Support for Forum comes from Broadway SF, presenting Parade, the musical revival based on a true story.

From three-time Tony-winning composer Jason Robert Brown comes the story of Leo and Lucille Frank,

a newlywed Jewish couple struggling to make a life in Georgia. When Leo is accused of an

unspeakable crime, it propels them into an unimaginable test of faith, humanity, justice, and devotion.

The riveting and gloriously hopeful parade plays the Orphium Theater for three weeks only, May 20th through June 8th.

From KQED in San Francisco, I'm Leslie McClurg. I'm in today from Mina Kim.

Coming up on forum, the internet produces about a billion tons of greenhouse gas emissions per year.

That's roughly the same as the aviation industry,

according to one recent study. Every time you click a photo or you like a post or you get an email,

that's backed up in the cloud and then it's stored in a data center, a massive facility filled with

thousands of computer servers. And those use a ton of electricity. We will talk about our digital carbon footprint

and whether we can make a difference. That's next after this news.

This is Forum. I'm Leslie McClurg. I'm in today for Mina Kim. And as handy as AI is, it's really not that great for the planet. So every time I ask ChatGBT, GBT, a question, the response that it generates requires 10 times more energy than asking Google that same question. And that's a huge reason why the electricity

demand at data centers around the world is forecasted to double between 2022 and 26. I found those

stats in reporting cited by Andrew Chow, who reports for Time magazine, and he joins us now to explore

our digital carbon footprint, basically.

Every click we make and every file we back up.

It's great to be here. Thanks so much.

So kind of take us inside a data center. What does that look like?
