America's public energy conversation
0
225
2262
美国的公众能源的讨论
00:18
boils down to this question:
1
2487
2223
可以归结为这个问题
00:20
Would you rather die of A) oil wars,
2
4710
3380
你比较倾向于哪种死法：A)石油战争
00:23
or B) climate change,
3
8090
2610
B) 气候变化
00:26
or C) nuclear holocaust,
4
10700
1400
C) 核战浩劫
00:28
or D) all of the above?
5
12100
3300
D) 以上所有
00:31
Oh, I missed one: or E) none of the above?
6
15400
2800
哦，我还忘了一个 E) 以上都不要?
00:34
That's the one we're not normally offered.
7
18200
2115
正常情况下没有这个选项
00:36
What if we could make energy do our work
8
20315
2139
如果我们可以利用能源，帮助我们工作
00:38
without working our undoing?
9
22454
2446
而又不会招致灭亡，将有多好?
00:40
Could we have fuel without fear?
10
24900
2100
我们能不能安心地使用燃料?
00:42
Could we reinvent fire?
11
27000
2408
我们能不能重燃火源(Reinvent fire是艾默里·罗文斯的关于能源运用方式改造的新书)?
00:45
You see, fire made us human;
12
29408
1630
大家知道，用火造就了人类
00:46
fossil fuels made us modern.
13
31038
2054
化石燃料引领我们变得现代化
00:48
But now we need a new fire
14
33092
1300
但现在我们需要一种新的火
00:50
that makes us safe, secure, healthy and durable.
15
34392
3523
一种能让我们安全，有保障，健康而且可持续的火
00:53
Let's see how.
16
37915
2259
让我们来看看要怎么做
00:56
Four-fifths of the world's energy
17
40174
2886
世界能源的五分之四
00:58
still comes from burning each year
18
43060
1773
仍然来自于每年燃烧
01:00
four cubic miles of the rotted remains
19
44833
3500
四平方英里原始沼泽
01:04
of primeval swamp goo.
20
48333
2600
遗留的腐化物质
01:06
Those fossil fuels
21
50933
2134
化石燃料
01:08
have built our civilization.
22
53067
3077
造就了我们的文明
01:12
They've created our wealth.
23
56144
2069
创造了我们的财富
01:14
They've enriched the lives of billions.
24
58229
1576
丰富了数十亿人的生活
01:15
But they also have rising costs
25
59805
2639
但它们也在导致
01:18
to our security, economy, health and environment
26
62444
4389
我们安全、经济、健康和环境的成本上升
01:22
that are starting to erode, if not outweigh their benefits.
27
66833
3254
这些成本正逐渐侵蚀效益，虽然现在仍可能是利大于弊
01:25
So we need a new fire.
28
70087
2242
所以我们需要一种新的火
01:28
And switching from the old fire to the new fire
29
72329
2902
从旧的火转换为新的火
01:31
means changing two big stories about oil and electricity,
30
75231
4036
意味着两大改变：石油与电力
01:35
each of which puts two-fifths of the fossil carbon in the air.
31
79267
4677
它们都会向空气排放五分之二的化石碳
01:39
But they're really quite distinct.
32
83944
1969
但两者间显著差别
01:41
Less than one percent of our electricity is made from oil --
33
85913
3412
只有不到1%的电力来自于石油能源
01:45
although almost half is made from coal.
34
89325
3704
而将近一半的电力来自于燃煤
01:48
Their uses are quite concentrated.
35
93029
2279
两者用途又都非常集中
01:51
Three-fourths of our oil fuel is transportation.
36
95308
2740
四分之三的石油被用于交通运输
01:53
Three-fourths of our electricity powers buildings.
37
98048
2775
四分之三的电力被用于建筑物供电
01:56
And the rest of both runs factories.
38
100823
2041
两者的剩下部分被用于工厂运作
01:58
So very efficient vehicles, buildings and factories
39
102864
3836
因此高效的车辆，建筑物与工厂
02:02
save oil and coal,
40
106700
1769
可以节省石油和煤
02:04
and also natural gas that can displace both of them.
41
108469
3431
也能省下可以替代石油和煤的天然气
02:07
But today's energy system is not just inefficient,
42
111900
3685
但是当今的能源系统不仅效率低下
02:11
it is also disconnected,
43
115585
2007
而且零散
02:13
aging, dirty and insecure.
44
117592
2708
老旧，肮脏，还不安全
02:16
So it needs refurbishment.
45
120300
2477
因此能源系统需要改头换面
02:18
By 2050 though, it could become efficient,
46
122777
3428
到2050年，它会变得更有效率
02:22
connected and distributed
47
126205
3262
更具系统，被妥善运用
02:25
with elegantly frugal
48
129467
1400
因为简约节能的
02:26
autos, factories and buildings
49
130867
2733
汽车、工厂以及建筑物
02:29
all relying on a modern, secure
50
133600
2367
都依赖于现代、安全
02:31
and resilient electricity system.
51
135967
2662
并且灵活的电力系统
02:34
We can eliminate our addiction to oil and coal by 2050
52
138629
5438
到2050年，我们将不再依赖石油和煤
02:39
and use one-third less natural gas
53
144067
3169
并减少三分之一的天然气使用量
02:43
while switching to efficient use
54
147236
2885
与此同时我们将有效地使用能源
02:46
and renewable supply.
55
150121
2584
与可再生资源
02:48
This could cost, by 2050,
56
152705
3533
到2050年，这一切开销
02:52
five trillion dollars less in net present value,
57
156238
3252
将比现在净价值少5万亿美元
02:55
that is expressed as a lump sum today,
58
159490
2643
这里是指总价
02:58
than business as usual --
59
162133
1546
是与照常营运相比——
02:59
assuming that carbon emissions
60
163679
1454
假设碳排放
03:01
and all other hidden or external costs are worth zero --
61
165133
3065
以及所有其他隐性或外部成本为零
03:04
a conservatively low estimate.
62
168198
3884
这只是保守的估计
03:07
Yet this cheaper energy system
63
172082
1951
但是这个更低耗的能源系统
03:09
could support 158 percent bigger U.S. economy
64
174033
3834
能够支持相当于现量158%的美国经济
03:13
all without needing oil or coal,
65
177867
2369
完全不需要石油或煤
03:16
or for that matter nuclear energy.
66
180236
2464
或是核能
03:18
Moreover, this transition needs no new inventions
67
182700
3023
此外，这个转变不需要新发明
03:21
and no acts of Congress
68
185723
3262
也不需要国会的法令
03:24
and no new federal taxes, mandate subsidies or laws
69
188985
4482
不需要新的联邦税种，强制补助或立法
03:29
and running Washington gridlock.
70
193467
2951
或是使美国政府陷入困境
03:32
Let me say that again.
71
196418
915
让我重申一次
03:33
I'm going to tell you how to get the United States
72
197333
2769
我将告诉你怎样让美国
03:36
completely off oil and coal, five trillion dollars cheaper
73
200102
3311
完全摆脱石油或煤，减少5万亿美元的开销
03:39
with no act of Congress
74
203413
1346
而且不需要
03:40
led by business for profit.
