0:00:00.300,0:00:02.341 I was only four years old 0:00:02.365,0:00:05.276 when I saw my mother[br]load a washing machine 0:00:05.300,0:00:07.482 for the very first time in her life. 0:00:07.943,0:00:09.919 That was a great day for my mother. 0:00:10.431,0:00:13.276 My mother and father[br]had been saving money for years 0:00:13.300,0:00:15.340 to be able to buy that machine, 0:00:15.364,0:00:17.410 and the first day it was going to be used, 0:00:17.434,0:00:20.573 even Grandma was invited[br]to see the machine. 0:00:20.597,0:00:21.733 (Laughter) 0:00:21.757,0:00:24.276 And Grandma was even more excited. 0:00:24.300,0:00:28.600 Throughout her life, she had been[br]heating water with firewood, 0:00:28.624,0:00:32.634 and she had hand-washed laundry[br]for seven children. 0:00:32.658,0:00:37.686 And now, she was going to watch[br]electricity do that work. 0:00:38.300,0:00:42.551 My mother carefully opened the door, 0:00:42.575,0:00:46.004 and she loaded the laundry[br]into the machine, 0:00:47.035,0:00:48.227 like this. 0:00:48.251,0:00:50.452 And then, when she closed the door, 0:00:50.476,0:00:52.276 Grandma said, "No, no, no, no! 0:00:52.300,0:00:55.300 Let me! Let me push the button!" 0:00:55.324,0:00:56.336 (Laughter) 0:00:56.360,0:00:58.982 And Grandma pushed the button, 0:00:59.006,0:01:01.561 and she said, "Oh, fantastic! 0:01:01.585,0:01:05.347 I want to see this! Give me a chair![br]Give me a chair! I want to see it," 0:01:05.371,0:01:08.102 and she sat down in front of the machine, 0:01:08.126,0:01:11.717 and she watched[br]the entire washing program. 0:01:11.741,0:01:12.743 (Laughter) 0:01:12.767,0:01:14.192 She was mesmerized. 0:01:14.618,0:01:19.046 To my grandmother,[br]the washing machine was a miracle. 0:01:19.966,0:01:23.398 Today, in Sweden and other rich countries, 0:01:23.422,0:01:27.158 people are using[br]so many different machines. 0:01:27.182,0:01:29.167 Look -- the homes are full of machines. 0:01:29.191,0:01:31.276 I can't even name them all. 0:01:31.300,0:01:34.783 And they also, when they want to travel, 0:01:34.807,0:01:36.971 they use flying machines 0:01:36.995,0:01:39.663 that can take them to remote destinations. 0:01:39.687,0:01:40.912 And yet, in the world, 0:01:40.936,0:01:44.720 there are so many people[br]who still heat the water on fire, 0:01:44.744,0:01:47.235 and they cook their food on fire. 0:01:47.259,0:01:49.321 Sometimes they don't even[br]have enough food. 0:01:49.971,0:01:52.276 And they live below the poverty line. 0:01:52.300,0:01:55.161 There are two billion fellow human beings 0:01:55.185,0:01:57.892 who live on less than two dollars a day. 0:01:57.916,0:02:01.051 And the richest people over there --[br]there's one billion people, 0:02:01.075,0:02:04.413 and they live above[br]what I call the "air line" -- 0:02:04.437,0:02:05.454 (Laughter) 0:02:05.478,0:02:08.923 because they spend[br]more than 80 dollars a day 0:02:08.947,0:02:10.840 on their consumption. 0:02:10.864,0:02:13.513 But this is just one, two,[br]three billion people, 0:02:13.537,0:02:16.328 and obviously, there are[br]seven billion people in the world, 0:02:16.352,0:02:19.825 so there must be one, two,[br]three, four billion people more 0:02:19.849,0:02:23.027 who live in between[br]the poverty and the air line. 0:02:23.051,0:02:24.796 They have electricity, 0:02:24.820,0:02:27.570 but the question is:[br]How many have washing machines? 0:02:28.610,0:02:33.121 I've done the scrutiny of market data,[br]and I've found that, indeed, 0:02:33.145,0:02:36.717 the washing machine[br]has penetrated below the air line, 0:02:36.741,0:02:39.994 and today, there's an additional[br]one billion people out there 0:02:40.018,0:02:42.276 who live above the "wash line." 0:02:42.300,0:02:44.276 (Laughter) 0:02:44.709,0:02:48.345 And they consume[br]for more than 40 dollars per day. 0:02:48.369,0:02:51.107 So two billion have access[br]to washing machines. 