3 A. Energy Transitions Factors Behind Energy Transitions Peak Oil Energy Markets
4 1. Factors Behind Energy Transitions Shift from one dominant source of energy to another.Fossil fuels resources remain abundant.Transition linked with three factors:Demand:Growth in the amount of energy used incites finding more abundant energy sources.Price:Function of availability and demand.Higher prices incite finders alternative sources.Technology:Which types of energy forms are harnessed, processed, and delivered to the final consumers as well as where these activities take place.Better technology enables access to a wider variety of energy sources.
5 1. Factors Behind Energy Transitions Energy QualityDifference in the ability of a unit of energy to produce goods and services for people.One joule of electricity is not the same than one joule of coal.Combination of physical, chemical, technical, economic, environmental and social attributes that are unique to each form of energy.
6 1. Determinants of Energy Quality Energy DensityQuantity of energy contained per unit mass or volume.Power DensityRate of energy production per unit of the earth’s area. Usually expressed in watts per square meter (W/m2).Energy SurplusDifference between energy spent for procurement (extraction, transformation and delivery) and energy provided.IntermittencyTime availability of the energy source.Spatial distributionSpatial availability of the energy sourceSource: adapted from Cutler Cleveland (Lead Author);Peter Saundry (Topic Editor) .

11 2. Peak Oil Hubbert’s peak Geologist who predicted in the 1950s that oil production in the United States would peak in the early 1970s:US oil production peaked in 1973.Assumption of finite resource.Production starts at zero.Production then rises to a peak which can never be surpassed.Once the peak has been passed, production declines until the resource is depleted.Peak was estimated to be around :One estimate placed it symbolically at Thanksgiving 2005.Kuwait announced around Thanksgiving 2005 that the world’s second largest oil field (Burgan) has reached its peak.As of 2010, peak oil remains unconfirmed.

13 2. Peak Oil The case for Peak Oil Tar sands Largest oil fields discovered more than 50 years ago.The peak of oil discovery year was 1965.Some large discoveries in the 1970s (Alaska, North Sea), but none since then.The last year when more oil was discovered than consumed was 1980.Tar sandsLarge supplies, particularly in Canada (Alberta).A bottleneck in extraction and distribution.Require a lot of energy to extract and transform into a usable form.
14 3. Energy Markets Importance Used to be informal and locally oriented (e.g. wood).The growth in the use of fossil fuels created large and lucrative energy markets:Became national and global.Increasingly capital intensive.Contracts between suppliers and customers:Price, quantity and time of delivery (location).Permitted the emergence of large multinational corporations.Large financial markets:Financing activities such as exploration, exploitation, transportation and refining.

19 Challenges to energy markets Supply sources:Low diversity of energy sources. Foreign sources. Dependence on oil. Keeping natural resources for future use. Low oil prices instead of an energy policy.Affordability:Economies of scale. Waste involves less profits. Market forces and profit margins.Environmental impacts:Lobbying against environmental legislation.
21 1. Characteristics Nature Formed from decayed swamp plant matter that cannot decompose in the low-oxygen underwater environment.Coal was the major fuel of the early Industrial Revolution.High correlation between the location of coal resources and early industrial centers:The Midlands of Britain.Parts of Wales.Pennsylvania.Silesia (Poland).German Ruhr Valley.Three grades of coal.
22 1. Characteristics Anthracite (7%) Bituminous (75%) Lignite (18%) Highest grade; over 85% carbon.Most efficient to burn.Lowest sulfur content; the least polluting.The most exploited and most rapidly depleted.Bituminous (75%)Medium grade coal, about 50-75% carbon content.Higher sulfur content and is less fuel-efficient.Most abundant coal in the USA.Lignite (18%)Lowest grade of coal, with about 40% carbon content.Low energy content.Most sulfurous and most polluting.

25 2. Coal Use Coal use Thermal coal (about 90% use): Coking coal: Used mainly in power stations to produce high pressure steam, which then drives turbines to generate electricity.Also used to fire cement and lime kilns.Until the middle of the 20th Century used in steam engines (“Steam Coal”).Coking coal:Specific type of metallurgical coal derived from bituminous coal.Used as a source of carbon, for converting a metal ore to metal.Removing the oxygen in the ore by forcing it to combine with the carbon in the coal to form CO2.Used for making iron in blast furnaces (without smoke).New redevelopment of the coal industry:In view of rising energy prices.“Clean Coal” technologies, less ashes but same CO2.