75
204759
2510
以盈利组织为主导的国会制订新法
03:43
In other words, we're going to use our most effective institutions --
76
207269
3639
换句话说，我们将利用我们最有效的组织 民营企业
03:46
private enterprise co-evolving with civil society
77
210908
3813
与公民社会共同进步
03:50
and sped by military innovation
78
214721
2512
并通过军队改革，来加速这一进程
03:53
to go around our least effective institutions.
79
217233
2800
这样才能绕过最低效的机构
03:55
And whether you care most
80
220033
2334
不论你最关心的是
03:58
about profits and jobs and competitive advantage
81
222367
3431
利润、工作和竞争优势
04:01
or national security, or environmental stewardship
82
225798
2410
还是国家安全、环境管理
04:04
and climate protection and public health,
83
228208
2161
还是气候保护和公众健康
04:06
reinventing fire makes sense and makes money.
84
230369
4283
重新发明能源使用方式，合理也有赚头
04:10
General Eisenhower reputedly said
85
234652
3446
据说艾森豪威尔将军曾说过
04:13
that enlarging the boundaries of a tough problem
86
238098
2620
扩大一个难题的范围
04:16
makes it soluble by encompassing more options and more synergies.
87
240718
4569
就能涵盖更多的选择和协同作用，从而解决问题
04:21
So in reinventing fire,
88
245287
1669
因此在重新发明能源使用方式时
04:22
we integrated all four sectors that use energy --
89
246956
3167
我们整合耗能的全部四个领域——
04:26
transportation, buildings, industry and electricity --
90
250123
3639
交通，建筑，工业与电力——
04:29
and we integrated four kinds of innovation,
91
253762
2623
也整合了四种创新
04:32
not just technology and policy,
92
256385
2548
不只是科技与政策
04:34
but also design and business strategy.
93
258933
3100
也包括设计和商业策略
04:37
Those combinations yield
94
262033
2015
这些组合产生的效益
04:39
very much more than the sum of the parts,
95
264048
2106
远高于各项的总和
04:42
especially in creating deeply disruptive business opportunities.
96
266154
5346
特别是合并后，将创造颠覆性的商业机遇
04:47
Oil costs our economy two billion dollars a day,
97
271500
4048
石油每天花去我们20亿美元
04:51
plus another four billion dollars a day
98
275548
2367
再加上另外的
04:53
in hidden economic and military costs,
99
277915
2647
隐性经济与军费开支花去的40亿美元
04:56
raising its total cost to over a sixth of GDP.
100
280562
3930
石油总消费超过GDP(国内生产总值)的六分之一
05:00
Our mobility fuel goes three-fifths to automobiles.
101
284492
2544
既然用于交通工具的燃料的五分之三都花在汽车上
05:02
So let's start by making autos oil free.
102
287036
2646
让我们从汽车免费用油开始着手
05:05
Two-thirds of the energy it takes to move a typical car
103
289682
3180
驱动一辆普通汽车所需能源的三分之二
05:08
is caused by its weight.
104
292862
2202
是由车子的重量贡献的
05:10
And every unit of energy you save at the wheels,
105
295064
3507
通过减轻车子重量或减少制动阻力
05:14
by taking out weight or drag,
106
298571
1247
在这上面每节约的一单位能量
05:15
saves seven units in the tank,
107
299818
2030
就能节约油箱中七单位的能量
05:17
because you don't have to waste six units
108
301848
1685
因为你已不需要多浪费六单位能源
05:19
getting the energy to the wheels.
109
303533
2100
将能量传输到车轮上
05:21
Unfortunately, over the past quarter century,
110
305633
3585
但不幸的是，在过去的25年中
05:25
epidemic obesity has made our two-ton steel cars
111
309218
2715
肥胖问题的流行，让我们2吨的钢制车变得更重
05:27
gain weight twice as fast as we have.
112
311933
3823
而且增加的速度是以前的两倍
05:31
But today, ultralight, ultrastrong materials,
113
315756
3654
但在当今，超轻、超强度的材料
05:35
like carbon fiber composites,
114
319410
2569
比如碳纤维复合材料
05:37
can make dramatic weight savings snowball
115
321995
2372
能让显著减轻车子重量
05:40
and can make cars simpler and cheaper to build.
116
324367
3915
并使汽车的制造变得更简单，价格更便宜
05:44
Lighter and more slippery autos
117
328282
2366
车子越轻，开动阻力越小
05:46
need less force to move them,
118
330648
2247
驱动所需的动力就越少
05:48
so their engines get smaller.
119
332895
2274
引擎就能越小
05:51
Indeed, that sort of vehicle fitness
120
335169
2831
实际上，车辆的这种轻便性
05:53
then makes electric propulsion affordable
121
338000
3167
使得电力驱力变得实惠
05:57
because the batteries or fuel cells
122
341167
3133
因为电力电池或燃料电池
06:00
also get smaller and lighter and cheaper.
123
344300
3600
也会变得更小、更轻、更便宜
06:03
So sticker prices will ultimately fall to about the same as today,
124
347900
3900
所以汽车的定价最终将回落到目前定价相近水平
06:07
while the driving cost, even from the start,
125
351800
3521
而驾驶成本，甚至是从一开始开始算起
06:11
is very much lower.
126
355321
1748
也低了很多
06:12
So these innovations together can transform automakers
127
357069
4146
所以说这些创新组合在一起，就能让汽车制造商
06:17
from wringing tiny savings
128
361215
2362
使他们从在维多利亚时代的引擎与邮票印章技术上
06:19
out of Victorian engine and seal-stamping technologies
129
363577
3331
钻营微小的节约
06:22
to the steeply falling costs
130
366908
2738
转到由三项紧密联系相互强化的创新
06:25
of three linked innovations that strongly reenforce each other --
131
369646
5100
带来的成本的巨幅下降——
06:30
namely ultralight materials, making them into structures
132
374746
3923
也就是说运用超轻的材料，将它们用于建设
06:34
and electric propulsion.
133
378669
2331
与电力驱动系统
06:36
The sales can grow and the prices fall even faster
134
381000
4700
通过实行短期的退税方案
06:41
with temporary feebates,
135
385700
1708
就能增加销量，更快地降低价格
06:43
that is rebates for efficient new autos
136
387408
2254
这种退税方，是针对高效能的新型汽车的退款
06:45
paid for by fees on inefficient ones.
137
389662
3100
并由低效汽车的生产商给付
06:48
And just in the first two years
138
392762
2846
而仅仅在最初的两年内
06:51
the biggest of Europe's five feebate programs
139
395608
3448
欧洲五个费用退还计划中最大的一个
06:54
has tripled the speed of improving automotive efficiency.
140
399056
4046
就将汽车能源效率改进的速度提高了三倍
06:59
The resulting shift to electric autos
141
403102
3429
由此带来的向电动汽车的转变
07:02
is going to be as game-changing
142
406531
1471
将像由打字机向使用电脑的转变
07:03
as shifting from typewriters to the gains in computers.
143
408002
4198
一样改变游戏规则
07:08
Of course, computers and electronics
144
412200
2100
不必多言，电脑与电子产品
07:10
are now America's biggest industry,
145
414300
2300
是当今美国最大的产业
07:12
while typewriter makers have vanished.
