AI has emerged as a powerful engine of economic growth but a Greenpeace report warns the boom is also driving a major rise in electricity use from data centers and chip manufacturing. Chris Gorin speaks with Lena Chang of Greenpeace East Asia and Judith Barish of CHIPS Communities United about why the report scrutinizes firms like Nvidia, Google and Apple, and how customer pressure can push suppliers such as chipmakers to adopt more renewable energy.

A full version of the interview will be released in coming weeks as part of our long-form interview series Zoom In, Zoom Out.

00:00So in your view, what is the main climate problem created by the AI boom at this moment?
00:06Semiconductors and data centers use vast quantities of energy. If we don't start creating
00:12more renewables in Taiwan, in the US, in the rest of the world, we're heading towards a climate
00:17catastrophe. So actually according to our report, the projection towards 2030, the global data
00:25center, electricity demand will triple, and especially the AI, you know, the hyperscale data center.
00:32And it's not only data center, but also from the chip manufacturing. And of course,
00:37if more power means more fossil fuel like emissions, because yeah, they are still burning the coal and gas.
00:46You've mostly focused on fabless chip makers like NVIDIA and AMD, rather than the fabs themselves,
00:52the manufacturers like TSMC, like Samsung in South Korea. So why the decision to place the pressure on
00:59the customers of TSMC, like NVIDIA and AMD, rather than on the producers themselves? You know,
01:04might you be letting the Samsungs and TSMCs of the world off the hook for their own emissions?
01:09We want to show it's possible for customers to require their suppliers to do more because
01:16it has been done. It's feasible. Taking example from Apple or Google, who are doing relatively
01:24better in our report, they actually set specific target for their supplier. For example, Apple said
01:33by 2030, all suppliers should use 100% renewable for their manufacturing process. And Google said,
01:42you know, both in the U.S. and Taiwan, AI at this point is propping up the economy. It's
01:48not going to be able to do that. So we actually think that it would be great for companies like
01:51NVIDIA, companies like Apple and Google to put pressure on the chip manufacturers. A company like
01:56TSMC is not selling to any of us. So they're not responsive to public demand for renewable energy.
02:03So they need to be hearing about it from Apple, from NVIDIA, from Google.
02:07You know, both in the U.S. and Taiwan, AI at this point is propping up the economy. It's the main
02:12driver. Now, if it comes to pass that both these climate goals and, you know, the economic development
02:19cannot coexist, which of these two goals should take precedence? And, you know, what are the things
02:25that we should be cutting in order to make one of these two things possible?
02:29In the case of all of the companies we're talking about, these are some of the largest,
02:37richest, and most innovative institutions that have ever been known in world history.
02:44I believe we can do both. I believe that we can invest in renewables and find less energy-intensive
02:51ways to power AI and also continue the economic growth that AI is bringing.
02:58And also I want to respond to the GDP growth because I think most of people in Taiwan don't feel that
03:04growth, actually, because it's highly concentrated in the semiconductor sector.
03:10So we really want to see a more like distributed profit coming from this economic growth.
03:18We want to see this economic growth, but at what cost? At the cost of climate crisis,
03:26at the cost of extreme weather events. So we believe those companies are capable of
03:33of designing the system with solutions in it.
