That's why I use Safari as well. The difference in power usage is enormous between Safari and Firefox.

I have Windows on Bootcamp but I don't know if Microsoft breaks down power usage like Apple does. I could compare Firefox to Edge, otherwise.

It's almost purely a function of CPU usage especially if you have an SSD.

I don't think the mac power usage thing takes into account GPU usage but for that you'd probably want to download something third party to check the watt usage itself.

In the early days of SSDs, power draw of an SSD was usually around the same as for a spinning platter. Has this changed?

According to OCZ's marketing material (http://ocz.com/consumer/ssd-guide/ssd-vs-hdd), SSDs use 2-4 watts vs 7 watts for HDDs.

Sorry. I did not see your comment first. Open the (new) Settings app, then click on Network & Internet and then usage details.
