Quote about end of the oil age

Thomas Freidman was asked questions by readers of Time magazine. At the end he quoted someone else as his response to the future of energy. I do not know the original person who said this nor do I know what the exact question was but I liked what was said.

"The stone Age did not end because we ran out of stones."

There was more to the quote, but the point being, we may not run out of the oil age because we run out of fossil fuels. The oil age will end with innovation.

This holds true for all sorts of things as well. Things only will change with innovation and imagining something new. The mainline church will not end because we run out of people needing community. Rather the current expression of the mainline church will end because there is something new on the horizon.
