Nuclear is Uneconomical

Existing technologies for more efficient end-use can save three-fourths
of U.S. electricity at an average cost of around 1 cent per kilowatt-hour--cheaper
than running a coal or nuclear power plant, let alone building one. Scores
of utilities have demonstrated and implemented at scale, rapid, large,
predictable, and extremely cheap "negawatts" (saved electricity). California's
per-capita use of electricity has been flat for 30 years while per-capita
real income rose 79 percent. Firms like DuPont, Dow, and IBM are saving
billions of dollars by cutting energy intensity, sometimes as fast as 6-8
percent a year.
My household saves 90 percent of electricity and 99 percent of space
and water heating energy with a 10-month payback using 1983 technology.
My team's redesign of some $30 billion worth of facilities in 29 sectors
normally finds energy savings of 30-60 percent in retrofits (paying back
in about 2-3 years) and 40-90 percent in new installations (typically with
lower capital cost). A detailed road map for eliminating U.S. oil use by
the 2040s, led by business for profit ("Winning the Oil Endgame"), shows
how to save half of U.S. oil and gas at average costs one-fifth and one-eighth
of current prices. Implementation is already underway. And each of the
60-80 known obstacles to implementing energy efficiency can be turned into
a business opportunity.
On the supply side, "micropower"--small-scale generation that emits
little or no carbon dioxide--provided one-sixth of the world's electricity
and one-third of its new electricity in 2005, meeting from one-sixth to
more than one-half of all electrical needs in 13 industrial countries.
The smaller of micropower's components, distributed renewable sources of
electricity, was a $56 billion global equipment market in 2006, while the
larger, combined-heat-and-power, was probably even larger. Micropower added
four times the electricity and 8-11 times the capacity that nuclear power
added globally in 2005, now produces more electricity than nuclear power
does, and is financed by private risk capital. Micropower plus "negawatts,"
which are probably about as big, now provide more than half of the world's
new electrical services.
Nuclear power is unnecessary and uneconomic, so we needn't debate its
safety. As retirements of aging plants overwhelm construction, global capacity
and output will decline (as they did slightly in 2006). Most independent
analysts doubt the private capital market will finance any new nuclear
plants. Even in the United States, where new subsidies would roughly repay
the next six units' entire capital cost, Standard & Poor's said this
wouldn't materially improve the builders' credit ratings. I expect this
experiment will be like defibrillating a corpse: It'll jump, but it won't
revive.
Nuclear power's market meltdown is good for global development: Saving
electricity needs around 1,000 times less capital and repays it about 10
times faster than supplying more electricity. Shifting capital to saving
electricity can potentially turn the power sector (now gobbling one-fourth
of global development capital) into a net funder of other development needs.
Further, an efficient, diverse, dispersed, and renewable energy system
can make major supply failures, whether caused by accident or malice, impossible
by design rather than (as now) inevitable by design.
The nuclear phaseout will also speed climate protection, because buying
negawatts and micropower instead will save 2-10 times more carbon per dollar,
and will do so more quickly. And it can belatedly stem nuclear proliferation,
too, by removing from commerce a vast flow of ingredients of do-it-yourself
bomb kits in civilian disguise.
This would make bomb ingredients harder to get, more conspicuous to
try to get, and far costlier politically if caught trying to get, because
the motive for wanting them would be unmasked as unambiguously military.
Focusing intelligence resources on needles, not haystacks, would also improve
the odds of timely warning. All this wouldn't make proliferation impossible,
but it would make things far more difficult for both recipients and suppliers.
Thus, acknowledging and accepting the market collapse of nuclear power
is an important step toward a fairer, richer, cooler, and safer world.
