Converting Heat to Work
Since pre-history we knew how to:
Work
Heat
Industrial Revolution to:
Work

Newcomen’s Steam Engine

Revolutionary Change
Transforms economy: textile production increases 150 fold and prices drop 90%
Transforms place: cities grow from 5% to 50%
Transforms family: parents leave home to work
Redimensions world: steam ship and railroad
Technology and population explode
Economic Explosion
From 1700-2000, per capita
US/Europe income grows from $600 to
$18,000 per year
Increases 30x!
Energy Revolution
Creates Modern World
Single Most Important Event in Human History
We’ve Come a Long Way…
Newcomen’s steam engine: 0.5%
Watt’s steam engine: 1%
Gasoline engines: 30%
Coal Rankine cycles: 35%
Turbines: 40%
Diesel engines: 50%
Combined-cycle turbine/Rankine engines: 60%
But Energy Conversion Largely Unchanged…

2. Employ combustion to release heat

Extreme Oil
“Oil sands and offshore drilling are both symptoms of the same problem: We’re running out of easy oil.”
Simon Dyer
Canada’s Oil Sands
Total resource ~ Saudi Arabia; #1 source of imported oil for US (22%)
GHG production from processing 400% greater than domestic oil, but well-to-wheel increase 5% - 15% greater
Surface mining (20%):
•
•
•
•
Strip earth’s surface for black goo called bitumen ; 2 tons of sand / barrel oil
1 barrel bitumen generates 500 gallons of liquid tailings
Tailing ponds cover 50 square miles; 3 million gallons/day leak into surrounding watershed
1,600 waterbirds died in a single tailing pond
In situ mining (80%):
•
•
Inject natural gas-heated steam into wells to drive bitumen to surface
Blend bitumen with natural gas liquids to transport and process
Deep Water Drilling
Gulf of Mexico
• 6,000 wells
•
•
Progressively deeper water
Deepwater Horizon: 5,000 ft water
Brazil’s Tupi Field:
• 7,200 ft water + 15,000 ft sandstone/rock salt
•
•
$1 million/day to operate platform
“The only political fight in
Brazil is over how to spend its future oil bounty and who gets the lions share.”

Consequences of Peak Fuel
• Rising demand and falling supply rapidly increases fuel prices
• Rising fuel prices reduce expendable income and cause recessions
• Rising fuel prices drain fuel importing economies and increase trade deficits
• Competition for dwindling supply increase national security risks
• Rising fuel prices support undemocratic regimes (Russia,
Middle East, Venezuela, etc.)

EEB Course Goals
Learn how to design buildings that are:
•
•
•
• Functional
(traditional engineering course)
Economic
(better engineering course)
Improve comfort / productivity
(enlightened engineering course)
E/3
(our course)
Addressing these global problems of resource and environmental constraints on the foundation of our modern economy will no doubt require:
•
•
•
•
Social reform
Economic reform
Political reform
Technological innovation
C = Pop x $/Pop x C/$ x E/$ x C/E
Business as usual case 2000-2050
•
•
•
•
• Pop grows at 1% from 275M to 450M is increase of 1.6
$/Pop grows at 2% is increase of 2.7
E/$ constant
C/E constant
C
2050

2000
Carbon stabilization case: C

2050
= 0.5 C
2000
= 1.6 Pop x 2.7 $/Pop x (E/$) / 4.3 x (C/E) / 2 = 0.5 C •
Continued development requires:
•
• Factor 4 increase in energy efficiency
Factor 2 reduction in carbon intensity of energy
2000
Atmospheric CO
•
2 concentration
Pre-industrial = 280 ppm
• Current = 380 ppm
• Best case target = stabilize at 500 ppm in 2050
(1 C above 2000 temperature)
Stabilizing at 500 ppm by 2050:
• World: C emissions constant at 7 GtC/yr (BAU = 14 GtC/yr)
• US: C emissions reduced 50% to 0.7 GtC/yr (BAU = 2.7 GtC/yr)
Possible by realizing “wedges”
