We need nuclear power to solve climate change

  • 0:03 - 0:04
    It's easy to forget that last night,
  • 0:04 - 0:08
    one billion people went to sleep
    without access to electricity.
  • 0:08 - 0:11
    One billion people.
  • 0:11 - 0:14
    Two and a half billion people
    did not have access
  • 0:14 - 0:16
    to clean cooking fuels
  • 0:16 - 0:18
    or clean heating fuels.
  • 0:18 - 0:21
    Those are the problems
    in the developing world,
  • 0:21 - 0:24
    and it's easy for us not to be
    empathetic with those people
  • 0:24 - 0:26
    who seem so distant from us.
  • 0:26 - 0:30
    But even in our own world,
    the developed world,
  • 0:30 - 0:33
    we see the tension of stagnant economies
  • 0:33 - 0:36
    impacting the lives of people around us.
  • 0:36 - 0:40
    We see it in whole pieces of the economy,
  • 0:40 - 0:43
    where the people involved
    have lost hope about the future
  • 0:43 - 0:46
    and despair about the present.
  • 0:46 - 0:48
    We see that in the Brexit vote.
  • 0:48 - 0:51
    We see that in the Sanders/Trump
    campaigns in my own country.
  • 0:51 - 0:57
    But even in countries as recently
    turning the corner
  • 0:57 - 0:59
    towards being in the developed world,
  • 0:59 - 1:00
    in China,
  • 1:00 - 1:02
    we see the difficulty
    that President Xi has
  • 1:02 - 1:08
    as he begins to unemploy so many people
    in his coal and mining industries
  • 1:08 - 1:11
    who see no future for themselves.
  • 1:11 - 1:14
    As we as a society figure out
    how to manage
  • 1:14 - 1:16
    the problems of the developed world
  • 1:16 - 1:18
    and the problems of the developing world,
  • 1:18 - 1:21
    we have to look at how we move forward
  • 1:21 - 1:24
    and manage the environmental impact
  • 1:24 - 1:26
    of those decisions.
  • 1:26 - 1:28
    We've been working on this problem
    for 25 years, since Rio,
  • 1:28 - 1:31
    the Kyoto Protocols.
  • 1:31 - 1:33
    Our most recent move
  • 1:33 - 1:35
    is the Paris treaty,
  • 1:35 - 1:37
    and the resulting climate agreements
  • 1:37 - 1:40
    that are being ratified
    by nations around the world.
  • 1:40 - 1:42
    I think we can be very hopeful
  • 1:42 - 1:46
    that those agreements,
    which are bottom-up agreements,
  • 1:46 - 1:48
    where nations have said
    what they think they can do,
  • 1:48 - 1:53
    are genuine and forthcoming
    for the vast majority of the parties.
  • 1:53 - 1:55
    The unfortunate thing
  • 1:55 - 2:00
    is that now, as we look
    at the independent analyses
  • 2:00 - 2:03
    of what those climate treaties
    are liable to yield,
  • 2:03 - 2:07
    the magnitude of the problem
    before us becomes clear.
  • 2:07 - 2:12
    This is the United States
    Energy Information Agency's assessment
  • 2:12 - 2:13
    of what will happen
  • 2:13 - 2:16
    if the countries implement
    the climate commitments
  • 2:16 - 2:18
    that they've made in Paris
  • 2:18 - 2:21
    between now and 2040.
  • 2:21 - 2:26
    It shows basically CO2 emissions
    around the world
  • 2:26 - 2:28
    over the next 30 years.
  • 2:28 - 2:31
    There are three things
    that you need to look at
  • 2:31 - 2:32
    and appreciate.
  • 2:32 - 2:37
    One, CO2 emissions are expected
    to continue to grow
  • 2:37 - 2:39
    for the next 30 years.
  • 2:39 - 2:42
    In order to control climate,
  • 2:42 - 2:46
    CO2 emissions have to literally go to zero
  • 2:46 - 2:50
    because it's the cumulative emissions
    that drive heating on the planet.
  • 2:50 - 2:55
    This should tell you that we are losing
    the race to fossil fuels.
  • 2:56 - 2:58
    The second thing you should notice
  • 2:58 - 3:00
    is that the bulk of the growth
  • 3:00 - 3:02
    comes from the developing countries,
  • 3:02 - 3:04
    from China, from India,
  • 3:04 - 3:05
    from the rest of the world,
  • 3:05 - 3:09
    which includes South Africa
    and Indonesia and Brazil,
  • 3:09 - 3:12
    as most of these countries
    move their people
  • 3:12 - 3:15
    into the lower range of lifestyles
  • 3:15 - 3:18
    that we literally take for granted
  • 3:18 - 3:20
    in the developed world.
