The world has experienced its hottest day on record, according to meteorologists.
The average global temperature reached 17.01C (62.62F) on Monday, according to the US National Centres for Environmental Prediction.
The figure surpasses the previous record of 16.92C (62.46F) - set back in August 2016.
That’s a false dichotomy. There are more power sources than coal and nuclear.
Also electricity generation is not the only source of emissions. Car traffic, cruise ships, aiplanes, all need to be reduced and can’t just be replaced by nuclear power.
In theory, yes. In practice, nuclear plants that are shut off are almost always replaced with fossils, with the specific fossil fuel of choice often being coal.
Energy is not something where you can just pick one solution and run with it (at least, non-fossils, anyway). Nuclear is slow to ramp, so it usually takes care of baseline load. Renewables like wind and solar are situational, they mostly work throughout the day (yes, wind too, differential heating of earth’s surface by the sun is what causes surface-level winds) and depend greatly on weather. Hydro is quite reliable but it’s rarely available in the quantities needed. The cleanest grids on the planet use all of these, and throw in some fossils for load balancing, phasing them out with energy storage solutions as they become available.
You can’t just shoot one of the pillars of this system of clean energy and then say you never tried to topple the system, just wanted to prop up the other pillars. Discussing shutting off nuclear plants without considering the alternative is pure lunacy, driven by fearmongering, and propped up by no small amounts of oil money for a reason.
Replacing nuclear with renewables is simply not the reality of the situation. Nuclear and renewables work together to replace fossils, and fill different roles. It’s not one or the other, it’s both and even together they’re not yet enough.
So when you do consider the alternatives, moving from nuclear to the inevitable replacement, fossils, is still lunacy, just for other reasons: even if you care about nothing more than atmospheric radiation, coal puts more of it out per kWh generated, solely because of C-14 isotopes. Nuclear is shockingly clean, mostly due to its energy density, but also because it’s not producing barrels of green goo, just small pills of spicy ceramics. And if your point is accidents, just how many oil spills have we had to endure? How many times was the frickin ocean set on fire? How many bloody and brutal wars were motivated by oil? Is that really what a safer energy source sounds like to you, just because there are two nuclear accidents the world knows about, and a thousand fossil accidents, of which the world lost count already?
And deflecting to other industries is also quite disingenuous. Especially if your scapegoat is transportation, since that’s an industry that’s increasingly getting electrified in an effort to make it cleaner at the same logistical capacity, and therefore will depend more and more on the very same electrical grid which you’re trying to detract from.

Being from Germany, I have often read such arguments and at least here that is simply not true.
The decrease in nuclear power was accompanied by a decrease in fossil fuel.
Could that decrease have been larger if nuclear had been kept around longer? Possibly.
But if we are talking about building new power plants, the money is typically better invested in renewables. They’re faster to build and produce cheaper energy.
Germany, specifically, was one of the worst offenders in this category. They do renewables at maximum capacity (like everyone else) but there’s still a massive gap to fill, and with issues of strategic dependence around hydrocarbons, the obvious answer to fill in the missing capacity was coal. Most of the time you get a mix of coal and natural gas, whichever is easier, but in Germany’s case that mix was almost entirely on the side of coal.
And without abundant hydro power, or an energy storage solution that could store a full night’s worth of energy even if the current deployment of renewables was able to generate that (which it’s pretty far from), there aren’t a lot more options. Germany’s strategy to shut off its nuclear plants out of fearmongering has been a heinous crime against the environment.
When oil companies love your green party you know you fucked up.
There is massive work being done to improve large scale energy storage (big batteries) so the renewables become less and less situational. Large scale energy storage is significantly less constrained than car batteries, because weight is a one time cost. Even gravity based batteries could become viable.
Also, in response to the previous commenter, electricity generation is by far and large the main source of emissions accounting for more than half, with more than a quarter being agriculture. Transportation is 14%, and given the future transition to electric vehicles, one might argue that half of that can be tack’d on to electricity generation’s share. (Half because electric cars are more than twice as efficient at energy conversion than petrol cars. Toss in some power line losses and that’s a reasonable estimate)
All of that is great, and I’m all for it. Can’t wait for the first grids with no fossils whatsoever, once energy storage improves enough that it can take all the balancing load. When we reach that, it will mark the start of the era where nuclear is actually being replaced by renewables rather than fossils.
My point here is that switching off nuclear is premature for now. It’s a very clean source of energy once you look at the per kWh numbers and nuclear waste management solutions are actually extremely safe. (The videos where they test the containers by smashing actual trains into them are kinda fun – and those tests are done with liquid water, which is far more susceptible to leaking than solid ceramics.) Of course, if we reach a point where wind, solar, and hydro can fully replace fossils and start eating into nuclear’s share then that’s gonna be a very different conversation, and I’m fully with renewables in that situation, but we should always keep the alternatives in mind when we shut something off.
That’s why we’re not just shutting down coal plants altogether, because there’s just nothing to replace them. Although an energy policy where you just flat out ban renewables fossils and tell the market that that’s the supply, now go figure it out would certainly be interesting. Very expensive and terrible for the economy, but interesting nonetheless. (Definitely the based kind of chaos if you ask me.)
edit: okay, that was a weird word to accidentally replace, lol
It’s not a false dichotomy when it’s a zero sum game. Our consumption is essentially inelastic, because we are all complete assholes, so all we have control over is what kind of production we build.

Even if that’s the premise there are still other power sources -> more than two choices -> false dichtonomy.
But then, blaming “people who disregarded nuclear energy” - instead of people who don’t want to change anything in the face of a historically unprecedented worldwide disaster - seems a bit short sighted.