146
416600
2154
打字机制造商却已消失得无影无踪
07:14
So vehicle fitness
147
418754
1921
因此交通工具的轻便性
07:16
opens a new automotive competitive strategy
148
420675
3569
启动了新型汽车业竞争战略
07:20
that can double the oil savings over the next 40 years,
149
424244
3254
一种能够使未来40年内汽车省油率翻倍
07:23
but then also make electrification affordable,
150
427498
2877
同时让电动车变得平价
07:26
and that displaces the rest of the oil.
151
430375
3984
还能让电动车取代汽油车的战略
07:30
America could lead this next automotive revolution.
152
434359
3556
美国能够引领下一轮汽车业革命
07:33
Currently the leader is Germany.
153
437915
2485
当前起主导作用的是德国
07:36
Last year, Volkswagen announced
154
440400
2508
去年，大众汽车宣布
07:38
that by next year they'll be producing
155
442908
2223
今天他们将生产出
07:41
this carbon fiber plugin hybrid
156
445131
2869
具备碳纤维插件的混合动力车
07:43
getting 230 miles a gallon.
157
448000
2408
行驶230英里耗油1加仑(约合100公里/升)
07:46
Also last year, BMW announced
158
450408
2515
同样在去年，宝马公司宣布生产
07:48
this carbon fiber electric car,
159
452923
2269
这种碳纤维电动车
07:51
they said that its carbon fiber is paid for
160
455192
1975
他们宣称使用碳纤维的成本
07:53
by needing fewer batteries.
161
457167
2054
可以由相应减少的电池需求来平衡
07:55
And they said, "We do not intend to be a typewriter maker."
162
459221
2531
他们还说，“我们不想成为打字机制造商。”
07:57
Audi claimed it's going to beat them both by a year.
163
461767
3508
奥迪公司宣称将用一年时间击败这两个对手
08:01
Seven years ago, an even faster and cheaper
164
465275
3225
7年前，一种更快更低价的
08:04
American manufacturing technology
165
468500
2592
美国式制造技术
08:06
was used to make this little carbon fiber test part,
166
471092
7444
被用于制造这个小小的碳纤维试用零件
08:14
which doubles as a carbon cap.
167
478536
2339
使得碳排放上限翻了一番
08:16
(Laughter)
168
480875
1563
(笑声)
08:18
In one minute -- and you can tell from the sound
169
482438
3062
在一分钟之内——你就能从听出
08:21
how immensely stiff and strong it is.
170
485500
2833
它有多么坚硬牢固
08:24
Don't worry about dropping it, it's tougher than titanium.
171
488333
3492
它掉到地上也没事，因为它比钛还要坚硬
08:27
Tom Friedman actually whacked it as hard as he could with a sledgehammer
172
491825
2223
汤姆弗里德曼曾拿大锤用尽全力敲它
08:29
without even scuffing it.
173
494048
1539
它却毫发无损
08:31
But such manufacturing techniques
174
495587
2115
但这样的制造技术
08:33
can scale to automotive speed and cost
175
497702
3223
如果能结合流体设计
08:36
with aerospace performance.
176
500925
1454
就能影响汽车的速度和成本
08:38
They can save four-fifths of the capital needed to make autos.
177
502379
3521
它们能节省五分之四的汽车制造成本
08:41
They can save lives
178
505900
1162
它们能保障生命安全
08:42
because this stuff can absorb
179
507062
1292
因为它能吸收的撞击力
08:44
up to 12 times as much crash energy per pound as steel.
180
508354
3264
是每磅钢铁所能吸收的碰撞能(撞击产生的能量)的12倍
08:47
If we made all of our autos this way,
181
511618
1749
如果我们用这种方法制造所有的汽车
08:49
it would save oil equivalent to finding
182
513367
2923
省下的石油相当于
08:52
one and a half Saudi Arabias, or half an OPEC,
183
516290
2832
找到一个半的沙特阿拉伯，或者半个OPEC(石油输出国家组织)
08:55
by drilling in the Detroit formation, a very prospective play.
184
519122
4432
如果从底特律钻井开始着手，就很有可能成功
08:59
And all those mega-barrels under Detroit
185
523554
2700
而所有那些底特律地下的蕴含的巨大油桶
09:02
cost an average of 18 bucks a barrel.
186
526254
2513
每桶都要18美元
09:04
They are all-American, carbon-free
187
528767
1846
它们全为美国生产，属于无碳排放
09:06
and inexhaustible.
188
530613
2320
取之不尽，用之不竭
09:08
The same physics and the same business logic
189
532933
2754
同样的道理，同样的商业逻辑
09:11
also apply to big vehicles.
190
535687
1546
也适用于大型车辆
09:13
In the five years ending with 2010,
191
537233
2692
2005到2010年
09:15
Walmart saved 60 percent of the fuel per ton-mile
192
539925
4575
沃尔玛的大批重型卡车队
09:20
in its giant fleet of heavy trucks
193
544500
1400
减少了60%的每英里耗油量
09:21
through better logistics and design.
194
545900
1400
这归功于它们较好的物流和规划
09:23
But just the technological savings in heavy trucks
195
547300
3015
但仅在重型卡车技术上的节约
09:26
can get to two-thirds.
196
550315
1885
就占了三分之二
09:28
And combined with triple to quintuple efficiency airplanes,
197
552200
3287
如果我们结合三到五倍能源效率的飞机
09:31
now on the drawing board,
198
555487
1721
正在被设计的飞机
09:33
can save close to a trillion dollars.
199
557208
2246
就省下接近一万亿美元
09:35
Also today's military revolution in energy efficiency
200
559454
4369
如今军队在能源效率上的改革
09:39
is going to speed up all of these civilian advances
201
563823
2977
也将促进所有这些民用的技术的发展
09:42
in much the same way that military R&D
202
566800
2529
就像是军方研发
09:45
has given us the Internet, the Global Positioning System
203
569329
3194
给我们带来互联网、全球定位系统
09:48
and the jet engine and microchip industries.
204
572523
3069
喷气机引擎和微芯片产业
09:51
As we design and build vehicles better,
205
575592
3523
随着我们设计、制造更好的汽车
09:55
we can also use them smarter
206
579115
2100
我们也能更聪明地使用它们
09:57
by harnessing four powerful techniques
207
581215
2247
通过运用联合四种强力的技术
09:59
for eliminating needless driving.
208
583462
1992
来减少驾驶时无谓的损耗
10:01
Instead of just seeing the travel grow,
209
585454
2792
与其只看到出游时里程的增长
10:04
we can use innovative pricing,
210
588246
2654
我们还能用创新的定价方式
10:06
charging for road infrastructure by the mile, not by the gallon.
211
590900
3954
按英里数给道路基建收费，而不是耗油量
10:10
We can use some smart IT to enhance transit
212
594854
3246
我们可以用一些巧妙的IT技术来优化这个过程
10:14
and enable car sharing and ride sharing.
213
598100
3541
让拼车变得可行
10:17
We can allow smart and lucrative growth models
214
601641
4259
我们可以用聪明且有利可图的增长模型
10:21
that help people already be near where they want to be,
215
605900
4177
来帮助已经接近目标的人们
10:25
so they don't need to go somewhere else.
