Unformatted text preview: Overview of the Energy Supply Portfolio J.W. Tester Sustainable Energy 10.391J, 22.811J, ESD166J, … Textbook readings: chapter 9, sections 7.1-7.2,and 8.1-8.3 plus important background in Chapters 1- 4 and 6 Overview of Our Energy Supply Portfolio ¡ Review of the current and projected demand for energy ¡ End-use energy forms and conversions ¡ Energy sources ¡ Scaling energy flows and prices on a common basis ¡ Energy chains and interconnectedness ¡ A portfolio of options ¡ Desirable characteristics addressing sustainability ¡ General energy resource characterization ¡ Renewable versus depletable resources ¡ Hubbert depletion curve for mineral resources ¡ Uncertainities regarding discovery and technology ¡ Role of energy storage 21 st Century Energy-Related Megatrends ¡ Increases in population lead to increasing demand for energy – significantly in LDCs, some in DCs ¡ Interest in developing indigenous energy resources grows ¡ Environmental and health concerns increase on all scales from local to global ¡ Increased electrification ¡ Infrastructure security concerns increase Fundamental Global Issues Dealing with reality ¡ population 6,000,000,000 ¡ land area 58,000,000 sq miles ¡ population density 100+ people/sq mile ¡ annual energy consumption 400 Quads - oil equivalent 72,000,000,000 bbl - coal equivalent 14,400,000,000 tonnes ¡ registered car and trucks 700,000,0000 ¡ electric generating capacity 3,000,000 MWe ¡ annual steel production 650,000,000 tonnes ¡ annual aluminum production 20,000,000 tonnes ¡ annual cement production 1,500,000,000 tonnes Progressing toward an asymptotic world ? ¡ Population - 6+ billion growing to 10 to15+ billion ¡ Total primary energy – 400 quads growing to 2000+ quads annually 73 billion growing to 365+ billion bbl of oil/yr ¡ Per capita energy per year – 10 BOE/yr-person growing to 25 BOE/yr-person ¡ Number of cars and trucks - 750 million now growing to 5 + billion ¡ MW electric generating capacity - 3.5 million MWe now growing to 15+ million MWe Other Fundamental Global Issues ¡ Carbon emissions may be affecting climate ¡ Health concerns over other emissions are growing ¡ Global fossil energy resources are not uniformly distributed The Big Energy Questions ¡ Can we satisfactorily reduce emissions and remediate wastes residing in our water and air basins? ¡ Can we offset changes being introduced by our consumption of fossil fuels? ¡ Can we significantly reduce our dependence on imported oil? ¡ Can nuclear, renewable, and other non-fossil energy resources be deployed quickly enough to make a difference? U.S. energy goals are focused maintaining a secure energy supply “ We need to inoculate ourselves against the risks of a disrupted energy supply due to deliverability constraints or price instabilities....