29 Disadvantages of coal use 3. ChallengesAdvantages of coal useEasily combustible.Easy to store and transport.Relatively inexpensive.Wide availability of sources.Technologically simpler to use for energy generation.Disadvantages of coal useNon-renewable resource.Combustion by-products (e.g. SO2 and sooth).Coal mining is generally environmentally damaging.
30 C. Petroleum The Economic Importance of Petroleum Oil Reserves The Geopolitics of Petroleum
31 1. The Economic Importance of Petroleum NatureFormation of oil deposits (biotic perspective):Decay under pressure of billions of microscopic plants in sedimentary rocks.“Oil window”; 7,000 to 15,000 feet.Created over the last 600 million years.A-biotic perspective.Exploration of new sources of petroleum:Related to the geologic history of an area.Located in sedimentary basins.About 90% of all petroleum resources have been discovered.Production vs. consumption:Geographical differences.Contributed to the political problems linked with oil supply.
32 1. The Economic Importance of Petroleum UseTransportation:The share of transportation has increased in the total oil consumption.Accounts for more the 55% of the oil used.In the US, this share is 70%.Limited possibility at substitution.Other uses (30%):Lubricant.Plastics.Fertilizers.Choice of an energy source:Depend on a number of utility factors.Favoring the usage of fossil fuels, notably petroleum.

Economies of scaleEnergy contentHigh mass / energy released ratioReliabilityContinuous supply; geopolitically unstableStorabilityEasily storedFlexibilityMany uses (petrochemical industry; plastics)SafetyRelatively safe; some risks (transport)EnvironmentLittle wastes, CO2 emissionsPriceRelatively low costs
36 2. Oil Reserves “Scarce Abundance” The world oil production is currently running at capacity:Limited opportunities to expand production.20% of the world’s output comes from 14 fields.Ghawar:The world’s largest oil field; been on production since 1951.Produces approximately 4.5 million barrels of oil per day.55 to 60% of Saudi Arabia’s production.Expected to decline sharply (use of water injection).Could be 90% depleted.OPEC countries may have overstated their reserves:Production quotas are based upon estimated reserves.The larger the reserves, the more an OPEC country can export.In the 1980s, most OPEC reserves doubled “on paper”.Extraction continues while reserves remain the same(?).

48 3. The Geopolitics of Petroleum The Seven SistersPetroleum has for long been the object of geopolitical confrontations.The ability to fix the price and the production of oil was first established in 1928 by the Achnacarry Agreements.Between the “seven sisters” forming an oil oligopoly.Major oil multinationals (Exxon, Texaco, British Petroleum, Shell, Gulf, Standard Oil and Mobil Oil).Invested massively in extraction infrastructures, especially in the Middle East.Several producing countries, most of them in the Third World, wanted to have a more important share of the incomes of this lucrative market.
49 3. The Geopolitics of Petroleum OPECVenezuela, Iran, Iraq, Saudi Arabia and Kuwait founded the Organization of Petroleum Exporting Countries (OPEC) in 1960 at the Baghdad conference.Several other oil-producing nations joined thereafter the organization:Qatar (1961), Indonesia (1962), Libya (1969), Algeria (1970), Nigeria (1971), Ecuador ( , left the organization in order to avoid production quotas), The United Arab Emirates (1973) and Gabon ( ).From its foundation until the beginning of the 1970s, OPEC was unable to increase oil prices.Production was very important in non-member countries.Difficulty of OPEC members to agree on a common policy.

52 3. The Geopolitics of Petroleum A perfect storm?Booming oil prices after 2004.Prior oil spikes linked with short lived geopolitical events.The situation has changed at the beginning of the 21st century.A production issue:Petroleum extraction appears to be running at capacity.Demand, especially new consumers (China), is going up.A distribution issue:Limited additional tanker and pipeline capacity.A refining issue:Limited additional refining capacity.No refineries were built in the US since 1974.

54 D. Natural GasNature and UseAvailability and Distribution
55 1. Nature and Use Natural gas formation Composition Thermogenic: converted organic material into natural gas due to high pressure.Deeper window than oil.Biogenic: transformation by microorganisms.CompositionComposed primarily of methane and other light hydrocarbons.Mixture of 50 to 90% by volume of methane, propane and butane.“Dry” and “wet” (methane content); “sweet” and “sour” (sulfur content).Usually found in association with oil:Formation of oil is likely to have natural gas as a by-product.Often a layer over the petroleum.
56 1. Nature and Use Use Mostly used for energy generation. Previously, it was often wasted - burned off.It is now more frequently conserved and used.Considered the cleanest fossil fuel to use.The major problem is transporting natural gas, which requires pipelines.Gas turbine technology enables to use natural gas to produce electricity more cheaply than using coal.
57 2. Availability and Distribution ReservesSubstantial reserves likely to satisfy energy needs for the next 100 years.High level of concentration:45% of the world’s reserves are in Russia and Iran.Regional concentration of gas resources is more diverse:As opposed to oil.Only 36% of the reserves are in the Middle East.
60 Liquefied natural gas (LNG) Growth of the global demand has created needs to move natural gas over long distances.Liquid form of natural gas; easier to transport.Cryogenic process (-256oF): gas loses 610 times its volume.Value chain:Extraction.Liquefaction.Shipping.Storage and re-gasification.
