ALTERNATIVE FUELSAET 7410 - 4
  • ALTERNATE FUELS CHALLENGES
  • U.S USES 140 BN GALS GASOLINE/YEAR
  • THATS 425 MILLION METRIC TONS/YEAR
  • AND 63 BN GALLONS OF DIESEL FUEL
  • ABOUT 220 MILLION METRIC TONS/YEAR
  • AND 27 BN GALLONS OF JET FUEL
  • ABOUT 90 MILLION METRIC TONS/YEAR
  • DISPLACING EVEN 10 OF QUANTITIES THIS LARGE IS A
    MASSIVE CHALLENGE!
  • DISPLACING THE 25 TARGETED BY THE CURRENT
    ADMINISTRATION FOR 2020 IS PROBABLY IMPOSSIBLE

7
ALTERNATIVE FUELSAET 7410 - 5
  • ALTERNATE FUELS LIMITATIONS
  • THERE WILL HAVE TO BE MULTIPLE SUBSTITUTION
    STRATEGIES
  • NOT JUST FUELS BUT ALTERNATE ENERGIES IN
    GENERAL
  • FOR PRODUCING ENERGY
  • FOR USING ENERGY FOR
  • TRANSPORTATION
  • FOR POWER GENERATION INDUSTRIAL HEATING
  • FOR MANUFACTURING CHEMICALS PLASTICS
  • FOR MINERAL AND METAL PROCESSING
  • .AND MANY OTHER USES

ALTERNATIVE ENERGY SOURCES(OVERVIEW)
  • WHAT BENEFITS DO WE BELIEVE WE CAN ACHIEVE WITH
    AET?
  • SAVE ENERGYAND ENERGY COSTS?
  • FIX CLIMATE CHANGE?
  • FIX OTHER ENVIRONMENTAL PROBLEMS?
  • ACHIEVE ENERGY INDEPENDENCE?
  • AVOID RUNNING OUT OF OIL?
  • AVOID RUNNING OUT OF NATURAL GAS?
  • AND WHAT ABOUT WATER (SEE LATER)?
  • RELIEVE POLITICAL PRESSURES?

9
ALTERNATIVE ENERGY SOURCES(OVERVIEW)
  • WHAT PROBLEM(S) ARE WE SOLVING?
  • DO WE NEED AFs ( OR AETs)?
  • OR WILL WE JUST CLEAN UP FOSSIL FUELS AFTER ALL?
  • IF WE NEED AETs, WHAT ARE THE OPTIONS?
  • CAN WE GET THERE THROUGH BETTER CONSERVATION OR
    EFFICIENCY?
  • OR ALTERNATIVE POWERTRAINS (ENGINES)?
  • OR ALTERNATIVE FUELS
  • E.G., ETHANOL, BIODIESEL PLUS A FEW EXOTICS
  • OR WILL OUR COAL, NATURAL GAS, OIL, BE ENOUGH
    AFTER ALL.WITH CO2 CAPTURE?
  • THE ANSWERS ARE FAR FROM SIMPLE!

10
ALTERNATIVE ENERGY SOURCES(OVERVIEW)
  • WHY DO WE NEED AETs? - 1
  • WE HEAR FREQUENT, OFTEN HYSTERICAL CLAIMS THAT WE
    ARE WE ARE RUNNING OUT OF CONVENTIONAL FUELS.
  • THE U.S. IS RUNNING OUT THE REST OF THE WORLD
    (INCLUDING CANADA) IS NOT
  • BUTWHAT REMAINS IS HARD TO ACCESS AND PRODUCE
  • COSTS WILL CONTINUE TO TREND HIGHER BUT
    UNDULATE
  • MANY EQUALLY HYSTERICAL CLAIMS ABOUT ALTERNATE
    FUELS
  • WE WILL FOCUS ON THE FACTS
  • ARRIVAL AT MOST OF THESE FACTS IS AN EXERCISE IN
    THERMODYNAMICS
  • WHICH MOST LIKE TO AVOID!