0:02:51.131,0:02:54.058 And the remaining five billion -- 0:02:54.082,0:02:55.348 how do they wash? 0:02:55.372,0:02:56.978 Or, to be more precise, 0:02:57.002,0:03:00.349 how do most of the women[br]in the world wash? 0:03:00.373,0:03:03.584 Because it remains the hard work[br]for women to wash. 0:03:04.329,0:03:06.390 They wash like this: by hand. 0:03:07.438,0:03:11.735 It's hard, time-consuming labor, 0:03:11.759,0:03:14.936 which they have to do[br]for hours every week. 0:03:14.960,0:03:18.109 And sometimes they also have[br]to bring water from far away 0:03:18.133,0:03:19.562 to do the laundry at home, 0:03:19.586,0:03:23.148 or they have to bring the laundry[br]away to a stream far off. 0:03:23.172,0:03:25.348 And they want the washing machine. 0:03:25.927,0:03:29.580 They don't want to spend[br]such a large part of their life 0:03:29.604,0:03:30.967 doing this hard work 0:03:30.991,0:03:33.449 with so relatively low productivity. 0:03:34.092,0:03:36.304 And there's nothing[br]different in their wish 0:03:36.328,0:03:38.019 than it was for my grandma. 0:03:38.043,0:03:40.388 Look here, two generations[br]ago in Sweden -- 0:03:40.412,0:03:42.276 picking water from the stream, 0:03:42.300,0:03:45.145 heating with firewood[br]and washing like that. 0:03:45.169,0:03:48.151 They want the washing machine[br]in exactly the same way. 0:03:48.175,0:03:51.495 But when I lecture[br]to environmentally concerned students, 0:03:51.519,0:03:55.622 they tell me, "No, everybody in the world[br]cannot have cars and washing machines." 0:03:56.570,0:03:57.899 How can we tell this woman 0:03:57.923,0:04:00.489 that she isn't going[br]to have a washing machine? 0:04:00.513,0:04:03.925 And then I ask my students --[br]over the last two years, I've asked -- 0:04:03.949,0:04:05.973 "How many of you don't use a car?" 0:04:05.997,0:04:09.838 And some of them proudly raise their hand[br]and say, "I don't use a car." 0:04:10.300,0:04:12.631 And then I put the really tough question: 0:04:12.655,0:04:16.568 "How many of you hand-wash[br]your jeans and your bedsheets?" 0:04:16.592,0:04:19.276 And no one raised their hand. 0:04:19.938,0:04:24.276 Even the hardcore in the green movement[br]use washing machines. 0:04:24.300,0:04:26.441 (Laughter) 0:04:27.990,0:04:30.447 So how come [this is][br]something that everyone uses 0:04:30.471,0:04:32.358 and they think others will not stop it? 0:04:32.382,0:04:33.631 What is special with this? 0:04:33.655,0:04:36.519 I had to do an analysis[br]about the energy use in the world. 0:04:36.543,0:04:37.709 Here we are. 0:04:37.733,0:04:40.249 Look here. You see[br]the seven billion people up there? 0:04:40.273,0:04:42.276 The air people, the wash people, 0:04:42.300,0:04:45.088 the bulb people and the fire people. 0:04:45.112,0:04:47.129 One unit like this 0:04:47.153,0:04:52.276 is an energy unit of fossil fuel --[br]oil, coal or gas. 0:04:52.300,0:04:55.887 That's what most of the electricity[br]and the energy in the world is. 0:04:55.911,0:04:59.030 And it's 12 units used[br]in the entire world, 0:04:59.054,0:05:01.861 and the richest one billion,[br]they use six of them. 0:05:02.300,0:05:05.653 Half of the energy is used[br]by one seventh of the world population. 0:05:05.677,0:05:07.816 And these ones, who have washing machines 0:05:07.840,0:05:09.807 but not a house full of other machines, 0:05:09.831,0:05:11.021 they use two. 0:05:11.647,0:05:13.903 This group uses three, one each. 0:05:14.529,0:05:16.101 And they also have electricity. 0:05:16.125,0:05:18.276 And over there,[br]they don't even use one each. 0:05:18.300,0:05:19.621 That makes 12 of them. 0:05:20.069,0:05:21.740 But the main concern 0:05:21.764,0:05:25.435 for the environmentally interested[br]students -- and they are right -- 0:05:25.459,0:05:26.909 is about the future. 0:05:27.894,0:05:29.060 What are the trends? 0:05:29.084,0:05:32.743 If we just prolong the trends,[br]without any real advanced analysis, 0:05:32.767,0:05:33.934 to 2050, 0:05:33.958,0:05:37.086 there are two things[br]that can increase the energy use: 0:05:37.110,0:05:40.095 first, population growth;[br]second, economic growth. 0:05:40.697,0:05:44.163 Population growth will mainly occur[br]among the poorest people here, 0:05:44.187,0:05:46.025 because they have high child mortality 0:05:46.049,0:05:47.876 and they have many children per woman. 0:05:47.900,0:05:49.783 And that will get you two extra, 0:05:49.807,0:05:52.039 but that won't change[br]the energy use very much. 0:05:52.063,0:05:54.063 What will happen is economic growth. 