0:00:08.420,0:00:09.850 Thank you very much. 0:00:10.460,0:00:11.525 When I was a boy, 0:00:11.525,0:00:15.310 my parents would sometimes[br]take me camping in California. 0:00:15.430,0:00:19.080 We would camp in the beaches,[br]in the forests, in the deserts. 0:00:19.590,0:00:22.080 Some people think the deserts[br]are empty of life 0:00:22.080,0:00:25.390 but my parents taught me[br]to see the wildlife all around us: 0:00:25.439,0:00:29.040 the hawks, the eagles, the tortoises. 0:00:29.170,0:00:31.410 One time when we were setting up camp, 0:00:31.410,0:00:34.510 we found a baby scorpion[br]with its stinger out, 0:00:34.510,0:00:36.849 and I remember thinking how cool it was 0:00:36.849,0:00:40.240 that something could be[br]both so cute and also so dangerous. 0:00:41.650,0:00:43.720 After college, I moved to California 0:00:43.720,0:00:46.490 and I started working on a number[br]of environmental campaigns, 0:00:46.490,0:00:50.500 I got involved in helping to save[br]the state's last ancient redwood forests 0:00:50.500,0:00:55.590 and blocking a proposed radioactive[br]waste repository set for the desert. 0:00:55.590,0:00:56.890 Shortly after I turned 30, 0:00:56.890,0:01:00.410 I decided I wanted to dedicate[br]a significant amount of my life 0:01:00.410,0:01:02.010 to solving climate change. 0:01:02.190,0:01:05.589 I was worried that global warming[br]would end up destroying 0:01:05.660,0:01:07.345 many of the natural environments 0:01:07.345,0:01:09.730 that people had worked[br]so hard to protect. 0:01:10.170,0:01:13.180 I thought the technical solutions[br]were pretty straightforward; 0:01:13.180,0:01:16.060 solar panels on every roof,[br]electric car in the driveway, 0:01:16.060,0:01:18.820 that the main obstacles were political. 0:01:18.820,0:01:21.300 And so I helped to organize a coalition 0:01:21.300,0:01:25.470 of the country's biggest labor unions[br]and biggest environmental groups. 0:01:25.470,0:01:30.090 Our proposal was for a 300 billion[br]dollar investment in renewables. 0:01:30.090,0:01:33.200 And the idea was not only[br]would we prevent climate change, 0:01:33.200,0:01:35.795 but we would also create[br]millions of new jobs 0:01:35.795,0:01:38.440 in a very fast-growing high-tech sector. 0:01:38.770,0:01:41.629 Our efforts really paid off in 2007, 0:01:41.629,0:01:45.500 when then-presidential candidate[br]Barack Obama embraced our vision. 0:01:45.500,0:01:51.319 And between 2009 and 2015,[br]the US invested 150 billion dollars 0:01:51.319,0:01:54.040 in renewables and other[br]kinds of clean tech. 0:01:54.810,0:01:57.960 but right away we started[br]to encounter some problems. 0:01:57.960,0:02:00.819 So first of all, the electricity[br]from solar rooftops 0:02:00.819,0:02:04.679 ends up costing about twice as much[br]as the electricity from solar farms. 0:02:04.929,0:02:08.389 And both solar farms and wind farms[br]require covering a pretty significant 0:02:08.389,0:02:11.590 amount of land with solar panels[br]and wind turbines 0:02:11.590,0:02:14.590 and also building[br]very big transmission lines 0:02:14.590,0:02:17.780 to bring all that electricity[br]from the countryside into the city. 0:02:18.100,0:02:22.990 Both of those things were often very[br]strongly resisted by local communities, 0:02:22.990,0:02:25.205 as well as by conservation biologists 0:02:25.205,0:02:30.120 who were concerned about the impacts[br]on wild bird species and other animals. 0:02:30.600,0:02:32.780 Now, there was a lot of other people 0:02:32.780,0:02:35.070 working on technical[br]solutions at the time. 0:02:35.070,0:02:36.990 One of the big challenges, of course, 0:02:36.990,0:02:39.000 is just the intermittency[br]of solar and wind 0:02:39.000,0:02:41.770 they only generate electricity[br]about 10 to 30 percent of the time 0:02:41.770,0:02:43.560 during most of year. 0:02:43.560,0:02:45.985 But some of the solutions[br]that were being proposed 0:02:45.985,0:02:50.430 were to convert hydroelectric[br]dams into gigantic batteries. 