How to decarbonize the grid and electrify everything
-
0:01 - 0:03John Doerr: Hello, Hal!
-
0:03 - 0:04Hal Harvey: John, nice to see you.
-
0:04 - 0:06JD: Nice to see you too.
-
0:06 - 0:08HH: So John, we've got a big challenge.
-
0:08 - 0:10We need to get carbon
out of the atmosphere. -
0:10 - 0:12We need to stop emitting carbon,
-
0:12 - 0:14drive it to zero by 2050.
-
0:14 - 0:17We need to be halfway there by 2030.
-
0:17 - 0:18Where are we now?
-
0:18 - 0:21JD: As you know,
we're dumping 55 billion tons -
0:21 - 0:25of carbon pollution in our precious
atmosphere every year, -
0:25 - 0:28as if it's some kind
of free and open sewer. -
0:28 - 0:31To get halfway to zero by 2030,
-
0:31 - 0:34we're going to have to reduce
annual emissions -
0:34 - 0:36by about 10 percent a year.
-
0:36 - 0:39And we've never reduced
annual emissions in any year -
0:39 - 0:41in the history of the planet.
-
0:41 - 0:42So let's break this down.
-
0:42 - 0:44Seventy-five percent of the emissions
-
0:44 - 0:47come from the 20 largest
emitting countries. -
0:47 - 0:51And from four sectors of their economy.
-
0:51 - 0:52The first is grid.
-
0:52 - 0:54Second, transportation.
-
0:54 - 0:55The third from the buildings.
-
0:55 - 0:57And the fourth from industrial activities.
-
0:57 - 1:02We've got to fix all those,
at speed and at scale. -
1:02 - 1:05HH: It is now cheaper
to generate electricity -
1:05 - 1:08from clean energy sources
than from dirty energy sources -
1:08 - 1:10to create electricity.
-
1:10 - 1:11And what that does is
-
1:11 - 1:13it means it's possible
to decarbonize the grid, -
1:13 - 1:17and then use that clean electricity
to run everything else in the economy. -
1:17 - 1:20So an electric vehicle
charged off a clean grid -
1:20 - 1:21is a clean vehicle.
-
1:21 - 1:25An electric house run off of a clean grid
is a clean house, and so forth. -
1:25 - 1:27So the shorthand I like to use is,
-
1:27 - 1:30decarbonize the grid
and electrify everything. -
1:30 - 1:32This can happen at a much more rapid pace
-
1:32 - 1:35because of the dramatic
declines in clean energy. -
1:35 - 1:38Solar energy has dropped 80 percent
in price in the last decade, -
1:38 - 1:39and wind has dropped by half.
-
1:39 - 1:44The point is, we have the technologies
for a big step to get this going. -
1:44 - 1:47The concurrent demand means
we have to stop building polluting cars. -
1:47 - 1:50We have to stop creating
more internal combustion engines, -
1:50 - 1:52and more leaky houses,
and more dirty factories. -
1:52 - 1:58Because those are a drag on our ability
to decarbonize the entire economy. -
1:58 - 2:04JD: Well, I think a key question, Hal,
is do we have the technology that we need -
2:04 - 2:07to replace fossil fuels
to get this job done? -
2:07 - 2:08And my answer is no.
-
2:08 - 2:12I think we're about 70,
maybe 80 percent of the way there. -
2:12 - 2:16For example, we urgently need
a breakthrough in batteries. -
2:16 - 2:18Our batteries need to be
higher energy density. -
2:18 - 2:21They need to have enhanced
safety, faster charging. -
2:21 - 2:23They need to take less
space and less weight, -
2:23 - 2:26and above all else,
they need to cost a lot less. -
2:26 - 2:31In fact, we need new chemistries
that don't rely on scarce cobalt. -
2:31 - 2:34And we're going to need
lots of these batteries. -
2:34 - 2:38We desperately need much more research
in clean energy technology. -
2:38 - 2:42The US invests about
2.5 billion dollars a year. -
2:42 - 2:45Do you know how much Americans
spend on potato chips? -
2:45 - 2:46HH: No.
-
2:46 - 2:48JD: The answer is 4 billion dollars.
-
2:48 - 2:49Now what do you think of that?
-
2:49 - 2:51HH: Upside down.
-
2:51 - 2:55But this all comes together,
in my opinion, in the realm of policy. -
2:55 - 2:57We need dramatic accelerants,
is what you're saying. -
2:57 - 3:00Accelerants in R and D,
but also accelerants in deployment. -
3:00 - 3:04Deployment is innovation,
because deployment drives prices down. -
3:04 - 3:06The right policy can turn things around,
-
3:06 - 3:09and we've seen it happen already
in the electricity sector. -
3:09 - 3:14So, electricity regulators have asked
for ever cleaner sources of electricity: -
3:14 - 3:17more renewables,
less coal, less natural gas. -
3:17 - 3:18And it's working.