11
ALTERNATIVE ENERGY SOURCES(OVERVIEW)
  • WHY DO WE NEED AETs ? - 2
  • CONCERN OVER INCREASING FUEL COSTS IS WORLD-WIDE
  • CAN WE FIND LESS EXPENSIVE FUELS?....PROBABLY NOT
  • CONCERN OVER FUTURE GLOBAL FUEL SUPPLIES
  • ISSUES ARE RELATED MORE TO POLITICS THAN RESERVES
    BUT NOT EXCLUSIVELY
  • CONCERN OVER U.S. ENERGY INDEPENDENCE
  • CAN WE MAKE LOW-COST FUELS FROM AN ALTERNATIVE
    RESOURCE THAT IS TRULY DOMESTIC, RENEWABLE, CLEAN
    AND PLENTIFUL?
  • WE HAVE TO TAKE ACTION BUT WE ARE CURRENTLY AT
    RISK OF MAKING SOME VERY BAD CHOICES

12
ENERGY RESOURCES NOWSUMMARY 1
  • WE WILL NOT RUN OUT OF OIL ANY TIME SOON
  • THE MEDIA HAVE TO SELL ADVERTISING SPACE
  • AUTHORS HAVE TO SELL BOOKS
  • GLOOM-AND-DOOM HYPE HELPS TO ACHIEVE THAT
  • WE ARE RUNNING OUT OF CHEAP CONVENTIONAL OIL
  • THE EASY-TO-PRODUCE DOMESTIC RESERVES ARE LONG
    GONE, ONLY THE DIFFICULT OIL REMAINS
  • BUTTHE QUANTITY OF RECOVERABLE RESERVES IS
    DETERMINED BY THE COST OF RECOVERY
  • THE HIGHER THE PRICE, THE GREATER THE AMOUNT
    RECOVERABLE ECONOMICALLY (PROFITABLY) A MOVING
    TARGET
  • FOREIGN EASY OIL IS STILL PLENTIFUL
  • E.G., IN LIBYA, PRODUCTION COST IS 2/BBL
  • COMPARE OIL SANDS AT 25/BBL
  • BUT POLITICAL SENSITIVITIES MAKE ACCESS DIFFICULT
  • ENERGY WILL REMAIN EXPENSIVE BUT
  • MORE UNCONVENTIONAL CAPACITY IS COMING ON LINE

13
ENERGY RESOURCES NOWSUMMARY 2
  • THE REAL PROBLEM WE USE TOO MUCH ENERGY
  • 5 OF THE WORLDS POPULATION 25 OF THE WORLDS
    ENERGY CONSUMPTION
  • 20.7 MILLION BBL OIL/DAY (60 OF WHICH IS
    IMPORTED)
  • 1 BBL 42 US GALLONS
  • 7.5 BILLION BARRELS/YEAR.
  • THE ENTIRE WORLD USES 28 BILLION BBL/YR. AND
    GROWING
  • 380 MILLION GALLONS GASOLINE/DAY
  • 140 BILLION GALLONS GASOLINE ANNUALLY
  • 90 BILLION GALLONS DIESEL FUEL PLUS JET FUEL/YR.
  • OF THAT, 63 BILLION GALLONS IS DIESEL
  • ADD 23 TRILLION CU. FT. (650 BILLION CUBIC
    METERS) OF NATURAL GAS ANNUALLY (ALSO ABOUT 25
    OF WORLD USE)
  • AND PRETTY SOON YOURE TALKING REAL ENERGY!