0:02:50.459,0:02:51.624 The idea was that 0:02:51.624,0:02:53.630 when the sun was shining[br]and the wind was blowing, 0:02:53.630,0:02:56.230 you would pump[br]the water uphill, store it for later 0:02:56.230,0:02:59.700 and then when you needed electricity,[br]run it over the turbines. 0:03:00.630,0:03:02.029 In terms of wildlife, 0:03:02.029,0:03:04.799 some of these problems just didn't[br]seem like a significant concern. 0:03:04.799,0:03:08.980 So when I learned that house cats[br]kill billions of birds every year 0:03:09.010,0:03:12.155 it put into perspective the hundreds[br]of thousands of birds 0:03:12.155,0:03:14.230 that are killed by wind turbines. 0:03:14.630,0:03:16.500 It basically seemed to me at the time 0:03:16.500,0:03:20.450 that most, if not all, of the problems[br]of scaling up solar and wind 0:03:20.450,0:03:23.450 could be solved through more[br]technological innovation. 0:03:24.190,0:03:25.979 But as the years went by, 0:03:25.979,0:03:29.604 these problems persisted[br]and, in many cases, grew worse. 0:03:30.010,0:03:33.070 So California is a state that's really[br]committed to renewable energy, 0:03:33.330,0:03:36.594 but we still haven't converted[br]many of our hydroelectric dams 0:03:36.594,0:03:37.859 into big batteries. 0:03:37.859,0:03:40.630 Some of the problems are just Geographic; 0:03:40.630,0:03:43.540 it's just you have to have[br]a very particular kind of formation 0:03:43.710,0:03:44.939 to be able to do that, 0:03:44.939,0:03:46.280 and even in those cases, 0:03:46.280,0:03:49.019 it's quite expensive[br]to make those conversions. 0:03:49.019,0:03:52.389 Other challenges are just[br]that there're other uses for water 0:03:52.389,0:03:53.910 like irrigation, 0:03:53.910,0:03:58.419 and maybe the most significant[br]problem is just that in California, 0:03:58.419,0:04:00.814 the water in our rivers and reservoirs 0:04:00.814,0:04:03.210 is growing increasingly[br]scarce and unreliable 0:04:03.210,0:04:05.170 due to climate change. 0:04:05.170,0:04:09.610 In terms of this issue of reliability[br]as a consequence of it, 0:04:09.610,0:04:14.280 we've actually had to stop the electricity[br]coming from the solar farms into the cities 0:04:14.410,0:04:16.730 because there's just been[br]too much of it at times. 0:04:16.730,0:04:20.289 Or we've been starting to pay[br]our neighboring states like Arizona 0:04:20.328,0:04:22.659 to take that solar electricity. 0:04:22.659,0:04:25.529 The alternative is to suffer[br]from blowouts of the grid. 0:04:25.529,0:04:27.760 And it turns out that 0:04:27.760,0:04:30.730 when it comes to birds and cats - 0:04:31.450,0:04:35.440 cats don't kill eagles; eagles kill cats. 0:04:35.440,0:04:40.690 What cats kill are the small common[br]sparrows and Jay's and robins, 0:04:40.690,0:04:44.700 birds that are not endangered[br]and not at risk of going extinct. 0:04:45.040,0:04:51.185 What do kill eagles and other big birds[br]like this kite as well as owls and condors 0:04:51.185,0:04:53.890 and other threatened[br]and endangered species 0:04:53.890,0:04:54.990 are wind turbines- 0:04:54.990,0:04:59.980 in fact, one of the most significant threats[br]to those big bird species that we have - 0:05:00.910,0:05:03.160 we just haven't been introducing[br]the airspace with many other objects 0:05:03.160,0:05:05.320 like we have wind turbines 0:05:05.320,0:05:07.540 over the last several years. 0:05:07.540,0:05:09.840 And in terms of solar, 0:05:09.840,0:05:13.150 you know building a solar farm[br]is a lot like building any other kind of farm 0:05:13.150,0:05:16.090 You have to clear[br]the whole area of wildlife. 0:05:16.420,0:05:17.417 So this is a picture of one third of one[br]of the biggest solar farms in California 0:05:17.417,0:05:18.415 called Ivanpah. 