-
3:18 - 3:20It's working pretty brilliantly, actually.
-
3:20 - 3:21But it's not enough.
-
3:21 - 3:24So the German government
recognized the possibility -
3:24 - 3:26of driving down the price of clean energy.
-
3:26 - 3:28And so they put in orders on the books.
-
3:28 - 3:31They agreed to pay an extra price
for early phases of solar energy, -
3:31 - 3:32presuming the price would drop.
-
3:33 - 3:36They created the demand
signal using policy. -
3:36 - 3:39The Chinese created a supply signal,
also using policy. -
3:39 - 3:41They decided that solar
was a strategic part -
3:41 - 3:42of their future economy.
-
3:42 - 3:45So you had this unwritten agreement
between the two countries, -
3:45 - 3:47one buying a lot,
the other producing a lot, -
3:47 - 3:50that helped drive the price
down 80 percent. -
3:50 - 3:52We should be doing that
with 10 technologies, or a dozen, -
3:52 - 3:54around the world.
-
3:54 - 3:56We need policy as the magic sauce
-
3:56 - 4:00to go through those four sectors
in the biggest countries, -
4:00 - 4:01in all countries.
-
4:01 - 4:03And one of the things that animates me
-
4:03 - 4:07is that this requires people
who are concerned about climate change, -
4:07 - 4:08which should be everybody,
-
4:08 - 4:12those folks have to apply their energies
on the policies that matter -
4:12 - 4:14with the decision-makers who matter.
-
4:14 - 4:16If you don't know
who the decision-maker is -
4:16 - 4:18to decarbonize the grid,
-
4:18 - 4:21or to produce electric
vehicles in the policy world, -
4:21 - 4:22you're really not in the game.
-
4:23 - 4:26JD: I want to tell you
another story that involves policy, -
4:26 - 4:28but importantly, plans.
-
4:28 - 4:31Now, Shenzhen is a city
of 15 million people, -
4:31 - 4:33an innovative city, in China.
-
4:33 - 4:37And they decided that they were
going to move to electric buses. -
4:37 - 4:39And so they required
all buses be electric. -
4:39 - 4:43In fact, they required parking spots
have chargers associated with them. -
4:43 - 4:47So today, Shenzhen
has 18,000 electric buses. -
4:47 - 4:50It has 21,000 electric taxis.
-
4:50 - 4:53And this goodness didn't just happen.
-
4:53 - 4:57It was the result of a thoughtful,
written, five-year plan -
4:57 - 5:00that isn't just
a kind of campaign promise. -
5:00 - 5:04Executing against these plans
is how mayors get promoted, or fired. -
5:04 - 5:06So it's really deadly serious.
-
5:06 - 5:09It has to do with carbon,
and it has to do with health, with jobs, -
5:09 - 5:11and with overall economic strength.
-
5:11 - 5:17The bottom line is that China
today has 420,000 electric buses. -
5:17 - 5:20America has less than 1,000.
-
5:20 - 5:24So I think the question is:
Does the world have a five-year plan? -
5:24 - 5:26Or a 10-year plan?
-
5:26 - 5:30And I would say to you we have goals,
but we don't really have a plan. -
5:30 - 5:34What we need are a couple dozen
precision policy campaigns -
5:34 - 5:37and amazing entrepreneurs
with awesome teams -
5:37 - 5:39that are well-funded and focused,
-
5:39 - 5:41with measurable objectives and key results
-
5:41 - 5:46to solve this problem
in the 20 largest emitting countries. -
5:46 - 5:47We might be able to get there.
-
5:47 - 5:48What's your view?
-
5:48 - 5:50Do you think we're going to make it?
-
5:50 - 5:53HH: I'm an optimist, John.
I've seen this possible. -
5:53 - 5:55I've seen when nations
decide to do great things, -
5:55 - 5:57they can do great things.
-
5:57 - 6:01Think of America's rural electrification
or the interstate highway system we built. -
6:01 - 6:03Those are huge projects
that transformed the country. -
6:03 - 6:09What we did prepping for World War II:
we built 300,000 airplanes in four years. -
6:09 - 6:11So if we decide to do something,
-
6:11 - 6:15or when the Germans or the Chinese
or the Indians decide to do something, -
6:15 - 6:16other countries,
-
6:16 - 6:17they can get it done.
-
6:17 - 6:20But if this is sort of
piffling around the edges, -
6:20 - 6:22we won't get there.
-
6:22 - 6:24What do you think? Are you optimistic?
-
6:24 - 6:28JD: My take on this is,
I may not be optimistic, but I'm hopeful. -
6:28 - 6:33I really think the crucial question is:
Can we do what we must, -
6:33 - 6:35at speed and at scale?
-
6:36 - 6:41The good news is, it's now clearly cheaper
to save the planet than to ruin it. -
6:41 - 6:45The bad news is,
we are fast running out of time.
