Gates buys offsets to cancel out his own personal emissions, to the tune of about $9 million a year, he said at the roundtable, but doesn’t expect many of those offsets to make a significant dent in climate progress on a broader scale: “That stuff, most of those technologies, are a complete dead end. They don’t get you cheap enough to be meaningful.
“Carbon sequestration at $400, $200, $100, can never be a meaningful part of this game. If you have a technology that starts at $400 and can get to $4, then hallelujah, let’s go. I haven’t seen that one. There are some now that look like they can get to $40 or $50, and that can play somewhat of a role.”
Will AI be good news for innovation?
During the discussion, I started a tally in the corner of my notebook, adding a tick every time Gates mentioned AI. Over the course of about an hour, I got to six tally marks, and I definitely missed making a few.
Gates acknowledged that AI is going to add electricity demand, a challenge for a US grid that hasn’t seen net demand go up for decades. But so too will electric cars and heat pumps.
I was surprised at just how positively he spoke about AI’s potential, though:
“AI will accelerate every innovation pipeline you can name: cancer, Alzheimer’s, catalysts in material science, you name it. And we’re all trying to figure out what that means. That is the biggest change agent in the world today, moving at a pace that is very, very rapid … every breakthrough energy company will be able to move faster because of using those tools, some very dramatically.”
I’ll add that, as I’ve noted here before, I’m skeptical of big claims about AI’s potential to be a silver bullet across industries, including climate tech. (If you missed it, check out this story about AI and the grid from earlier this year.)