216
610077
1513
这样他们就不会走上歧路
10:27
And we can use smart IT
217
611590
2110
而且我们可以用智慧的IT技术
10:29
to make traffic free-flowing.
218
613700
2536
保持交通顺畅
10:32
Together, those things can give us the same or better access
219
616252
2815
所有这些结合起来，能让我们更接近目标
10:34
with 46 to 84 percent less driving,
220
619067
4500
省下46-84%的驾驶消耗
10:39
saving another 0.4 trillion dollars,
221
623567
2638
4千亿美元的开销
10:42
plus 0.3 trillion dollars from using trucks more productively.
222
626205
4995
还有3亿美元，是通过有效使用卡车省下的成本
10:47
So 40 years hence, when you add it all up,
223
631200
2705
把所有金额相加，我们将看到40年后
10:49
a far more mobile U.S. economy
224
633905
3008
一个更灵动的美国汽车经济
10:52
can use no oil.
225
636913
2079
将完全摆脱石油
10:54
Saving or displacing barrels for 25 bucks
226
638992
3508
每桶油能省下25美元
10:58
rather than buying them for over a hundred,
227
642500
1400
而不再花去一百多元钱
10:59
adds up to a $4 trillion net saving
228
643900
3775
忽略隐性成本的话
11:03
counting all the hidden costs at zero.
229
647675
3007
净节约额将达到四万亿美元
11:06
So to get mobility without oil,
230
650682
2918
所以为了让交通业摆脱对石油的依赖
11:09
to phase out the oil,
231
653600
2100
终结交通的石油时代
11:11
we can get efficient and then switch fuels.
232
655700
3431
我们需要增加效率，并改变能耗方式
11:15
Those 125 to 240 mile-per-gallon-equivalent autos
233
659131
4344
那些耗油量为每加仑125到240英里的汽车
11:19
can use any mixture of hydrogen fuel cells,
234
663475
3843
可以混合使用氢燃料电池
11:23
electricity and advanced biofuels.
235
667318
3111
电力电池和先进的生物燃料
11:26
The trucks and planes can realistically use
236
670429
3653
卡车和飞机实际上可以用
11:29
hydrogen or advanced biofuels.
237
674082
2820
氢燃料或生物燃料
11:32
The trucks could even use natural gas.
238
676902
2065
卡车甚至可以用天然气
11:34
But no vehicles will need oil.
239
678967
2000
所有的交通工具都将摆脱对石油的依赖
11:36
And the most biofuel we might need,
240
680967
3085
而我们所需的
11:39
just three million barrels a day,
241
684052
1743
每天不会超过三百万桶的生物燃料
11:41
can be made two-thirds from waste
242
685795
1638
三分之二来自废物回收处理
11:43
without displacing any cropland
243
687433
1834
它们不需要占用农田
11:45
and without harming soil or climate.
244
689267
3033
对土壤和气候也无害
11:48
Our team speeds up these kinds of oil savings
245
692300
2015
我们的团队正在加速推行这些省油模式
11:50
by what we call "institutional acupuncture."
246
694315
2952
我们叫它“体制针灸”
11:53
We figure out where the business logic
247
697267
1400
我们找到那些商业逻辑
11:54
is congested and not flowing properly,
248
698667
2469
拥堵不畅的地方
11:57
we stick little needles in it to get it flowing,
249
701136
1812
在这些地方插入细针帮助疏通
11:58
working with partners like Ford and Walmart and the Pentagon.
250
702948
2493
我们和福特汽车、沃尔玛和五角大楼等都有合作
12:01
And the long transition is already well under way.
251
705441
3461
长期的转换过程已经开始
12:04
In fact, three years ago mainstream analysts were starting to see peak oil,
252
708902
4303
事实上，三年前，主流分析师已经注意到
12:09
not in supply, but in demand.
253
713205
2947
石油峰值，不在供应面，而将在需求面出现
12:12
And Deutsche Bank even said world oil use could peak around 2016.
254
716152
5112
德意志银行甚至宣称全球石油使用量将在2016年达到顶峰
12:17
In other words, oil is getting uncompetitive even at low prices
255
721264
4661
换句话说，在石油还没有贵到买不起时
12:21
before it becomes unavailable even at high prices.
256
725925
4093
它已经使去竞争力了
12:25
But the electrified vehicles
257
730018
2926
但是电动汽车
12:28
don't need to burden the electricity grid.
258
732944
2777
并不会对电网造成负担
12:31
Rather, when smart autos exchange electricity and information
259
735721
3435
当这些新型汽车通过装配有智能电网的建筑物
12:35
through smart buildings with smart grids,
260
739156
2426
来交换电力和资讯时
12:37
they're adding to the grid valuable flexibility and storage
261
741582
3316
它们为电网增加了宝贵的弹性和存储能力
12:40
that help the grid integrate
262
744898
1850
从而帮助电网整合运用
12:42
varying solar and wind power.
263
746748
2847
不断变化的太阳能和风能
12:45
So the electrified autos
264
749595
1676
所以这些电动汽车
12:47
make the auto and electricity problems
265
751271
2624
整合并解决了交通和电力的问题
12:49
easier to solve together than separately.
266
753895
2238
这样比分别处理更容易
12:52
And they also converge the oil story
267
756133
1831
电动汽车还整合了
12:53
with our second big story,
268
757964
2584
石油和电力的使用模式
12:56
saving electricity and then making it differently.
269
760548
3760
节省电力，并使它全面改观
13:00
And those twin revolutions in electricity
270
764308
2982
再生能源和电动汽车的改革
13:03
will bring to that sector
271
767290
3054
为电力系统带来的改造
13:06
more numerous and profound and diverse disruptions
272
770344
2785
比它们对其它系统带来的影响
13:09
than any other sector,
273
773129
1361
更多，更深远，更广泛
13:10
because we've got 21st century technology and speed colliding head-on
274
774490
4215
其原因在于，我们所拥有的二十一世纪的技术
13:14
with 20th and 19th century institutions, rules and cultures.
275
778705
4695
和前两个世纪的制度、规章和文化格格不入
13:19
Changing how we make electricity gets easier
276
783400
3075
如果我们对电力的需求量降低了
13:22
if we need less of it.
277
786475
2515
改变用电方式，也将变得简单
13:24
Most of it now is wasted
278
788990
1662
现在大部分的电力是被浪费掉了
13:26
and the technologies for saving it
279
790652
1981
而节电技术的发展越来越快
13:28
keep improving faster than we're installing them.
280
792633
2954
甚至超过了我们启用它们的速度
13:31
So the unbought efficiency resource
281
795587
2446
所以还未被使用的高效资源
13:33
keeps getting ever bigger and cheaper.
282
798033
2900
变得越来越多，越来越便宜
13:36
But as efficiency in buildings and industry
283
800933
3062
但是随着建筑物和工业的用电效率
13:39
starts to grow faster than the economy,
284
803995
1972
提高得越来越快，超过经济增长速度
13:41
America's electricity use could actually shrink,
285
805967
4423
美国实际上会降低电力消耗
13:46
even with the little extra use required
286
810390
3597
尽管高效的电动汽车
13:49
for those efficient electrified autos.
