You may have had the experience of unboxing furniture
0
8505
3754
00:12
and come across instructions that go something like this:
1
12259
3420
00:15
"Assemble the bookshelf according to the provided diagram."
2
15679
3378
00:19
Yes, I know what a bookshelf looks like.
3
19724
3045
00:22
Probably wouldn't be reading the assembly instructions
4
22769
2544
00:25
if I didn't need a little more help with the process.
5
25355
3086
00:28
Or maybe you've opened a cookbook
6
28441
1794
00:30
with an author who thinks you're already somewhat of a chef.
7
30235
3170
00:33
"Deglaze the pan."
8
33446
1460
00:35
What?
9
35448
1252
00:36
(Laughter)
10
36700
1001
00:37
OK, off I go on a separate search to understand whatever that means.
11
37742
4171
00:42
Instructions that tell you what to do and not how to do it
12
42414
4921
00:47
are pretty useless.
13
47335
1544
00:49
And yet, even when we're talking
14
49212
1627
00:50
about something as important as climate change,
15
50881
3003
00:53
we hear them all the time.
16
53884
1710
00:55
“Transition to renewable energy.”
17
55927
1710
00:57
“Electrify everything else.”
18
57679
1460
00:59
“Deploy solutions that are equitable and fair.”
19
59180
2878
01:03
Yes, let's do all of that.
20
63310
4004
01:07
But how?
21
67314
2252
01:10
Answering how is where we understand which solutions are actually feasible,
22
70775
6257
01:17
whether that be with today's infrastructure,
23
77032
2627
01:19
our evolving regulatory environment
24
79659
2044
01:21
or any of the other number of dependencies and constraints
25
81703
3086
01:24
that we have to consider.
26
84831
1752
01:27
How we solve climate change
27
87626
1293
01:28
also depends on our very definition of the problem.
28
88960
3253
01:32
It's a scientific challenge, a sociopolitical issue,
29
92213
3713
01:35
an economic problem and so much more.
30
95967
2670
01:38
And how we solve it will depend on how we frame it.
31
98678
3629
01:43
There is no single answer.
32
103391
2002
01:46
I'm a scientist,
33
106728
1293
01:48
so I approach climate change as a scientific challenge.
34
108021
3837
01:52
I'm also a techno-optimist
35
112442
2127
01:54
and artificial-intelligence product manager,
36
114569
2753
01:57
so I also approach it as a technological one.
37
117364
2877
02:01
When it comes to a sustainable future,
38
121952
2127
02:04
artificial intelligence can help us do three critical things.
39
124079
3837
02:08
First, it can help us understand climate change
40
128333
3545
02:11
and its effects on Earth's ecosystems.
41
131878
2878
02:15
Second, it can help us optimize current systems and infrastructure,
42
135173
4379
02:19
because we can't just start over from scratch today.
43
139594
3962
02:24
And third, it can help us accelerate the breakthrough science we need,
44
144182
5047
02:29
such as fusion as a carbon-free energy source.
45
149270
2962
02:32
Today, I'd like to talk about that second one,
46
152899
2377
02:35
optimizing current systems,
47
155276
1752
02:37
and specifically, how we can use AI to harness a superpower
48
157070
4004
02:41
we already have in this fight:
49
161074
2085
02:43
wind energy.
50
163868
1127
02:46
Renewables are unquestionably a key to a sustainable future,
51
166913
3670
02:50
but the problem is they're unpredictable.
52
170583
3337
02:53
Sometimes, the sun shines and the wind blows,
53
173920
2461
02:56
and sometimes, it just doesn't.
54
176423
2544
02:59
Now, for an electricity systems operator,
55
179509
3045
03:02
who needs supply to meet demand in real time, 24-7,
56
182595
5089
03:07
this is hugely problematic.
57
187726
2252
03:10
Renewables can't be 100 percent reliably scheduled.
58
190562
3587
03:15
Now, unfortunately, fossil-fuel plants are the opposite.
59
195066
3545
03:19
You can burn a specific amount of coal at a set time
60
199195
3754
03:22
to deliver exactly the amount of electricity you want
61
202949
2836
03:25
in a predictable time window.
62
205827
1919
03:28
So ...
63
208788
1335
03:30
if you're a power systems manager
64
210165
1710
03:31
whose job is to literally keep the lights on,
65
211916
3129
03:35
which source are you more confident depending on?
66
215045
2627
03:38
But here's one of the places where AI can come in.
