RESOURCE USEAGE PROFILES OVER TIME
7
Note: Arctic Reserve estimated at 10-20 billion barrels, plus ‘new’ areas Canadian Reserves with Tar Sands ~ 100 billion barrels Russia has unknown additional quantities, Caspian, Siberia, Kamchatka Western USA Oil Shale resource >> Saudi Oil resource.
8
A piece of Oil Shale The USA has at least 3 Trillion barrels of Oil Equivalent of this resource.
9
Coal Carbon, water, impurities C + O 2 CO 2 HALF IS CLINKER
10
: COAL
11
US Coal Consumption Coal 22 QBtu (23%) 80% used by electric utilities
12
Major Coal-Producing States
13
Coal Anthracite 22 – 28 million Btu per ton Not plentiful Bituminous 19 – 30 million Btu per ton Most plentiful Subbituminous 16 – 24 million Btu per ton Low sulfur content Lignite (Brown Coal) 9 – 17 million Btu per ton Local value only
14
Coal Resources and Consumption Global Recoverable 1,000 billion tons Global Consumption 5.2 billion tons/year US Recoverable 274 billion tons US Consumption 1.1 billion tons/year
15
Global Coal Resources United States 25% Russia 16% China 12% India 9% Australia 8% Germany 7% South Africa 5%
20
A major drawback of fission energy: Diversion to bombs
21
CHERNOBYL REGION RADIOACTIVITY Potential for accidental or intentional containment failure.
22
Cleanup can be effected by biological and other means
24
ANY APPROACH WHICH REDUCES ENERGY USE IS USEFUL TO EXTEND OUR RESOURCES, I.E. CONSERVATION IS THE FASTEST METHOD TO GET NEW ENERGY
30
SOLAR ENERGY STORAGE, INEXPENSIVELY
36
Multi-junction Photovoltaics utilize much more of solar spectrum, MORE THAN 30% EFFICIENCY ALREADY ACHIEVED!
37
Highly Efficient Energy Utilization
38
Industrial scale Fuel Cells…
41
EFFICIENCY OF FUEL CELLS: CHEMICAL, NOT THERMAL PROCESS DIRECTLY USES ELECTRICITY WASTE HEAT MUCH LESS THAN OTTO CYCLE ENGINE MAX. EFFICIENCY HEAT ENGINE ~ 25-30% MAX. EFFICIENCY FUEL CELL ~75-80 % WASTE PRODUCTS DEPEND UPON FUEL WATER IN CASE OF HYDROGEN FUEL INTERSTITIAL HYDROGEN IN METALS, EQUALS ENERGY DENSITY OF GASOLINE…
43
ENERGY RESOURCE AND USEAGE DIRECTLY AFFECTED BY POPULATION AND STANDARD OF LIVING...
