聽力原文如下
<code>1.First of all, I'm a geek.
首先，我是一位書呆子。
2.I'm an organic food-eating, carbon footprint-minimizing, robotic surgery geek, and I really want to build green, but I'm very suspicious
我吃有機食品， 我是一位低碳生活者，我沉迷於機器人手術， 而且我特別想建造綠色， 但我是個多疑的人
3.of all of these well-meaning articles, people long on moral authority and short on data telling me how to do these kinds of things.
特別是對於這些好意的文章們， 人們常常注重道德規範 而缺少數據的支持 以來告訴我如何去做這些事。
4.And so I have to figure this out for myself.
所以我只能自己找尋答案。
5.For example: Is this evil?
例如：這是邪惡的嗎？
6.I have dropped a blob of organic yogurt from happy self-actualized local cows on my counter top, and I grab a paper towel, and I want to wipe it up.
我掉了一滴有機酸奶 在我的桌面上， 它來自當地的奶牛， 然後我拿來一張紙巾，我想把它擦乾淨。
7.But can I use a paper towel? (Laughter) The answer to this can be found in embodied energy.
但是我能用這個紙巾嗎？（笑聲） 這個答案能從內蘊能量中找到。
8.This is the amount of energy that goes into any paper towel or embodied water.
這就是任何一張手紙或者水的 內涵能源。
9.And every time I use a paper towel, I am using this much virtual energy and water.
而每次我使用紙巾， 我會使用這麼多 能量和水。
10.Wipe it up, throw it away.
擦乾淨它，再把它扔掉。
11.Now, if I compare that to a cotton towel that I can use a thousand times, I don't have a whole lot of embodied energy until I wash that yogurty towel.
現在，如果我用棉布和他進行對比 我能重複用上千次， 我不需要花費那麼多內蘊能量 直到我需洗淨這個酸奶抹布為止。
12.This is now operating energy.
現在我要說的是操作能量。
13.So if I throw my towel in the washing machine, I've now put energy and water back into that towel, unless I use a front-loading high-efficiency washing machine,
如果我把抹布放入洗衣機， 我需要能量和水 去洗這個抹布， 除非我用的是前置型高效洗衣機，
14.and then it looks a little bit better.
而它只是看上去好一點兒。
15.But what about a recycled paper towel that comes in those little half sheets?
但是一個可回收的紙巾會怎麼樣 特別是那些半張大小的？
16.Well, now a paper towel looks better.
恩，現在一張紙巾看起來好多了。
17.Screw the paper towels. Let's go to a sponge.
別想紙巾了。讓我們看看海綿，
18.I wipe it with a sponge, and I put it under the running water, and I have a lot less energy and a lot more water, unless you're like me and you leave the handle
我用一個海綿擦，然後用水沖洗， 然後我用很少的能量和更多的水， 除非你像我這樣且你把手柄放在熱水的一邊
19.in the position of hot even when you turn it on, and then you start to use more energy, or worse, you let it run until it's warm to rinse out your towel.
但即使當你打開它的時候， 你還是得使用更多的能量， 更糟糕的是，你或許會讓水流著直到變熱為止 以洗淨你的抹布。
20.And now all bets are off.
現在我們不打賭了。
21.(Laughter) So what this says is that sometimes the things that you least expect, the position in which you put the handle, have a bigger effect than any of those other things
（笑) 所以在這裡要指出的是 有時候你最不在意的事， 比如你放手柄的位置， 比起其他的事情會造成更大的影響
22.that you were trying to optimize.
特別是那些你試圖去優化的事。
23.Now imagine someone as twisted as me trying to build a house.
現在想象一下一個人像我一樣瘋狂 的去試圖建造一個房子。
24.(Laughter) That's what my husband and I are doing right now.
（笑聲） 那正是我和我丈夫正在做的事。
25.And so, we wanted to know how green could we be.
而我們想知道我們到底可以有多環保。
26.And there's a thousand and one articles out there telling us how to make all these green trade-offs.
而且那裡有數以千計的文章 來告訴我們怎麼去做綠色的交換。
27.And they are just as suspect in telling us to optimize these little things around the edges and missing the elephant in the living room.
而且他們就是 告訴我們去優化一些邊角小物 從而忽略了眼前龐然大物。
28.Now, the average house has about 300 megawatt hours of embodied energy in it.
現在，平均每家 需要消耗300千瓦時 的內蘊能量。
29.This is the energy it takes to make it, millions and millions of paper towels.
這些能量可以製造出， 成千上萬的紙巾。
30.We wanted to know how much better we could do.
我們想知道我怎麼能做的更好。
31.And so, like many people, we start with a house on a lot, and I'm going to show you a typical construction on the top and what we're doing on the bottom.
所以，就如同很多人一樣， 我們從普通的房子開始， 同時我會向你們展示一個普通房頂的建設過程 而且我們在底下做什麼。
32.So first, we demolish it.
第一，我們先消減一部分。
33.It takes some energy, but if you deconstruct it, you take it all apart, you use the bits, you can get some of that energy back.
