Where the heck would we build these, I wonder?
I don't see this happening.

Devil wrote:Your poll is silly. You have 2 options, one OR the other.
I would rather powerdown, conserve, lower my standard of living, and switch to renewables than engage any more nuclear plants, whatever that choice might entail.
I wonder how many would agree with me?
I'll do a poll in the Energy Forum.

Ibon wrote: The choice to forego nuclear and "choose" re-newables would mean that we are limiting ourselves to a set supply of energy as received by solar flux. How is it practical or realistic to expect mankind to make this enlightened choice up front? We wont. This whole debate over nuclear or renewables is not about an energy choice. It is about choosing between sustainability and growth. So nuclear energy will allow us to avoid hitting the natural limits that peak oil presented mankind? So if we can’t rely on limited energy to impose limits on our growth than we have to fall back on natural disasters, global warming or disease? It seems we are always counting on some external force to modify our behaviour. That is by the way how nature has always worked. Nuclear allows us to continue to live on borrowed time until we willfully, of our own volition, through our own self devised design, limit ourselves to a sustainable paradigm. Can we do it?

1. They must address population growth.
2. They must address the global warming issue.
3. They must address the negative consequences of conservation efforts on the economy and efficiency gains increasing consumption.
4. They must address the economic issues of a no-growth economy and past debt.
5. They must be sustainable/ renewable and the least toxic to the environment.
6. And probably most important, they must be global in perspective.

No offense Ludi, but i would like to reveiw the math you used to reach that conclusion, you might be too low, or too high.

Do you not agree it is better than burning ff in terms of global warming?
Do you not think that the economic impacts from peaking oil are going to be significant? (I know you do). Is it therefore not preferable to minimize the economic impacts, reducing the chances for social chaos?
If so, then why on earth do you insist on bashing nuclear? Why are you not seeing the big picture in this case?

I'll answer for myself this question. Is nuclear putting out an immediate fire but planting the seeds of a greater inferno? I don't mean bombs here either.
Nuclear is an energy we can harnass that supplements the energy alreadly falling on the planet from solar flux. Fossil fuels did basically the same thing in that we pulled out of the ground stored solar energy like a battery to supplement the total available energy during the past 150 years. This supplemental energy permits us humans to develop societies that live beyond their carrying capacities since we don't know how to manage or design on our own limits to our growth. This is the bigger picture Father of Two and inherant in the nuclear solution are the seeds of this greater inferno. Using renewable energy sources forces us to live within the sustainable amount of energy that falls on the planet and avoids these imbalances.
orz wrote:Therein lies the problem.
It will allow us to continue to ignore the ecological limits.
Ecological limits would be irrelevant. If we had infite energy we could theoretically construct our own planet or grow food through hydroponics or any number of ludicrously energy intensive schemes that would support exponential growth.
And I don't know what it would take for people to understand ecological limits.
orz wrote:If overshoot is strictly a function of not enough energy, which in the basest form food, shelter and water are all functions of, then a source like fusion would negate the problem.
Dezakin wrote:And I don't know what it would take for people to understand ecological limits.
Probably actual limiting effects rather than fantasy assumptions of overshoot that will never be realized. Ecological limits postulated as such are the dreams of ecologists wed to the idea that nature is somehow going to punish mankind for our arrogance. It wont happen.
I dont know what it would take for ecologists to understand that most of their field is garbage sophistry.

Environmentalists and ecologists do not trust energy sources that add supplemental energy to human endeavours since humans act like all other critters and just multiply using this supplemental energy.
That is another reason by the way why we cant separate energy strategies from socio/political/religious/cultural stuff. We do so at our peril since we aren't capable to organize ourselves with a self imposed limits to our growth. At least until now.
Antimatter wrote: Living off the solar flux can mean anything from quantum dot photovoltaics to burning wood. Given that the solar flux is four orders of magnitude larger than our total energy use distinctions between received energy and so called supplementary energy from the ground appear somewhat arbitrary. Perhaps enviromentalists and ecologists who don't trust supplemental energy and push for an "ecological paradigm" just have a poor understanding of the Newtonian world view they love to deride.
Unlimited energy in a finite world still has limits

How many times do I have to say that with abundant enough energy we won't be stuck on this planet?
There's more places to live in this universe than "Mother Gaia" if one has sufficient energy to build the tools to get there and inhabit the area.
And in any case you seem to still be running under the faulty assumption of infinite exponential population growth, which simply isn't the only(or even most likely) scenario.
If you're going to use physical laws as shields to hide behind, then you better be prepared to accept the possibilities that these same laws allow as well.
There are no limits to our growth given a large and long-lived enough energy source.