  • 3:20 - 3:23
    The final thing that you should notice
  • 3:23 - 3:25
    is that each year,
  • 3:25 - 3:30
    about 10 gigatons of carbon
    are getting added
  • 3:30 - 3:33
    to the planet's atmosphere,
  • 3:33 - 3:36
    and then diffusing into the ocean
    and into the land.
  • 3:36 - 3:42
    That's on top of the 550 gigatons
    that are in place today.
  • 3:42 - 3:44
    At the end of 30 years,
  • 3:44 - 3:46
    we will have put 850 gigatons
  • 3:46 - 3:49
    of carbon into the air,
  • 3:49 - 3:52
    and that probably goes a long way
  • 3:52 - 3:56
    towards locking in
    a 2-4 degree C increase
  • 3:56 - 3:58
    in global mean surface temperatures,
  • 3:58 - 4:01
    locking in ocean acidification,
  • 4:01 - 4:04
    and locking in sea level rise.
  • 4:04 - 4:06
    Now, this is a projection
  • 4:06 - 4:08
    made by men
  • 4:08 - 4:11
    by the actions of society,
  • 4:11 - 4:14
    and it's ours to change, not to accept.
  • 4:14 - 4:19
    But the magnitude of the problem
    is something we need to appreciate.
  • 4:19 - 4:21
    Different nations make
    different energy choices.
  • 4:21 - 4:24
    It's a function
    of their natural resources.
  • 4:24 - 4:25
    It's a function of their climate.
  • 4:25 - 4:31
    It's a function of the development path
    that they've followed as a society.
  • 4:31 - 4:34
    It's a function of where
    on the surface of the planet they are.
  • 4:34 - 4:37
    Are they where it's dark
    a lot of the time,
  • 4:37 - 4:39
    or are they at the mid-latitudes?
  • 4:39 - 4:41
    Many, many, many things
  • 4:41 - 4:43
    go into the choices of countries,
  • 4:43 - 4:46
    and they each make a different choice.
  • 4:46 - 4:50
    The overwhelming thing
    that we need to appreciate
  • 4:50 - 4:53
    is the choice that China has made.
  • 4:53 - 4:55
    China has made the choice,
  • 4:55 - 4:58
    and will make the choice, to run on coal.
  • 4:58 - 5:01
    The United States has an alternative.
  • 5:01 - 5:02
    It can run on natural gas
  • 5:02 - 5:06
    as a result of the inventions
    of fracking and shale gas
  • 5:06 - 5:08
    which we have here.
  • 5:08 - 5:09
    They provide an alternative.
  • 5:09 - 5:14
    The OECD Europe has a choice.
  • 5:14 - 5:17
    It has renewables that it can afford
    to deploy in Germany,
  • 5:17 - 5:20
    because it's rich enough
    to afford to do it.
  • 5:20 - 5:26
    The French and the British
    show interest in nuclear power.
  • 5:26 - 5:31
    Eastern Europe, still very heavily
    committed to natural gas and to coal,
  • 5:31 - 5:36
    and with natural gas that comes from
    Russia, with all of its entanglements.
  • 5:36 - 5:38
    China has many fewer choices
  • 5:38 - 5:43
    and a much harder row to hoe.
  • 5:43 - 5:45
    If you look at China,
    and you ask yourself,
  • 5:45 - 5:47
    why has coal been important to it,
  • 5:47 - 5:49
    you have to remember what China's done.
  • 5:49 - 5:53
    China brought people to power,
    not power to people.
  • 5:53 - 5:56
    It didn't do rural electrification.
  • 5:56 - 5:58
    It urbanized.
  • 5:58 - 6:01
    It urbanized by taking low-cost labor
  • 6:01 - 6:02
    and low-cost energy,
  • 6:02 - 6:04
    creating export industries
  • 6:04 - 6:07
    that could fund a tremendous
    amount of growth.
  • 6:07 - 6:10
    If we look at China's path,
  • 6:10 - 6:15
    all of us know that prosperity in China
    has dramatically increased.
  • 6:15 - 6:19
    In 1980, 80 percent of China's population
  • 6:19 - 6:23
    lived below the extreme poverty level,
  • 6:23 - 6:27
    below the level of having
    a $1.90 per person per day.
  • 6:27 - 6:32
    By the year 2000, only 20 percent
    of China's population
  • 6:32 - 6:35
    lived below the extreme poverty level,
  • 6:35 - 6:38
    a remarkable feat,
  • 6:38 - 6:41
    admittedly with some costs
    in civil liberties that would be tough
  • 6:41 - 6:45
    to accept in the Western world.