287
813987
1980
会带来一小部分额外的耗电
13:51
And we can do this just by reasonably accelerating existing trends.
288
815967
4828
我们只要适当地推进当前进程，就可以达到这一步
13:56
Over the next 40 years, buildings,
289
820795
2338
四十年后
13:59
which use three-quarters of the electricity,
290
823133
2208
消耗四分之三总电能的建筑物
14:01
can triple or quadruple their energy productivity,
291
825341
3834
会将能源生产力提高三到四倍
14:05
saving 1.4 trillion dollars, net present value,
292
829175
3925
省下1.4万亿美元的净现值
14:09
with a 33 percent internal rate of return
293
833100
3600
还有33%的内部收益率
14:12
or in English,
294
836700
1671
换句话说
14:14
the savings are worth four times what they cost.
295
838371
3196
省下来的部分相当于成本的四倍
14:17
And industry can accelerate too,
296
841567
2238
工业也将加速发展
14:19
doubling its energy productivity
297
843805
1716
它的能源生产力将提高两倍
14:21
with a 21 percent internal rate of return.
298
845521
2948
还有21%的内部收益率
14:24
The key is a disruptive innovation
299
848469
2039
关键就在于颠覆性创新
14:26
that we call integrative design
300
850508
2823
我们叫它整合设计
14:29
that often makes very big energy savings
301
853331
2928
它通常能够带来巨大的节约
14:32
cost less than small or no savings.
302
856259
2477
而耗费的成本很小，甚至为零
14:34
That is, it can give you expanding returns,
303
858736
2628
也就是说，它将带来递增的报酬
14:37
not diminishing returns.
304
861364
1854
而非递减的报酬
14:39
That is how our 2010 retrofit
305
863218
3746
沿着这个思路，我们在2010年
14:42
is saving over two-fifths of the energy in the Empire State Building --
306
866964
3203
把帝国大厦的6500扇窗户
14:46
remanufacturing those six and a half thousand windows on site
307
870167
4154
换成透光、反射热能的超级玻璃
14:50
into super windows that pass light, but reflect heat.
308
874321
4312
由此省下帝国大厦超过五分之二能耗
14:54
plus better lights and office equipment and such
309
878633
3185
配合更好的照明和办公设备
14:57
cut the maximum cooling load by a third.
310
881818
3615
这项举动使冷却系统的最大负荷量减少了三分之一
15:01
And then renovating smaller chillers instead of adding bigger ones
311
885433
5067
我们翻新小型冷却机，而不添置大型冷却机
15:06
saved 17 million dollars of
312
890500
1523
这也省下了1700万的资本成本
15:07
capital cost, which helped pay for the other improvements
313
892023
3377
节省下来的成本得以被用于改进其它部门
15:11
and reduce the payback to just three years.
314
895400
4044
同时，投资回收期被减少到三年
15:15
Integrative design can also increase
315
899444
2223
整合设计也可以帮助
15:17
energy savings in industry.
316
901667
2208
工业节约能源
15:19
Dow's billion-dollar efficiency investment
317
903875
1992
道琼斯指数的十亿美元提高能率的投资
15:21
has already returned nine billion dollars.
318
905867
3300
已经得到了九十亿美元的回报
15:25
But industry as a whole has another half-trillion dollars
319
909167
2946
但是工业作为一个整体
15:28
of energy still to save.
320
912113
2195
还需要省下五千亿美元的能源
15:30
For example, three-fifths of the world's electricity runs motors.
321
914308
4559
比如说，世界上五分之三的电力被用于驱动马达
15:34
Half of that runs pumps and fans.
322
918867
2069
其中的一半被用在泵和风扇上
15:36
And those can all be made more efficient,
323
920936
2874
它们都可以变得更有效率
15:39
and the motors that turn them
324
923810
1715
通过整合35个改造项目
15:41
can have their system efficiency roughly doubled
325
925525
3650
就可以使它们的驱动马达，系统效率提高两倍
15:45
by integrating 35 improvements, paying back in about a year.
326
929175
3915
而且投资回收期仅为一年
15:48
But first we ought to be capturing bigger, cheaper savings
327
933090
3228
但是我们首先必须省下那些更大宗的、更便宜的
15:52
that are normally ignored and are not in the textbooks.
328
936318
2649
经常被忽略，连教科书也不提及的节能项目
15:54
For example, pumps, the biggest use of motors,
329
938967
3154
比如说，泵，使用发动机能量最多的一部分
15:58
move liquid through pipes.
330
942121
1817
推动液体通过管道
15:59
But a standard industrial pumping loop
331
943938
1800
但是标准的工业抽水循环
16:01
was redesigned to use at least 86 percent less energy,
332
945738
4377
经过重新设计，可以省下至少86%的能量
16:06
not by getting better pumps,
333
950115
1939
不需要添置新泵
16:07
but just by replacing long, thin, crooked pipes
334
952054
3382
只需把细薄的弯管
16:11
with fat, short, straight pipes.
335
955436
2616
换成粗短的直管
16:13
This is not about new technology,
336
958052
3215
这并不是使用新技术
16:17
it's just rearranging our metal furniture.
337
961267
1977
只是重新安排金属设备
16:19
Of course, it also shrinks the pumping equipment
338
963244
2354
当然，这减少了泵的使用量
16:21
and its capital costs.
339
965598
1715
也减少了资本成本
16:23
So what do such savings mean
340
967313
2620
那么，这对于被马达耗去五分之三能源的电力来说
16:25
for the electricity that is three-fifths used in motors?
341
969933
3682
意味着什么？
16:29
Well, from the coal burned at the power plant
342
973615
3100
从燃烧煤炭的发电厂
16:32
through all these compounding losses,
343
976715
3121
到所有这些化合物耗损
16:35
only a tenth of the fuel energy
344
979836
2823
只有十分之一的化石能源
16:38
actually ends up coming out the pipe as flow.
345
982659
3000
最后通过管道供给终端使用
16:41
But now let's turn those compounding losses around backwards,
346
985659
3674
现在让我们逆转化合物耗损的趋势
16:45
and every unit of flow or friction that we save in the pipe
347
989333
5631
在管道中省下的每一单位能量
16:50
saves 10 units of fuel cost, pollution
348
994964
4144
就能省下十个单位的燃料成本、污染
16:55
and what Hunter Lovins calls "global weirding"
349
999108
2607
和亨特·罗文斯所说的“全球气候异常”
16:57
back at the power plant.
350
1001731
1402
能量最终能回归到发电厂
16:59
And of course, as you go back upstream,
351
1003133
1692
当然，如果回溯到上游工业
17:00
the components get smaller and therefore cheaper.
352
1004825
3300
化合物会更小，也会更便宜
17:04
Our team has lately found such snowballing energy savings
353
1008125
4580
我们的团队最近发现这样滚雪球式的节能方式
17:08
in more than 30 billion dollars worth of industrial redesigns --
354
1012705
3233
可以被运用在超过300亿的工业重新设计中——
17:11
everything from data centers and chip fabs
355
1015938
2729
从数据中心，到芯片制造
17:14
to mines and refineries.
