Nuclear energy produces on an
exajoule scale for that money.
This may come as a surprise, but in many places, people consider
return on investment.
I certainly would love to have 300 billion dollars thrown at the problem of
energy, and I'd love to see solar power well supported, but to the limit it
can produce.
There is a fantasy among people who don't understand science, that if you throw money at something, it will work.
This link describes solar research from
almost 10 years ago. Solar PV power is 50 years old. It still doesn't produce a single exajoule of the 440 produced on earth. It doesn't even produce as much as ethanol, which produces 0.2 exajoules, in spite of
tens of billions in politically motivated subsidies.
http://gtresearchnews.gatech.edu/reshor/rh-sf97/solar.htmNuclear power produces 30 exajoules of primary energy on earth, about 9 of them in the United States. If the ethanol subsidy is ten billion, it is about 2% as efficient on return as an investment in nuclear power.
Nuclear power is safer, cleaner and cheaper than solar energy, especially in the case - routinely ignored by solar energy mystics = that involves batteries. However solar energy is still desirable, inasmuch as it can do what nuclear can't do, provide peak load power. This is a
synergy situation, not a competitive situation. Still the fact remains that the United States is now an impoverished country, having most of the world's debt. The reason that the world doesn't pull cards out of the house of cards is probably that everyone is frightened about what will happen to
everyone's big investment in the US. But it cannot last. Therefore the United States, to the meager extent that sober and
realistic people still exist there - and this would
not include the proponents of the ethanol shell game - make as many
wise investments as possible.
In fact, nuclear energy is the only new form of energy discovered and scaled to an industrial (exajoule) level in the last 100 years. It is the
only form of energy available on an exajoule that does not lead to widespread loss of life and the complete destruction of entire ecosystems. It is
dense energy, involving low mass investment and even lower
land investment. Thus investments in
nuclear energy are exceptionally wise. I have not deviated at all from my support of a massive government funded program to build 500 nuclear power plants in this country. Such an investment would represent
infrastructure and be the kind of investment that gives
returns. This does not mean that I would
oppose a few tens of billions of dollars invested in solar PV - maybe if we take the money out of the less promising ethanol subsidy.
One of the intellectual and moral dodges used by anti-nuclear people - not one of whom seems to understand either risk or energy - is to
ignore the scale of energy. It is nice to pretend if you're an ethanol lobbyist that 10 billion dollars is OK for a trivial petajoules, while 10 billion dollars for exajoules is somehow not. In fact the anti-nuclear squad routinely
inflates the size of nuclear subsidies while minimizing the other subsidies. The largest energy subsidy now in place is the occupation of Iraq, which is a subsidy not only in dollars, but in destroyed flesh.
Unfortunately global climate change is not a game.
I am still waiting to find out, by the way, why people are so obsessed with Strauss's 1954 phrase "too cheap to meter," as applied to nuclear energy. I have noted that there is not one renewable energy advocate on this site who can claim that
any form of energy is too cheap to meter. I note that the busbar cost of the Catawba nuclear station is possibly the
cheapest electrical energy produced on earth, especially if external costs are included. (That would be $18/MW-hr.) Solar energy in particular is still largely the province of rich people. Mostly it is wholly dependent on huge tax subsidies - and
still doesn't produce very much energy. It is politically popular, but not very productive. Poor people do not invest in big consumerist solar systems. In fact the entire renewable game is for middle class or rich spoiled brats.
Of those who posit the nuclear vs. solar question as "either/or" not one of these people seems to have a remote grasp of what energy is, where it comes from, what its risks are, how it is used and how it is produced. They seem to think it is produced by prayer.
I note that ethanol and biofuels and solar PV have all proved far less viable than their proponents claimed over the last five decades. In fact they are essentially
trivial industries, in spite of all the noise made about them.
