Nuclear energy: for or against?

Click For Summary

Discussion Overview

The discussion revolves around the pros and cons of nuclear energy, including its safety, waste management, and potential as a long-term energy solution. Participants explore various perspectives on nuclear power's viability compared to fossil fuels and renewable energy sources, as well as the future of energy production, including nuclear fusion.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants argue that nuclear energy is a clean and efficient power source that can supply large amounts of energy to cities, while others express concerns about the dangers associated with nuclear disasters and radioactive waste.
  • There is a viewpoint that the risks of nuclear energy have been exaggerated by the media and environmentalists.
  • Some participants advocate for the construction of new nuclear power plants, emphasizing the need for proper safety measures to mitigate risks.
  • Others highlight the limitations of renewable energy sources and the necessity of nuclear energy as a transitional solution until fusion technology becomes viable.
  • Concerns are raised about the waste produced by fusion energy, with some arguing that it is less problematic than fission waste, while others counter that fusion still generates radioactive materials.
  • Several participants discuss the potential for nuclear energy to serve as a temporary solution while transitioning to fusion, which they believe could be cleaner and more sustainable.
  • There are differing opinions on the longevity of fossil fuels, with some asserting that there is enough coal for centuries, while others claim that renewable energy sources like solar could meet future energy demands.

Areas of Agreement / Disagreement

Participants express a mix of support and skepticism regarding nuclear energy, with no clear consensus on its overall safety, necessity, or future role in energy production. Multiple competing views remain, particularly regarding the transition to fusion and the management of nuclear waste.

Contextual Notes

Participants reference various statistics and historical contexts regarding energy sources, but the discussion includes unresolved assumptions about the feasibility and safety of nuclear energy and fusion technology.

Yes they do; I include the capacity factor for http://rredc.nrel.gov/solar/pubs/redbook/PDFs/AZ.PDF: 25% or 6 kWh/m^2 out of a 24 hour day (that's measured over many years: winter/summer, night/day, sunny/cloudy). At 100% CF we'd be talking about 150 MW/km^2 (total ~2900 km^2) instead of the 20-30 MW/km^2 (~22000 km^2).* I was mostly addressing Argentum Vulpes' comment that one would have to "cover" over the southwest US to supply the US load w/ solar PV. Hardly.
Um...are you responding to the right post train there? I never mentioned or responded to any land area calcs, only solar capacity stats.

Did you forget the sarcasm smiley there my friend.
I was kinda wondering the same thing. It can be variable with CNN*, but there's the additional issue here of whether one should give both sides equal treatment if one side is science and the other crackpottery.

*CNN is owner/partner of "mother nature network" and "treehugger.com" and has featured some truly awful envirocrackpottery in content-sharing on cnn.com, including anti-nuclear crackpottery.

[edit] So I'm watching it now...maybe this should get its own thread...

The first segment discusses the viewpoint that there is no nuclear waste issue, a viewpoint I've been advocating for years. Key points:
1. Yucca mountain is a pointless, fantasy boondoggle. Paraphrase: 'what is this future 500 years from now it is meant to protect?' In other words, it is meant to protect something that is speculative and in the distant future. Why bother?
2. Nuclear waste is not particularly harmful and is extremely limited in volume. They showed some being stored in a parking lot at a nuclear plant. Just sitting there, harming no one. And available for recycling if we choose to do it.

Second segment is about France's nuclear power:
1. France built their nuclear society quickly.
2. France's carbon footprint is half what Germany's is per capita.
3. France's electricity is the cheapest in Europe.

And nuclear weapon non-proliferation:
1. We're buying Russia's nuclear weapons (I had no idea) to power our reactors (I did know that). 10% of our electricity/half of our nuclear power comes from Russian nuclear weapons. Some environmentalists are worried that nuclear power can lead to nuclear weapons, but currently, it is the other way around.

Wow, that was it? To call it a "documentary" is generous; was it even a half hour long? But it was short/concise, accurate and clear, so I'll have to give it some props for that!

Post-show discussion:
Environmentalist says it was one-sided because it didn't discuss "renewable" energy (duh; it wasn't about renewable energy) and claims 80% of our power can be renewable by 2050. The nuclear expert responds that that's "silly"; despite 25 years of heavy government subsidy, non-hydro renewable is only 2% of global energy production, while global energy production grows by 2% a year. Burn.

Hmm...maybe what CNN showed me was just an excerpt, because there was another clip shown that wasn't in what I saw.

They are saying that oil companies are pushing alternative energy because they know it is not a threat to them, but nuclear power is.

"those numbers don't consider the low capacity factor ..."

"those numbers" does not refer to area calculations above, based on capacity factor?

No, I quoted what I was responding to: post #139, which is about gross capacity only and was addressed to me (and I quoted the entire post). Your area calculations were in post #140, and were addressed to nikkkom.
