How did you come to this?

Great question. Based on my use, it would be a lot more than 5 watts/day.

Yes, the trace comparison in the link (which the author says is for browsing YouTube in Firefox) shows average CPU usage is down from roughly 5% to roughly 4%. That’s a great improvement, but I’d like to know why we should assume that translates to 5 Watts.
