2. Thesis: Public desires secure, reliable, clean, sustainable & affordable energy supplies that are available on demand. Balanced environmental and energy development policies needed to meet energy demand growth forecasts. Oil and natural gas expected to contribute dominant share of energy supplies for > 20 years.

3. Energy Supply Issues Confusing & conflicting information about energy supplies Challenging oil & gas demand scenarios Natural gas: the challenge & opportunity of this decade Public policy pressure for renewable resources Petroleum industry squeezed by volatile markets, financial constraints, anti-hydrocarbon pressures, regulations and limited access to prospects

4. Challenging Oil Demand Scenarios Challenging Oil Demand Scenarios World Oil Demand Consumption in MMbopd 1993 - 99 2000-20 1993 1999 % 2000 2005 2020 % World 67.6 75.0 +11 % 75.6 84.6 118.9 56% U.S.A. 17.2 19.5 +13 % 19.7 21.2 25.8 31% Source: IEA and EIA Is 2020 target attainable?

5. Confusing Oil Supply Predictions Campbell - Laherrère – Deffeyes School Oil ultimate recoverable: 1,694* MMMb –Produced 849 –Remaining 845 MMMb –Reserves/Production 36 Years Oil production will peak and commence decline by the end of this decade. (* 2000 data excludes heavy oil & reserves growth.)

13. Oil Supply & Policy Issues No near-term decline in oil supplies –Crisis policies not required. Orderly transition to alternate sources. Reduce import dependency – boost production –Access to prospective lands –Investment incentives – tax credits, royalties –Efficient regulatory processes – reduce delays & costs Supply security: –Enhance Western Hemisphere policies & alliances
