I came across a great idea at Tree Hugger. There article “Selling Home Solar Like a Cell Phone Plan” article talks about how more and more new energy consumers are expected to come online in the developing world. If they use cheap and dirty power sources like coal, the effects on the global climate could be catastrophic.
Simpa Networks has a great idea. They are using the cellphone pricing model to make expensive solar energy a cheap option for new energy consumers. This could have a really positive effect on both solar energy technology and power production in the third world.