它會消耗一些能量，但是如果你拆除它， 你把它都拆了，你用一些， 你可以回收一些能量。
34.We then dug a big hole to put in a rainwater catchment tank to take our yard water independent.
我們之後挖了一個大洞 把雨水收集到水箱裡 以用來獨立灌溉我們的花園。
35.And then we poured a big foundation for passive solar.
然後我們建造一個大型 的太陽能收集板。
36.Now, you can reduce the embodied energy by about 25 percent by using high fly ash concrete.
現在，通過使用塵土飛揚的水泥 你可以減免 25%的能耗。
37.We then put in framing.
我們之後做了一個框架。
38.And so this is framing, lumber, composite materials, and it's kind of hard to get the embodied energy out of that, but it can be a sustainable resource
這個框架是用木頭 和合成材料作成的， 所以很難收回這些能量， 如果你用F.S.C. 驗證的木材
39.if you use F.S.C. certified lumber.
它們是可成為可持續性的能源。
40.We then go on to the first thing that was very surprising.
我們之後發現 一件驚奇的事。
41.If we put aluminum windows in this house, we would double the energy use right there.
如果用鋁製窗裝飾我們的房屋， 我們能雙倍利用這能量。
42.Now, PVC is a little bit better, but still not as good as the wood that we chose.
PVC比這好一點， 但是還是沒辦法媲美我們選的木頭。
43.We then put in plumbing, electrical and HVAC, and insulate.
我們之後安裝了電器、採暖通風與空調系統 抽水馬桶 以及隔熱設備。
44.Now, spray foam is an excellent insulator, it fills in all the cracks, but it is pretty high embodied energy.
當下，噴射式泡沫是非常好的隔熱材料，它可以填入所有的地方， 但是它非常耗費能量。
45.And, sprayed-in cellulose or blue-jeans is a much lower energy alternative to that.
噴灑式纖維素或者牛仔褲布料 是可選用的低耗能替代品。
46.We also used straw bale in fill for our library, which has zero embodied energy.
我們同時也用秸稈包 填充在我們的書房， 而這些是零耗能的東西。
47.When it comes time to sheetrock, if you use EcoRock, it's about a quarter of the embodied energy of standard sheetrock.
當我們使用石膏灰膠紙夾板， 如果你用EcoRock，它只耗費的 普通石膏灰膠紙夾板?的能量。
48.And then you get to the finishes, the subject of all of those "go green" articles.
然後你完成的時候， 回顧下那些所有關於“綠色”的文章。
49.And on the scale of a house, they almost make no difference at all.
它們對於整間房子的調控， 我們和他們幾乎是一樣。
50.And yet, all the press is focused on that.
但所有的媒體都在關注它們。
51.Except for flooring.
除了地面。
52.If you put carpeting in your house, it's about a tenth of the embodied energy of the entire house, unless you use concrete or wood for a much lower embodied energy.
如果你在家裡放入地毯， 它大概佔用整間屋子消耗能量的1/10， 除非你選擇水泥或者木頭 這可使內蘊能量總量更低。
53.So now we add in the final construction energy, we add it all up, and we've built a house for less than half of the typical embodied energy for building a house like this.
現在我們把能量總量加起來， 我們已經建造了一座同樣類型 但是隻消耗了一般房子的一半內蘊能量。
54.But before we pat ourselves too much on the back, we have poured 151 megawatt hours of energy into constructing this house, when there was a house there before.
但是在我們過多拍我們自己的 後背以表彰我們自己之前， 我們已經消耗了151千瓦時 去建造這個房子， 當那兒之前有一座房子。
55.And so the question is: How could we make that back?
所以問題是： 我們如何把那些找回來？
56.And so if I run my new energy-efficient house forward, compared with the old, non-energy-efficient house, we make it back in about six years.
而且如果繼續使用我的新節能房， 對比老式的，非節能房， 我們回到了大概6年前。
57.Now, I probably would have upgraded the old house to be more energy-efficient.
現在，我大概會去升級改造那座舊房子 使它變的更加節能。
58.And in that case, it would take me more about 20 years to break even.
如果是那個情況， 它會耗費我大概20年去平衡。
59.Now, if I hadn't paid attention to embodied energy, it would have taken us over 50 years to break even compared to the upgraded house.
現在，如果我不去關注能量總量， 它會耗費我們 超過50年的時間去平衡 對比已經升級過的房子。
60.So what does this mean?
這意味著什麼？
61.On the scale of my portion of the house, this is equivalent to about as much as I drive in a year, it's about five times as much as if I went entirely vegetarian.
按我建造房子的比例， 這相當於 我開車一年， 大概是五倍於 我成為完全素食主義者。
62.But my elephant in the living room flies.
但是在我眼前最終顯而易見的事中。
63.Clearly, I need to walk home from TED.
顯然，我需要從TED走路回家。
64.But all the calculations for embodied energy are on the blog.
但是在Blog中有對於所有 能量總量的計算。
65.And, remember, it's sometimes the things that you are not expecting to be the biggest changes that are.
同時，記住，有時候你從沒有期待的事情 正是最大的變化所在。/<code>
