Concern over global warming has brought attention to the impact of large scale use of fossil fuel across the world. Additional at some point in the future (it maybe 100 years it may be 200) the world will run out of fossil fuel or it will become so expensive that the cost of traditional energy production could destabilize the world's economy. While green (or renewable if you like) energy sources will forestall this day of reckoning - the sun doesn't always shine and the wind doesn't always blow.
Is there a point at which we come to recognize that without reliable and affordable energy meeting the needs of a growing world population and global economy maybe next to impossible?
Will we be forced to impose social policies such as worldwide population growth control to "live within our means" or expand the development and use of controversial power sources such as nuclear?
How would you deal with the paradoxes over the competing needs for affordable energy, finite and dwindling supplies of natural gas & oil as well as the need to address climate issues?