0:05:54.087,0:05:56.843 The best of here[br]in the emerging economies -- 0:05:56.867,0:05:58.566 I call them "the New East" -- 0:05:58.590,0:06:00.276 they will jump the air line. 0:06:00.300,0:06:01.939 "Wopp!" they will say. 0:06:01.963,0:06:05.398 And they will start to use as much[br]as the Old West are doing already. 0:06:05.422,0:06:06.498 (Laughter) 0:06:06.522,0:06:08.803 And these people,[br]they want the washing machine. 0:06:08.827,0:06:10.276 I told you. They'll go there. 0:06:10.300,0:06:12.130 And they will double their energy use. 0:06:12.154,0:06:15.278 And we hope that the poor people[br]will get into the electric light. 0:06:15.302,0:06:18.714 And they'll get a two-child family[br]without a stop in population growth. 0:06:18.738,0:06:21.957 But the total energy consumption[br]will increase to 22 units. 0:06:21.981,0:06:24.783 And these 22 units -- 0:06:24.807,0:06:27.392 still, the richest people[br]use most of them. 0:06:28.862,0:06:30.237 So what needs to be done? 0:06:30.261,0:06:32.238 Because the risk, 0:06:32.262,0:06:35.005 the high probability[br]of climate change is real. 0:06:35.417,0:06:36.821 It's real. 0:06:36.845,0:06:39.612 Of course, they must be[br]more energy efficient. 0:06:40.516,0:06:42.630 They must change[br]their behavior in some way. 0:06:42.654,0:06:45.090 They must also start[br]to produce green energy, 0:06:45.114,0:06:46.339 much more green energy. 0:06:46.363,0:06:49.735 But until they have the same[br]energy consumption per person, 0:06:49.759,0:06:51.670 they shouldn't give advice to others -- 0:06:51.694,0:06:53.190 what to do and what not to do. 0:06:53.214,0:06:54.338 (Laughter) 0:06:54.362,0:06:55.540 (Applause) 0:06:55.564,0:07:00.309 Here, we can get more[br]green energy all over. 0:07:00.333,0:07:01.981 This is what we hope might happen. 0:07:02.005,0:07:03.988 It's a real challenge in the future. 0:07:04.379,0:07:08.035 But I can assure you[br]that this woman in the favela in Rio, 0:07:08.059,0:07:09.828 she wants a washing machine. 0:07:09.852,0:07:12.214 She's very happy[br]about her minister of energy 0:07:12.238,0:07:14.214 that provided electricity to everyone -- 0:07:14.238,0:07:17.815 so happy that she even voted for her. 0:07:17.839,0:07:19.585 And she became Dilma Rousseff, 0:07:19.609,0:07:23.789 the president-elect of one of the biggest[br]democracies in the world, 0:07:23.813,0:07:27.021 moving from minister[br]of energy to president. 0:07:27.045,0:07:30.926 If you have democracy,[br]people will vote for washing machines. 0:07:30.950,0:07:32.435 They love them! 0:07:32.459,0:07:33.725 (Laughter) 0:07:34.236,0:07:36.020 And what's the magic with them? 0:07:36.044,0:07:39.276 My mother explained[br]the magic with this machine 0:07:39.300,0:07:41.777 the very, very first day. 0:07:41.801,0:07:43.311 She said, "Now, Hans. 0:07:44.275,0:07:45.760 We have loaded the laundry. 0:07:45.784,0:07:47.501 The machine will make the work. 0:07:47.525,0:07:49.666 And now we can go to the library." 0:07:50.159,0:07:53.100 Because this is the magic:[br]you load the laundry, 0:07:53.124,0:07:55.406 and what do you get out of the machine? 0:07:55.430,0:07:58.731 You get books out of the machines, 0:07:58.755,0:07:59.907 children's books. 0:07:59.931,0:08:02.276 And mother got time to read for me. 0:08:02.300,0:08:03.465 She loved this. 0:08:03.489,0:08:07.276 I got the "ABC's" -- this is why[br]I started my career as a professor, 0:08:07.300,0:08:09.440 when my mother had time to read for me. 0:08:09.464,0:08:11.276 And she also got books for herself. 0:08:11.300,0:08:15.055 She managed to study English[br]and learn that as a foreign language. 0:08:15.079,0:08:17.386 And she read so many novels, 0:08:17.410,0:08:19.850 so many different novels here. 0:08:19.874,0:08:23.540 And we really,[br]we really loved this machine. 0:08:23.564,0:08:24.702 (Laughter) 0:08:24.726,0:08:27.276 And what we said, my mother and me, 0:08:27.300,0:08:29.772 "Thank you, industrialization. 0:08:30.300,0:08:32.234 Thank you, steel mill. 0:08:32.258,0:08:34.052 Thank you, power station. 0:08:34.076,0:08:37.100 And thank you,[br]chemical processing industry 0:08:37.124,0:08:39.132 that gave us time to read books." 0:08:39.156,0:08:40.373 Thank you very much. 0:08:40.397,0:08:41.479 (Laughter) 0:08:41.503,0:08:48.503 (Applause)
