种生物处理，就像在 农业中所做的那样。
81.That is what bioenergy is. It is not ethanol. It is not subsidies to a few companies. It is not importing corn into Iowa because you’ve built so
这才是生物能源的含义。而不是什么乙醇。 并不是说要补贴几个公司，也不是 进口玉米到爱荷华州，去喂饱那些已经建起来的
82.many of these ethanol plants. It is beginning to understand the transition that occurred in agriculture, from brute force into biological
乙醇工厂。而是要开始 去理解发生在农业中的转变。 从大规模外力的模式转为使用生物力量。
83.force. And in the measure that you can do that, you can clean some stuff, and you can clean it pretty quickly.
在这么做的过程中， 你可以使很多东西变得清洁， 很快就可以做到。
84.We already have some indicators of productivity on this stuff. OK, if you put steam into coal fields or petroleum fields that have been running for

几十年，你可以获得明显的 增产，比如产量增加8倍。 这还只是最开始的

步骤。
87.And as you think of biomaterials, this guy — who did part of the sequencing of the human genome, who just doubled the databases of genes and
在你考虑生物材料时，这个人， 就是他完成了对人类基因组测序的一部分工作， 因为他的工作，基因和蛋白质数据库的数据量

105.And as you think about this stuff and what the implications of this are, we’re going to start not just converting ethanol from corn with very high
当你设想这个东西会给我们带来的 影响的时候，我们正在开始的一种转化， 不是那种享有很高的补贴的，将玉米转化为乙醇
106.subsidies. We’re going to start thinking about biology entering energy. It is very expensive to process this stuff, both in economic terms and in
的过程，我们正在开始考虑把 生物学用在能源方面。这种转化过程 代价很高，不论从经济的角度看，还是从
107.energy terms.
能源的角度来说。
108.This is what accumulates in the tar sands of Alberta. These are sulfur blocks. Because as you separate that petroleum from the sand, and use an
这是一种积聚在阿尔伯塔的油砂中的物质， 大堆大堆的硫磺。因为我们在从油砂中 分离石油的时候，要使用
109.enormous amount of energy inside that vapor — steam to separate this stuff — you also have to separate out the sulfur. The difference between
大量的能源进行蒸馏， 用蒸汽分离这些物质——你同时会分离出 硫磺来。轻质原油与重质原油的差别在于，
110.light crude and heavy crude — well, it’s about 14 bucks a barrel. That’s why you’re building these pyramids of sulfur blocks. And by the way, the
它们的价格每桶相差14美元。 这就是为什么你会看到这些堆的象金字塔 般的硫磺。并且，这些东西的
111.scale on these things is pretty large.
规模相当大。
112.Now, if you can take part of the energy content out of doing this, you reduce the system, and you really do start applying biological principles to
现在，如果你能够把做这部分工作消耗的能源 减少的话，你就简化了整个体系，并且 开始运用生物学原则于
113.energy. This has to be a bridge to the point where you can get to wind, to the point where you can get to solar, to the point where you can get to
能源的生产。这将是联系各种新能源的桥梁， 诸如风能的利用，太阳能的利用， 以及核能的利用，等等。
114.nuclear — and hopefully you won’t build the next nuclear plant on a beautiful seashore next to an earthquake fault. (Laughter) Just a thought.
希望你今后就不需要在风光秀美的海边， 在地震断层的附近建设新的核电厂。 （大笑）这还仅仅是个设想。
115.But in the meantime, for the next decade at least, the name of the game is hydrocarbons. And be that oil, be that gas, be that coal, this is what we’re
与此同时，至少在今后的几十年里， 唱主角的都是碳氢化合物。可以是 石油，可以是天然气，可以是煤炭，都是我们的
116.dealing with. And before I make this talk too long, here’s what’s happening in the current energy system.
研究对象。我不想把这个演讲拖得 太长，这里介绍一下目前的 能源体系的发展。
