I fully share jmc's doubts on the
efficiency of markets. They are not even working for things which everybody understands, like food or lodging. What can you expect when dealing with sophisticated issues, especially innovation? It is trivial math that
truly free markets lead to monopolies as surely as gravity leads the marble to bottom of the bowl. We could also discuss the role of widespread information and IT. But honestly, business today (what makes really big money) is more about
information asymmetry and
moral hazard than innovation.
Machiavelli wrote that you have to choose between the worst and the lesser evil. The free market is a lesser evil, just as "democracy is the worst form of government, except for all those other forms...", from Churchill's words. You cannot avoid recurring crises without some kind of
control, either by the government or by someone else. What is more, efficiency is not a question of government vs. private, it is a question of relationship between the
elites and the
decision-makers, two different populations (Dr Bussard or Dr Nebel represent a scientific elite, decision-makers are powerful people in Washington).
The massive deployment of
nuclear power in France in the early 70's followed from a governmental decision which was all but democratic (the Parliament was not even informed).
Positive results overall, in my opinion. By the way, the French culture of state control has not much to do with the influence of Communists on the government. It is a legacy of King Louis XIV, the guy who reportedly declared "I am the State" (17th century's style of leadership!). Whatsoever, this lack of democracy is the original sin which the nuclear industry has to live with. You can still feel it today: in its management style (albeit slowly evolving), in the attitude of the public (it is vastly in favor of nuclear energy but has no confidence in the industry, at all). This is going to be a problem in the future.
Coming back to
ITER, I would consider myself sceptical, after reading
Sébastien Balibar, Richard Nebel and others. I know ITER is not likely to provide a solution during my lifetime but, at least, I do not think the ITER scientists are stealing my taxpayer money.
MSimon reminded us of the large
coal reserves. For sure, coal is going to take the lead if the markets play freely. Welsh mines are about to reopen (was Margaret Thatcher consulted ?). The scenario I have in mind (see below) is more pessimistic for coal than Msimon's (that would be interesting to understand why). Things are getting nasty around 2050-2060.
The red figures are the anticipated growth rates in world energy use. "A trouver" (the white area on the top right) means "To be found", in other words "We have a problem". GTep = Gtoe, ENR = renewables, Charbon = coal, Pétrole = oil. The source is an EDF R&D study, quoted in
manicore.com.
For the short term (say 2030 !), I'd rather rely on
fast reactors but I do not see much happening in the western industry. Go markets, do your duty! On the opposite, the Indian industry is moving much faster thanks to the very visible hand of their government.
