- 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
7ALTERNATIVE FUELSAET 7410 - 5
- ALTERNATE FUELS LIMITATIONS
- THERE WILL HAVE TO BE MULTIPLE SUBSTITUTION

- FOR USING ENERGY FOR
- TRANSPORTATION
- FOR POWER GENERATION INDUSTRIAL HEATING
- FOR MANUFACTURING CHEMICALS PLASTICS
- FOR MINERAL AND METAL PROCESSING
- .AND MANY OTHER USES
8ALTERNATIVE 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?
9ALTERNATIVE 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!
10ALTERNATIVE 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!
11ALTERNATIVE 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
12ENERGY 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
13ENERGY 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!
14ENERGY 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
15ENERGY 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!

- 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!
20ENERGY 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!
21ENERGY RESOURCES NOWSUMMARY 10
22ENERGY 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

- CORN ? ETHANOL
- INDUSTRY CURRENTLY IN TROUBLE (1/2008)
- BIOMASS ? BIOETHANOL (NOT YET COMMERCIAL)

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

REPRESENTS A TOTAL OF 71 TCF OF METHANE OR A
3-YEAR SUPPLY FOR THE U.S.! - BUT EXPLORATION AND RECOVERY ARE VERY
CHALLENGING
26NEW 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?

32NEW 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??
33NEW 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
34NEW 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
35NEW 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
- (OR GLOBAL WARMING)
37CLIMATE 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?
38CLIMATE 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!
39CLIMATE 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
40CLIMATE 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)
41CLIMATE 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

- INVEST IN DEVELOPING AN UNDERSTANDING OF CC
- INVEST IN COMPENSATING FOR CC ADAPT!!
- COMMIT TO EDUCATING THE MEDIA AND THE PUBLIC

The Economist, June 2-8 2007
49CLIMATE 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.
50CLIMATE 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!
51CLIMATE CHANGE Prins and Rayner, Nature 44925

- 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!
