1.4 billion project, to produce enough electricity for 140,000 homes, if i'm doing the math right, works out to about $10,000 per home. that seems like a reasonable payback. if google has a 12% share, that's around 17,000 homes. how many employees does google have? more than 20,000.
so, if they throw in a bit of conservation, google is buying solar power for its workforce's homes, at about $10,000 each. Seems like they break even on the investment while getting decent pr out of it. If it costs $1.4 billion to build, does that make it an easy target for terrorists (from, say, redmond) to hit with a dirty bomb?
