Shillue:

There are 5 laptops plugged in right now in this SBUX I am in. Let’s say and average of two per store are running all the time. 85 Watts of power x 12 hrs. x 365 days. Divide that by 1000 for the KwHours and you have 372. x the national average of .12 per KwH and you get $44.67 per laptop cost per year. With my (conservative!) 2 users per SBUX, and 9000 locations (there are 11,000 but I took away two thousand for good measure because there are a lot of small locations with no room for seating.)

that’s $89.35 x 9000

$804,168 a year Starbucks eats in laptop power costs.

Wow, that’s a high cost for a free service.

But worth it!

By my calculations, these laptop users alone spend $165,564,000 a year at Starbucks.