67
218965
2961
03:41
It is a powerful tool for forecasting.
68
221926
2837
03:45
AI systems can ingest vast amounts of historical data
69
225805
3045
03:48
and help us predict future events.
70
228892
2252
03:51
So, while we can't eliminate the variability of wind,
71
231853
4087
03:55
we can use AI to more accurately predict its availability.
72
235982
4463
04:01
That was my team’s “what” to do.
73
241196
2168
04:03
Use AI to accelerate the transition to renewables, like wind energy.
74
243907
4296
04:08
The tough part was the “how” to do it.
75
248995
3629
04:13
First, we researched the challenge.
76
253833
2419
04:16
We read papers, we spoke to domain experts,
77
256294
2586
04:18
we found out everything we could about the problem.
78
258880
3212
04:22
Our team, which is a mix of research scientists,
79
262425
2378
04:24
engineers, a product manager, a program manager
80
264803
2544
04:27
and an impact analyst,
81
267347
1585
04:28
decided that a neural net trained on historical weather data
82
268973
3963
04:32
and turbine power-production information
83
272936
2210
04:35
would likely help us accomplish our goal.
84
275188
2127
04:38
Next, we needed to find two core elements:
85
278233
4296
04:43
data to train the system
86
283154
2211
04:45
and a partner who was willing to deploy it.
87
285365
2836
04:49
Both of these can be major obstacles
88
289077
2669
04:51
when it comes to deploying AI in real-world scenarios.
89
291746
3670
04:56
Let's start with data.
90
296584
1669
04:58
There are massive gaps in climate-critical data --
91
298795
3712
05:02
not just in electricity,
92
302549
2043
05:04
but in agriculture, transportation, industry and many other sectors.
93
304592
5339
05:10
Some of our data, we could purchase or download for free --
94
310682
3462
05:14
weather forecasts, for instance.
95
314144
2252
05:16
But some of the data we needed was proprietary,
96
316437
4130
05:20
and this would be, like, turbine power-production information
97
320608
4171
05:24
and other operational data from the wind farms.
98
324821
2586
05:27
Now, we needed that proprietary data so that we could train our models
99
327407
4963
05:32
to learn the relationship between historical weather
100
332370
3545
05:35
and historical power production,
101
335915
2086
05:38
so it could then then make predictions about future power availability
102
338042
4130
05:42
based on what data said about future weather.
103
342172
2919
05:45
Now it's probably worth mentioning here
104
345800
1919
05:47
that we were looking at a few years of data
105
347760
2086
05:49
on hourly resolution,
106
349888
1167
05:51
not historical data at a timescale
107
351097
1794
05:52
that would have massive climactic differences from present day.
108
352932
3170
05:56
In addition to data,
109
356144
2169
05:58
we needed to find a partner with domain expertise
110
358313
3962
06:02
and the willingness and scale to test new systems.
111
362275
3503
06:06
You know, surprisingly, this can be a major hurdle
112
366279
4171
06:10
when it comes to deploying AI in the real world.
113
370491
2920
06:13
Believe it or not, it's not every wind-farm manager
114
373453
3044
06:16
that wants to let a bunch of AI researchers
115
376539
2002
06:18
test on their multimillion- or multibillion-dollar systems.
116
378583
4504
06:23
But the thing is, in order to prove that AI works,
117
383129
3879
06:27
we have to have deployment opportunities in the real world.
118
387050
3712
06:31
Luckily for us, Google was a ready and willing partner.
119
391721
3462
06:35
OK, yes, DeepMind is a part of Google,
120
395225
3253
06:38
but it's not a given that they would let us test on their systems.
121
398519
5047
06:44
Yet they let us test on 700 megawatts of their wind-power capacity,
122
404108
3671
06:47
which is equivalent to a large wind farm in the United States.
123
407779
3503
06:51
This made them an excellent proxy for external wind-farm operators.
124
411282
4505
06:56
They also lent us an expert team to advise on metrics and benchmarks
125
416246
4754
07:01
and to share the data that we needed.
126
421000
2628
07:03
This is another critical component of AI for the real-world deployments.
127
423628
4212
07:08
Working with a domain-expert team that can tell you what they need,
128
428258
4879
07:13
how they need it to work,
129
433137
1418
07:14
which constraints keep the system safe,
130
434555
2545
07:17
what quantifiable metrics to use to measure AI performance
131
437141
4588
07:21
and how much better that AI performance needs to be
132
441771
3629
07:25
than their previous systems
133
445400
1334
07:26
to make the cost of switching over even worth it.
