The huge distortions imposed on the modern industrial nations by the flood of cheap abundant energy that washed over them in the 20th century can be measured readily enough by a simple statistic.

The total direct cost for all this energy came to around $500 billion a year in 2005, the last year for which I was able to find statistics, or about $1667 per person per year.
