Kai Ryssdal: The Internet, as most of us know, can be an amazingly valuable tool. It can also be a colossal waste of time. All told, we watched 700 billion YouTube videos this year.

Adriene Hill: 17 million people have watched a three-year-old cry over a YouTube pop star.
Toddler: 'Cause I love Justin Bieber.
Woman: You're crying because you love Justin Bieber?

Webb: It is growing and it's growing mainly because of the new applications, video.
But, Rich Brown from Lawrence Berkeley National Laboratory says it's important to keep it in perspective. The Internet is still a relatively small energy suck, compared to things like cars.
Rich Brown: That shouldn't be the primary focus of where we're trying to cut energy use. There's a lot bigger fish to fry.
Which means I don't have to feel too guilty about spending a few minutes watching the latest Taylor Swift video... except maybe that it's Taylor Swift.
I'm Adriene Hill for Marketplace.
