I've seen alternative & sustainable energy technology evolve tremendously in my lifetime, and yet I know there are applications, like hydroelectric energy, that continue to be valuable contributors to our world. One that, sadly, has diminished mightily in most of our eyes, is the water-pumping windmills. At one time they were spread widely across our country, but now they are mostly broken, non-functional, and rusty relics seen here-and-there.

Timmon B. Wallis takes his life-long efforts for peace and the future of the planet to new depths and heights with his book, Warheads to Windmills - Preventing Climate Catastrophe and Nuclear War.

We ask 3 sustainable energy professionals about their visions of our future, both technologically and personally, living responsibly on the Earth. We speak with Jeff Knutsen of A-A Exteriors, Jim Olson of E3 Coalition, and Zeus Stark of Next Step Energy. Who and how will we be as we grow into a responsible energy future?
