How many of you have checked your email today?
1
12594
2539
在座有多少人今天查看過電子郵件?
00:15
Come on, raise your hands.
2
15133
1896
好,請舉手
00:17
How many of you are checking it right now?
3
17029
2131
有多少人現在正在查看?
00:19
(Laughter)

(笑聲)
00:20
And how about finances? Anybody check that today?
5

金融帳戶呢?今天有人查看了嗎?
00:23
Credit card, investment account?

信用卡、投資帳戶呢?
00:25
How about this week?

3953
本週內有看過的?
00:29
Now, how about your household energy use?
8
29659
3117
好,家庭能源使用情況呢?
00:32
Anybody check that today?
9
32776

今天有人查看過嗎?
00:34
This week? Last week?
10

這星期或上星期?
00:38
A few energy geeks spread out across the room.
11
38866
3128
現場有幾位能源達人
00:41
It's good to see you guys.
12
41994
2569
很高興見到你們
00:44
But the rest of us -- this is a room filled with people
13
44563
3235
但其餘聽眾-這個房間裡擠滿
00:47
who are passionate about the future of this planet,
14
47798
2982
關心地球未來的人
00:50
and even we aren't paying attention
15
50780
1831
即使我們這些人
00:52
to the energy use that's driving climate change.
16
52611
2960
對導致氣候變化的能源使用都不甚在意
00:55
The woman in the photo with me is Harriet.
17
55571
2655
這位與我合照的女士名叫 Harriet
00:58
We met her on our first family vacation.
18
58226
2537
我們是在第一次全家出遊時碰到她的
01:00
Harriet's paying attention to her energy use,
19
60763
2362
Harriet 十分關心能源使用情況
01:03
and she is decidedly not an energy geek.
20
63125
2860
但她絕非能源達人
01:05
This is the story of how Harriet came to pay attention.
21
65985
5239
我想分享的是 為何Harriet開始關心能源使用的故事
01:11
This is coal,
22
71224
2029
這是煤炭
01:13
the most common source of electricity on the planet,
23
73253
3357
地球上最常見的電力來源
01:16
and there's enough energy in this coal
24
76610
3224
這些煤炭蘊藏足夠的能量
01:19
to light this bulb for more than a year.
25
79834
3952
可點亮這個燈泡超過一年
01:23
But unfortunately, between here and here,
26
83786
2071
但不幸的是,從這裡到這裡
01:25
most of that energy is lost to things
27
85857
1432
大部分能量
01:27
like transmission leakage and heat.
28
87289
2885
因傳導和熱能消耗等因素而流失
01:30
In fact, only 10 percent ends up as light.
29
90174
3579
事實上,最後只有 10% 能量以光能形式呈現
01:33
So this coal will last a little bit more than a month.
30
93753
4008
因此這些煤炭僅能維持一個多月的照明
01:37
If you wanted to light this bulb for a year,
31
97761
2609
如果你想讓這個燈泡照明一年
01:40
you'd need this much coal.
32
100370
5038
需使用這麼多煤炭
01:45
The bad news here is that, for every unit of energy we use,
33
105408
3044
壞消息是,每當我們使用一單位能量
01:48
we waste nine.
34
108452
2073
即浪費九單位能量
01:50
That means there's good news,
35
110525
1631
這意味著其中也有好消息
01:52
because for every unit of energy we save,
36
112156
2583
因為每當我們節省一單位能量
01:54
we save the other nine.
37
114739
3265
即省下其餘九單位能量
01:58
So the question is, how can we get the people in this room
38
118004
5281
因此問題在於 我們如何使現場聽眾
02:03
and across the globe to start paying attention
39
123300
2966
及全世界的人開始關心
02:06
to the energy we're using,
40
126266
2086
我們所使用的能源
02:08
and start wasting less of it?
41
128352
2976
並開始減少能源浪費?
