Geologist David Hughes (05:16)
Silver Donald Cameron introduces Hughes and highlights his accomplishments. Hughes believes we are reaching the peak of our ability to supply energy sources; we have obtained approximately 40% of all recoverable hydrocarbons.
Cost and Worth of Oil (08:00)
Hughes states that slaves were the precursors to oil; he explains a barrel of oil's worth in terms of labor. He cites statistics on oil consumption and expenditures; we are likely at peak oil deliverability.
Net Energy (09:03)
Hughes admits we will never run out of hydrocarbons and explains a pyramid diagram. He discusses the energy return on investment in respect to various sources.
Energy Consumption (08:01)
Hughes discounts the concept of an alternative completely replacing 31 billion barrels of oil a year; conservation is necessary. Cheap energy is a key concept in North American growth. Hughes cites recommendations for change; politicians are followers, not leaders.
"Hitting the Wall" (07:27)
The loss of easily obtainable hydrocarbons will affect price which in turn affects demand. Hughes considers the effects of the growth paradigm and localization.
Caltech Study and Society (09:57)
David Rutledge suggests that 90% of easily obtainable hydrocarbons will be gone by 2068 and CO2 levels in the atmosphere will rise. Hughes considers rising temperatures and sea levels, managing carbons, societal collapse, and energy consumption.
Energy Depletion (02:51)
The Intergovernmental Panel on Climate Change has 40 scenarios for carbon emissions by 2100. Hughes cites the need for objective analysis.
Tipping Points? (04:37)
Rutledge's study is a statistical analysis of the past. Hughes considers permafrost melt and the importance of hydrocarbons.
Supply/Demand Balance (04:40)
The loss of hydrocarbons will create a food crisis. The present population of the Earth is unsustainable.
Personal Consumption (07:46)
Hughes cites lifetime consumption statistics. He and Cameron consider humanity's response to the hydrocarbon crisis and personal behaviors. Cameron summarizes Hughes' perspective on energy consumption and introduces other interviews.