0:05:22.000,0:05:24.370 In order to build this, 0:05:24.370,0:05:26.380 they had to clear[br]the whole area of desert tortoises - 0:05:28.180,0:05:30.730 literally pulling desert tortoises - 0:05:30.730,0:05:32.530 and their babies out of burrows 0:05:32.530,0:05:34.270 putting them on the back of pickup trucks,[br]and transporting them to captivity 0:05:34.270,0:05:36.610 where many of them ended up dying. 0:05:38.500,0:05:41.020 And currently, the current estimates are[br]that about 6,000 birds are killed every year, 0:05:41.020,0:05:43.060 actually catching on fire above the solar farm[br]and plunging to their deaths. 0:05:47.890,0:05:49.060 Over time it gradually struck me 0:05:49.060,0:05:50.230 that there was really no amount[br]of technological innovation 0:05:52.270,0:05:54.610 that was going to make[br]the sunshine more regularly 0:05:54.610,0:05:57.790 or wind blow more reliably. 0:05:57.790,0:05:59.860 In fact, nothing could you could make solar 0:05:59.860,0:06:01.720 panels cheaper you could make wind 0:06:01.720,0:06:03.940 turbines bigger but sunlight and wind 0:06:03.940,0:06:06.490 are just really dilute fuels and in 0:06:06.490,0:06:08.470 order to produce significant amounts of 0:06:08.470,0:06:09.100 electricity 0:06:09.100,0:06:11.650 you just have to cover a very large land 0:06:11.650,0:06:15.010 mass with them in other words all of the 0:06:15.010,0:06:17.170 major problems with renewables aren't 0:06:17.170,0:06:20.320 technical they're natural well dealing 0:06:20.320,0:06:22.630 with all of this unreliability and the 0:06:22.630,0:06:24.280 big environmental impacts obviously 0:06:24.280,0:06:27.070 comes at a pretty high economic cost you 0:06:27.070,0:06:28.210 know we've been hearing a lot about how 0:06:28.210,0:06:29.980 solar panels and wind turbines have come 0:06:29.980,0:06:32.440 down in cost in recent years but that 0:06:32.440,0:06:34.840 cost has been significantly outweighed 0:06:34.840,0:06:37.090 by just the challenges of integrating 0:06:37.090,0:06:39.280 all of that unreliable power onto the 0:06:39.280,0:06:41.140 grid just take for instance what's 0:06:41.140,0:06:41.680 happening 0:06:41.680,0:06:43.990 or Nia at the period in which solar 0:06:43.990,0:06:45.940 panels have come down in price very 0:06:45.940,0:06:48.130 significantly same with wind we've seen 0:06:48.130,0:06:50.500 our electricity prices go up five times 0:06:50.500,0:06:52.449 more than the rest of the country and 0:06:52.449,0:06:54.729 it's not unique to us you can see the 0:06:54.729,0:06:56.530 same phenomenon happened in Germany 0:06:56.530,0:06:58.360 which is really the world's leader in 0:06:58.360,0:06:59.590 solar wind and other renewable 0:06:59.590,0:07:02.800 technologies their prices increased 50 0:07:02.800,0:07:04.630 percent during their big renewable 0:07:04.630,0:07:06.960 energy push now you might think well 0:07:06.960,0:07:08.800 dealing with climate change is just 0:07:08.800,0:07:10.690 going to require that we all pay more 0:07:10.690,0:07:12.910 for energy that's what I used to think 0:07:12.910,0:07:16.060 but consider the case of France France 0:07:16.060,0:07:18.250 actually gets twice as much of its 0:07:18.250,0:07:20.349 electricity from clean zero emission 0:07:20.349,0:07:23.410 sources than does Germany and yet France 0:07:23.410,0:07:25.990 pays half as much almost half as much 0:07:25.990,0:07:29.050 for its electricity how can that be well 0:07:29.050,0:07:30.370 you might have already anticipated the 0:07:30.370,0:07:32.050 answer France gets most of its 0:07:32.050,0:07:33.789 electricity from nuclear power 0:07:33.789,0:07:37.090 about 75% in total and nuclear just ends 0:07:37.090,0:07:39.370 up being a lot more reliable generating 0:07:39.370,0:07:41.620 power 24 hours a day seven days a week 0:07:41.620,0:07:45.160 for about 90% of the year we see this 0:07:45.160,0:07:47.620 phenomenon show up at a global level so 0:07:47.620,0:07:49.090 for example there's been a natural 0:07:49.090,0:07:51.460 