There is a good article on Money & Energy on the Energy Bulletin website:

Excerpt:

"Money is nothing more than the right to command energy to do what you want it to do."

The WSJ had an interesting article yesterday about what is basically a global savings glut. Reading the article, it occurred to me that capital and energy are going in opposite directions--capital going up and energy resources depleting.  Of course, energy resources have been depleting since we first started mining for coal and drilling for oil.  The key point, as we know, is that we are looking at the peaking of our ability to grow the daily oil supply.

If we looked at the ratio of total world capital in dollars equivalent divided by total remaining BTU's, that ratio is increasing at an extraordinary rate--because the numerator (dollars) is rising while the denominator (BTU's) is falling.  

Another way to look at it would be total capital divided by total world BTU consumption (from nuclear + fossil fuel sources) per day.  In terms of oil equivalent, the world consumes the equivalent of about 200 mbpd from nuclear + fossil fuel sources--the equivalent of a billion barrels of oil every five days.  

We are now looking at the probability that the actual daily supply of nuclear + fossil fuel sources is about to enter a long term decline.   So, what this means is that even on a daily supply basis, the ratio of dollars to BTU supply will start skyrocketing because the numerator is rising while the denominator is falling, at least until the world economy starts contracting.  

The article on Money & Energy is very interesting indeed, especially if you follow the link to the Forbes article by Huber behind it. It reminds me of a comment made by the TVA management at the srart of the disasterous TVA plan to build 20 nuclear plants in the 70-80s, when they bragged that 'electricity would be so cheap that it would cost more to meter it than to make it'. TVA is still trying to pay off the debt from that misadventure.
TVA ran into the buzz saw of much cheaper oil, which fell like a rock in 1981. The nation's existing nuclear plants are making a lot of money for their owners today, as fossil fuels, not least coal, rise sharply. And, little credit is given to the nukes for avoiding CO2 emissions, the value of which is incalculable.
If fossil fuel generating plants were taxed for the true cost of CO2 emissions, or for the future value of the hydrocarbons they burn, we would already be in a crash program to replace them with nukes.