14
ENERGY RESOURCES NOWSUMMARY 3
  • THE US HAS A NATURAL GAS PROBLEM
  • IT USES 23 TRILLION CU.FT/YEAR, CANADA USES 3.5
    TCF
  • OFFICIAL U.S. RESERVES ARE CURRENTLY 187 TCF
  • THAT IS ABOUT AN 8-YEAR SUPPLYBUT
  • OFFICIAL RESERVES DATA ARE CONSERVATIVE
  • MUCH MORE GAS MAY BE COMING FROM THE ALASKA NORTH
    SLOPE AND THE MACKENZIE DELTA (UP TO 200 TCF IN
    TOTAL)
  • BUT THOSE PIPELINES NEED 10 YEARS TO APPROVE
    BUILD
  • SO WE ARE ALREADY IMPORTING LNG FROM OVERSEAS
  • EXPECT SHORTAGES BY ABOUT 2015
  • PRICES, WHICH HAVE GONE FROM 2.50 TO 14.00 AND
    BACK TO 7.50 IN 2-3 YEARS WILL REMAIN HIGH
    MIGHT REACH 20/MMBTU BY 2012.
  • CANADA IS NO BETTER OFF AND MAY HAVE TO RESTRICT
    EXPORTS TO THE US SOMETIME SOON

15
ENERGY RESOURCES NOWSUMMARY 4
  • FORECASTING OIL AND GAS RESERVES
  • M. KING HUBBERT CAME UP WITH THE HUBBERT CURVE
  • INITIALLY FOR OIL, BUT GAS CURVE IS SIMILAR
  • COAL, TOO..
  • SINCE THEN, MANY ADDITIONAL CURVES
  • CORRECT IN THAT ANY FIXED RESOURCE MUST FOLLOW
    SUCH DECAY CURVES, BUT
  • FOR VARIOUS REASONS, THESE HAVE IGNORED THE
    WORLDS RESERVES OF UNCONVENTIONAL OIL AND GAS
  • THEY HAVE ALSO IGNORED ENHANCED OIL RECOVERY
  • THE FORECASTS ARE THUS VERY PESSIMISTIC -
    SUPER-CONSERVATIVE JUST WHAT USGS AND THE SEC
    LIKE!

  • Campbell (2004)

19
ENERGY RESOURCES NOWSUMMARY 8
  • THE PROPHESIES OF DOOM START WITH M. KING HUBBERT
    (1956 AND LATER)
  • RESERVOIRS VARY WIDELY IN CHARACTER
  • SOME HAVE DELIVERED ONLY 10 OF THEIR CONTENTS
  • OTHERS, MUCH MORE
  • ENHANCED OIL RECOVERY TECHNIQUES CAN DELIVER 2-3X
    ORIGINAL RESERVES ESTIMATES.BUT NOT ALWAYS
  • ALL HUBBERT-TYPE PROJECTIONS HAVE IGNORED THE
    WORLDS RESERVES OF UNCONVENTIONAL OIL AND GAS
  • E.G., OIL SANDS, SHALE OIL, COAL? FUEL LIQUIDS,
  • THE FORECASTS ARE THUS VERY PESSIMISTIC -
    SUPER-CONSERVATIVE JUST WHAT USGS AND THE SEC
    LIKE!

20
ENERGY RESOURCES NOWSUMMARY 9
  • COAL GOOD NEWS AND BAD NEWS
  • THE GOOD NEWS IS THAT WE HAVE PLENTY OF COAL
  • 4,000 BILLION (4x1012) SHORT (2000 LB) TONS
  • 1,000 YEARS SUPPLY AT PRESENT USE RATES
  • 1012 SHORT TONS ARE ECONOMICALLY RECOVERABLE
  • CANADA HAS ANOTHER 2,000 ST, 800 RECOVERABLE
  • CURRENT PRICES PER MMBTU 0.85-2.50
  • COMPARE OIL _at_ 15.00 AND GAS _at_ 8.20 PER MMBTU
  • THE BAD NEWS IS THAT COAL PRODUCTION AND USE IS
    COSTLY DUE TO ENVIRONMENTAL CONCERNS OVER
  • MINE SITE TRANSPORTATION AIR AND WATER
    POLLUTION
  • NEED FOR CO2 SEQUESTRATION, PARTICULATES CONTROL,
    ASH DISPOSAL, ETC.
  • TOO MANY INEFFICIENT OLD ENERGY CONVERSION
    TECHNOLOGIES (E.G., STEAM RAISING AT 35)
  • DIRECT CONVERSION ? ELEC. POWER WOULD BE A WINNER!