134
446776
2961
07:29
And that's just to name a few.
135
449737
1752
07:32
So at this point, we have our idea,
136
452448
2837
07:35
we have our data, we have our deployment partner.
137
455326
3045
07:38
Now, to test and deploy our system.
138
458371
3503
07:43
Improving the accuracy of electricity-supply forecast
139
463501
2795
07:46
is incredibly important.
140
466337
1752
07:48
If predictions are higher than actual generation,
141
468631
3128
07:51
renewable electricity managers may not have enough supply to meet demand.
142
471801
4463
07:56
This, in turn, drives the purchase of carbon-intensive fossil fuels
143
476264
3628
07:59
to cover that gap,
144
479934
1335
08:01
because they're largely what makes up backup generation.
145
481269
2627
08:04
Now, the good news.
146
484605
2002
08:07
Our AI system performed 20 percent better than Google's existing systems.
147
487400
6298
08:13
Even better news is that Google decided to scale this technology.
148
493698
3795
08:17
And scaling is so important.
149
497535
3295
08:21
We will run out of time in the climate countdown
150
501581
2711
08:24
if we aren't deploying solutions that are widely applicable.
151
504292
3795
08:28
This particular solution is being developed
152
508880
2002
08:30
into a software product
153
510882
1251
08:32
that French company Engie is among the first to pilot.
154
512133
2753
08:36
But, you know,
155
516179
2127
08:38
it doesn't even take a major research organization to do this kind of work.
156
518348
4004
08:42
Where we focused on AI for supply-side forecasting,
157
522393
3420
08:45
a small UK-based nonprofit called Open Climate Fix
158
525855
4004
08:49
is focusing on AI for demand-side forecasting.
159
529859
3045
08:53
They found a willing partner in the UK National Grid,
160
533529
3045
08:56
and are currently deploying forecasts that are two times more accurate
161
536616
5005
09:01
than the UK grid's previously used systems.
162
541621
2836
09:05
Now, all of this is to say is that AI can help us
163
545375
4504
09:09
with the transition to renewable energy,
164
549921
1960
09:11
but scientists and technologists,
165
551923
2043
09:13
we're not going to be able to do that alone.
166
553966
2294
09:16
We need to be working with partners and experts
167
556302
3087
09:19
who can teach us the “how.”
168
559430
1669
09:21
So for those of you interested in this space,
169
561974
4046
09:26
if you're a domain expert,
170
566020
2211
09:28
please share the problems you face and the challenges that you have
171
568272
3546
09:31
so that our sector can ensure
172
571818
1960
09:33
that AI pursuits will have impact in the real world
173
573820
3253
09:37
and not be purely academic.
174
577115
2210
09:40
Even better,
175
580118
1376
09:41
if you want to incentivize ML researchers to work on your problems,
176
581536
3253
09:44
I'll let you in on a little secret:
177
584831
2335
09:47
build a competition, and they will come.
178
587208
2586
09:49
(Laughter)
179
589836
1293
09:51
It's true.
180
591170
1168
09:52
Just don't forget the datasets and metrics.
181
592338
2669
09:55
If you are a data holder, where it’s safe and responsible to do so,
182
595675
7007
10:02
please share data related to those challenges.
183
602682
3211
10:06
If you're not sure whether the data you have is even climate-critical,
184
606436
3420
10:09
you can check out Climate Change AI's website,
185
609856
2460
10:12
where they have published a wish list of climate-critical datasets.
186
612358
4463
10:16
Access to these datasets
187
616821
1251
10:18
would unblock crucial research and innovation in AI for climate.
188
618114
4046
10:23
If you're a deployment partner,
189
623619
2378
10:25
please, let us know who you are,
190
625997
2002
10:28
especially if you're willing to test innovative systems.
191
628040
3254
10:32
And for everyone who's interested in this space,
192
632753
3504
10:36
please know you do not have to be technical to work in tech.
193
636299
4337
10:41
AI for climate action requires a variety of skill sets
194
641429
4046
10:45
and a diversity of backgrounds
195
645475
1793
10:47
that, yes, includes research scientists and engineers,
196
647310
3295
10:50
but it also includes ethicists and policy experts,
197
650646
3629
10:54
communication teams, product managers,
198
654275
2336

It will not solve all problems driving climate change.

It isn't even the right tool for many of the challenges that we face.

AI is also not a technology without tensions.
