Here's a quickie informational link. It's for a "virtual town" called Greenville that's been fabricated by the Technology CEO Council—the uber-tech-power lobbying group that includes big-name CEOs like Michael Dell, Mark Hurd of Hewlett-Packard, Sam Palmisano of IBM, and Paul Otellini of Intel. (When was the last time you saw Dell, IBM and HP get together on something!)
Anyway, this is a rather simplistic visual representation and statistics site that talks about how various technologies could help in the different buildings that make up the town, from hospitals and homes to small businesses and transportation hubs. So, for example, the airport in Greenville has a cell phone parking lot to cut down on idling time when flights are late and smart meters for electricity and smart sensors for watering are in the office used by an example small business.
Nothing really that's rocket science, but a highly visual way to "see" where various green technologies could have an impact on your daily life.
