this lecture Global Energy Demand End of Peak Oil? Energy Sources, Energy Poverty, & Power Brief Side Trip to China What Energy Policy Can Do Challenges
? Global energy demand - who wants it? IEA: WEO 2010
What is the world using? ~80% ~1.7% oil gas coal nuclear hydro IEA: Global Statistics 2010
Oil: It doesn’t stand still - why?
End of peak oil? We are not running out...yet Recent discoveries in offshore areas have been very significant ~65% offshore Source: Offshore, IHS, May 1, /issue-50/international-e_p/global-overview_of.html?dcmp=ENL.OSWAR The Growing Gap
Is the age of cheap oil really over? before first oil crisis
Is the age of cheap oil really over? Not if we look at fuel cost as a % of disposable income U.S. can afford $90/bbl; maybe even $100/bbl Is the age of cheap oil really over? Not if we look at fuel cost as a % of disposable income U.S. can afford $90/bbl; maybe even $100/bbl before first oil crisis As a % of income, U.S. paying at $92/bbl (see previous slide) what it was before first oil crisis As a % of income, U.S. paying at $92/bbl (see previous slide) what it was before first oil crisis
Evolution of Energy Sources What has happened over time? Source: EIA
A clear pattern? “+HydrogenFusionOceanic Space Solar Energy transitions take time and, over last 200 years, have not meant giving up previous sources (not entirely) By 2050, we may still be using oil and even coal (though at reduced rates, hopefully) Energy transitions take time and, over last 200 years, have not meant giving up previous sources (not entirely) By 2050, we may still be using oil and even coal (though at reduced rates, hopefully)

Power generation has been, and will be, the most rapidly growing form of energy use ExxonMobil

gapminder energy use vs. time
Policy matters! Europe raised fuel taxes, used other measures to control energy demand after 1970s oil crises; energy consumption has been flat there and even declined; not in u.s. (demand left to free market, which began to affect energy use in late 2000s, during recent oil crisis) or in china Policy matters!

Quick summary Future energy use = developing nations The death of civilization has been exaggerated... Energy sources have diversified over time; since mid-20th c. they’re focus is electricity Energy poverty is real; 10 9s people remain without modern energy services China is central to the global energy future Policy is crucial!
challenges Energy Transitions take time, but Climate Change demands we act quickly: how to reconcile? There is a global need for investment - in new supply, innovation to reduce impacts, improve efficiency, advance existing alternatives, create new options; diversity of sources & options needed Also needed is cooperation among nations - to advance new pathways so that developing world won’t follow in historical steps of West (and now China) West needs to abandon myths about energy (‘energy independence,’ evil Big Oil, peak oil Apocalypse, nuclear fears, renewable energy as savior & essence of sustainability)
