These are examples of "green" cities that have or are building sustainable energy plans. For science, note that most of them are arctic or sub-arctic cities. They offer diverse combinations of approaches to clean sustainability, using resources at hand.
Ref.: ISTE student standards 1, 4, and 5. It is great that the new standards recognize the live-or-die mission of today's students. E.g.: Within their global digital networking environment------- they must enact citizenship that will make a planetary environment that is friendly to human survival (and the survival of many other species, too). This web site shows cities all over the northern hemisphere. Students can actually blog, facebook, or wiki or whatever with other kids in those same cities. Think of the science, economic, and social studies possibilities! Plus you could use Google Earth, a photo sharing site, and whatever (Picassa?) program that San Antonio lesson used to make a virtual tour of these star green cities. And of course you would apply all of that to mega projects here in Anchorage. A student network of kids in all those cities could grow into a network of future engineers, designers, and policy makers whose influence could go viral.
Voila--civilization saved!