21
ENERGY RESOURCES NOWSUMMARY 10
22
ENERGY RESOURCES NOWSUMMARY 11
  • THE US MAKES USE OF OTHER ENERGY SOURCES
  • NUCLEAR ZERO GROWTH FOR THE LAST 20 YEARS.
    WHY?
  • HYDROELECTRIC NO GROWTH POTENTIAL. WHY?
  • GEOTHERMAL CA ONLY IN US PLUS NZ, ICELAND,
    OTHERS
  • ALTHOUGH HEAT PUMPS ARE OK ALMOST ANYWHERE
  • WIND, SOLAR
  • VERY SMALL, SLOWLY GROWING (WIND BETTER IN
    EUROPE)
  • REMINDER ELECTRICITY IS NOT AN ENERGY SOURCE
    BUT AN ENERGY CARRIER
  • SOURCE ENERGY IS NEEDED FOR EFFICIENCY
    CALCULATION
  • THE US NEEDS MORE CAPACITY TO PRODUCE, TRANSMIT
    ELECTRICAL POWER AND MORE LOCAL AND REGIONAL GRID
    OFF-GRID DISTRIBUTED POWER GENERATION

23
ENERGY RESOURCES NOWSUMMARY 12
  • BIOMASS-BASED SOURCES
  • CORN ? ETHANOL
  • INDUSTRY CURRENTLY IN TROUBLE (1/2008)
  • BIOMASS ? BIOETHANOL (NOT YET COMMERCIAL)
  • BIODIESEL (FROM SOYBEAN IN US, RAPESEED IN
    EUROPE)
  • INDUSTRY CURRENTLY IN TROUBLE (1/2008)
  • DIRECT BURNING OR GASIFICATION OF BIOMASS (PAPER
    AND PACKAGING WASTES, WOOD CHIPS, CROP RESIDUES)
  • OK FOR HEAT, STEAM
  • BIOMASS OR WASTE ? LIQUID FUELS VIA GASIFICATION
    AND SYNTHOL/FISCHER-TROPSCH

24
NEW ENERGY RESOURCESNEAR TERM PROSPECTS
  • THE WORLD HAS VERY LARGE RESERVES OF
    UNCONVENTIONAL OIL
  • MUCH OF IT, FORTUNATELY, IN THE AMERICAS
  • CANADIAN OIL SANDS (TAR SANDS) IN ALBERTA
  • IN SERIOUS PRODUCTION SINCE ABOUT 1965, NOW ? 1
    BILLION BBL/YR
  • COMPARE US CONSUMPTION OF 7.5 BILLION BBL/YR
  • US SHALE OIL (PRIMARILY IN COLORADO, UTAH)
  • NO COMMERCIAL PRODUCTION YET MAYBE IN 10 YEARS
  • VENEZUELAS ORINOCO BELT OIL SANDS
  • LIMITED COMMERCIAL PRODUCTION POLITICAL

  • OFFSHORE OR IN PERMAFROST REGIONS OF US, CANADA,
    RUSSIA
  • ESTIMATED AMOUNTS ARE HUGE SEE LATER SLIDE
  • SYNTHETIC NATURAL GAS FROM COAL, BIOMASS, EVEN OIL

25
NEW ENERGY RESOURCESNEAR TERM PROSPECTS
  • METHANE HYDRATES
  • LOOSE LOW-T OR HIGH-P COMPOUND OF METHANE
    WATER, WELL KNOWN TO GAS PLANT OPERATORS
  • FOUND SUB-PERMAFROST OR SUB-SEA, JUST OFFSHORE
  • ESTIMATED METHANE HYDRATES IN PLACE WORLD-WIDE
    ARE ENORMOUS
  • OCEAN FLOOR 10,000 11,000 Gt(C)
  • ONSHORE ARCTIC 400 Gt(C)
  • ONSHORE ANTARCTIC UNKNOWN
  • NOTE 1 Gt(C) 1.33 BILLION MT OF METHANE AND 1
    MT METHANE 53,361 SCF. THUS JUST 1 Gt(C)
    REPRESENTS A TOTAL OF 71 TCF OF METHANE OR A
    3-YEAR SUPPLY FOR THE U.S.!
  • BUT EXPLORATION AND RECOVERY ARE VERY
    CHALLENGING