experiment over the last 40 years even 0:07:51.460,0:07:52.960 more than that or in terms of the 0:07:52.960,0:07:54.639 deployment of nuclear and the deployment 0:07:54.639,0:07:58.419 of solar you can see that at a little 0:07:58.419,0:08:00.460 bit higher cost we got about half as 0:08:00.460,0:08:02.169 much electricity from solar and wind 0:08:02.169,0:08:06.639 than we did from nuclear well what does 0:08:06.639,0:08:08.830 all this mean for going forward I think 0:08:08.830,0:08:10.840 one of the most significant findings to 0:08:10.840,0:08:13.659 date is this one had Germany spent five 0:08:13.659,0:08:15.280 hundred eighty billion dollars on 0:08:15.280,0:08:17.470 nuclear instead of renewables it would 0:08:17.470,0:08:19.509 already be getting a hundred percent of 0:08:19.509,0:08:21.099 its end of its electricity from clean 0:08:21.099,0:08:23.530 energy sources and all of its 0:08:23.530,0:08:26.409 transportation energy now I think you 0:08:26.409,0:08:27.520 might be wondering and it's quite 0:08:27.520,0:08:30.009 reasonable to ask is nuclear power safe 0:08:30.009,0:08:32.469 and what do you do with the waste well 0:08:32.469,0:08:33.969 those are very reasonable questions 0:08:33.969,0:08:36.070 turns out that there's been scientific 0:08:36.070,0:08:38.770 studies on this going over 40 years this 0:08:38.770,0:08:40.240 is just the most recent study that was 0:08:40.240,0:08:42.250 done by the prestigious British Medical 0:08:42.250,0:08:44.260 Journal Lancet finds that nuclear power 0:08:44.260,0:08:46.930 is the safest it's easy to understand 0:08:46.930,0:08:48.640 why according to the World Health 0:08:48.640,0:08:51.040 Organization about 7 million people die 0:08:51.040,0:08:53.500 annually from air pollution and nuclear 0:08:53.500,0:08:55.570 plants don't emit that as a result the 0:08:55.570,0:08:57.430 climate scientist James Hansen looked at 0:08:57.430,0:08:59.350 and he calculated that nuclear power has 0:08:59.350,0:09:01.750 already saved almost two million lives 0:09:01.750,0:09:04.210 to date it turns out that even wind 0:09:04.210,0:09:07.120 energy is more deadly than nuclear this 0:09:07.120,0:09:09.790 is a photograph taken of two maintenance 0:09:09.790,0:09:11.500 workers in the Netherlands 0:09:11.500,0:09:13.630 shortly before one of them fell to his 0:09:13.630,0:09:15.640 death to avoid the fire and the other 0:09:15.640,0:09:17.260 one was engulfed in flames 0:09:17.260,0:09:20.440 now what about environmental impact well 0:09:20.440,0:09:21.760 I think a really easy way to think about 0:09:21.760,0:09:24.070 it is that uranium fuel which is what we 0:09:24.070,0:09:25.930 use to power nuclear plants is just 0:09:25.930,0:09:28.210 really energy dense about his mouth 0:09:28.210,0:09:30.340 about the same amount of uranium as this 0:09:30.340,0:09:32.890 is this Rubik's Cube can power all of 0:09:32.890,0:09:34.660 the energy that you need in your entire 0:09:34.660,0:09:35.440 life 0:09:35.440,0:09:38.680 as a consequence you just don't need 0:09:38.680,0:09:40.600 that much land in order to produce a 0:09:40.600,0:09:42.880 significant amount of electricity here 0:09:42.880,0:09:44.830 you can compare the solar farm I just 0:09:44.830,0:09:47.410 described Ivanpah to California's last 0:09:47.410,0:09:50.770 nuclear plant Diablo Canyon it takes 450 0:09:50.770,0:09:52.750 times more land to generate the same 0:09:52.750,0:09:54.790 amount of electricity as it does from 0:09:54.790,0:09:57.430 nuclear you would need 17 more solar 0:09:57.430,0:09:59.920 farms like Ivanpah in order to generate 0:09:59.920,0:10:02.320 the same output as Diablo Canyon and of 0:10:02.320,0:10:05.800 course it would then be unreliable well 0:10:05.800,0:10:07.960 what about the mining and the waste and 0:10:07.960,0:10:10.120 the material throughput well this has 0:10:10.120,0:10:11.920 been studied pretty closely as well and 