What if Germany had invested in nuclear power?
Germany’s decision to phase out nuclear power in favor of renewables is examined through trade-offs between radioactive waste, coal reliance, and the economics of large-scale energy transitions. Commenters contrast nuclear’s low CO₂ emissions and reliability with unresolved long-term waste storage issues and past mismanagement, while noting that Germany’s early subsidies helped make wind and solar cheap but were implemented imperfectly. Broader themes include energy security, the political left–right framing of nuclear vs. fossil fuels, and whether France’s nuclear-heavy model or Germany’s renewable-heavy path offers a more sustainable template.
Nuclear Waste: Scale, Risk, and Management
- Debate over whether “giant piles” of nuclear waste are worse than coal waste; some argue nuclear volumes are tiny per person, others note totals (e.g., ~10,000 tons/year for a fully nuclear U.S.) still feel large.
- Disagreement on what counts as “waste”: some say spent fuel only; others stress intermediate‑level and other high‑level waste also need long‑term storage.
- Breeder and fast reactors are cited as able to use “waste” as fuel, but are described as still experimental, slow‑moving, and not solving all waste types.
- Ideas like deep‑sea dumping or launching to space are floated but not examined in depth.
Germany’s Experience and Attitudes
- Past failures like the Asse II leaking waste dump strongly shape German public opposition to nuclear, beyond Chernobyl fears.
- Germany still lacks a permanent repository; official processes may run into the 2070s.
- Some see Germany as capable of safe operations but acknowledge poor waste handling and major infrastructure/megaproject issues.
- Claim that Germany is “outsourcing” nuclear to neighbors is contested; export/import balance is brought up to argue Germany is mostly a net exporter.
Nuclear vs Renewables: Costs, Systems, and Security
- One side: nuclear is dense, reliable baseload, safer than coal, and necessary until better storage exists; shutting it down while burning coal is framed as irrational.
- Other side: renewables are now cheaper, nuclear is “20th‑century tech,” and new plants are too costly and slow; Germany’s early subsidies helped push solar/wind down the cost curve globally.
- Thread cites Lazard analysis to argue that firming intermittent renewables can double or triple their effective cost in some grids; others stress LCOE for wind/solar is already very low.
- Concerns about Chinese fossil‑powered solar manufacturing vs. claims that energy payback for panels is short and fossil use will decline.
- National‑security angle: nuclear fuel cycle is partly dependent on Russian and Chinese conversion/enrichment capacity.
Politics and Policy Design
- Debate over whether coal/gas support is “center‑right,” vs. nuclear skepticism as historically left‑wing.
- Some argue both nuclear and renewables paths in Europe (France vs Germany) were badly implemented, not intrinsically flawed.
- Energiewende’s long‑term feed‑in tariffs are seen as both costly and instrumental in scaling global renewables; later cuts hurt Germany’s own solar industry.
Alternative Structural Ideas
- One commenter proposes large‑scale de‑urbanization and energy‑efficient single‑family homes as a major demand‑reduction strategy; others doubt its feasibility and data support.
- Dutch and Russian gas stories are used to illustrate how energy policy bets (on future nuclear or on fossil export windows) can go wrong.