02:11
The answer comes from a behavioral science experiment
42
131328
2387
答案來自某個行為科學實驗
02:13
that was run one hot summer, 10 years ago,
43
133715
3381
於十年前一個炎熱的夏天進行
02:17
and only 90 miles from here,
44
137096
2136
實驗場所位於距離這裡只有90英哩
02:19
in San Marcos, California.
45
139232
3376
的加州聖馬克斯
02:22
Graduate students put signs on every door in a neighborhood,
46
142608
2681
研究生在某街區的每扇門上貼紙條
02:25
asking people to turn off their air conditioning
47
145289
2821
請住戶關上空調
02:28
and turn on their fans.
48
148110
2210
使用電扇
02:30
One quarter of the homes received a message that said,
49
150320
2288
四分之一住戶收到的訊息是
02:32
did you know you could save 54 dollars a month this summer?
50
152608
2318
「知道嗎? 這個夏季你每月可省下54美元」
02:34
Turn off your air conditioning, turn on your fans.
51
154926
1818
「只要關上空調,使用電扇」
02:36
Another group got an environmental message.
52
156744
1834
另一組收到的是與環保有關的訊息
02:38
And still a third group got a message about
53
158578
2089
第三組收到的訊息是
02:40
being good citizens, preventing blackouts.
54
160667
2680
「做個好公民,避免造成停電」
02:43
Most people guessed that money-saving message would work best of all.
55
163347
3717
多數人預測節省開支的訊息效果最佳
02:47
In fact, none of these messages worked.
56
167064
2613
事實上,沒有一條訊息起作用
02:49
They had zero impact on energy consumption.
57
169677
2856
它們對能源消耗情況沒有任何影響
02:52
It was as if the grad students hadn't shown up at all.
58
172533
4121
彷彿那些研究生從來沒有造訪過
02:56
But there was a fourth message,
59
176654
1820
但還有第四條訊息
02:58
and this message simply said,
60
178474
2123
這條訊息只寫著
03:00
"When surveyed, 77 percent of your neighbors
61
180597
3910
「根據調查,你有 77 % 鄰居」
03:04
said that they turned off their air conditioning and turned on their fans.
62
184507
2490
「說他們關上空調,使用電扇」
03:06
Please join them. Turn off your air conditioning
63
186997
1805
「請加入他們的行列,
03:08
and turn on your fans."
64
188802
1261
關上空調,使用電扇」
03:10
And wouldn't you know it, they did.
65
190063
2697
你們猜怎麼著?他們如法炮製
03:12
The people who received this message
66
192760
1954
收到這則訊息的人
03:14
showed a marked decrease in energy consumption
67
194714
2522
顯著地減少了能源消耗
03:17
simply by being told what their neighbors were doing.
68
197236
3411
只因得知鄰居的做法
03:20
So what does this tell us?
69
200647
1700
因此,這告訴我們什麼?
03:22
Well, if something is inconvenient,
70
202347
2217
好,如果某件事令人感到不便
03:24
even if we believe in it,
71
204564
1989
即使我們深信不疑
03:26
moral suasion, financial incentives, don't do much to move us --
72
206553
3878
道德勸說、經濟鼓勵 不會使我們產生多少動力
03:30
but social pressure, that's powerful stuff.
73
210431
3670
但社會壓力則是十分強大的力量
03:34
And harnessed correctly, it can be a powerful force for good.
74
214101
3618
若正確使用 可成為有益事物的強大力量
03:37
In fact, it already is.
75
217719
2165
確實如此
03:39
Inspired by this insight, my friend Dan Yates and I
76
219884
2632
受到這個觀點的啟發,我和朋友 Dan Yates
03:42
started a company called Opower.
77
222516
2176
成立一間名叫 Opower 的公司
03:44
We built software and partnered with utility companies
78
224692
2469
我們建構軟體,與希望幫助
03:47
who wanted to help their customers save energy.
79
227161
2803
顧客節約能源的公共事業公司合作
03:49
We deliver personalized home energy reports
80
229964
3066
我們寄送個人化家庭能源報告
03:53
that show people how their consumption
81
233030
1718
讓人們瞭解他們的能源消耗量
03:54
compares to their neighbors in similar-sized homes.
