AMEE and Google PowerMeter let users calculate their carbon footprints

AMEE and Google PowerMeter are two ways the "here's your data, do something with it" methodology can be used to make people aware of their carbon footprints. Both use sensors such as smart meters to track and display energy consumption over time. (Disclaimer: OATV is an investor in AMEE.)

In a previous partnership between the two companies, Google used AMEE's profiling engine to let users calculate their carbon footprints. After completing the web form, users were taken to a Google Map mashed up with the carbon footprints of those nearby. Soon, we'll be able to do this without the web form. Like O'Reilly said, we are slowly transitioning out of a world where people typing on keyboards are driving collective intelligence
