I'm not talking about today's world...you are. I'm talking about tomorrow's world. No one has the silver bullet in their pocket right now, obviously, otherwise it would be at the fore of the debate. The point is, whatever the solution ends up being, it's going to take effort, optimism, foresight, research, development and a huge investment to get there...none of which you seem to support. Throwing up your hands and suggesting we'll never get off the oil industry's teet because we haven't already is self-defeating and irresponsible.