82
234748
2872
和擁有尺寸相近房屋之鄰居的比較值
03:57
Just like those effective door hangers,
83
237620
2240
如同那些效果絕佳的門上留言
03:59
we have people comparing themselves to their neighbors,
84
239860
2464
我們讓住戶與鄰居進行比較
04:02
and then we give everyone targeted recommendations
85
242324
2516
然後給他們目標性建議
04:04
to help them save.
86
244840
1650
幫助他們節約能源
04:06
We started with paper, we moved to a mobile application,
87
246490
2306
我們從紙本開始,發展到手機應用程式
04:08
web, and now even a controllable thermostat,
88
248796
2929
網路,甚至恒溫控制器
04:11
and for the last five years we've been running
89
251725
2017
過去五年中,我們持續進行
04:13
the largest behavioral science experiment in the world.
90
253742
4403
世上最大的行為科學實驗
04:18
And it's working.
91
258145
1664
它確實有效
04:19
Ordinary homeowners and renters have saved
92
259809
2097
一般住戶及租屋者至今已省下
04:21
more than 250 million dollars on their energy bills,
93
261906
3140
超過2億5千萬美元的能源支出
04:25
and we're just getting started.
94
265046
1513
這只是最初成效
04:26
This year alone, in partnership with more than 80 utilities
95
266559
3260
光是今年,我們與超過80個公共機構合作
04:29
in six countries, we're going to generate
96
269819
2254
遍及六個國家,我們正致力於
04:32
another two terawatt hours of electricity savings.
97
272073
3152
額外節省2兆瓦小時用電量
04:35
Now, the energy geeks in the room know two terawatt hours,
98
275225
2041
好,現場的能源達人瞭解何謂2兆瓦小時
04:37
but for the rest of us, two terawatt hours
99
277266
2039
但為了讓其餘聽眾瞭解,2兆瓦小時能量
04:39
is more than enough energy to power every home
100
279305
3339
足以供應聖路易斯及鹽湖城所有家庭
04:42
in St. Louis and Salt Lake City combined
101
282644
3294
足以供應聖路易斯及鹽湖城所有家庭
04:45
for more than a year.
102
285938
1568
超過一年的用電量
04:47
Two terawatt hours, it's roughly half
103
287506
1966
2兆瓦小時相當於
04:49
what the U.S. solar industry produced last year.
104
289472
2586
去年美國太陽能工業產量的一半
04:52
And two terawatt hours? In terms of coal,
105
292058
3591
2兆瓦小時,以煤炭計算
04:55
we'd need to burn 34 of these wheelbarrows
106
295649
3157
每分鐘需燃燒相當於34輛手推車的煤炭
04:58
every minute around the clock every day for an entire year
107
298806
3996
持續燃燒一整年
05:02
to get two terawatt hours of electricity.
108
302802
2104
才能產生2兆瓦小時電力
05:04
And we're not burning anything.
109
304906
1317
我們不需要燃燒任何東西
05:06
We're just motivating people to pay attention
110
306223
1728
我們只是促使人們關心能源問題
05:07
and change their behavior.
111
307951
3013
改變他們的行為
05:10
But we're just one company, and this is just
112
310964
2290
但我們只是一家公司,
05:13
scratching the surface.
113
313254
2137
這只是初步嘗試
05:15
Twenty percent of the electricity in homes is wasted,
114
315391
3565
家用電力有 20% 遭到浪費
05:18
and when I say wasted, I don't mean that people have
115
318956
2004
我所謂的浪費,並非指人們使用
05:20
inefficient lightbulbs. They may.
116
320960
3353
低效率燈泡,這無傷大雅
05:24
I mean we leave the lights on in empty rooms,
117
324313
3144
我指的是空無一人的房間仍亮著燈
05:27
and we leave the air conditioning on when nobody's home.
