5 World total primary energy supply by fuel **Other includes geothermal, solar, wind, heat, etc.

6 World oil consumption by sector *Other sectors comprises agriculture, commercial & public service, residential and non-specified.

7 World primary energy demand by fuel Their share in total demand will increase from 80% to 82% IEA, WEO 2004 Fossil fuels will continue to dominate global energy use. They will account for around 85% of the increase in world primary demand.

8 Transport oil demand and GDP, IEA,WEO 2004

9 Regional shares in world primary energy demand Two-thirds of the increase in global energy demand will come from developing countries By 2030, they will account for almost half of total demand, in line with their more rapid economic and population growth. IEA, WEO 2004

13 Basically since we have futures markets in oil, the expectations on long term price of oil were extraordinarily stable - at around 20$/bl. That meant that, at all times, and whatever the actual spot price was, oil prices were expected to come back (upwards, or downwards, depending on where it would be then) to that level. The view of the market on future prices of oil has changed in the past 2 years. The market expects oil prices to still be around 6070$/bl 5 years from now, and not to drift down to 20$/bl or somewhere in between. 11-S Irak War

21 Depletion

22 AIE: Decline rates range from 5% to 11% per year. By 2030, most oil production worldwide will come from capacity that is yet to be built World Energy Outlook 2004

40 In ads that Chevron has been running in major newspapers and magazines, we are told that we the world is using two barrels for every one it finds. "One thing is clear: the era of easy oil is over," say the ads.

51 CONCLUSIONS The future of global oil supply: plenty of challenges and uncertainties No agreement on available resources and reserves No agreement on the date of peak oil ( ?) Increasing dependence from Middle East and OPEC Geopolitics: the new great game Trillions in investments (70% E&P) High-risk of temporary supply disruptions Tight supply/demand Price volatility The era of cheap and easy oil is over A new situation that along with global warming demands a new energetic model
