I spoke last night at Vanderbilt's Owen School of Business to Nashville's Net Impact chapter, and a broader community of green innovators and pioneers in Nashville -- architects, entrepreneurs, energy-efficiency gurus, wellness and yoga practitioners, foodies, activists.

I spoke for about half hour about the bottom-line argument for the clean-energy revolution, energy development and green jobs nationally and locally, and then tapped some locals to pop up and talk briefly about the work they're doing:

• Jeff Barrie, Kilowatt Ours
• John Stovall, Repower America
• Jacob Gordon, Treehugger
• Liz Workman, Belmont Lotus
• Sarah Scarborough, Partners Tea
• Miranda Whitcomb, Frothy Monkey
• Josh Womack, Verdegoh
• John Abernathy, DAAD Group Architecture

The bigger goal was to give a snapshot of how much environmental progress is quietly, gradually building in Nashville (not widely regarded as the epicenter of the green movement). Big thanks to each of my guests and to a terrific audience. I was proud to be a part of this community.
