How the Google Math Adds Up:
1. Google is rapidly becoming the nation's largest single consumer of electrical energy.
2. 2007: Google announces their goal of producing renewable (solar) electricity as cheap as coal. The goal: $ 0.025/kwh
3. Plentiful solar electricity is generated during the common peak demand periods, hot summer afternoons.
4. 2009: Google announces the PowerMeter to help implement the "smart grid" as they envision it. A properly implemented smart grid could increase the selling price of peak demand power to $ 0.25/kwh or more.
Therefore, #4 causes a 3x to 10x increase in the profits of #2, while #3 + #2 solves problem #1.
