Also today, Google took out a full-page ad in USA Today to promote ideas for combating global warming. The ad is the product of a collaboration between Google and Global SchoolNet. Google invited teachers and students to use Google Docs and Spreadsheets to brainstorm ideas. One of the ideas -- put light sensors in all office and school buildings so all lights go off when the rooms are empty -- is displayed on the full-page ad (PDF).
