Human beings are not creatures of facts and logic - they are people who live in stories. This is not new - it has always been that way. We have certain collective narratives that almost everyone automatically accept without further thought. It is how we make sense of the world. These narratives keep us sane by allowing us to filter out the hurricane of information swirling around us daily and making some sense of it. The current narrative that most people subscribe to is that economic growth will eventually return or we have plenty of oil but the government is not letting is drill for it. For that reason I am not convinced that you will ever convince the average citizen (not a technical person) by showing them data. I am a data person and I have tried it with my family and their eyes glaze over.
So I think you can only change people's views is by constantly telling them a different story - one that is consistent with their current experience. It worked pretty well with my family. A story something like this:
If peak oil is a possibility - what would it be like? Well for starters the peak oil story is not about potential oil under the ground. That oil is irrelevant because it cannot be used. Peak oil is only about one thing - the ongoing flow rate of oil into the economy. For all of the last century and up until about 2005 that flow rate grew steadily. But that flow rate pretty much came to a halt in about 2005 and for the last half decade could not grow. And as you would expect the global oil price started to rise. That's what happens when supply cannot keep up with demand. Economists told us not to worry - Mr. Market would immediately react with increased supplies, reducing price - but it did not happen.
The global oil price (Brent Crude) is now consistently above $100 per barrel after staying below $20 for most of the last century. This is what peak oil is like. This is what peak oil was predicted to be like. High energy prices eat away at the economy by pouring sand into the gears of the economy. Every country in the world tried to compensate for this slowdown by increasing debt. The world is now ludicrously broke - with no chance of paying off this debt bubble. This is peak oil - it is not about resources under the ground - it is about oil production rate - and high oil prices. Don't tell me peak oil cannot happen - it is happening.
I have personally found that my family is stumped when I present this story in this way. They don't have an answer. But the story caused a few of them to ask to see some data. Then I showed them the data. Now they are worried and they hate me :-)
