Imagine how hard it would be to stick to a budget in a store with no prices. Well, that's pretty much how we buy electricity today.from the Official Google Blog: Power to the people
Apparently Google is going to work towards making the information from power "Smart Meters" (Not installed in MY home yet) easily available. So you waste less money. So you pollute less. So you save the planet!
For example, lets say somehow I get sucked into watching "Paris Hilton's Best Friend Forever" reality TV show. Google could help me understand that not only did I completely botch 1/2 an hour of my precious life, but I spent $32.6 cents in energy that I could have used to buy organic carrots instead of plunging our planet further into a carbon death spiral.
Groovy. Now if only Google could tell me how much I'm spending on my cell phone bill before it shows up on my doorstep...