  • 6:45 - 6:48
    But the impact of all that wealth
  • 6:48 - 6:51
    allowed people to get
    massively better nutrition.
  • 6:51 - 6:54
    It allowed water pipes to be placed.
  • 6:54 - 6:57
    It allowed sewage pipes to be placed,
  • 6:57 - 7:00
    dramatic decrease in diarrheal diseases,
  • 7:00 - 7:04
    at the cost of some outdoor air pollution.
  • 7:04 - 7:06
    But in 1980, and even today,
  • 7:06 - 7:11
    the number one killer in China
    is indoor air pollution,
  • 7:11 - 7:16
    because people do not have access
    to clean cooking and heating fuels.
  • 7:16 - 7:19
    In fact, in 2040,
  • 7:19 - 7:22
    it's still estimated
  • 7:22 - 7:25
    that 200 million people in China
  • 7:25 - 7:27
    will not have access
  • 7:27 - 7:29
    to clean cooking fuels.
  • 7:29 - 7:32
    They have a remarkable path to follow.
  • 7:32 - 7:38
    India also needs to meet the needs
    of its own people,
  • 7:38 - 7:40
    and it's going to do that by burning coal.
  • 7:40 - 7:43
    When we look at the EIA's projections
  • 7:43 - 7:47
    of coal burning in India,
  • 7:47 - 7:50
    India will supply nearly four times
    as much of its energy
  • 7:50 - 7:55
    from coal as it will from renewables.
  • 7:55 - 7:58
    It's not because they don't know
    the alternatives.
  • 7:58 - 8:02
    It's because rich countries
    can do what they choose,
  • 8:02 - 8:06
    poor countries do what they must.
  • 8:06 - 8:11
    So what can we do to stop
    coal's emissions in time?
  • 8:11 - 8:16
    What can we do that changes
    this forecast that's in front of us?
  • 8:16 - 8:18
    Because it's a forecast
    that we can change
  • 8:18 - 8:21
    if we have the will to do it.
  • 8:21 - 8:25
    First of all, we have to think
    about the magnitude of the problem.
  • 8:25 - 8:27
    Between now and 2040,
  • 8:27 - 8:30
    800 to 1,600 new coal plants
  • 8:30 - 8:34
    are going to be built around the world.
  • 8:34 - 8:39
    This week, between one and three
    one gigawatt coal plants
  • 8:39 - 8:42
    are being turned on around the world.
  • 8:42 - 8:46
    That's happening regardless
    of what we want,
  • 8:46 - 8:48
    because the people
    that rule their countries,
  • 8:48 - 8:51
    assessing the interests of their citizens,
  • 8:51 - 8:55
    have decided it's in the interest
    of their citizens to do that.
  • 8:55 - 8:57
    And that's going to happen
  • 8:57 - 9:00
    unless they have a better alternative,
  • 9:00 - 9:02
    and every 100 of those plants
  • 9:02 - 9:05
    will use up between one percent
  • 9:05 - 9:07
    and three percent
  • 9:07 - 9:09
    of the Earth's climate budget.
  • 9:09 - 9:13
    So every day that you go home
    thinking that you should do something
  • 9:13 - 9:14
    about global warming,
  • 9:14 - 9:17
    at the end of that week, remember
  • 9:17 - 9:19
    somebody fired up a coal plant
  • 9:19 - 9:21
    that's going to run for 50 years
  • 9:21 - 9:26
    and take away your ability to change it.
  • 9:26 - 9:28
    What we've forgotten is something
  • 9:28 - 9:31
    that Vinod Khosla used to talk about,
    a man of Indian ethnicity
  • 9:31 - 9:32
    but an American venture capitalist.
  • 9:32 - 9:36
    And he said, back in the early 2000s
  • 9:36 - 9:40
    that if you needed to get China and India
    off of fossil fuels,
  • 9:40 - 9:45
    you had to create a technology
    that passed the Chindia test,
  • 9:45 - 9:48
    Chindia being the appending
    of the two words.
  • 9:48 - 9:50
    It had to be first of all viable,
  • 9:50 - 9:54
    meaning that technically, they could
    implement it in their country,
  • 9:54 - 9:58
    and that it would be accepted
    by the people in the country.
  • 9:58 - 10:02
    Two, it had to be a technology
  • 10:02 - 10:05
    that was scalable,
  • 10:05 - 10:08
    that it could deliver the same benefits
  • 10:08 - 10:11
    on the same timetable as fossil fuels,
  • 10:11 - 10:16
    so that they can enjoy the kind of life,
    again, that we take for granted.
  • 10:16 - 10:18
    And third, it had to be cost-effective
  • 10:18 - 10:21
    without subsidy or without mandate.