117.86 percent of the energy we consume are hydrocarbons. That means 86 percent of the stuff we’re consuming are probably processed plants and
我们消耗的能源的百分之八十六 是碳氢化合物。这意味着我们消耗物质的百分之八十六 是植物、变形虫和其他这类物质
118.amoebas and the rest of the stuff. And there’s a role in here for conservation. There’s a role in here for alternative stuff, but we’ve also got to
演化而来的。那么这里就有一个 环境保护的角色。还有一个 可替代物质的角色，同时我们必须
119.get that other portion right.
把其余的部分也做好。
120.How we deal with that other portion is our bridge to the future. And as we think of this bridge to the future, one of the things you should ponder
我们如何对待其余的那个比例是 我们通向未来的桥梁。当我们把这看作是通向未来的 桥梁时，有一件事必须认真思考：
121.is: we are leaving about two-thirds of the oil today inside those wells. So we’re spending an enormous amount of money and leaving most of the energy
现在我们把大约三分之二的石油留在 那些油井中。这样我们花费巨大的 开支，把大部分的能源留在
122.down there. Which, of course, requires more energy to go out and get energy. The ratios become idiotic by the time you get to ethanol. It may
地下。当然，这样做需要更多的能源 去获取其他能源。这个比值会变得 很愚蠢，如果你取得的是乙醇的话。
123.even be a one-to-one ratio on the energy input and the energy output. That is a stupid way of managing this system.
那样做，产出的能源与消耗的能源之比 几乎就是一比一。这是在用一种很傻的做法 管理这个体系。
124.Last point, last graph. One of the things that we’ve got to do is to stabilize oil prices. This is what oil prices look like. OK?
最后一点，最后一张图表，我们必须做的 事情之一是稳定石油价格。 这就是石油价格的走势，对不对？
125.This is a very bad system because what happens is your hurdle rate gets set very low. People come up with really smart ideas for solar panels, or for
这是一个很糟糕的体系，因为你的 最低资本预期回收率设置的很低。人们想出了 很好的太阳能板的设计，或者是利用
126.wind, or for something else, and then guess what?
风能或其他（新能源）的方式，猜猜会怎么样？
127.The oil price goes through the floor. That company goes out of business, and then you can bring the oil price back up.
石油价格跌破了最低点。那些公司 只好破产，然后石油价格又 重新上涨了。
128.So if I had one closing and modest suggestion, let’s set a stable oil price in Europe and the United States. How do you do that? Well, let’s put
因此，我最后要提出一个温和的建议， 让我们在欧洲和美国设定一个稳定的 石油价格。怎么能做到呢？那么，我们可以在
129.a tax on oil that is a non-revenue tax, and it basically says for the next 20 years, the price of oil will be — whatever you want, 35 bucks, 40
油价上加一项税——非收入税， 基本理念是说在最近的20年中，石油价格 将是——随便假设一个数字，35美元也好，
130.bucks. If the OPEC price falls below that, we tax it. If the OPEC price goes above that, the tax goes away.
40美元也罢。如果欧佩克的油价低于这个价格，我们 就开征这项税。如果油价高于这个价格，这项税 就取消。
131.What does that do for entrepreneurs? What does it do for companies? It tells people, if you can produce energy for less than 35 bucks a barrel, or
这样做对企业家有什么好处呢？对公司企业 有什么好处呢？这可以告诉人们，如果你能以 低于35美元或40美元的价格生产能源，
132.less than 40 bucks a barrel, or less than 50 bucks a barrel — let’s debate it — you will have a business. But let’s not put people through this
或低于50美元一桶的价格生产能源， 我们可以竞争——你就能赢得生意。 我们不能让人们进入这样
133.cycle where it doesn’t pay to research because your company will go out of business as OPEC drives alternatives and keeps bioenergy from
一种循环，（由于油价的波动）企业付不出研发费用 而破产，这就等于让欧佩克操纵了石油替代品的研发 使生物能源无法取得成功。