356
1018667
2192
到矿井和炼油厂，都适用
17:16
Typically our retrofit designs
357
1020859
1441
尤其是我们的改进设计
17:18
save about 30 to 60 percent of the energy
358
1022300
2954
可以省下30-60%的能源
17:21
and pay back in a few years,
359
1025254
1946
几年内就能得到投资回报
17:23
while the new facility designs save 40 to 90-odd percent
360
1027200
4154
设计新设备也将省下四成到九成多的能源
17:27
with generally lower capital cost.
361
1031369
2431
一般也能降低资本成本
17:29
Now needing less electricity
362
1033800
3064
减少对电力的需求
17:32
would ease and speed
363
1036864
2315
就可以让向新能源，也就是再生能源的转换
17:35
the shift to new sources of electricity, chiefly renewables.
364
1039179
3162
变得更容易一些，更快一些
17:38
China leads their explosive growth and their plummeting cost.
365
1042341
4484
中国在这方面发展迅猛，成本也暴跌
17:42
In fact, these solar power module costs
366
1046825
3421
实际上，这些太阳能发电板的成本
17:46
have just fallen off the bottom of the chart.
367
1050246
2379
已经低得不能再低了
17:48
And Germany now has more solar workers
368
1052625
3070
在德国，从事太阳能产业的人员数量
17:51
than America has steel workers.
369
1055695
2638
和美国从事钢铁业的人一样多
17:54
Already in about 20 states
370
1058333
1846
大致在20个州里
17:56
private installers will come
371
1060179
2354
已经有私营厂商
17:58
put those cheap solar cells on your roof with no money down
372
1062533
3485
可以把便宜的太阳能板安装在你家屋顶上，还能免费拆除
18:01
and beat your utility bill.
373
1066018
1869
轻松省下大笔水电费
18:03
Such unregulated products
374
1067887
2192
这些未经调控的产业
18:05
could ultimately add up to a virtual utility
375
1070079
2854
最终可以成为一种虚拟公共事业
18:08
that bypasses your electric company
376
1072933
2954
能越过电力公司
18:11
just as your cellphone bypassed your wireline phone company.
377
1075887
3831
就像你可以越过家里的有线电话公司，使用手机
18:15
And this sort of thing gives utility executives the heebee-jeebees
378
1079718
3418
它会让公共事业工作人员烦躁不已
18:19
and it gives venture capitalists sweet dreams.
379
1083136
2223
它还是风险投资家的美梦
18:21
Renewables are no longer a fringe activity.
380
1085359
3093
可再生能源不再是一个锦上添花的产业
18:24
For each of the past four years
381
1088452
2477
在过去四年间的每一年
18:26
half of the world's new generating capacity
382
1090929
2838
全世界发电量的一半
18:29
has been renewable,
383
1093767
1597
是可再生能源
18:31
mainly lately in developing countries.
384
1095364
1692
近年来主要分布在发展中国家
18:32
In 2010, renewables other than big hydro,
385
1097056
4292
在2010年，除了水力、风力和太阳能以外的
18:37
particularly wind and solar cells,
386
1101348
2331
可再生能源
18:39
got 151 billion dollars of private investment,
387
1103679
4992
接受了高达1510亿的私人投资
18:44
and they actually surpassed the total installed capacity
388
1108671
2585
它们实际上已经超过了
18:47
of nuclear power in the world
389
1111256
1685
全球核电站装机容量的总和
18:48
by adding 60 billion watts in that one year.
390
1112941
3459
每年产量比核电站多600亿瓦特
18:52
That happens to be the same amount of solar cell capacity
391
1116400
3700
太阳能电板装机容量也是如此
18:56
that the world can now make every year --
392
1120100
2815
全世界每年产量
18:58
a number that goes up 60 or 70 percent a year.
393
1122915
3347
可以增加60-70%
19:02
In contrast, the net additions of nuclear capacity and coal capacity
394
1126262
5533
相反地，核电站、燃煤电厂和其它项目的净增量
19:07
and the orders behind those keep fading
395
1131795
3569
在不断减少
19:11
because they cost too much and they have too much financial risk.
396
1135364
2536
因为它们成本太高，带来的金融风险也高
19:13
In fact in this country,
397
1137900
1400
事实上在美国
19:15
no new nuclear power plant
398
1139300
2115
已经没有新的核电站
19:17
has been able to raise any private construction capital,
399
1141415
2518
可以吸引来自私人的建设投资
19:19
despite seven years of 100-plus percent subsidies.
400
1143933
4415
尽管在七年间，政府每年都投入翻倍的补助款
19:24
So how else could we replace the coal-fired power plants?
401
1148348
4004
所以，我们还可以用什么来取代这些燃煤电厂呢?
19:28
Well efficiency and gas can displace them all
402
1152352
3769
高效的发电方式和天然气可以完全取代燃煤
19:32
at just below their operating cost
403
1156121
2684
成本比燃煤的运作成本还低
19:34
and, combined with renewables, can displace them more than 23 times
404
1158805
3754
如果和可再生能源结合起来，还可以取代燃煤方式23次
19:38
at less than their replacement cost.
405
1162559
2074
所耗费用还不及它们的重置成本
19:40
But we only need to replace them once.
406
1164633
2008
但只需要取代一次就够了
19:42
We're often told though
407
1166641
2688
常常有人对我们说
19:45
that only coal and nuclear plants can keep the lights on,
408
1169329
2381
只有燃煤和核能才能稳定供电
19:47
because they're 24/7,
409
1171710
1285
因为它们是全天候的
19:48
whereas wind and solar power are variable,
410
1172995
2823
而风能和太阳能变幻多端
19:51
and hence supposedly unreliable.
411
1175818
3015
所以有人认为它们不可靠
19:54
Actually no generator is 24/7. They all break.
412
1178833
3385
实际上没有发电机全天候工作，它们也需要休息
19:58
And when a big plant goes down,
413
1182218
2115
当一个发电厂停止运转
20:00
you lose a thousand megawatts in milliseconds,
414
1184333
2792
每毫秒就会损失一千兆瓦的发电力
20:03
often for weeks or months, often without warning.
415
1187125
3493
一旦发生，就常常是几周几个月，而且毫无征兆
20:06
That is exactly why we've designed the grid
416
1190618
1997
这就是我们为什么要设计出电网
20:08
to back up failed plants with working plants.
417
1192615
4270
用正常工作的电站来顶替暂停运转的电站
20:12
And in exactly the same way,
418
1196885
1730
同样地
20:14
the grid can handle wind and solar power's
419
1198615
5031
电网可以克服风能和太阳能的
20:19
forecastable variations.
420
1203646
2549
可预测的变化
20:22
Hourly simulations
421
1206195
3307
每小时的模拟显示
20:25
show that largely or wholly renewable grids
422
1209502
3767
大部分或全部的可再生能源电网
20:29
can deliver highly reliable power
423
1213269
1777
可以输送非常稳定的电力
20:30
when they're forecasted,
424
1215046
1629
只要对风能和太阳能
20:32
integrated and diversified
425
1216675
2054
根据种类和位置
20:34
by both type and location.
426
1218729
2053
进行预测、整合和多元化处理
20:36
And that's true both for continental areas like the U.S. or Europe
427
1220782
4223
这对美国或欧洲这样的大陆地区
20:40
and for smaller areas embedded within a larger grid.
