funkatron3000 posted:So, looking at the threats to the long term survival of humanity like climate change, disease, meteors, etc... it seems that a reasonable priority for humanity should be to establish self sustainable human outposts somewhere other than earth. There's really nothing else that gives us the same level of long term survival. There's no real reason that non-weather related events should be any worse than they were in the past (ie, Meteors aren't more likely to hit earth because we have tons of carbon in the air). Worrying about stray diseases also seems like an empty gesture because people are becoming more able to combat disease, not less. If the whole world industrializes and growth rates trend the way they have in developed countries, the killer of humanity might just be our own education, not a hurricane.

And I'm saying we generally have those systems already put into place (Granted, Meteors we can't actually *stop* but we've tracked basically all the ones that would do any damage and they're not projected to hit the Earth).

deptstoremook posted:And, an interesting point, even if all electric energy were supplied by nuclear tomorrow, that would still only account for a relatively small portion of our consumption. Consumption of what, fossil fuels? Because another big chunk (transportation) can be pretty easily switched over to electricity which can then be supplied by Nuclear Power.

deptstoremook posted:Well now you're going even further into speculative territory. Even if we overcome the very real limitations of uranium production and the construction and deployment of new plants which Cellier describes, now you're proposing that--in the same short span of time--the world's transportation systems could be "pretty easily" converted to electric. If the political will for nuclear plants is already scarce, by what means do you suggest we implement an unprecedented, speedy, and unilateral overhaul of all of our existing means of transportation? By "easy" I mean that there already exists technologies or close equivalents which can replicate our transportation system, but with an electric source. The issue now is as you said, deploying the technology. It's not like (for a bullshit example) "cars aren't feasibly able to be run by electricity and so we need to develop fusion powered engines which don't yet exist". The technology already exists, the only reason it isn't being deployed is inertia*. *And even then you're getting things like plug in hybrids to full on electric vehicles already, even before we switch off of fossil fuels.

blowfish posted:However, we still run into the problem that electrically powering even a reduced amount of transportation would still require substantially more power plants because we have to make our own energy dense fuel, regardless of whether energy is stored as batteries or chemically and can't just burn pre-made oil which essentially just needs to be pumped from an oilfield into an engine (with various steps of refinement in between, but still). Uhh, how is refining Uranium any more intensive than refining oil?

a lovely poster posted:Who's saying it is? Then I'm confused as to why we would need substantially more power plants to make batteries. Unless you have an article saying otherwise, battery creation is probably not any more energy intensive than what we already do to survey for oil, and what we do for uranium mining is probably far below that and even below coal mining. In short (unless you prove otherwise) - Uranium mining + battery making < coal mining + oil surveying+making.

This is assuming demand is consistent when we are already seeing a shift toward electric cars and hybrids. Also you're ignoring basic economics. The only reason current reserves are exploited (ie, fracking) is because they are expensive. We already drilled the cheap stuff years ago. If oil doesn't cost a certain amount it isn't worth it to drill. Now, can oil companies use electric vehicles/etc to lower the cost of extraction? Maybe, but probably not to the extent you're thinking of. computer parts fucked around with this message at 20:13 on Sep 16, 2013 |

Rather that wide acceptance of the already guaranteed outcome causing society to more effectively focus on creating solutions is no certainty. Exactly. If you frame it as "well there's nothing we can do to stop [bad thing], but maybe if we work together we can stop [worse thing]", people will tune out after "we can't stop [bad thing]". If you want to make people enthusiastic, you need to frame it as "If we don't change something now then [worse thing] will happen", and omit that [bad thing] is already going to happen.

satan!!! posted:I'm not an expert but I think I have a basic understanding. I'm referring to the hysteria on theoildrum.com and in other circles around that time when people were seriously predicting $250+/barrel, which obviously never eventuated. Obviously oil production will eventually peak, but I'm no longer convinced that will be accompanied by as many negative consequences as some people claim. Peak oil is kind of hard to determine because oil production is based on what the price of oil will be - obviously stuff that costs more to extract wouldn't be viable unless oil is more expensive. There will be a point (and arguably we've hit it already) where people can't feasibly buy the oil, however, and when that happens then society either has to adapt or a lot of bad things will happen. Basically, peak oil is kind of a misnomer because it assumes that the supply of oil will be the limiting factor, instead of the demand of the oil at the current price.

The New Black posted:I think it's on topic to discuss energy sources and use, since it's at the heart of carbon emissions. In several big cities charging ports are already springing up (and even in my university there are a few around). One of the benefits of electric cars (and what makes them kind of useless for long trips) is that you're expected to plug them in when you get home. This means that you don't need to replicate gas stations but with charging ports or whatever, you just need to build plugs into garages (and that's already A Thing today). The bigger issue with electric cars is more that they're still incredibly expensive, you can't get the same mileage on a single charge that you can with a tank of gas (though they're working on that), and the materials needed to make the batteries are incredibly bottlenecked at the moment (though again that's more due to lack of present demand).

From what I've seen, yeah it's perfectly possible. We have Nuclear plant designs that could work fine (or Solar/Wind/etc if nuclear makes you scared). Most cars could probably be replaced with electric versions no problem (the exception being truckers but that's still the vast majority of vehicles in the US), and if you want to just disincentivize cars you can rebuild cities to be more accommodating; it's not some dark magic that's unknown. The tech problem is mostly solved, it's the propagation and diffusion of that tech that remains the issue, and that's mostly a concern of demand and cost.

The New Black posted:Really? Given the massive amount of food that is grown just to be fed to animals for mostly Western meat consumption, with the big efficiency loss that goes with it, wouldn't reducing that demand lower the price of those foods for people? A lot of the crops grown are literally not edible for humans but are for animals. There is also currently a glut in production (for food in general, but especially human friendly stuff) so it's not like making things more efficient will necessarily solve world hunger because you still need to get the food out to people.

Paper Mac posted:That's the point, yes. If our primary energy input into ag was labour rather than fossil fuels, this wouldn't be a problem. I see what you're saying but your point is just as applicable without the input from food. How much food you get doesn't matter if the input relies on a quickly draining resource. In other words, a better graph would be the amount of energy required to transport x amount of food versus the amount of reserves of that energy we have.

As mentioned above, the problem is industrial agriculture, not just meat specifically. Growing plants the way we do now is still far over the acceptable carbon boundaries even if it's technically less so than meat. Stopping production of meat while keeping everything else will make things less bad, yes. It will also still gently caress you over.

petrol blue posted:I don't really see that there is any argument. Unless your arguing that people need meat, then surely it's just a matter of accepting that maybe there's too many people on the planet to keep up with us all having everything we want food-wise. The emissions and environmental effects are the only relevant parts. What does it mean that food production is "at breaking-point" if it doesn't apply to environmental effects? You seem to be of the notion that the loss of efficiency of the food itself is the main problematic factor when in reality you'd do a lot more to increase efficiency by simply not using gas to run your transport trucks, or a million other things not related to actually growing the food. We have a food surplus right now, and we have a population which is not exponentially increasing, despite what you may think. Food production is not the pressing issue.

India is already doing that though, and China is following (albeit more slowly and this may be disrupted by their coming depression).
