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…

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.)

$/Pop increases by 4x

E/$ constant

C/E constant

C

2050

= 1.5 Pop x 4 $/Pop x E/$ x C/E = 6 C

2000

 Carbon stabilization case

Thank you!

EXTRA SLIDES

What to do?

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

Doing the Math: US

 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

= 1.6 Pop x 2.7 $/Pop x E/$ x C/E = 4.3 C

2000

Carbon stabilization case: C

C

2050

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

Stabilization Wedges

 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”
