This is Part 2 of a post by GliderGuider. Paul's website can be found here.

In Part 1 I derived a scenario for the changing global energy supply picture between now and 2050. The conclusion in that article was that due to the rapid decline of oil and natural gas supplies, the total energy available to the world would drop by about 30% in that time. That single figure, however, doesn't tell us much. The picture is dramatically complicated by the fact that the world will be forced to transition from an energy economy largely based on fuels (oil and natural gas) to one based primarily on electricity generated from a variety of sources. In addition, most of the world's population growth in that time will occur in the energy-poor and economically-poor developing world.

In order to gain more insight into how changes in energy will affect different parts of the world, this article will examine the impact of energy declines in specific countries. We will disaggregate the global picture presented in the baseline energy article, and apply those changes to the specific energy circumstances of individual nations. Those energy changes will be translated into their effect on national GDP. The national population changes projected by the UN Medium Fertility Case will be used to translate the national GDP changes into average per capita GDP changes for each country.

The examination of changing per capita GDP, driven by changes in the energy supply and national populations, will help us understand the distribution and extent of wealth and poverty over the next half century.
