* The World is conveniently broken up into 6 groups of countries according to location and economic strength (Figure 11). The Organization for Economic Co-operation and Development (OECD) is the Major "player" in this grouping.
* The present World reserves of U will provide far less than 1 trillion boe if used in the Light Water Reactor configuration of today's nuclear fission power plants (Figure 22). If the same amount of U were to be used in LMFBR's, the total energy reserve would be ~ 14 trillion boe.
* When comparing the cumulative energy needs against the economically recoverable fossil fuels, it is evident that society will have to switch from a world powered by fossil fuels to perhaps a nuclear powered world in the middle of the 21st century (Figure 23).
* The use of solar energy has the same potential to provide inexhaustible long-term energy if energy storage problems, high capital costs, and geographic heterogeneity problems can be solved (Figure 24).
Environmental & Societal Factors
* Sometime in the mid-21st century, the world will need a new, safe, clean, and economical source of energy to satisfy the needs of both developing and developed nations.
* The real question is now how much energy is needed, when, and where it will come from?
* The connection to Space Resources is that the Moon contains enormous amounts of 3He, a valuable and clean fuel for fusion reactors. More later!

Typical Questions That Stem From This Lecture:
1.) What is the expected CO2 emission rate (billion metric tonnes/y) from the burning of fossil fuels in the year 2025 if the current world mixture of fuels stays the same?
2.) How much does the annual net percentage increase in the World population (as assumed in the U. S. Census Bureau predictions) change from 1994-5 to 2049-50? Hint: you may have to use the Web.
3.) What effect would a doubling of the per capita energy use rate in non-OECD Asia have on the total World energy use rate (in Billions of boe) in 1992? How much effect would a 50% reduction in the U. S. per capita use have on the World energy use rate in 1992?