  • 10:21 - 10:24
    It had to stand on its own two feet.
  • 10:24 - 10:27
    It could not be maintained
    for that many people
  • 10:27 - 10:31
    if in fact those countries
    had to go begging
  • 10:31 - 10:35
    or had some foreign countries say,
    I won't trade with you,
  • 10:35 - 10:40
    in order to get the technology
    shift to occur.
  • 10:40 - 10:44
    If you look at the Chindia test,
    we simply have not come up
  • 10:44 - 10:47
    with alternatives that meet that test.
  • 10:47 - 10:51
    That's what the EIA forecast tells us.
  • 10:51 - 10:55
    China's building 800 gigawatts of coal,
  • 10:55 - 10:58
    400 gigawatts of hydro,
  • 10:58 - 11:00
    about 200 gigawatts of nuclear,
  • 11:00 - 11:03
    and on an energy equivalent basis,
  • 11:03 - 11:05
    adjusting for intermittency,
  • 11:05 - 11:08
    about 100 gigawatts of renewables.
  • 11:08 - 11:10
    800 gigawatts of coal.
  • 11:10 - 11:13
    They're doing that knowing the costs
    better than any other country,
  • 11:13 - 11:17
    knowing the need better
    than any other country,
  • 11:17 - 11:19
    but that's what they're aiming for in 2040
  • 11:19 - 11:22
    unless we give them a better choice.
  • 11:22 - 11:26
    To give them a better choice, it's
    going to have to meet the Chindia test.
  • 11:26 - 11:29
    If you look at all the alternatives
    that are out there,
  • 11:29 - 11:32
    there are really two
    that come near to meeting it.
  • 11:32 - 11:36
    First is this area of new nuclear
    that I'll talk about in just a second.
  • 11:36 - 11:39
    It's a new generation of nuclear plants
    that are on the drawing boards
  • 11:39 - 11:41
    around the world,
  • 11:41 - 11:43
    and the people who are
    developing these say,
  • 11:43 - 11:47
    we can get them
    in position to demo by 2025
  • 11:47 - 11:51
    and to scale by 2030
    if you will just let us.
  • 11:51 - 11:54
    The second alternative
    that could be there in time
  • 11:54 - 11:57
    is utility-scale solar
  • 11:57 - 11:59
    backed up with natural gas
  • 11:59 - 12:00
    which we can use today
  • 12:00 - 12:05
    versus the batteries
    which are still under development.
  • 12:05 - 12:08
    So what's holding new nuclear back?
  • 12:08 - 12:12
    Outdated regulations
    and yesterday's mindsets.
  • 12:12 - 12:15
    We have not used our latest
    scientific thinking
  • 12:15 - 12:16
    on radiological health
  • 12:16 - 12:19
    to think how we communicate
    with the public
  • 12:19 - 12:22
    and govern the testing
    of new nuclear reactors.
  • 12:22 - 12:24
    We have new scientific knowledge
  • 12:24 - 12:26
    that we need to use
  • 12:26 - 12:28
    in order to improve the way
  • 12:28 - 12:31
    we regulate nuclear industry.
  • 12:31 - 12:33
    The second thing is we've got a mindset
  • 12:33 - 12:36
    that it takes 25 years
    and 2 to 5 billion dollars
  • 12:36 - 12:38
    to develop a nuclear power plant.
  • 12:38 - 12:42
    That comes from the historical,
    military mindset
  • 12:42 - 12:45
    of the places that
    nuclear power came from.
  • 12:45 - 12:48
    These new nuclear ventures are saying
  • 12:48 - 12:52
    that they can deliver power
    for 5 cents per kilowatt/hour,
  • 12:52 - 12:54
    they can deliver it
    for 100 gigawatts a year,
  • 12:54 - 12:57
    they can demo it by 2025,
  • 12:57 - 13:01
    and they can deliver it in scale by 2030,
  • 13:01 - 13:04
    if only we give them a chance.
  • 13:04 - 13:08
    Right now, we're basically
    waiting for a miracle.
  • 13:08 - 13:10
    What we need is a choice.

    If they can't make it safe,
    if they can't make it cheap,
  • 13:13 - 13:15
    it should not be deployed.
  • 13:15 - 13:19
    But what I want you to do
    is not carry an idea forward,
  • 13:19 - 13:21
    but write your leaders,
  • 13:21 - 13:23
    write the head of the NGOs you support,
  • 13:23 - 13:26
    and tell them to give you the choice,
  • 13:26 - 13:27
    not the past.
  • 13:27 - 13:29
    Thank you very much.
  • 13:29 - 13:33
