A picture is worth a thousand words. This graph compares the price history of solar energy to conventional energy sources. The comparison is striking. This is what a disruptive technology looks like. While conventional energy prices remained pretty flat in inflation adjusted terms, the cost of solar is dropping,fast, and is likely to continue doing so as technology and manufacturing processes improve.

Nearly everyone is failing to take into account the role of geology, oil and energy limits in their predictions – and we’re racing towards disaster.

The next decades will witness a global battle between geologic depletion and technological advancement, as modern society demands ever-increasing quantities of energy from an aging fossil fuel supply and a nascent renewable energy sector.

"Oil prices on the New York Exchange dropped sharply through mid-day Thursday to the lowest level of the year--$85.71 per barrel—before recovering modestly to close Friday at $88.01.
