The week before Christmas, I was interviewed by Phil Windley of itconversations.org. The conversation started out about schedules for the internet of things, but was published under the title Open Source Smart Energy. I was coming off a cold, and sounded like a frog croaking, but I enjoyed it, especially because the interview also let me meet Udell, whose work I have long admired. The conversation covered many of the high points of smart energy, including enterprise interaction, demand response, microgrids, and transactive energy.