428
1225005
4485
和被大型电网覆盖的较小地区都适用
20:45
That is how, for example,
429
1229490
1639
这就是，比如说
20:47
four German states in 2010
430
1231129
2384
在2010年，德国的四个州
20:49
were 43 to 52 percent wind powered.
431
1233513
2597
实现由风力供应43-52%能源的做法
20:52
Portugal was 45 percent renewable powered,
432
1236125
3642
葡萄牙实现了45%能源由风能供应
20:55
Denmark 36.
433
1239767
2325
而丹麦是36%
20:57
And it's how all of Europe can shift
434
1242092
3285
这就是全欧洲国家
21:01
to renewable electricity.
435
1245377
1285
向可再生能源转型的做法
21:02
In America, our aging, dirty and insecure power system
436
1246662
4725
在美国，我们老化、肮脏、不可靠的能源系统
21:07
has to be replaced anyway by 2050.
437
1251387
2884
不论如何都需要在2050年前被取代
21:10
And whatever we replace it with
438
1254271
1627
而且不论我们用什么来取代它
21:11
is going to cost about the same,
439
1255898
1438
花费都会和现在差不多
21:13
about six trillion dollars at present value --
440
1257336
2710
大约六万亿美元的净现值——
21:15
whether we buy more of what we've got
441
1260046
2208
不论我们会不会购买更多的现有资源
21:18
or new nuclear and so-called clean coal,
442
1262254
2113
建现多的核电厂，使用所谓的洁净煤技术
21:20
or renewables that are more or less centralized.
443
1264367
3631
或是现在或多或少已经被集中处理的可再生能源
21:23
But those four futures at the same cost
444
1267998
3269
但是这四种未来的选择成本相近
21:27
differ profoundly in their risks,
445
1271267
2069
风险却很不一样
21:29
around national security,
446
1273336
2531
不论是事关国家安全
21:31
fuel, water, finance, technology,
447
1275867
3538
燃料，水，金融，技术，气候和健康
21:35
climate and health.
448
1279405
1531
风险都有显著差别
21:36
For example, our over-centralized grid
449
1280936
2835
比如说，过于集中化的电网
21:39
is very vulnerable to cascading
450
1283771
3931
完全经不起级联型的
21:43
and potentially economy-shattering blackouts
451
1287702
2727
和可能粉碎经济体的运作中断
21:46
caused by bad space weather or other natural disasters
452
1290429
3438
恶劣天气，其它自然灾害
21:49
or a terrorist attack.
453
1293867
1946
或是恐怖袭击造成的中断都能摧毁它
21:51
But that blackout risk disappears,
454
1295813
2731
但停电危机将不复存在
21:54
and all of the other risks are best managed,
455
1298544
1977
其它危机也能被妥善控制
21:56
with distributed renewables
456
1300536
2254
只要我们将可再生能源
21:58
organized into local micro-grids that normally interconnect,
457
1302790
4277
分配并组织成相互连结的区域性微电网
22:02
but can stand alone at need.
458
1307067
1808
需要时，它们也能独立工作
22:04
That is, they can disconnect fractally
459
1308875
2038
也就是说，它们能互相分离独立
22:06
and then reconnect seamlessly.
460
1310913
2854
也能重新建立无缝的联接
22:09
That approach is exactly what the Pentagon is adopting
461
1313767
3277
这就是五角大楼控制
22:12
for its own power supply.
462
1317044
1315
它自己内部控电的方法
22:14
They think they need that; how about the rest of us that they're defending?
463
1318359
3266
他们认为这很有必要。那么受他们保护的我们呢？
22:17
We want our stuff to work too.
464
1321625
1685
我们也希望我们的供电系统也能这样运转
22:19
At about the same cost as business as usual,
465
1323325
3570
这种方式的运营成本和其它方式一样
22:22
this would maximize national security,
466
1326895
2005
却能最大程度地保障国家安全
22:24
customer choice, entrepreneurial opportunity
467
1328900
4002
为顾客提供最多的选择，给投资家最多的机会
22:28
and innovation.
468
1332902
1623
实现最大的革新
22:30
Together, efficient use and diverse dispersed renewable supply
469
1334525
5675
总的来说，高效的使用方式和多元化的供应方式
22:36
are starting to transform the whole electricity sector.
470
1340200
2923
正在改变整个电力供应系统
22:39
Traditionally utilities build
471
1343123
1631
传统的公共事业
22:40
a lot of giant coal and nuclear plants
472
1344754
2169
建造了许多大型燃煤电厂，核电站
22:42
and a bunch of big gas plants
473
1346923
1946
一些天然气电厂
22:44
and maybe a little bit of efficiency renewables.
474
1348869
1069
可能还有一些高效可再生能源电厂
22:45
And those utilities were rewarded,
475
1349938
2529
在34个州
22:48
as they still are in 34 states,
476
1352467
2454
这些公共设施
22:50
for selling you more electricity.
477
1354921
3466
仍然因为能供应更多电力受到奖赏
22:54
However, especially where regulators
478
1358387
2798
但正是在这些管理者
22:57
are now instead rewarding cutting your bills,
479
1361185
3553
鼓励减少耗能的地方
23:00
the investments are shifting radically
480
1364738
3783
投资正在急剧转向新的方面
23:04
toward efficiency, demand response, cogeneration,
481
1368521
2531
这包括高效使用，需求响应，汽电共生
23:06
renewables and ways to knit them all together reliably
482
1371052
3369
可再生能源
23:10
with less transmission
483
1374421
1423
和耗费较少传输成本
23:11
and little or no bulk electricity storage.
484
1375844
2854
和较少电力储存的整合串联方法
23:14
So our energy future is not fate, but choice,
485
1378698
2827
所以能源的未来，不是取决于命运
23:17
and that choice is very flexible.
486
1381525
2746
而是取决于我们的选择，很有弹性的选择
23:20
In 1976, for example,
487
1384271
1600
比如说，在1976年
23:21
government and industry insisted
488
1385871
1808
政府和工业坚持
23:23
that the amount of energy needed to make a dollar of GDP
489
1387695
2584
要求花费在每一美元国内生产总值的能源量
23:26
could never go down.
490
1390279
1783
不能降低
23:27
And I heretically suggested it could go down several-fold.
491
1392062
3630
当时我却偏要提议，它可以降低七倍
23:31
Well that's what's actually happened so far.
492
1395692
2249
事实正是如此
23:33
It's fallen by half.
493
1397956
1315
耗能量减半了。
23:35
But with today's much better technologies,
494
1399271
2491
但是配合当今的高科技
23:37
more mature delivery channels and integrative design,
495
1401762
2909
更成熟的传输渠道和整合设计
23:40
we can do far more and even cheaper.
496
1404671
3900
我们可以更大程度地降低耗能和成本
23:44
So to solve the energy problem,
497
1408571
2508
所以想要解决能源问题
23:46
we just needed to enlarge it.
498
1411079
1921
我们只要把问题扩大
23:48
And the results may at first seem incredible,
499
1413000
3200
也许一开始结果显得让人难以置信
23:52
but as Marshall McLuhan said,
500
1416200
1777
但正如马歇尔·麦克卢恩所说
23:53
"Only puny secrets need protection.
