Energetics of Human Societies
• We are currently living off of stored energy capital of millions of years ago.
– The storage of organic matter in sediments and fossil deposits created the concentration of petrochemical fossil fuels
• There are low and high level societies which require different levels of energy consumption to maintain their needs:
– MDC are high
– LDC are low

Energy becomes an environmental problem
• The oil crises of the early 1970s marked a transition
where we began to realize the social, political and economics costs of such a heavy dependence on petroleum.
• Oil prices were low in the 1980s and 1990s but have steadily risen since thyen.

Energy Crisis or Energy Predicament?
Four dimensions of the energy predicament.
• Source Problems-how much do we have?
• Scale of energy consumption (population growth and economic growth)
• Global Policy and geopolitical problems
• Sink Problems

Commercial Energy
- 3 ways to define Energy:
• Non-renewable: exist in a fixed quantity in the earth’s crust and can be used up (oil, gas, fossil fuels).
• Renewable: resources in unlimited supply (Solar, wind, tides, hydro)
• Potentially Renewable: resources that can be used, but not faster than they can be replenished (biomass)