26
NEW ENERGY RESOURCESSYNTHETIC NATURAL GAS
  • DEFINED BY DOE AS AN ALTERNATE FUEL (!)
  • MANY ALTERNATIVES ONLY COAL GASIFICATION HAS
    REAL PROMISE (AND IS A FAMILIAR, IF OLDER,
    TECHNOLOGY)
  • REPLACEMENT OF 23 TRILLION FT3/YEAR WILL REQUIRE
    A MASSIVE INVESTMENT IN ONE OR MORE OF
  • METHANE HYDRATES
  • COAL GASIFICATION
  • THE LATTER IS MORE LIKELY, THE FORMER MORE
    ATTRACTIVE
  • SNG IS MORE LIKELY TO GET INDUSTRY INVESTMENT
    THAN H2
  • SOME NEW/PROPOSED USES OF NG
  • GASOLINE SUBSTITUTE (AS CNG) WIDESPREAD USE,
    ESP. IN WESTERN CANADA
  • CLEAN DIESEL FUEL E.G., CUMMINS WESTPORT
  • MANUFACTURING HYDROGEN (FOR WHICH NG MAY BE TOO
    VALUABLE AS NG)
  • REFORMER FUEL FOR SOFCs (WHICH USE BOTH THE H2
    AND THE CO)
  • DIRECT FUEL FOR FUEL CELLS? SOFCs OR MOLTEN
    CARBONATE?

27
NEW ENERGY RESOURCESNEAR TERM PROSPECTS
  • ENHANCED OIL RECOVERY
  • IN ITS SIMPLEST FORM, A WAY TO GET MORE OIL OUT
    OF OLD RESERVOIRS (E.G., CA HEAVY OIL, E. TEXAS)
  • A CLASSIC EXAMPLE OF THE RELATIONSHIP BETWEEN OIL
    PRICES AND ECONOMIC VIABILITY OF OIL RESERVES
  • EOR IS EXPENSIVE, JUSTIFIED ONLY IF OIL PRICES
    ARE HIGH TO VERY HIGH AS THEY ARE NOW
  • SURFACTANT INJECTION, STEAM DRIVE, WATER
    FLOODING, CO2 FLOODING, STEAM ASSISTED GRAVITY
    DRAINAGE (SAGD), FORMATION HEATING WITH IN-SITU

NEW ENERGY RESOURCESMID-TERM PROSPECTS
  • A FEW BIG SOLUTIONS HAVE THE POTENTIAL TO SOLVE
    THE ENTIRE NORTH AMERICAN ENERGY SUPPLY
    PROBLEM. THEY ARE
  • COAL
  • OIL SANDS
  • SHALE OIL
  • METHANE HYDRATES
  • SOLAR ENERGY (PV AND THERMAL)
  • BUT THEY ALL HAVE SEVERE LIMITATIONS. WHAT ARE
    THEY?
  • EMISSIONS, COST.OR BOTH
  • ANY OTHERS??

33
NEW ENERGY RESOURCESMID-TERM PROSPECTS
  • THE FOLLOWING OFFER ONLY PARTIAL SOLUTIONS
  • HYDROGEN
  • NOT AN ENERGY SOURCE, MUST BE MADE FROM ONE IN A
    COMPLEX, ENERGY-CONSUMING PROCESS
  • MANUFACTURE, TRANSPORTATION, DELIVERY AND USE TOO
    ENERGY-INTENSIVE IN TOTAL NO INFRA-STRUCTURE
  • REALISTICALLY, USE IS LIMITED TO FUEL CELLS
  • PROPOSED FUEL FOR IC ENGINES (BMW, FORD) CAN
    ALSO BE CO-INJECTED FOR EMISSIONS (SMOKE) CONTROL
    IN DIESELS EFFECTIVE BUT COSTLY
  • NO BUSINESS CASE FOR IT NOW - POSSIBLE THERE WILL
    BE AFTER OTHER OPTIONS HAVE BEEN EXHAUSTED IN
    ABOUT 2050-2075

