Context

Energy Future: Context Fossil fuel is plentiful (and inexpensive) –Oil supply is in 10s of years (Lewis*: 40-80) –Gas supply is over 100 years (Lewis: ) –Coal supply is several 100 years (Lewis: 200– 2000) 85% of the world’s energy is supplied by fossil fuel No new nuclear energy generation capacity has been added in decades Renewable energy sources contribute an extremely small portion of the overall world requirement Economic development has been and continues to be dependent on “cheap energy” *Nathan Lewis reference is cited frequently.

More Facts 20% of U.S. Oil comes from the Persian Gulf –40% comes from OPEC nations; –70% of U.S. oil from outside the U.S. –U.S. consumes 26 % of the world’s total petroleum China is next with 10% Russia uses 7% Oil prices: –Peak at $59.41 in 1980 (in 1996 dollars) –2001 price: $22 –Retail energy price of gasoline in Japan ($3.40) and Germany ($3.35). Per capita consumption of energy: –U. S. 342 BTU; Germany/Japan 170; China 30 Source: EIA
