Growth in german wind capacity is slowing. Soo... then the plan is to keep on with lignite and gas? Am I missing something?

Don’t import Reddit’s extremely ignorant takes on nuclear power here, please. Nuclear power is a huge waste of money.

If you’re about to angrily downvote me (or you already did), or write an angry reply, please read the rest of my comment before you do. This is not my individual opinion, this is the scientific consensus on the issue.

When it comes to generating electricity, nuclear is hugely more expensive than renewables. Every 1000Wh of nuclear power could be 2000-3000 Wh solar or wind.

If you’re about to lecture about “it’s not possible to have all power from renewable sources”, save your keystrokes - the majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable. Again, this isn’t my opinion, you can look it up and find a dozen sources to back up what I am writing here.

This is all with current, modern day technology, not with some far-off dream of thorium fusion breeding or whatever other potential future tech someone will probably comment about without reading this paragraph.

Again, compared to nuclear, renewables are:

  • Cheaper
  • Lower emissions
  • Faster to provision
  • Less environmentally damaging
  • Not reliant on continuous consumption of fuel
  • Decentralised
  • Much, much safer
  • Much easier to maintain
  • More reliable
  • Much more responsive to changes in energy demands

Nuclear power has promise as a future technology. It is 100% worth researching for future breakthroughs. But at present it is a massive waste of money, resources, effort and political capital.

Nuclear energy should be funded only to conduct new research into potential future improvements and to construct experimental power stations. Any money that would be spent on nuclear power should be spent on renewables instead.

Wow I'm surprised to see people are actually downvoting you and arguing about this. It's common knowledge that the cost, impact, and build-time of new nuclear plants makes them a poor choice for energy. Not only is wind/ solar cheaper, it's faster to build.

It's also common knowledge that the more often you build something, the lower its price tends to go as that knowledge spreads. It's part of the reason it's so expensive to build trains in the US and so cheap in South Korea and Spain.

This famously isn’t true for nuclear power. It just keeps getting more expensive.

The French nuclear case illustrates the perils of the assumption of robust learning effects resulting in lowered costs over time in the scale-up of large-scale, complex new energy supply technologies. The uncertainties in anticipated learning effects of new technologies might be much larger that often assumed, including also cases of “negative learning” in which specific costs increase rather than decrease with accumulated experience.

And this research was done before Fukushima, which increased costs even further.

This is just more reasons to prioritise the already cheaper renewables, isn't it?

[-] regul@lemm.ee 3 points 1 year ago

I feel like climate change makes this a yes and situation.

[-] tryptaminev@feddit.de 3 points 1 year ago

It is not a yes and, because urgency favors renewables even more. If it wouldn't be for bureaucratic and political hurdles, from planning to operation is about 2 years for onshore wind and solar sites. For things like retrofitting a small solar plant on a residential or industrial building it can be as short as three months and for balcony solar power as a small hobby project it is as little as a day of planning + the delivery time + a day of installation.

Nuclear plants on the other side take minimum a decade, more likely two decades and that is despite strong political and bureaucratic support that is needed to get it going at all. Otherwise with citizens protest it would stay in court indefenitely.