34
NEW ENERGY RESOURCESHYDROGEN
  • NOT AN ENERGY SOURCE JUST A CARRIER
  • THIS FACT HAS A BIG IMPACT ON OVERALL EFFICIENCY
  • EXAMPLE FOR COAL ? ELECTRICAL POWER ? HYDROGEN ?
    FUEL CELL ? ELECTRICAL POWER ? FCV WHEELS
  • GENERATING TRANSMISSION EFFICIENCY 30
  • HYDROGEN ELECTROLYZER EFFICIENCY 65
  • HYDROGEN TRANSPORTATION, DISTRIBUTION,
    COMPRESSION DELIVERY TO VEHICLE TANK 80
  • OVER-THE-ROAD ACTUAL TANK-TO-WHEELS EFFICIENCY OF
    USE 30 (IC) OR 45 (FC)
  • SOURCE-TO-USE EFFICIENCY 5 (IC) OR 7 (FC)
  • NOT VERY IMPRESSIVE, ALTHO THIS IS A WORST
    CASE!
  • NOTE 1 KG H2 1 US GAL GASOLINE

35
NEW ENERGY RESOURCESBIO-BASED FUELS
  • BIOMASS-BASED FUELS
  • ETHANOL OK IN A 10 GASOLINE BLEND.BUT NOT AS
    E-85 (LOW MPG, QUALITY)
  • BIODIESEL OK IN A DIESEL BLEND ( 20 BD)
  • BUT BLEND QUALITY IS A MAJOR ISSUE
  • BIODIESEL BY HYDROGENATION LOOKS V. GOOD
  • BIOMASS CONVERSION TO LIQUID FUELS (BTL) BY
    FERMENTATION OR GASIFICATION
  • GASIFICATION TO SYNGAS ECONOMICS INDICATE COAL
    IS A PREFERRED SOURCE
  • BUT BIOMASS PRODUCES NO NET CO2, WHILE COAL
    REQUIRES CO2 CAPTURE
  • MORE ON THAT LATER.

CLIMATE CHANGE
  • CLIMATE CHANGE
  • (OR GLOBAL WARMING)

37
CLIMATE CHANGETHE BASICS
  • A JUSTIFICATION FOR MUCH AET ACTION
  • MOSTLY THAT AIMED AT CO2 REDUCTION AND INCREASING
    OUR ENERGY INDEPENDENCE
  • THE USUAL QUESTIONS ARE
  • IS IT REAL OR JUST POLITICS AS USUAL?
  • WHAT ARE THE REAL CAUSES OF CC?
  • IF WE CORRECT FOR THOSE THAT WE CAN CONTROL, WILL
    WE ACHIEVE ANYTHING USEFUL?
  • WHAT WILL IT COST TO ACHIEVE SOMETHING USEFUL?
  • WHAT ALTERNATIVE (OR ADDITIONAL) STEPS SHOULD WE
    BE TAKING TO DEAL WITH CC?
  • SHOULD WE BELIEVE EVERYTHING WE HEAR?

38
CLIMATE CHANGETHE BASICS
  • CLIMATE CHANGE
  • IT IS REAL AND VERY SERIOUS
  • WE KNOW THAT CC IS PARTLY MAN-MADE MAYBE AS
    MUCH AS 50 DUE TO ANTHROPOGENIC CO2, CH4, N2O,
    FLUOROCARBONS, OTHER EMISSIONS
  • THE BALANCE IS MOSTLY FROM NATURAL SOURCES
    VOLCANOES, FOREST FIRES, ROTTING VEGETATION AND
    WASTE, NON-CO2 WATER VAPOR SOURCES.....
  • WE SHOULD FIX WHAT WE CAN BY REDUCING FUTURE
    ANTHROPOGENIC EMISSIONS
  • BUT THERE MAY BE VERY LITTLE THAT WE CAN DO ABOUT
    THE PAST AND THE NON-ANTHRO PRESENT WE JUST
    DONT KNOW ENOUGH ABOUT REVERSING CC TO WRITE A
    PRESCRIPTION
  • MANY UNCERTAINTIES THE OCEANS, SURFACE WATERS,
    THE IMPACT OF INSOLATION, CHEMISTRY!

