Son of Rodney posted:It's quite feasible, cheap and most importantly a lot faster to use renewables up to a certain percentage (most sources say about 80%), ... Nuclear imho takes too long and is too expensive in the short run to go full hog on. Sorry but I don't think this is correct, though it certainly may be the case for germany based sources. Problem is, with PV solar specifically, it sucks real bad and you're just outsourcing your CO2 production. Under the jacobson scheme, the total cost of large scale residential PV in the US would be about $1.5 trillion, and provide a paltry ~4% of the grid power. This is half the estimated cost of the low end of 1.5GW of nuclear. But it gets worse. Taking into gCO2/kWh equivalent (that is the CO2 emissions associated with the production and manufacture thereof), PV averages around 40-50 gCO2/kWh, where as nuclear is right on par with wind turbines at ~12. Of course it gets worse still. Because that's kWh produced directly via wind turbines, which on average put out about 17% of their actual capacity, which is what you will always hear quoted when they talk about windfarms. It goes up to some amount, if the wind is pushing every single blade at max rated speed. The other 83% of the time? Yeah you called it, natural loving gas, piped leakily to you direct from Putin. You're not wrong about the lead time of nuclear, it's too bad we didn't have a model to follow 30 years ago that we could have scaled up like the French oh whats that a French citizen has half the average CO2 footprint as a German one weird I wonder how that is possible. Anyway 'nuclear takes a long time and we waited too long so let's not bother making it a primary asset in our energy portfolio' is a new take for me. I am afraid your rosy notions about the cost of transient renewables may be off the mark.

Fusion research doesn't really suffer from a lack of research dollars, but a lack of feasibility. Let me preface by saying I love fusion, we should continue to work upon the problem, but even after hitting Q=1 soOomeday sOoOon we're still at that point 40-50 years away from a workable commercial plant.

Under the jacobson scheme, the total cost of large scale residential PV in the US would be about $1.5 trillion, and provide a paltry ~4% of the grid power. This is half the estimated cost of the low end of 1.5GW of nuclear. First of all: I have no idea who jacobsen is or what he's scheming, and don't know much about the US grid situation. AFAIK however, current prices for solar are 1USD per watt of installed capacity (expected to decrease by a lot), so that would mean you could install roughly... 1.5TW of energy for the cost of 1.5GW of nuclear if I'm reading your number correctly? I'm not sure what you mean with "This is half the estimated cost of the low end of 1.5GW of nuclear." Could you elaborate on that? LCOE of renewables on a larger scale have been cheaper than nuclear for a few years now, and will continue to sink drastically. Your statistic on wind production is pretty much the lowest percentage of full capacity hours per year btw. On average 1500 hours per year can be expected inland, but depending on the actual location can be significantly higher. The US and australia for example propably have a huge area that is untapped prime wind estate that could yield about 2500+ hours of full capacity per year. Saying that 83% of the time the turbines are not supplying energy is kinda misleading too, they're often running with partial capacity and still supply power. This cannot be controlled however depending on current demand, so that is a real problem. The viability depends alot on how quick storage develops into usable large scale solutions. All in all my point is more that we need to increase low co2 emission energy sources asap, and wind and solar are very capable of being quickly deployed in areas where they make the most economic and engineering sense. A nuclear plant is not the best solution for those areas that are more decentralized and heavily dependent on smaller scale coal or gas stations. Nuclear would make the most sense in huge metropolitan areas with a high base power demand, where a 10 year + lead time is a lot easier to plan for. I believe that replacing coal asap with anything low emissions is a number one priority, and using cheap and quickly deployable renewables while at the same time building nuclear makes the most sense, instead of putting all of your eggs in one basket. Also the situation in germany is stupid as gently caress, politics are currently stifling renewable deployment with stupid policies, and decomissioning existing nuclear was absolutely butt-loving stupid.

Here is a graph based on a 1976 ERDA (predecessor to today’s DOE) fusion development plan, showing their four paths to a reactor, as well as a business-as-usual funding case that would never lead to a reactor, and in black is the actual funding amounts.