501
1417977
2752
“只有微不足道的秘密需要保护
23:56
Big discoveries are protected by public incredulity."
502
1420729
6084
伟大的发现自会受到公众的质疑”
24:02
Now combine the electricity and oil revolutions,
503
1426813
3482
结合现代效率驱动的
24:06
both driven by modern efficiency,
504
1430295
1684
电力和石油革命
24:07
and you get the really big story: reinventing fire,
505
1431979
3542
就会找到关键：重燃火源
24:11
where business enabled and sped by smart policies in mindful markets
506
1435521
5131
当明智的政策孵育并加速商业发展
24:16
can lead the United States completely off oil and coal by 2050,
507
1440652
4530
就能引领美国在2050年完全摆脱石油和燃煤
24:21
saving 5 trillion dollars,
508
1445182
2320
省下5万亿美元的开销
24:23
growing the economy 2.6-fold,
509
1447502
2593
实现2.6倍的经济发展
24:25
strengthening out national security,
510
1450095
1643
强化国家安全
24:27
oh, and by the way, by getting rid of the oil and coal,
511
1451738
2985
哦，随便提一下，摆脱石油和燃煤
24:30
reducing the fossil carbon emissions by 82 to 86 percent.
512
1454723
4510
还能减少82-86%的碳排放
24:35
Now if you like any of those outcomes,
513
1459233
3334
如果你支持其中任何一项
24:38
you can support reinventing fire
514
1462567
2192
你可以支持重燃火源的行动
24:40
without needing to like all of them
515
1464759
1862
而不需要对每一项都有好感
24:42
and without needing to agree about which of them is most important.
516
1466621
3423
不需要认定哪一项最为重要
24:45
So focusing on outcomes, not motives,
517
1470044
3077
关注结果，而并动机
24:49
can turn gridlock and conflict
518
1473121
2556
可以把困境和冲突转化为
24:51
into a unifying solution to America's energy challenge.
519
1475677
4302
化解美国能源危机的统一方案
24:55
This also turns out to be the best way
520
1479979
3057
这也将是解决全球危机的
24:58
to cope with global challenges --
521
1483036
2500
最佳答案——
25:01
climate change, nuclear proliferation,
522
1485536
2579
气候变化，核扩散
25:04
energy insecurity, energy poverty --
523
1488115
2431
能源危机，能源短缺——
25:06
all of which make us less safe.
524
1490546
3646
所有这些都是不安定因素
25:10
Now our team at RMI helps smart companies
525
1494192
3687
现在我们的RMI团队正在帮助明智的公司
25:13
to get unstuck and speed this journey
526
1497879
3069
摆脱困境，加速转换进程
25:16
via six sectoral initiatives, with some more hatching.
527
1500948
3062
我们启动了六个方面的计划，正在筹划其它方面的动作
25:19
Of course there's still a lot of old thinking out there too.
528
1504010
2957
当然外界还有许多传统观念
25:22
Former oil man Maurice Strong said,
529
1506967
3177
前石油大亨莫里斯.斯特朗说
25:26
"Not all the fossils are in the fuel."
530
1510144
1946
“不是所有的化石都变成了石油。”
25:27
But as Edgar Woolard, who used to chair Dupont, reminds us,
531
1512090
4305
但是杜邦公司前总裁埃德加·伍拉德提醒我们
25:32
"Companies hampered by old thinking won't be a problem
532
1516395
4146
“被传统观念阻碍的公司不会是问题”
25:36
because," he said," they simply won't be around long-term."
533
1520541
5580
“因为它们不会长久”
25:42
I've described not just a once-in-a-civilization
534
1526121
2864
我所描述的并不只是
25:44
business opportunity,
535
1528985
1607
一个文明只有一次的商业契机
25:46
but one of the most profound transitions
536
1530592
2423
还是人类文明最重要的
25:48
in the history of our species.
537
1533015
2516
转变之一
25:51
We humans are inventing a new fire,
538
1535531
3423
人类正在发明一种新的火
25:54
not dug from below,
539
1538954
1744
并不从地下深挖
25:56
but flowing from above;
540
1540698
2907
却从地表上获得
25:59
not scarce, but bountiful;
541
1543605
2931
并不稀缺，却很丰富
26:02
not local, but everywhere;
542
1546536
1700
并不局限在一处，却四处可是
26:04
not transient, but permanent;
543
1548236
2631
并不短暂，却能持久
26:06
not costly, but free.
544
1550867
2900
并不昂贵，却是免费的
26:09
And but for a little transitional tail of natural gas
545
1553767
3400
而且和已经快用完的天然气不同
26:13
and a bit of biofuel grown in ways that sustain and endure,
546
1557167
3562
和以各种形式持续产生的生物能源不同
26:16
this new fire is flameless.
547
1560729
3709
这种新火不需要燃烧
26:20
Efficiently used, it really can do our work
548
1564438
4064
如果能高效地使用它
26:24
without working our undoing.
549
1568502
2854
它可以帮助人类发展，而不致人类毁灭
26:27
Each of you owns a piece of that $5 trillion prize.
550
1571356
4882
每个人都将享有那5万亿美元成果的一部分
26:32
And our new book "Reinventing Fire"
551
1576238
2254
我们的新书《重燃火源》
26:34
describes how you can capture it.
552
1578492
2385
就告诉你将如何取得这成果
26:36
So with the conversation just begun
553
1580877
2269
当讨论刚刚开始
26:39
at ReinventingFire.com,
554
1583146
1885
以 ReinventingFire.com 作为平台
26:40
let me invite you each
555
1585031
2131
我想邀请在座各位
26:43
to engage with us and with each other, with everyone around you,
556
1587162
3838
和我们，和在座各位，和各位身边的每个人
26:46
to help make the world richer, fairer,
557
1591000
2792
一起努力让世界更富饶，更公平
26:49
cooler and safer
558
1593792
2608
更凉爽，更安全
26:52
by together reinventing fire.
559
1596400
2808
只要我们一起重燃火源
26:55
Thank you.
560
1599208

ABOUT THE SPEAKER
Amory Lovins - Physicist, energy guruIn his new book, "Reinventing Fire," Amory Lovins shares ingenious ideas for the next era of energy.
Why you should listen
Amory Lovins was worried (and writing) about energy long before global warming was making the front -- or even back -- page of newspapers. Since studying at Harvard and Oxford in the 1960s, he's written dozens of books, and initiated ambitious projects -- cofounding the influential, environment-focused Rocky Mountain Institute; prototyping the ultra-efficient Hypercar -- to focus the world's attention on alternative approaches to energy and transportation.
His critical thinking has driven people around the globe -- from world leaders to the average Joe -- to think differently about energy and its role in some of our biggest problems: climate change, oil dependency, national security, economic health, and depletion of natural resources.
Lovins offers solutions as well. His new book and site, Reinventing Fire, offers actionable solutions for four energy-intensive sectors of the economy: transportation, buildings, industry and electricity. Lovins has always focused on solutions that conserve natural resources while also promoting economic growth; Texas Instruments and Wal-Mart are just two of the mega-corporations he has advised on improving energy efficiency.