0:10:11.920,0:10:13.510 it just turns out that solar panels 0:10:13.510,0:10:16.270 require 17 times more materials than 0:10:16.270,0:10:18.610 nuclear plants do in the form of cement 0:10:18.610,0:10:21.490 glass concrete steel and that includes 0:10:21.490,0:10:23.230 all the fuel used for those nuclear 0:10:23.230,0:10:25.480 plants the consequence is that what 0:10:25.480,0:10:27.730 comes out at the end since its material 0:10:27.730,0:10:30.160 throughput is just not a lot of waste 0:10:30.160,0:10:32.560 from nuclear all of the waste from the 0:10:32.560,0:10:34.570 Swiss nuclear program fits into this 0:10:34.570,0:10:37.000 room nuclear waste is actually the only 0:10:37.000,0:10:38.950 waste from electricity production 0:10:38.950,0:10:41.230 that's safely contained and internalized 0:10:41.230,0:10:43.210 every other way of making electricity 0:10:43.210,0:10:45.490 emits that waste into the natural 0:10:45.490,0:10:48.010 environment either as pollution or as 0:10:48.010,0:10:50.589 material waste we tend to think of solar 0:10:50.589,0:10:53.410 panels as clean but the truth is is that 0:10:53.410,0:10:55.270 there is no plan to deal with solar 0:10:55.270,0:10:57.790 panels at the end of their 20 or 25 year 0:10:57.790,0:11:00.220 life a lot of experts are actually very 0:11:00.220,0:11:02.440 concerned that solar panels are just 0:11:02.440,0:11:04.180 going to be shipped to poor countries in 0:11:04.180,0:11:06.459 Africa or Asia with the rest of our 0:11:06.459,0:11:07.270 electronic way 0:11:07.270,0:11:10.780 stream to be disassembled often exposing 0:11:10.780,0:11:13.210 people to really high levels of toxic of 0:11:13.210,0:11:15.610 toxic elements including lead cadmium 0:11:15.610,0:11:17.980 and chromium elements that because their 0:11:17.980,0:11:20.680 elements their toxicity never declines 0:11:20.680,0:11:23.200 over time I think we have an intuitive 0:11:23.200,0:11:25.660 sense that nuclear is a really powerful 0:11:25.660,0:11:28.360 strong energy source and that sunlight 0:11:28.360,0:11:31.150 is really dilute and diffuse and weak 0:11:31.150,0:11:33.430 which is why you have to spread solar 0:11:33.430,0:11:35.290 collectors or wind collectors over such 0:11:35.290,0:11:38.320 a large amount of land maybe that's why 0:11:38.320,0:11:40.750 nobody was surprised when in the recent 0:11:40.750,0:11:43.150 science-fiction remake of Blade Runner 0:11:43.150,0:11:45.910 the film opens a very dark dystopian 0:11:45.910,0:11:48.340 scene where California's deserts have 0:11:48.340,0:11:52.480 been entirely paved with solar farms all 0:11:52.480,0:11:53.860 of which I think raises a really 0:11:53.860,0:11:56.740 uncomfortable question in the effort to 0:11:56.740,0:11:59.020 try to save the climate are we 0:11:59.020,0:12:02.290 destroying the environment well the 0:12:02.290,0:12:03.910 interesting thing is that over the last 0:12:03.910,0:12:05.710 several hundred years human beings have 0:12:05.710,0:12:07.030 actually been trying to move away from 0:12:07.030,0:12:08.860 what you would consider matter dense 0:12:08.860,0:12:11.710 fuels towards energy dense ones that 0:12:11.710,0:12:14.140 means really from wood and dung towards 0:12:14.140,0:12:16.990 coal oil natural gas uranium this is a 0:12:16.990,0:12:18.310 phenomenon that's been going on for a 0:12:18.310,0:12:20.230 long time poor countries around the 0:12:20.230,0:12:22.090 world are in the process still of moving 0:12:22.090,0:12:23.620 away from wood and dung as their primary 0:12:23.620,0:12:26.500 energies and for the most part this is a 0:12:26.500,0:12:29.980 positive thing as you stop using wood as 0:12:29.980,0:12:32.050 your major source of fuel it allows the 0:12:32.050,0:12:34.510 forests to grow back and the wildlife to 0:12:34.510,0:12:36.340 return as you stop burning wood in your 0:12:36.340,0:12:38.410 home you don't you no longer need to 0:12:38.410,0:12:40.990 breathe