118
327457
3030
家中空無一人時仍開著空調
05:30
That's 40 billion dollars a year wasted
119
330487
3084
這導致每年浪費價值400億美元的電力
05:33
on electricity that does not contribute to our well-being
120
333571
3249
這對生活來說不構成影響
05:36
but does contribute to climate change.
121
336820
2647
卻足以導致氣候變化
05:39
That's 40 billion -- with a B --
122
339467
2120
400億美元
05:41
every year in the U.S. alone.
123
341587
2283
僅是美國每年浪費的電力價值
05:43
That's half our coal usage right there.
124
343870
3365
相當於我國一半的煤炭使用量
05:47
Now thankfully, some of the world's best material scientists
125
347235
2772
現在,值得慶幸的是 一些世上最傑出的材料科學家
05:50
are looking to replace coal with sustainable resources
126
350007
3506
正致力於尋找替代煤炭的可持續能源
05:53
like these,
127
353513
1138
例如這些(風力發電)
05:54
and this is both fantastic and essential.
128
354651
3498
這是很棒且必要的
05:58
But the most overlooked resource to get us
129
358149
2038
但使我們邁向可持續能源的未來
06:00
to a sustainable energy future, it isn't on this slide.
130
360187
3546
卻最被忽視的資源, 並未顯示在這張投影片上
06:03
It's in this room. It's you, and it's me.
131
363733
4656
它在這個房間裡,那就是你們,還有我
06:08
And we can harness this resource
132
368389
2684
我們可以駕馭這種資源
06:11
with no new material science
133
371073
1837
不需使用新型材料科學技術
06:12
simply by applying behavioral science.
134
372910
3192
只需應用行為科學
06:16
We can do it today, we know it works,
135
376102
2084
我們可以從今天開始 我們知道它確實有效
06:18
and it will save us money right away.
136
378186
3728
可立即替我們省錢
06:21
So what are we waiting for?
137
381914
2751
那我們還等什麼?
06:24
Well, in most places, utility regulation
138
384665
2727
好,在大部分地區,公共事業的監管
06:27
hasn't changed much since Thomas Edison.
139
387392
4316
自愛迪生以來並無多大改變
06:31
Utilities are still rewarded when their customers
140
391708
2930
公共事業依然獎勵消費者
06:34
waste energy.
141
394638
1564
浪費能源
06:36
They ought to be rewarded for helping their customers save it.
142
396202
3803
他們應該因幫助消費者節約能源而獲得獎勵
06:40
But this story is much more than about household energy use.
143
400005
3406
但這個故事不僅是關於家庭能源的使用
06:43
Take a look at the Prius.
144
403411
2062
以Prius為例 (Toyota生產的油電混合動力車)
06:45
It's efficient not only because Toyota invested in material science
145
405473
3022
它的高效能不僅是因為 Toyota 投入材料科學研發
06:48
but because they invested in behavioral science.
146
408495
2475
也因為他們應用了行為科學
06:50
The dashboard that shows drivers how much energy
147
410970
2140
駕駛可從儀表板得知
06:53
they're saving in real time
148
413110
1964
即時節約了多少能源
06:55
makes former speed demons
149
415074
1515
使之前的飆車大王
06:56
drive more like cautious grandmothers.
150
416589
2753
變得更像謹慎的祖母
06:59
Which brings us back to Harriet.
151
419342
2564
這讓我們的故事回到 Harriet 身上
07:01
We met her on our first family vacation.
152
421906
2188
我們是在第一次全家出遊活動中與她相遇
07:04
She came over to meet my young daughter,
153
424094
2187
她上前來看我的小女兒
07:06
and she was tickled to learn that my daughter's name
154
426281
2171
很高興知道
07:08
is also Harriet.
155
428452
2054
我女兒也叫Harriet
07:10
She asked me what I did for a living,
156
430506
1425
她問我從事什麼工作
07:11
and I told her, I work with utilities
157
431931
1545
我告訴她,我與公共事業機構合作
07:13
to help people save energy.
158
433476
1876
