Energy Consumption and Consequences
The Politics of Oil
World oil reserves in 2003
Global Distribution of Oil
The Oil Age
1900 1920 1940 1960 1980 2000 2200
Oil discovery and consumption
Remaining fossil fuel supply in years
Based on production in 2000
The Age of the Fossil Fuels
What are Oil and Gas?
OctaneNatural Gas
Liquid hydrocarbons
Benzene
The formation of Oil
The Oil Window
Oil migration and entrapment
Oil traps
The origin of coal
The formation of coal
Phanerozoic Ice Ages and CO2
At least five ice ages in Earth history including Neoproterozoic (850-630 Ma) Snowball Earth
Current CO2 levelsrelatively low in the context of Earth history
Milankovitch Cycles and the Quaternary Ice Age
Current Ice Age started at 2.6 Ma
Earth has been in an interglacial for 11,000 years
Global Warming - Current Models
Causes of Current Global WarmingCO2, Solar Activity or Both?
Other Sources of Energy
Estimated world energy reserves
A world dominated by Nuclear Energy?
1 Quad = 1 quadrillion BTU
1 BTU = 252 calories
Nuclear Energy
Chain reaction
Neutron collides with U235 forming krypton and barium and releasing more neutrons + vast amounts of energy
Formation of Unconformity-type Uranium Deposits
2U6+ + + 2H2O + C = 2U4+ + 2H+ + CO2
U4+ + O2 = UO2 (Uraninite)
Tidal and hydroelectrical energy
Geothermal Energy
Geothermal Home Heating
Heat Pump
Energy Sources