39
CLIMATE CHANGETHE BASICS
  • CAUSES OF CLIMATE CHANGE
  • ALMOST ALL OF OUR KNOWLEDGE IS BASED ON COMPUTER
    MODELS OF THE ATMOSPHERE.
  • MOST OF THESE INVOLVE SO MANY ASSUMPTIONS AND SO
    MUCH NOISE IN THE MEASURED INPUT DATA THAT THE
    OUTPUTS ARE ONLY QUALITATIVE.
  • WE KNOW WITH REASONABLE CERTAINTY THAT MAJOR
    CONTRIBUTIONS ARE MADE BY
  • CLIMATE CHANGE AGENTS IN THE ATMOSPHERE
  • SOLAR HEATING (INSOLATION)
  • SIGNIFICANT PROVEN CC AGENTS ARE CO2, H2O, CH4,
    N2O
  • BUT MAJOR CONTRIBUTIONS ARE MADE FROM TIME TO
    TIME BY PARTICULATE MATTER (DUST), SULFATE
    AEROSOLS, AND A FEW CHEMICALS PRESENT AT VERY LOW
    LEVELS SF6, FOR EXAMPLE THAT CAN EXERT A
    DISPROPORTIONATE EFFECT

40
CLIMATE CHANGETHE BASICS
  • CAUSES OF CLIMATE CHANGE
  • MORE SOLAR ENERGY REACHING THE EARTHS SURFACE
    IT HAS BEEN INCREASING STEADILY SINCE ABOUT 1850,
    THE END OF THE LITTLE ICE AGE.
  • THIS CONTRIBUTES ABOUT 1/3 OF CC, BOTH DIRECTLY
    AND THROUGH INCREASED WATER EVAPORATION
  • WATER VAPOR IS A CLIMATE CHANGE AGENT ABOUT AS
    EFFECTIVE AS CO2
  • CO2 AND CH4 (16x AS EFFECTIVE AS CO2) FROM
    NATURAL SOURCES, E.G.
  • ROTTING VEGETATION
  • FOREST FIRES
  • VOLCANIC ACTIVITY
  • WARMING OF PERMAFROST (ADDITIONAL DECOMPOSITION
    PLUS RELEASED METHANE HYDRATES)

41
CLIMATE CHANGETHE BASICS
  • CAUSES OF CLIMATE CHANGE
  • ANTHROPOGENIC (MAN-MADE) CONTRIBUTIONS ARE ALSO
    VERY REAL
  • COMBUSTION CO2 AUTOS, INDUSTRY, BUILDINGS
  • METHANE LEAKS FROM NATURAL GAS HANDLING SYSTEMS
  • LEAKS FROM CHEMICAL PROCESSING FACILITIES
  • USE OF CERTAIN CHLOROFLUOROCARBONS
  • USE OF NO-TILL FARMING GENERATES MORE CO2, USE OF
    NITROGEN FERTILIZER GENERATES N2O
  • THESE CONTRIBUTIONS HAVE BEEN ESTIMATED AT
    BETWEEN 5 AND 50 OF THE TOTAL. 5 IS FAR TOO
    LOW THE RIGHT NUMBER SEEMS TO BE CLOSER TO
    30-40.
  • THUS SOLAR 33, MAN-MADE 35, NATURAL 32
  • EVEN IF MAN-MADE 40, 60 IS STILL OUT OF
    CONTROL

