I agree it’s safe but idk it’s the best we currently have, I think that probably depends on locale.
Solar and wind (and maybe tidal?), with pumped hydro energy storage is probably cheaper, safer, and cleaner… But it requires access to a fair bit more water than a nuclear plant requires, at least initially.
But nuclear is still far better than using fossil fuels for baseline demand.
Land usage is also a huge concern with hydro power. Pumped hydro storage means permanently flooding an area to create the reservoir, which carries many above and beyond just the destruction of whatever was there before. The flooded land has vegetation on it, enough is now decaying under water. This can release all sorts of unpleasantness, most notably mercury.
I agree it absolutely has problems and I hope we come up with a better solution in the near future.
But it’s currently the lesser evil. Even though nuclear plants don’t need a lot of fuel, getting that fuel is still typically more damaging than creating a water reservoir, or using an existing natural reservoir.
Land usage is what makes nuclear the most ecologically sound solution. Solar and wind play their part. But for every acre of land, nuclear tops the chart of power produced per year. And when you’re trying to sate the demand of high density housing and businesses in cities, energy density becomes important. Low carbon footprint is great for solar and wind but if you’re also displacing ecosytems that would otherwise be sucking up carbon, its not as environmentally friendly as we’d like.
Are you displacing whole ecosystems, though?
How much do wind farms affect grasslands and prairies, etc? They’ll have an impact for sure, but it’s not like the whole place gets paved over.
And solar can get placed on roofs of existing structures. Or distributed so it doesn’t affect any one area too much.
I have to admit idk much about sourcing the materials involved in building solar panels and windmills. Idk if they require destructive mining operations.
I imagine that a nuclear reactor would require more concrete, metal, and rate earth magnets that a solar/wind farm, but idk. I likewise don’t know the details about mining and refining the various fissile material and nuclear poisons.
The other advantage of renewables is that it’s distributed so it’s naturally redundant. If it needs to get shut down (repairs, or a problem with the grid) it wont have a big impact.
I like nuclear, and it’s certainly the better choice for some locations, but many locations seems better suited for renewable
Right, like I’ve said it’s not the best solution everywhere. But where it’s an option (which is many places) it’s a better one. Not solar in the case of grasslands, probably wind. But you get the idea.
I’m not against renewables but utilizing them as our main source of energy just is not practical for long term, there are serious ecological issues that have been sidelined because of global warming/climate change. Things like rooftop solar only become viable in low density housing, but low density housing is also not good use of land.
I agree it’s not the ideal solution, but it’s better than most solutions we have, depending on location.
Rooftop solar doesn’t only need to be on residential buildings, it can also be on industrial and commercial buildings, which take a significant land area.
One last benefit of most renewable energy that is related to its distributed nature: it’s easy to slowly roll out update and replacements. If a new tech emerges you can quickly change your rollout plan to use the new tech, and replace the old tech a little bit at a time, without any energy disruption.
With mega-projects like nuclear reactors, you can’t really change direction mid-construction, and you can’t just replace the reactors as new tech comes online, because each reactor is a huge part of the energy supply and each one costs a fortune.
Also, according to the doc you shared of land-use, in-store wind power is nearly the same as nuclear, since the ecology between the windmills isn’t destroyed.
So while I agree that nuclear absolutely has a place, and that renewables have some undesirable ecological repercussions, they’re still generally an excellent solution.
The elephant in the room, though, is that all the renewable solutions I mentioned will require energy storage, to handle demand variation and production variation. The most reliable and economically feasible energy storage is pumped hydro, which will have a similar land usage to hydro power. On the upside, although it has a significant impact, it does not make the land ecological unviable, it just changes what ecosystem will thrive there - so sites must be chosen with care.
So I work for a large enterprise type software with a database. And because our installer is trash, we don’t trust clients to do it. It’s very common for the installer to error out with SQL error messages and we have to go fix things in the database. Think stupid things like if a value is null in one field, installer crashes.
So they call in, get paperwork for a test upgrade (we require they upgrade a test database first), then after they email that paperwork and it’s approved by management, the call to schedule the test appointment happens. Then 3 days before the actual appointment, we can call them and transfer via Bomgar the files they need. Because we don’t wanna give them the needed files early for… reasons never explained properly to me.
Then the actual install/upgrade call happens.
Then we do it all over again for the live.
Welcome to corporate policy that’s been building over 20 years, and never cut back. Things get added to the install process, never removed.
Well for the same reason lots of not great software is used.
It was once the best (or only) in the market, and now it’d cost literally millions of dollars to change in training/conversion/hardware changes. As long as we keep above the “We cause less damage than a change costs” folks stay.