that toxic smoke and as you go 0:12:40.990,0:12:43.750 from coal to natural gas and uranium is 0:12:43.750,0:12:45.790 your main sources of energy it holds out 0:12:45.790,0:12:48.130 the possibility of basically eliminating 0:12:48.130,0:12:50.830 air pollution altogether there's just 0:12:50.830,0:12:53.050 this problem with nuclear well it's been 0:12:53.050,0:12:55.240 pretty popular to move from dirtier to 0:12:55.240,0:12:56.890 cleaner energy sources from energy 0:12:56.890,0:12:59.890 diffuse to energy dense sources nuclear 0:12:59.890,0:13:02.230 is just really unpopular for a bunch of 0:13:02.230,0:13:04.780 historical reasons and as a consequence 0:13:04.780,0:13:07.450 in the past I and I think a lot of 0:13:07.450,0:13:09.520 others have sort of said well in order 0:13:09.520,0:13:11.170 to deal with climate change we're just 0:13:11.170,0:13:12.850 going to need all the different kinds of 0:13:12.850,0:13:15.490 clean energy that we have the problem is 0:13:15.490,0:13:16.990 is that just turns out not to be true 0:13:16.990,0:13:19.600 you remember I discussed France a little 0:13:19.600,0:13:20.920 bit ago France 0:13:20.920,0:13:22.240 gets most of its electricity from 0:13:22.240,0:13:24.430 nuclear if France were to try to 0:13:24.430,0:13:27.339 significantly scale up solar and wind it 0:13:27.339,0:13:29.170 would also have to significantly reduce 0:13:29.170,0:13:31.029 how much electricity it gets from 0:13:31.029,0:13:32.980 nuclear that's because in order to 0:13:32.980,0:13:35.980 handle the huge variability of solar and 0:13:35.980,0:13:38.079 wind on the grid they would need to burn 0:13:38.079,0:13:40.120 more natural gas think of it this way 0:13:40.120,0:13:42.250 it's just really hard to ramp up and 0:13:42.250,0:13:44.139 down a nuclear plant whereas I think 0:13:44.139,0:13:45.790 we're all pretty familiar with turning 0:13:45.790,0:13:47.829 the natural gas up and down on our stove 0:13:47.829,0:13:50.350 a similar process works in managing the 0:13:50.350,0:13:52.930 grid of course goes without saying that 0:13:52.930,0:13:55.240 oil and gas companies understand this 0:13:55.240,0:13:57.310 pretty well which is why we've seen them 0:13:57.310,0:13:59.350 invest millions of dollars in recent 0:13:59.350,0:14:03.250 years in promoting solar and wind this 0:14:03.250,0:14:05.500 just raises I think another challenging 0:14:05.500,0:14:07.990 question which is that in places that 0:14:07.990,0:14:10.360 are using a lot of nuclear have grids 0:14:10.360,0:14:14.170 that are mostly nuclear and hydro going 0:14:14.170,0:14:15.639 towards solar and wind and other 0:14:15.639,0:14:17.620 renewables would actually increase 0:14:17.620,0:14:19.930 carbon emissions I think a better 0:14:19.930,0:14:21.519 alternative is just to tell the truth 0:14:21.519,0:14:23.380 and that's what a number of scientists 0:14:23.380,0:14:25.620 have been doing I mentioned earlier that 0:14:25.620,0:14:27.730 hundreds of thousands of birds are 0:14:27.730,0:14:29.380 killed every year by wind turbines but I 0:14:29.380,0:14:31.899 didn't mention is that a million bats at 0:14:31.899,0:14:33.880 a minimum are killed every year by wind 0:14:33.880,0:14:35.829 the consequence has been that bad 0:14:35.829,0:14:37.480 scientists have been speaking out about 0:14:37.480,0:14:40.209 this this particular bat species the 0:14:40.209,0:14:42.339 hoary bat which is a migratory bat 0:14:42.339,0:14:44.649 species is literally at risk of going 0:14:44.649,0:14:46.449 extinct right now because of the 0:14:46.449,0:14:48.940 significant expansion of wind it's not 0:14:48.940,0:14:51.640 just wind it's also on solar the 0:14:51.640,0:14:53.529 scientists who were involved in creating 0:14:53.529,0:14:55.959 the Ivanpah solar farm who involved in 0:14:55.959,0:14:58.149 clearing that land have been speaking 0:14:58.149,0:15:01.120 out one of them wrote everybody knows 