It's hilarious to me that South Park has been on the air long enough that they had to essentially apologize and admit they were wrong about their edgy climate change contrarianism when reality started catching up.
i still don't get the nuclear lovers, like yeah it's better than coal and oil but renewable are now cheaper and much faster to build. we don't have decades to build new nuclear plants anymore.
I am personally in favor of nuclear because I don't think we have solved the problems with renewables yet, our power grids are not ready to support a 100% renewable system and as of right now, electricity grids require some stable energy. Hydro can technically fill that role but that's restricted by geography, so in places where that is not an option, it's a choice of fossil fuels versus nuclear. In that context, nuclear is the lesser evil by far.
Unlike some of the other responses, I don't think we can't wait for energy storage solutions to be developed when we needed to be zero emissions, like, ten years ago. We need to use solutions that we know about RIGHT NOW, not years into the future.
It makes little sense for fully functional and existing nuclear plants to not be running though because politics/cheap gas/lobbying.
About 90 terawatt hours (TWh) of nuclear generation is scheduled to retire in the next decade, more than all of the US’s current solar generation. Studies suggest that another 135TWh is probably not cost competitive with gas plants and, therefore, at risk of retirement.
This means the source of about 15% of US low-carbon electricity could shut down and largely be replaced by gas, making it harder for the US to meet its emission reduction targets.
Research suggests that many existing nuclear plants would avoid being shut down if they were rewarded for their minimal CO2 emissions. Additionally, keeping existing nuclear plants open may be one of the lowest-cost forms of carbon mitigation, cheaper than building new wind or solar plants to replace them.
Nuclear, like all things do, requires investment and scale to bring the cost down. Investment is necessary for iterative innovation that reduces costs, and after Chernobyl, the west at large more or less stopped building nuclear reactors. That means the past +30 years in nuclear has been more or less stagnant, so maintenance and build costs go up as everyone trained to build and work on them either moves on in their career or retires. It's a big reason why the US dumps so much money into oil, agricultural, and military spending and subsidies. Not just to funnel money to donors, although that is a big part of it, but because that industrial capacity is a national security priority. Once you lose it, it's a lot harder and a lot more expensive to get it back, with no good alternative in the meantime. That is what happened with nuclear.
And we are only now starting to see if the next generation of SMR (small nuclear reactors) can bring the cost down. Standardizing the production of smaller units that are much faster to make and deployable in more places will go a long way. Before, every single nuclear reactor was more or less bespoke, because a certain large enough size reactor grants enough operational efficiencies that it made much more sense to build large reactors with public funds to service a large area. But now government doesn't want to make those kinds of big investments anymore, NIMBYs everywhere don't want it built near them, and that is a long term strategy that requires long term commitment and public acceptance of nuclear to pull off.
As for why we need it, well, batteries are expensive and environmentally harmful to produce and very limited in supply. Renewables are intermittent and often unpredictable, and the grid demands a base load of power. Increasing efficiencies on the demand side requires public buy in and a whole lot more effort, like better insulating everyone's house. Hydro is also ecologically not great, not suitable everywhere, and demand for power tends to spike at the exact time that it is most useless - during hot dry droughts. Nuclear is the only thing that can replace fossil fuels for the purpose that fossil fuels fill in heavily renewable countries. Germany for example shut down their nuclear reactors and went back to burning lignite coal, because wind and solar could not provide the electricity they needed. Their emissions went up in 2021 and 22, despite how heavily they are investing in renewables.
"Nuclear lover" is a bit harsh. Someone mentioned batteries but another area is in actually buying emissions free energy and proving it for audits or reporting.
An angle that needs to be considered is that any upgrades that need to happen to a power grid in order to connect (in the US) need to be paid for by the party adding to the grid. The US distribution grid is ancient and this actually incentivizes them to do nothing.
One of the major negatives in solar and wind power is the instability of it. I think it's overblown but is a genuine issue. Factor in the massive, massive bill the newer renewable power generator pays and it makes sense to use something more stable to recoup investment. Nuclear is then safer, capital does what it does.
There's also the negative that depending on the contracting for the batteries, the lessOR of the batteries might be able to "claim" the energy credits towards their zero energy claims. This is also how those other solar companies profit off installing them on your house, they take the "green energy credits" and can sell them.
Nuclear doesn't usually have these types of stipulations.
Fwiw most people in the corporate sustainability push (who actually give a damn that is) think net zero is impossible without a significant nuclear push.
