This is something Kansans can be really proud of. From the New York Times:

The first gatherings after the tornado produced a surprising civic consensus in a community where “green roofs” and the “heat island effect” were foreign concepts. As Dea Corns, a real estate agent who manages the Greensburg State Bank with her husband, Thomas V. Corns, recalls, “We decided to put the ‘green’ in Greensburg.”

These days, the technical language of the green building world is in everyday use as Greensburg sets out to achieve the distinction that the former Kansas governor, Kathleen Sebelius, now the secretary of Health and Human Services, described in a news conference two years ago. "We have an opportunity of having the greenest town in rural America,” she said.

Last year, leaders approved a redevelopment plan drawn up by the architectural firm BNIM, based in Kansas City, Mo., that called for Greensburg to be a “truly sustainable community that balances the economic, ecological and social impacts of development,” and “a laboratory for research on sustainable design and community development.”
