I think it is healthy to be skeptical, but I hope your skepticism is founded on something other than the fact that I have an opinion you don't like. That isn't skepticism, it's just head-in-the-sand syndrome.
I try to stick to presenting what I know, which is the facts and the economic theory behind things. If I'm sharing my opinion, I always try to preface it as such. My opinions are based on the fact, but in the end they are just my opinions. If you are skeptical of the source of the facts, then that is another issue. I am highly confident in their accuracy, however.
Now, just because I have a lot of working knowledge of the industry because of my involvment in it, doesn't mean I can't be of the opinion that we should move away from an oil based economy. That doesn't mean we should all live in straw huts and ride horse drawn buggies tomorrow. Obviously it is going to be a gradual transition from an oil-based economy, but it is a transition that will happen. How painful that transition is for us will depend on our willingness and desire to be part of the transition.
If we decide we'll just ride it out and not be part of the transition, then we will one day be hit with prices that make the current ones seem like peanuts, and we will have no means to combat it other than to face a major economic depression and take our lumps that way.
Or, we can begin the transition on our terms so that when the inevitable crunch comes, we will be prepared to weather the storm.
I've always said (on these forums, to my professional colleagues and clients, to my students, etc.) that this planet will never run out of oil. I say that not because it is plentiful, but because the laws of economics will dictate it. As demand outstrips supply, prices will only continue to rise. As this happens, our demand for oil will eventually be destroyed (replaced by alternatives), and a bunch of oil we neither want or need will be left sitting in the ground. "Exploiting what we have and then moving on" is not a realistic option, because that isn't the way things work. Changes like this require proactive thinking.
In the end, it all comes down to objectives, like I stated in the other thread. Personally I believe (my opinion) that making oil cheap is the wrong objective. Again, one of my favorite analogies is "you don't cure an addict by providing him with a bunch of cheap crack."
I guess the question should be: what is your objective?