Renewables aren't cheaper at a scale per KWh than nuclear once you include energy storage. Nuclear is also still cheaper and has less carbon footprint for production and operation once you cross the 10 years of operation mark. All for renewables, but the "cheaper than nuclear" argument is a myth with some numbers fudged.
Here in Germany 1 kWh of nuclear energy did costs about 40 cents, 1 kWh from Wind energy costs 3 cents.
Also you forgot the cost of storage for the nuclear waste. Super expensive because no one wants that stuff near them and it has to be securely stored for thousands of years.
Haha Greenpeace reconsidering anything. They're like the Germany govt., they'd rather see the world burn than admit to change anything in their perfect plans.
Climate change isn't real but we don't want to change to avoid it
Climate change isn't real, but the science says otherwise but that changes nothing
Climate change is real, but we want you to do the hard work by doing pointless things
Climate change is real, but its your fault and not ours because you're poor
Climate change is real, and we're now in a feedback cycle from overextended forests, permafrost releases, and overdevelopment, and doing anything impacts the most poor so there's nothing we can do about it.
Climate change is real, we the wealthy and privileged did it, and there's nothing you can do about it <-- you are here
Climate change is real, and we're dipping to colonize another planet while you all die
It sounds good, but the sheer logistics of it are mind blowing. It sounds cool to terraform Mars, but that's a multi-hundred year process that will require quadrillions of dollars. It would be cheaper and faster fixing the Earth.
no whatll actually happen is intentional mass dust cover to cool down the earth using NUKES and stuff like volcanoes cooling areas with ash cover because space travel is a fun hobby but its impossible en masse (i speak uneducated on the matter but im confident in myself)
Well, there are billionaires preppers who probably would be prepared to become your feudal lords. Are the peasants uncontrollable? Well, Musk is working on a brain chip tech.
I'm gonna suggest there's a cognitive dissonance going on here
Climate change is real but it's only the wealthy that should do something about it <-- you are here
Collective action is part of the answer. The influential will do what they do, sure. But the 60 million normal people in the UK absolutely have an impact
The truly horrifying part about all of this is that the large corporations who are mostly responsible for greenhouse gas emissions are continuing to conduct business as usual. I'm doubtful anyone has the (political) will or ability to force them to stop...
I drive a semi truck for a living. I can imagine slightly more inconvenient alternatives to driving trucks everywhere, but trucking companies and their customers can not.
It's a political problem, as it should be, but the candidates that they've chosen to represent us aren't the ones we need, they're the ones that the "other side" really doesn't want. It used to be a game, but now with the internet/TV, it's divided into a political tribalism and has become nothing but metagaming.
It's called trains and barges. Long haul trucking shouldn't exist, because everything long haul trucking does is done infinitely better by trains and barges.
Trucks have their purpose as the last mile delivery vehicle, but they should never be shipping anything between cities.
No, it's even worse than that. There's a stable part of America that still refuses to believe in it. They tend to be "Christians" that are just killing time waiting for the rapture anyway. These are only tangently related, as their true religion is "I get to tell you what to do; you don't get to tell me what you do," which the GOO then exploits to stay rich and powerful.
COVID illustrated that Republicans will never acknowledge the 'oops' phase. They will keep their foot on the accelerator even after we've plunged off the cliff and are in freefall.
…up until they abruptly and simultaneously switch to “all of these natural disasters are indications that the End/Rapture is coming, so we’re going to go even more conspiracy crazy and get even nuttier people elected so that they can accelerate this to ensure we all die as is ordained.”
And exporting it to gullable people the world over, with a dose of feel good life tips, US conservative christian values, manufactured outrage, and cute cat pictures!
The UN is not a joke, people just don't understand the purpose of UN. The purpose is for countries to have a public forum where countries can discuss things. Even if something is decided in the UN it becomes the responsibility of individual countries to enforce those decisions. The UN cannot enforce decisions, we tried that with the League of Nations and it was a big failure.
The UN doesn't have the power to do anything against climate change because it was never the purpose of the UN. The UN can only open up a discussion about how to tackle climate change, but any and all actions have to be done by actual countries.
It's fun to pick on Americans (I'm one of them) but a lot of Middle Eastern countries and their citizens are also hellbent God worshipers who deny climate change. And basically most countries' government actions show they don't really care about it either. Singapore is really the only one that comes to mind for leading the way to try and make change, but they're too small to make any measurable change by themselves.