LCOE of renewables on a larger scale have been cheaper than nuclear for a few years now, and will continue to sink drastically. I think we're pretty much in agreement on broad strokes, but it's more like $3.00/W average currently. Jacobson is the premier author of a 100% renewables roadmap plan that has been a heavily touted and deeply flawed take on how to go whole hog on green energy sans nuclear here in the US. The $1.5 trillion figure is the estimated cost of what it would take to get four percent of a quote:Your statistic on wind production is pretty much the lowest percentage of full capacity hours per year btw. On average 1500 hours per year can be expected inland, but depending on the actual location can be significantly higher. The US and australia for example propably have a huge area that is untapped prime wind estate that could yield about 2500+ hours of full capacity per year.

This cannot be controlled however depending on current demand, so that is a real problem. The viability depends alot on how quick storage develops into usable large scale solutions. Yet another major problem with concentrated solar and windfarms is methane leaks. A 4% leakage of methane from gas-backed farms would wipe out the gains from eliminating coal burning with it. That is to say, if even 4% of the natural gas backup supply is lost, you may as well have just kept the coal plant instead. The industry's admitted leakage rate is 1.6%, which is so far as I know just post-mined stream processing. Does anyone even know what the escaped estimated losses from the mining thereof is? And, yeah, storage. It's not good. The energy density to cost of even our cheapest workable option, pumped hydro, is real real bad. Compare that to the 25,000 barrels of oil equivalent to 1 pound (about the size of a sugar cube) of HEU. quote:All in all my point is more that we need to increase low co2 emission energy sources asap, and wind and solar are very capable of being quickly deployed in areas where they make the most economic and engineering sense. A nuclear plant is not the best solution for those areas that are more decentralized and heavily dependent on smaller scale coal or gas stations. Nuclear would make the most sense in huge metropolitan areas with a high base power demand, where a 10 year + lead time is a lot easier to plan for. Finally, small scale nuclear is awesome and portable, I think you've got an outdated notion of nuclear power scaling. You can basically fit an SMR on the back of a truck and put it where ever you need the power. This is objectively superior to PV in a CO2-equivalent footprint point of view, and superior to wind from a reliability point of view (and again from a backup GHG leakage). That said, by all means install other types of renewables where it makes sense, I just think it makes sense in far fewer places and under much more restricted circumstances than people realize. quote:Also the situation in germany is stupid as gently caress, politics are currently stifling renewable deployment with stupid policies, and decomissioning existing nuclear was absolutely butt-loving stupid. Moridin920 posted:It's a difficult engineering/science problem to be sure but all these people say it absolutely does suffer from a lack of funding. No this is fair, I should have qualified that, comparatively to next-gen fission reactor research. e2; oh lol I knew I was making a simple mistake, the 2050 estimated grid size need is 1.6 TERRAwatts so that gives us $192,000,000,000 for 4% PV ahh what the gently caress is oging onn The Protagonist has issued a correction as of 22:17 on Mar 11, 2019 |

I've been reading this book recommended in the last thread called the water will come and the first few chapters are about the creation of Miami Beach, and one point the author makes effectively is that it was a bad idea to build there in the first place and all the initial development was essentially a get rich scheme Within the first few years of development the place was almost destroyed by a hurricane, and instead of taking it as a warning against further development they doubled down in the most hilarious ways, so nothing has really changed lmao

I build wind turbines. To head off lengthy pages of throwing numbers around and people wasting precious hours of their lives: if you think wind turbines are anything other than a wierd way to transfer money around and greenwash things, you're a real dumb gently caress. Full stop. Just shut the gently caress up, you're an idiot. I know, I spent 178 hours up them in the past 14 days alone. They're poo poo. They have a useful lifespan of 25 years, the engineering flaws with them are massive and paradoxically getting worse, and after you factor in repeated major component replacement they almost never pay off the inherent carbon cost of manufacturing and running the fuckers. Nobody in the industry gives a flying gently caress beyond the paycheck, myself included. Nobody. Just build shitloads of nuclear plants. We have designs which cost a fraction of the standard model and literally run off nuclear waste fuel. Solar and Wind are there to appease the peabrains of easily distracted green yuppies and distract from the end of civilization in a decade. Because you can't build enough nuclear to suck all that carbon back out of the atmosphere fast enough to save ourselves. You idiots, you absolute simpletons.

Fission works and is easy and we know it pretty well, just a bunch of self-heating rocks stuck inside a pressure cooker.