0:15:01.120,0:15:03.399 that translocation of desert tortoises 0:15:03.399,0:15:05.290 doesn't work when you're walking in 0:15:05.290,0:15:07.089 front of a bulldozer or crying and 0:15:07.089,0:15:09.160 moving animals and cacti out of the way 0:15:09.160,0:15:11.199 it's hard to think that the project is a 0:15:11.199,0:15:13.480 good idea and now we can see these 0:15:13.480,0:15:16.540 phenomena at work at an international 0:15:16.540,0:15:18.370 level in my home state of California 0:15:18.370,0:15:20.410 we've been stuffing a lot of natural gas 0:15:20.410,0:15:22.329 into the side of a mountain in order to 0:15:22.329,0:15:23.860 handle all that intermittent solar and 0:15:23.860,0:15:24.250 wind 0:15:24.250,0:15:26.230 it's sprung a leak it was equivalent to 0:15:26.230,0:15:28.300 putting 500,000 cars on the road and 0:15:28.300,0:15:30.640 currently in Germany there's protesters 0:15:30.640,0:15:33.220 trying to block a new coal mining 0:15:33.220,0:15:34.320 project 0:15:34.320,0:15:36.240 that would involve destroying the 0:15:36.240,0:15:38.730 ancient Han back forest in order to get 0:15:38.730,0:15:41.100 to the coal underneath all in an effort 0:15:41.100,0:15:43.440 to phase out nuclear and expand solar 0:15:43.440,0:15:46.380 and wind the good news is is that I 0:15:46.380,0:15:48.510 think that people still care about 0:15:48.510,0:15:50.310 nature enough for these facts to matter 0:15:50.310,0:15:52.770 we saw last year in South Korea a 0:15:52.770,0:15:55.110 citizen's jury deliberated for several 0:15:55.110,0:15:56.880 months weighing these different issues 0:15:56.880,0:15:58.890 they had to decide whether they were 0:15:58.890,0:16:01.650 going to phase out nuclear or keep it 0:16:01.650,0:16:04.140 and expanded they started out 40 percent 0:16:04.140,0:16:06.540 in favor of expanding nuclear but after 0:16:06.540,0:16:08.040 several months and considering these 0:16:08.040,0:16:10.320 issues they ended up voting 60 percent 0:16:10.320,0:16:13.020 to expand nuclear a similar phenomena 0:16:13.020,0:16:15.120 just happened last week in Arizona the 0:16:15.120,0:16:17.100 voters had a ballot initiative that to 0:16:17.100,0:16:19.200 vote on whether or not to continue with 0:16:19.200,0:16:21.150 nuclear or to phase it out and try to 0:16:21.150,0:16:23.220 replace it with natural gas and solar 0:16:23.220,0:16:26.160 they ended up rejecting at 70 to 30 and 0:16:26.160,0:16:28.500 even here in Europe we saw the 0:16:28.500,0:16:30.150 Netherlands is that one of the first 0:16:30.150,0:16:32.700 countries in recent memory to actually 0:16:32.700,0:16:34.740 announce as they did last week that 0:16:34.740,0:16:36.360 they're going to start to they're gonna 0:16:36.360,0:16:37.890 start to increase their reliance on 0:16:37.890,0:16:39.810 nuclear power in recognition that 0:16:39.810,0:16:41.250 there's just no way they could generate 0:16:41.250,0:16:43.110 significant amounts of energy enough 0:16:43.110,0:16:44.970 from solar and wind to meet their 0:16:44.970,0:16:47.370 climate targets I think it's natural 0:16:47.370,0:16:49.560 that those of us that became very 0:16:49.560,0:16:51.210 concerned about climate change such a 0:16:51.210,0:16:53.310 big environmental issue would gravitate 0:16:53.310,0:16:56.540 towards really romantic solutions like 0:16:56.540,0:16:58.980 harmonizing human civilization with the 0:16:58.980,0:17:01.140 natural world using renewable energies 0:17:01.140,0:17:03.090 but I think it's also understandable 0:17:03.090,0:17:05.849 that as the facts have come in that many 0:17:05.849,0:17:07.650 of us have started to question our prior 0:17:07.650,0:17:10.410 beliefs and change our minds for me the 0:17:10.410,0:17:14.030 question now is now that we know that 0:17:14.030,0:17:16.859 renewables can't save the planet are we 0:17:16.859,0:17:18.660 going to keep letting them destroy it 0:17:18.660,0:17:25.510 thank you very much
