Profitable Solutions to Oil, Climate and Proliferation
Do you prefer to die of:
1. Climate change?
2. Oil wars?
3. Nuclear holocaust?
A stupid multiple-choice test
4. None of the Above
A stupid multiple-choice test
January 2009 McKinsey supply curve shows 70% of 2030 global greenhouse gas emissions can be abated at an average cost ~€4/tCO2e
By 2100, global CO2 emissions will
• triple — if we reduce energy/GDP by 1%/y
• level off — if 2%/y
• drop (stabilizing Earth’s climate) — if 3–4%/y
Profitable climate protection: How much can we do? How fast?
Yes!Feasible?

Efficiency first...
Vehicles use 70% of U.S. oil, but integrating low mass and dragwith advanced propulsion saves ~2/3 very cheaply
150 mi/h, 94 mpg
Hypercar Revolution SUV (2000)67 mpg (114 w/H2), 1-y payback
Toyota 1/X sedan (2007)Prius size, 1/2 fuel use, 1/3 weight
Bright IDEA 1-T 5-m3 van (2009)3–12×-efficiency plug-in hybrid, needs no subsidy

What “nuclear renaissance”? Here it is...

end 2009: 56(24% of 1979
peak), or4-odd % of newcapacity underconstruction
Of the 56 “under construction” reactors shown by IAEA at 9 Feb 2010: • 13 have been under construction for >20 years; 24 have no official start date; half are late• 41 are in China, India, Russia, or S. Korea; 6 of 10 starts in ’08 and 9 of 11 in ’09 are in China• All 56 are centrally planned, usually by authorities with a draw on the public purse• Zero are free-market purchases fairly compared or competed against available alternatives
New nuclear plants will scarcely be able to offset old units’ retirements
Nuclear is now the costliest of the no- or low-carbon resources

Carbon displacement at various efficiency costs/kWh
New nuclear saves 2–20× less carbon per dollar, ~20–40× slower, than efficiency and micropower investments
The cheapest and lowest-carbon sources save the most CO2 per dollar