CLIMATE CHANGE
  • WE DO NOT KNOW ENOUGH TO WRITE BIG CHECKS FOR CC
    CURES YET
  • MORE POLITICIANS PR THAN SOUND SCIENCE!
  • WHAT SHOULD WE DO?
  • FOCUS ON THE LOW-HANGING FRUIT ENERGY
    EFFICIENCY CONSERVATION TO LIMIT NEW CO2
  • WE ARE 50 YEARS TOO LATE TO FIX THE OLD CO2
  • INVEST IN DEVELOPING AN UNDERSTANDING OF CC
  • INVEST IN COMPENSATING FOR CC ADAPT!!
  • COMMIT TO EDUCATING THE MEDIA AND THE PUBLIC
    ABOUT THE FACTS OF CC
  • AVOID BEING PRESSURED BY CLIMATE CHANGE INTO BAD
    AET CHOICES OR MISGUIDED ACTIONS

The Economist, June 2-8 2007

49
CLIMATE CHANGETHE BASICS
  • CAUSES OF CLIMATE CHANGE
  • IF MAN IS ONLY 40 OF THE CC PROBLEM, CAN WE
    EXPECT TO CORRECT THE TOTAL PROBLEM?
  • ONLY PARTLY! THE REST WILL HAVE TO WAIT FOR
    NATURE.
  • DOES THIS MEAN THAT WE SHOULD DO NOTHING?
  • NO. BUT WE SHOULD NOT EXPECT TOO MUCH SUCCESS TO
    COME FROM OUR EFFORTS
  • WE SHOULD INSTEAD TAKE STEPS TO ADAPT TO - AND
    MITIGATE THE EFFECTS OF - CLIMATE CHANGE
  • SOME STEPS ARE BEING TAKEN NOW
  • FOR EXAMPLE, ANYTHING THAT REDUCES THE
    CONSUMPTION OF CARBON (IN FUELS) BOTH SAVES MONEY
    AND REDUCES CO2 EMISSIONS
  • BUT IT WILL NOT SOLVE THE PROBLEM.

50
CLIMATE CHANGETHE BASICS
  • HOW CAN WE HELP?
  • INCREASE EFFICIENCY OF ENERGY USE
  • PREFERABLY WHILE MAINTAINING PERFORMANCE
  • USE MORE CARBON-NEUTRAL FUELS
  • E.G., THOSE DRIVED FROM BIOMASS WHICH RECYCLE
    THE CARBON RELEASED DURING PROCESSING AND
    COMBUSTION
  • USE CARBON SEQUESTRATION TECHNOLOGIES
  • E.G., CAPTURE CO2 GAS FOR USE BY INDUSTRY
  • CONVERT CO2 INTO INERT MINERALS FOR DISPOSAL
  • THE ONLY WAY TO CONTINUE USING ESSENTIAL FOSSIL
    FUELS
  • PROBLEM THIS COSTS MONEY!!
  • THE CHALLENGE FINDING THE MOST COST-EFFECTIVE
    ROUTE TO CARBON EMISSIONS REDUCTION
  • BUT DONT EXPECT TO SOLVE THE WHOLE PROBLEM!

51
CLIMATE CHANGE Prins and Rayner, Nature 44925
p 973, 2007
  • KYOTO 1 IS A FAILURE ! (KYOTO 2 THE SAME!)
  • TOP DOWN, NOT MARKET
  • 150 PLAYERS WHEN 15 NATIONS REPRESENT 80 OF
    EMISSIONS.
  • CC IS A COMPLEX PROBLEM COMPARED TO ACID RAIN,
    OZONE HOLE, WMDs, NUCLEAR WEAPONS
  • EXAMPLE OF A PATH-DEPENDENT SYSTEM
  • GLOBAL INTERLACED ENERGY SYSTEM
  • VARYING NATIONAL DEVELOPMENT TRAJECTORIES
  • INVESTMENT IN MITIGATION FAR EXCEEDS THE
    INVESTMENT IN ADAPTATION
  • WE MUST FOCUS ON ADAPTATION!
