2a.1 Overview of Energy Issues • Energy decisions are influenced by supply and demand, politics, earmarks or “pork”, public interest or protests, availability, fuel source commodity changes, and economics • Ten-year construction time of a utility plant requires a reasonably stable market to justify construction loans • Uncertainty of the energy commodity markets can destabilize the perception of future energy needs • Proposed energy plants, even renewables, are usually met with opposition from potential neighbors (NIMBYs) or distant NGOs (nongovernmental organizations) • What’s a “CAVE”? (;-) 100120
2a.2.1 Recent Energy-Related Events (within ~1 year) • Still . . . : Pres. G.W. Bush wanted to drill for oil in Arctic National Wildlife Reserve (ANWR); environmentalists fighting potential pollution; estimates are that oil could satisfy US needs for six months to twelve years in only 10 years depending upon who estimates; could be held in reserve as part of SPR (Strategic Petroleum Reserve), opened Bristol Bay, Alaska for drilling 1/10/07 • Cape Wind still striving for first plant near Nantucket against much opposition www.capewind.org; • $20B invested in renewable energy vs. $150B in all global power – Erin Martinot 100120

2a.3 Worldwide Markets • Oil (and sub-products) and natural gas are marketed and shipped on the international commodity market • A commodity is somewhat indistinguishable regardless of source (fungible) -- Crude oil futures $76 on 1/21/2010 • Branding is sometimes used to attempt to get a better price -- like Florida orange juice vs. California OJ • If oil exporter decides not to sell to US, they sell elsewhere, and US buys from that country • OPEC (~15 countries) decides on total production based on price; allocated based upon reserves; estimated reserves may be kited to get more market share + Russian influence 100112
2a.3.1 Worldwide Markets • Gasoline is often the same to the tank truck distribution point, where additives color the gasoline with dyes or provide cleaning solvents, but mostly they enhance marketing content • Volatile fuel prices, but trends higher with time • Natural gas price shows winter demand cyclic peaks for Northern states heating; storm dependent • Utilities compete with homeowners on price; same with #2 heating oil, which competes with diesel 100120

2a.2.4.2 Crude Oil Prices • As supply and demand meet, high volatility results • $147 peak then fell to $33 and is now about $76 • Estimates (rumors) of $10 to $200/gallon are rampant • As gasoline reached $4/gallon, drivers cut back, changed routes, consolidated trips, bought smaller vehicles with better fuel economy • Prices below $3/gallon and yet the surplus of supply led to worldwide “demand destruction” and prices fell 100121
2a.2.4.2.1 Top Exporters • OPEC controls the prices of its members • World market also controls by supply and demand • The United States imports much of its foreign oil supply from Venezuela (12 to 15% of US needs) • Politics and union strikes dominate Venezuela oil market • Pres. Chavez is a socialist and anti-US, pro-Cuba; reelected 12/2006; inaugurated 1/10/07 • Pres.

2a.2.4.2.2 Iraq • $1.3B-$18B oil smuggling was known to UN Security Council but was not stopped according to Paul Volcker [Seattle Post Intelligencer, 12/27/2004]; different from “oil-for-food” (or oil-for-palaces) program that the UN also mishandled • Iraq has significant oil reserves (third) yet has a fraction of the World market • Greatest price effect is from psychological impact of turmoil on markets; panic drives speculators • Unstable population prevents normal production • Oil pipelines are readily sabotaged as they often are exposed above sand, isolated, and easy to bomb 100121
2a.2.4.2.3 Iran • Iran is developing nuclear power with Russian & Chinese help • Useful for ensuring more oil to export when prices soar • Greatest price effect is from psychological impact of turmoil on markets • Handy for nuclear weapons, too! • They sell oil on the world market under OPEC membership • Wanted to change OPEC valuation to Euros due to inflation of the US dollar but motion didn’t pass at OPEC meeting 100112
2a.2.4.2.4 Afghanistan • Afghanistan could be a route to bring petroleum pipelines from Turkmenistan in the north to the Arabian Sea for ease of water export • Turkmenistan has onshore and Caspian Sea oil fields • Turmoil in Afghanistan prevents development; tribal chiefs (politically incorrect: warlords) control remote areas • National government tenuous at best http://news.bbc.co.uk/olmedia/1585000/images/_1585197_afghan_targets2_300.gif 100121
2a.2.4.3 Natural Gas (NG) lngpedia.com • Clean-burning NG is the utility fuel of choice because of low emissions • Supplies are limited in N.
