Global Petroleum-Based Fuels and Feed-Stocks
• Global energy:• 40% electrical energy• 60% petroleum-based fuel
• Historically supplies of petroleum have been balanced with demand.• Anticipated decline between 2020 – 2040 according to the World Resources Institute.• As of 10 years ago:1
• 8 countries contain over 80% of global crude oil reserves.• 6 countries contain 70% of global natural gas reserves.• 8 countries contain almost 90% of global coal reserves.
