We hear a lot these days about the steady rise in oil production here in the United States. Talk of "energy independence" tends to follow close behind.

It's a wonderful story. It would be an even better one if the facts and realities of oil production didn't intrude. We're not running out of oil, to be sure. But we have some energy-supply challenges ahead of us.

Understanding the reasons why is an important step in preparing for a future not quite as energy abundant as some lead us to believe.
