On this edition of ST, a discussion of business practices and sustainability goals in contemporary America -- and of where these two ideas do and don't (and might someday) overlap. Our guest is Bill Roth, a business-book author, green entrepreneur, and consultant on sustainability; he'll be speaking soon in our community. Roth is also the creator of the Earth 2017 website, which aims to "coach business owners and leaders in their development of strategies and projects that align with the mega-trends of [this planet] in 2017." Roth's past business experiences have included serving as Senior Vice President Energy Services for PG&E, COO of Texaco Ovonics Hydrogen Solutions, and President of Cleantech America. He also helped to launch of the first hydrogen-fueled Prius as well as the first web-based, meter-linked energy information system. He'll be speaking at the daylong "Bringing It Home: Focus of Sustainability" conference, which is happening tomorrow (Thursday the 11th) at the TCC Thomas K. McKeon Center for Creativity (at 909 S. Boston). The event will be co-sponsored by TCC Metro and Sustainable Tulsa, and it's free to the public.
