Google's commitment to the environment

I knew Google was green or whatever, but hadn't looked into what that actually means until very recently. Here are some highlights:

1. RechargeIT: Google has been keeping track of how many MPG its fleet of hybrids and electric cars get and publishing the results. One goal is to demonstrate how plug-in hybrids work. Here's an excellent video on just that.
2. Solar Panels: the campus in Mountain View sports a 1.6 megawatt solar panel installation, apparently one of the largest corporate installations in the US (see here).

EDIT: This week, at the National Clean Energy Summit, Google announced its plans to finance research into EDS (Enhanced Geothermal Systems). It's touted as a reliable, consistent, global energy source (as compared to wind, which is intermittent and available in fewer places). Anyway, here's a Dot Earth post on the subject.
